Genome‑wide identification of the SWEET gene family in grape (<i>Vitis vinifera</i> L.) and expression analysis of <i>VvSWEET14a</i> in response to water stress.

ABSTRACT: Sugars are considered primary metabolites that determine the flavor and quality of grape berries, also playing a crucial role in the plants to resist stress. Sugars Will Eventually be Exported Transporters (SWEETs) gene family has been previously reported to be involved in the growth and development of grape, while the changes in transcriptional levels under water stress remain unclear. In this study, sixteen grape SWEETs members were identified and annotated based on their homologous genes in Arabidopsis and tomato, they were classified into four clades (Clades I to IV) with VvSWEETs by phylogenetic analysis. The highly conserved motifs and gene structures of VvSWEETs indicate that they are closely evolutionary conservation. Chromosomal localization and
