In recent years, molecular biomarkers have emerged as important tools in modern agriculture, facilitating the monitoring of plant health and providing objective assessments of resistance and susceptibility to environmental factors. Within the realm of grapevines (Vitis vinifera L.), genomic biomarkers hold promise owing to their ability to integrate multifaceted, context-dependent information.
In this context, telomere length emerges as a promising, rapid, and cost-effective genomic biomarker, as observed in other species such as mammals and other plants. Telomeres, repetitive DNA sequences situated at chromosome ends, play a central role in safeguarding genetic material from damage and have been widely used in processes related to health, aging, and stress in mammalian models.
Quantitative real-time PCR (qPCR) enables precise quantification of telomere length relative to an internal reference gene specific to grapevines, ensuring stable measurements across diverse environmental conditions. Implementation of this novel protocol will facilitate the evaluation of telomere length dynamics in grapevines under varying conditions, thereby providing a valuable tool for assessing the vine's health status.
This contribution presents the first results on the Aglianico vine subjected to different levels of water stress (irrigated and non-irrigated) under the same soil in an area of southern Italy devoted to the production of high-quality wines (Taurasi DOCG area) in the Tenuta Donna Elvira winery (Montemiletto—AV).
The results were be achieved within the BeViteLo project.
