Whether from Transcaucasia or the nearby Taurus or Zagros Mountains, it is hypothesized that this wine culture spread southwards and eventually westwards around the Mediterranean basin, together with the transplantation of cultivated grape cuttings. However, the existence of morphological differentiation between cultivars from eastern and western ends of the modern distribution of the Eurasian grape suggests the existence of different genetic contribution from local sylvestris populations or multilocal selection and domestication of sylvestris genotypes. To tackle this issue, we analysed chlorotype variation and distribution in 1201 samples of sylvestris and sativa genotypes from the whole area of the species’ distribution and studied their genetic relationships. The results suggest the existence of at least two important origins for the cultivated germplasm, one in the Near East and another in the western Mediterranean region, the latter of which gave rise to many of the current Western European cultivars. Indeed, over 70% of the Iberian Peninsula cultivars display chlorotypes that are only compatible with their having derived from western sylvestris populations.

  • Evaluating Resistance to Grape Phylloxera in Vitis Species with an in Vitro Dual Culture Assay WLADYSLAWA GRZEGORCZYK ~ and M
    Evaluating Resistance to Grape Phylloxera in Vitis Species with an in vitro Dual Culture Assay WLADYSLAWA GRZEGORCZYK ~ and M. ANDREW WALKER 2. Forty-one accessions of 12 Vitis L. and Muscadinia Small species were evaluated for resistance to grape phylloxera (Daktulosphaira vitifoliae Fitch) using an in vitro dual culture system. The performance of the species tested in this study was consistent with previously published studies with whole plants and helps confirm the utility of in vitro dual culture for the study of grape/phylloxera interactions. This in vitro system provides rapid results (8 wk) and the ability to observe the phylloxera/grape interaction without interference from other factors. This system also provides an evaluation that overemphasizes susceptibility, thus providing more confidence in the resistance responses of a given species or accession. Among the unusual responses were the susceptibility of V. riparia Michx. DVIT 1411; susceptibility within V. berlandieri Planch.; relatively wide ranging responses in V. rupestris Scheele; and the lack of feeding on the roots of V. califomica Benth., in contrast to the severe foliar feeding damage that occurred on this species. Vitis califomica #11 and V. girdiana Munson DVIT 1379 were unusual because phylloxera on them had the shortest generation times. Such accessions might be used to examine how grape hosts influence phylloxera behavior. Very strong resistance was found within V. aestivalisMichx. DVIT 7109 and 7110; I/. berlandieric9031; V. cinereaEngelm; I/. riparia (excluding DVIT 1411 ); V. rupestris DVIT 1418 and 1419; and M. rotundifolia Small. These species and accessions seem to possess enough resistance to enable their use in breeding with minimal concern about phylloxera susceptibility.

Through a dual RNA-sequencing approach, this study aimed to give a broader perspective on the infection strategy deployed by L. theobromae, while understanding grapevine response. Approximately 0.05% and 90% of the reads were mapped to the genomes of L.
