Metabolic biomarker-based phenotyping unveils quantitative effects of plant resistance and pathogen aggressiveness in the grapevine (Vitis spp.) - downy mildew (Plasmopara viticola) pathosystem Open
Grapevine resistance to downy mildew has been primarily associated with major “Resistance to Plasmopara viticola ” ( Rpv ) loci, which are extensively used in breeding programs. Resistant varieties represent an effective solution to mitiga…

Minimising sunburn necrosis on <i>Vitis vinifera</i> L. ‘Riesling’ grapes by defoliation, photo- and thermal protection Open
Sunburn on grapes has emerged as an economic concern in recent decades. The phenomenon can be attributed to climatic changes, characterised by elevated air temperatures and intense solar radiation, leading to increased crop failures as wel…

Fungicide-Saving Potential and Economic Advantages of Fungus-Resistant Grapevine Cultivars Open
The high susceptibility of European grapevine cultivars to downy mildew (DM) and powdery mildew (PM) causes the intensive use of fungicides. Fungus-resistant cultivars (FRCs) with different resistance (R) loci have been bred and could play…

Direct regulation of shikimate, early phenylpropanoid, and stilbenoid pathways by Subgroup 2 <span>R2R3‐MYBs</span> in grapevine Open
SUMMARY The stilbenoid pathway is responsible for the production of resveratrol in grapevine ( Vitis vinifera L.). A few transcription factors (TFs) have been identified as regulators of this pathway but the extent of this control has not …

Gene duplication and transposition of mobile elements drive evolution of the Rpv3 resistance locus in grapevine Open
Summary A wild grape haplotype (Rpv3‐1) confers resistance to Plasmopara viticola . We mapped the causal factor for resistance to an interval containing a TIR‐NB‐LRR ( TNL ) gene pair that originated 1.6–2.6 million years ago by a tandem s…

Impact of pulsed <span>UV‐B</span> stress exposure on plant performance: How recovery periods stimulate secondary metabolism while reducing adaptive growth attenuation Open
Upon continuous stress exposure, plants display attenuated metabolic stress responses due to regulatory feedback loops. Here, we have tested the hypothesis that pulsed stress exposure with intervening recovery periods should affect these f…

Combinatorial Regulation of Stilbene Synthase Genes by WRKY and MYB Transcription Factors in Grapevine (Vitis vinifera L.) Open
Stilbene synthase (STS) is the key enzyme leading to the biosynthesis of resveratrol. Recently we reported two R2R3-MYB transcription factor (TF) genes that regulate the stilbene biosynthetic pathway in grapevine: VviMYB14 and VviMYB15. Th…

Transcriptome-Wide Identification of Novel UV-B- and Light Modulated Flavonol Pathway Genes Controlled by VviMYBF1 Open
Flavonols constitute a group of flavonoids with important photoprotective roles in plants. In addition, flavonol content and composition greatly influences fruit quality. We previously demonstrated that the grapevine R2R3-MYB transcription…
