identified by a genotyping-by-sequencing approach followed by Sequenom rootstocks with long-term resistance to phylloxera, as well as root knot The DNA of a new rootstock can immediately be checked to see if the rootstock contains resistance to phylloxera. The North American Vitis cinerea is also resistant to biotype A, but it is not known if this is also due to RDV1 or due to another gene in the grape genome. | Chamber of Commerce No. resistance. management: clonal lineages and population biology of Grape phylloxera. A LOD (“logarithm of the odds”; a statistical value) of more than 2.89 indicates that the association is significant. Site and rootstock effects were particularly obvious in regards to yield. The Phylloxera and Grape Industry Board of South Australia, trading as Vinehealth Australia, is committed to minimising the risk of pests and diseases (in particular phylloxera) in vineyards, by investing in biosecurity training and awareness, policy and procedures, research and development priority setting, and preparedness, prevention and response activities, to the benefit of the South Australian and national wine industry. These particular species evolved in the presence of the phylloxera and so developed tolerance mechanisms that allowed them to continue to flourish in the presence of the insect. species including Vitis cinerea8,9 to further increase the are highly adapted to feeding on the roots of Vitis vinifera wine Phylloxera feeding can also occur on young feeder roots, resulting in the formation of characteristic nodosities. Researchers try to identify the pieces of DNA in the grapevine rootstocks that are responsible for their resistance to phylloxera. The same analysis, but compared to the other parent, the Vitis Vinifera Riesling, does not show any significant associated parts of the DNA (no image shown). Questions are being asked globally about the long-term stability of grape phylloxera resistance in commercial rootstocks. Walker says that the sandy bank is phylloxera-free, but an infestation marred the other side. parentage4,5,6,7,“ Harley said. To read more about the CSIRO rootstock breeding programs click here. Merlot, Chardonnay, Pinot Noir, Riesling, etcetera) were grafted. Figure 1. if e.g. with Agriculture Victoria’s phylloxera research program to ensure that the Until recently, the foliar forms of grape phylloxera have been absent or very rare in California, and nodosities have not been common on resistant rootstocks. S., Robertson, E., Potter, I., & Powell, K. S. (2012). Resistant rootstocks are the only completely effective means for phylloxera control in the most severely affected areas. assisted breeding” can be used. Vine vigor is moderate, but slightly more vigorous than those grafted on 101-14. (2018a). Foliar phylloxera are now widely spread in the mothervine plantings of grape rootstock nurseries in Yolo and Solano counties. What really benefits the winegrower is the cultivation of new more Progeny derived from these crosses containing two resistance traits for phylloxera will be selected using DNA markers. A Scientific Basis feeding on rootstocks with Vitis riparia CSIRO research scientist Harley Smith told delegates at the recent Australian Wine Industry Technical Conference that the CSIRO Rootstock Breeding Team had identified and genetically mapped resistance traits for grape phylloxera and root knot nematode from the wild North American grape species Vitis cinerea. Theoretical and Applied Genetics 132: 1847-1860. Therefore, to re-establish the vineyards in Europe, these resistant North American vines were used as rootstocks on which the European Vitis vinifera grape varieties (e.g. The history is well documented, though the pivotal role of vineyard soils much less so. Reference: Smith HM, Clarke CW, Smith BP, Carmody BM, Thomas MR, Clingeleffer PR, Powel KS. To date, this is used in almost all vineyards in the world to prevent root damage caused by phylloxera. This is useful when making new and more resistant rootstocks. cinerea for marker-assisted selection. Lloyd A. Lider. Phylloxera-Resistant Rootstock Trials in the Coastal Valleys of California. rootstocks to combat a changing climate and pest pressure is now being insect pest1. We’re not only using this strategy for phylloxera but also for root knot nematode resistance,” Harley said. This biotype performs poorly on the AxR1 rootstock (a crossing of Vitis vinifera with the North American Vitis rupestris) and all crossings of the North American Vitis berlandieri and Vitis riparia, e.g. Only the plants that inherited the right piece of DNA from the Vitis Cinerea C2-50 can be resistant. Background: Grape phylloxera (Daktulosphaira vitifoliae Fitch) is a major insect pest that negatively impacts commercial grapevine performance worldwide. nationally. Wine Australia. This weakens the plant, leaves die off, and roots are deformed. Resistance of these rootstock varieties to leaf phylloxera form was important also in rootstock nur-series. Vitis viniferavines can be protected from these pests by grafting them to rootstock varieties derived from other vine species and resistant hybrids. The piece of DNA responsible for resistance to phylloxera biotype A was found by looking at which parts of the DNA were inherited each time resistance occurred in the F1 plants, and were not inherited in the phylloxera susceptible plants. Rootstocks can also control vigor, yield, and fruit composition, playing a fundamental role in the overall success of vineyard operations. The current rootstocks are not, or only partially, resistant to new phylloxera populations. Phylloxera still rears its exoskeletal head. Adelaide SA 5000 to phylloxera and root knot nematode for Australian conditions. Grape phylloxera, Viteus vitifolii Shimer, were reared on excised grape roots maintained in petri‐dish chambers. 7. 76049191 | Privacy statement | Cookie policy, Sonication of yeast cells accelerates aging on lees. Because (2019). Since the 19th century phylloxera has adapted. Annals of Applied Biology, 161(2), Phylloxera can feed on both the roots and leaves of Vitis species depending on the genotype of the host and insect2.

(2007). traits10. Cane hardiness is very good on this rootstock (Howell, 1987). and Powell, K.S. (1999). 91–115. Rapid expansion meant that it was estimated at that time that only 55 percent of vines were on resistant rootstock. Despite this long history, many questions remain about phylloxera's biology, its life cycle and how grape species and rootstocks resist its feeding. “Studies have shown that in Europe and 4. The concept of vine rootstocks came to the fore during the phylloxera crisis, when Europe’s defenceless grapevines were saved by grafting them onto phylloxera-resistant North American roots. experience another wine-growing crisis as it happened in Europe in 19th century Am J Enol Vitic. “We’re collaborating Genetic studies seem to offer a solution in the development and realization of rootstocks with a higher resistance to phylloxera. The use of rootstocks is the only practical method of overcoming problems such as phylloxera, nematodes or site difficulties. MassARRAY validation. American Journal of Enology and Viticulture 50:101-106. Catherine Clarke at Agriculture Victoria, the CSIRO team is evaluating the resistance genes are known, a genetic technique called “marker University of California Cooperative Extension Newsletter (2012). Figure 2. Once infested, the only solution is to replant resistant rootstock, whihc is selected based on site conditions and phylloxera strain. In South Africa, grapevine phylloxera galls occur mostly on rootstock varieties. Powell K. S. and Hoffmann A. the SO4, 125 AA, 5BB Kober and 420A rootstocks. In these cases, a high level of feeding on young roots produces numerous nodosities rather than tuberosities, which appears to reduce root function and vine performance under abiotic stresses.”. Phylloxera – also called Daktulosphaira vitifoliae, Phylloxera vastatrix, Viteus vitifoliae or Phylloxera vitifoliae – has a strong preference for the Vitis vinifera vines and affects both the roots and the leaves (Figure 1). These plants – the so-called F1 generation – received one copy of their DNA from Vitis cinerea C2-50 and the other copy from Vitis vinifera Riesling. 6. Genetic diversity and parentage analysis of grape rootstocks. By the time the new phylloxera's ruse was up, it had spread across California, decimating vineyards and requiring their reconstitution on newer phylloxera-resistant rootstocks. Thus, in their opinion, Phylloxerawas merely a consequence of the "true" disease, which remained to be found. Eventually the discovery of these genes (RDV1 and RDV2) may save their (new) vineyard. a new grape phylloxera resistant locus in Vitis A side view of an adult winged specimen (A), larvae on the roots (B) and eggs from the phylloxera laid in leaf galls (C). This led to replanting most of the vineyards in the 1980s in California due to the failure of the AxR1 rootstock. M. A. six distinct families, with individuals in each family likely sharing similar rootstocks can be grown that are resistant to multiple phylloxera biotypes. Phylloxera (Daktulosphaira vitifoliae, Phylloxera vitifoliae). Rootstocks currently used in commercial vineyard production are derived The CSIRO Phylloxera, the great plague of Europe is back! are of pure Vitis viniferaparentage. (2018).

PO Box 280 Harsh winters were an insufficient safeguard here. program is utilising next generation genetic and molecular tools for developing new Biotype A is the biotype as first characterized in Napa Valley that performs especially well on Vitis vinifera roots. In Australia, in contrast to Europe, biotype A is the most common phylloxera population found in the vineyards. Rootstock selection can also affect potential wine quality by improving vine health (donating resistance or tolerance to various pests, diseases, and unfavorable environmental conditions). whether these genes also regulate resistance to the other phylloxera biotypes, whether Vitis cinerea can also provide resistance to other So now there are two known genes – pieces of DNA from the grapevine – that regulate the resistance to phylloxera biotype A (RDV2) and biotype C (RDV1). resistance to the most prevalent endemic phylloxera strains, G1 and G4, which Phylloxera has been managed effectively since the use of resistant rootstocks in the late nineteenth century. Importing empty used grape bins or bulk tippers? However, a major disadvantage of these persevering phylloxera populations is that newer biotypes may emerge and the resistance to phylloxera of current rootstocks will disappear (even further). 8. Phylloxera Populations on Resistant Rootstocks When phylloxera feed on young root tips, swellings or galls (nodosities) form, giving rootlets a characteristic clubbed appearance (Fig 1). The 3309 rootstock is considered resistant to Phylloxera. “To breed long-term resistance, Vitis cinerea is being crossed with other North American Vitis species and hybrids harbouring other phylloxera resistance traits1. phylloxera strains including G7, G19, G20 and G30. By combining two resistant traits into the same rootstock, it’s extremely difficult for phylloxera to evolve and break two different resistance traits simultaneously. A pesticide treatment will not eradicate phylloxera populations; the chemical cannot easily penetrate the heavy soils that this pest prefers. Subscribe now to the newsletter! Kent Town DC from North American Vitis species number of Vitis riparia, Vitis rupestris and Vitis berlandieri selections6. Therefore, new rootstocks are needed that have a higher, or preferably complete, resistance to the phylloxera biotypes that are present in the geographical area of the vineyard. To investigate which part of the grapevine DNA may provide resistance to phylloxera biotype A, an Australian research group crossed Vitis cinerea C2-50 with Vitis vinifera Riesling and infected the resulting plants with phylloxera biotype A. When infested, the vines react passively at the roots, producing little or no bile, thus depriving the pests of the basis for propagation. The use of resistant rootstocks from Vitis species other than V. vinifera is advocated as the main method of radicicole phylloxera management and may be considered as the most sustainable example of bio-logical control for a pest ever used [6]. The 3309 is a medium-cycle rootstock and is susceptible to … 126: 567-571. The only European grapes that are natively resistant to phylloxera are the Assyrtiko grape which grows on the volcanic island of Santorini, Greece, although it is not clear whether the resistance is due to the rootstock itself or the volcanic ash on which it grows; and the Juan Garcia grape variety, autochthonous to the medieval village of Fermoselle in Spain. Required fields are marked *. To determine the genetic … Their presence on resistant rootstocks has been widely reported and, importantly for Australia, can lead to spread to highly susceptible own-rooted vines. marker-assisted selection. 733: 183-195. resistant to phylloxera. In Riesling is therefore an ideal “background” to view the effect of the inherited Vitis cinerea DNA on phylloxera resistance. 10. varying levels of resistance to this insect pest1. G4, G7, G19, G20 and G30. Most rootstocks showed a site specific reaction, showing good performance only on one, not on all sites. Tel: (08) 8273 0550 The control of phylloxera by grafting on resistant rootstock is now well understood and accepted throughout the world. 3. Grafting to rootstocks began in the late 1800s, as the only effective means of combating the ravage being caused by the phylloxera infestation. On New Zealand's South Island, phylloxera was discovered in the Central Otago wine region in 2002. rootstocks. The piece of DNA that causes the resistance is named (very originally) RESISTANCE DAKTULOSPHAIRA VITIFOLIAE 2 (RDV2). limit the options for replanting of infested vineyards. Previous research has already shown that a gene (a piece of DNA) located on chromosome 13 in the Börner rootstock (Vitis cinerea x Vitis riparia) provides an increased resistance to phylloxera of (probably) biotype C, which is the predominant phylloxera biotype present in Europe. However, the use of these rootstocks resulted in the emergence of biotype B (in California) and biotype C (in Europe) that are able to feed and reproduce on these rootstocks. Phylloxera – it’s in Australia, has been described as the most economically destructive pest species of commercial grapevines in the world as evidenced by its decimation of vineyards in Europe in the late 19th and early 20th century, and the only effective control against it is to plant or replant vines on phylloxera resistant or tolerant rootstocks. resistance in grapevine (Vitis cinerea) In particular, the damage to the roots causes the grapevine to eventually die within a few years. Performance BMC Plant Biology 10:360. Due to phylloxera’s effect on vine vigor, the vast majority of the world’s wine grapes are now grown on phylloxera-resistant rootstock. Grape phylloxera, Daktulosphaira vitifoliae (Fitch), is a potentially damaging pest of cold-hardy hybrid grapes (Vitis spp.). P.R. This is much faster than field studies that have to show whether resistance is indeed occurring in each generated rootstock. On Vitis vinifera, these phylloxera strains feed on mature roots, resulting in swellings called tuberosities, which ultimately lead to vine death. Level 1, Industry Offices SNP markers tightly linked to root knot nematode This was well below the figure for other regions in the country. Fortunately, phylloxera-resistant rootstocks have been available and have effectively defended vineyards against this pest for about 110 years. CBG Photography Group, Center for Biodiversity. 1. BMC Plant Biology 18; 18 (1): 360. https://doi.org/10.1186/s12870-018-1590-0, Your email address will not be published. Given As a result of these newly emerging phylloxera biotypes, the currently used rootstocks are only partially resistant. In collaboration with Dr This caused an almost complete destruction of the wine-growing areas in Europe. A new crisis seems to be imminent and new rootstocks with a better resistance are desperately needed. Regardless, Riley had discovered American grape varieties that were especially resistant to Phylloxera, and by 1871, French farmers began to import them and … The rootstocks of some American vines are resistant to phylloxera because they have adapted over millions of years. Several sources of grape phylloxera resistance for rootstock breeding have been identified. Given that phylloxera is the major endemic biosecurity threat to the Australian wine industry, the use of resistant and/or tolerant rootstocks is an essential vineyard management tool for safeguarding vineyards from this devastating insect pest 1. grape cultivars8,” Harley said. This radically shortens the breeding process of new Nodosities on resistant rootstocks have also been frequently observed. of vine killing tuberosities6. These families are represented in testing by strains G1, That’s why the work of the CSIRO Rootstock Breeding program, led by Harley Smith, has caught the attention of the biosecurity world. Root-feeding phylloxera cause the most economic damage to Vitis vinifera and are therefore the greatest group of concern in Yet even grafting is not always effective. Phylloxera also feed on larger roots of own-rooted V. vinifera and on rootstocks with V. vinifera in their parentage like AXR#1. “While it’s not clear if a similar strain exists in Australia, studies in Europe and California infer that phylloxera is evolving and becoming better adapted to Vitis riparia rootstocks, which includes Teleki 5C, SO4 and 101-14. The situation for trunk disease could not be more different. and Thomas, M.R. http://cenapa.ucanr.edu/newsletters/Vineyard_Views_Newsletter_-_Events43564.pdf. The current rootstocks are not, or only partially, resistant to new phylloxera populations. Rootstock Breeding program is selecting phylloxera and root knot nematode resistance traits from the wild North American grape However, it was noted that North American Vitis species were not sensitive to these insects. nematode, using DNA marker-assisted selection1. rootstocks we are developing will provide effective resistance to a wide range The association between DNA of Vitis cinerea C2-50 and resistance to phylloxera. Phylloxera is native to North America and was at the end of the 19th century accidently introduced in Europe. Vitis Vinifera Riesling has no resistance whatsoever and is very sensitive to all phylloxera biotypes. The genome of the phylloxera, an insect that caused plagues that devastated European vines in the 19th Century and has remained a potent threat ever since has been mapped by an international team involving researchers Miquel Barberà and David Martínez, from the Institute for Integrative Systems Biology (I2SysBio), center of the University of Valencia. Genetic studies seem to offer a solution in the development and realization of rootstocks with a higher resistance to phylloxera. Postal address: presence of RDV1 and RDV2 (and possibly other resistance genes) in their DNA, new © 2018-2020 Koen Klemann. Do you always want to be kept informed of all WineScience articles? Figure 2 shows this analysis in which a clear relationship can be seen between the DNA on chromosome 14 of the Vitis cinerea C2-50 and the resistance in the F1 plants. This resistance that phylloxera is the major endemic biosecurity threat to the Australian wine “The Vitis cinerea phylloxera resistance vitifoliae) – a review of potential detection and alternative All rights reserved. The hard to detect microscopic louse marches through vineyards with a scorched earth policy, destroying every vine in its path. of phylloxera strains,” Harley said. Our new strategic priorities: have your say, Minister for Primary Industries and Regional Development. Grape phylloxera belongs to the family Phylloxeridae in the order Hemiptera and is closely related to Aphididae (the true aphids) (Ortiz-Rivas and Martínez-Torres 2010). This technique uses markers to determine This gene originates from Vitis cinerea and was named RESISTANCE DAKTULOSPHAIRA VITIFOLIAE 1 or in short RDV1. This means that adapted phylloxera biotypes can still live on the roots and leaves of the plant. Australia, our 83 known phylloxera strains have been genetically grouped into vitifoliae Fitch. This species is particularly prone to attack by two root pests: grape phylloxera and para- sitic nematodes. Consequently, the use of phylloxera resistant rootstocks is an essential component of vineyard management. that have co-evolved with phylloxera and, as a result, they typically display generation rootstocks with increased genetic diversity and long-term resistance By selecting new vines for the Your email address will not be published.

To date, seven phylloxera populations – called biotype A to G – are known. industry, the use of resistant and/or tolerant rootstocks is an essential Upcoming studies will investigate genetic diversity of commercial rootstocks. Benheim, D., Rochfort, Grape phylloxera (Daktulosphaira The widespread use of rootstocks has put a selection pressure on phylloxera, and new – genetically slightly different – phylloxera populations developed that were able to feed and reproduce on the North American rootstocks. Dunlevy J., Clingeleffer P., and Smith H. (2019). Genetic identification of SNP markers linked to Evaluating rootstocks for phylloxera resistance is a major hindrance to a breeding program (Walker, 1992). of Hungarian phylloxera strains on Vitis riparia rootstocks.

California, there is a grape phylloxera strain that appears highly adapted to diversity is being recognised as a concern, as the source of phylloxera A. The technology for this was optimized for vineyard locations and soil types, and has been amazingly successful ever since. As Christy Campbell points out in his book, Phylloxera: How Wine was Saved for the World, California, which was first attacked at about the same time as Europe, is suffering its second invasion. The vineyards were eventually saved by using phylloxera-resistant native American vines, not as direct fruit producers (the taste of wine from American grape species was unacceptable), but as rootstocks. 2.
