Gene regulation in wild and cultivated Vitis species during deacclimation and budbreak
Ontology highlight
ABSTRACT: Dormant grapevine buds from 4 genotypes were collected over a variable time series after being exposed to growth room temperatures. Buds were collected from the field during winter and assessed for the loss of cold hardiness (deacclimation) in tandem with analysis of gene expression changes. DEGs are examined for various enriched pathways. Wild grapevines deacclimate faster than cultivated grapevines and the entire gene regulation cascade was also faster in wild grapevines. No keystone genes were identified that could explaint he faster phenotype, suggesting all the regulatory pathways are tuned faster in wild grapes.
