Relationship between signaling and metabolic pathways of grapevines under temperature and light stresses—a review

Depending on plant genotype–environment interactions, cell signal transduction, and thereby gene expression, disruptive or promotive effects on grapevine physiology, metabolism, and, consequently, fruit quality and yield may occur. This review article aims to evaluate the effects of temperature and light stress on grapevine signaling and metabolic pathways to provide insights into breeding/engineering strategies for designing grapevines with improved quality, yield and tolerance. The modifications of signaling and metabolic pathways are discussed to assist geneticists with designing tolerant grape cultivars with high capacity of producing bioactive compounds and, thereby health-promoting effects in grapevines and humans.
