Varietal richness of grapevine (Vitis vinifera L.) from the Majes Valley, Peru: Identification, morphological characterization, ampelographic and genetic analysis

Inter- and Intra-Varietal Genetic Variability in Vitis vinifera L

Sugars and flowering in the grapevine (Vitis vinifera L.).

Sugars play an important role in grapevine flowering. This complex process from inflorescence initiation to fruit maturity takes two growing seasons. Currently, most of the available data concern the involvement of sugars as energy sources during the formation of reproductive structures from initiation of inflorescences during the summer of the first year, until flower opening during the follow...

Chloroplast genome diversity in Portuguese grapevine (Vitis vinifera L.) cultivars.

Grapevine chloroplast (cp) DNA diversity was analysed for the first time through amplification and digestion of fragments of the large single copy (LSC) region by polymerase chain reaction-restriction fragment length polymorphism methodology and also by amplification of three microsatellite loci, previously described as polymorphic in grapevine. Thirty-eight grapevine cultivars collected mainly...

Precision breeding of grapevine (Vitis vinifera L.) for improved traits.

This review provides an overview of recent technological advancements that enable precision breeding to genetically improve elite cultivars of grapevine (Vitis vinifera L.). Precision breeding, previously termed "cisgenic" or "intragenic" genetic improvement, necessitates a better understanding and use of genomic resources now becoming accessible. Although it is now a relatively simple task to ...

Oxidative stress homeostasis in grapevine (Vitis vinifera L.)

Plants can maintain growth and reproductive success by sensing changes in the environment and reacting through mechanisms at molecular, cellular, physiological, and developmental levels. Each stress condition prompts a unique response although some overlap between the reactions to abiotic stress (drought, heat, cold, salt or high light) and to biotic stress (pathogens) does occur. A common feat...
