Grapevine is grown under extensive fungicide use, mainly due to two diseases native to North America that were introduced to Europe in the nineteenth century, downy mildew and powdery mildew.
The R2R3-MYB transcription factors VviMYB14 and VviMYB15 are established master regulators of the stilbene biosynthetic pathway in grapevine, directly modulating stilbene synthase (STS) genes.
Grapevine (Vitis vinifera) is amongst the world’s most cultivated fruit crops, and of global and economic significance.
The present study aimed to identify genomic regions associated with leaf resistance to grapevine phylloxera (Daktulosphaira vitifoliae).
Black rot, caused by Phyllosticta ampelicida (Guignardia bidwellii), is a serious fungal disease in viticulture. Incidences increased in recent years due to reduced pesticide treatments, neglected phytosanitary measurements, and effects of climate change.
Despite significant progress in grapevine research, conducting functional genetic studies at the berry level remains challenging due to the species’ physiological and developmental limitations, including its perennial growth habit, large plant size, and long juvenile phase.
Plant microRNAs are small regulatory RNAs that control gene expression and play key roles in plant development and stress adaptation.
Gene regulation in grapevine emerges from interconnected above- and below-ground responses to the environment.
Hemizygous genes, are genes present on only one copy of the genome (only one allele) and should not be confused with homozygous genes.
Understanding how grafts form has fascinated scientists for over a century, and numerous transcription factors (TFs) involved in wound healing, callus formation, and graft development have been identified in model plants.
Berry juice color plays a critical role in determining grape and wine quality, influencing consumer preferences and market appeal.
RNA-seq is a standard approach for studying gene expression in grapevine, yet downstream bioinformatics remains a bottleneck.
Berry texture and seed size are major components of grapevine fruit quality, influencing both consumer perception and technological performance; however, the genetic bases of these traits remain incompletely understood.
The grapevine genome harbors considerable levels of structural variation that represent an important source of functional variation and could result in high levels of cis-regulatory variation.
To diversify production, vinegrowers select somatic variants in grape color that arise spontaneously during the propagation of cultivars.
