TL;DR: A QTL analysis revealed a dominant gene Rpv12 that explained 79% of the phenotypic variance for downy mildew resistance and was inherited independently of other resistance genes, and identified polymorphisms in 12 varieties of V. vinifera using next-generation sequencing.

TL;DR: This study combining the use of microvine and a high throughput genotyping technology was innovative for grapevine genetics, allowing the identification of 10 stable QTLs, including the first berry acidityQTLs reported so far in a Vitis vinifera intra-specific cross.

TL;DR: A wild grape haplotype (Rpv3-1) confers resistance to Plasmopara viticola and allelic expression imbalance in a resistant heterozygote confirmed that cis-acting regulatory variation promotes expression in the wild haplotype.

TL;DR: Activators, elicitors and signal transducers for the formation of reactive oxygen species were early observed in samples undergoing Rpv12-mediated ETI and were paralleled and followed by the upregulation of genes belonging to ontology categories associated with salicylic acid signalling, signal transduction, WRKY transcription factors and synthesis of PR-1,PR-2, PR-5 pathogenesis-related proteins.

TL;DR: Genetic backgrounds donated by European winegrapes of the convarietas occidentalis provided on average higher levels of Rpv3 resistance than backgrounds of orientalis table grapes, which were stronger in highly native genetic backgrounds and tended to attenuate in late backcross generations.
