Versatile physiological functions of the Nudix hydrolase family in berry development and stress response in grapevine

Nudix hydrolases are widely distributed across all classes of organisms and provide the potential capacity to hydrolyze a wide range organic pyrophosphates. Although involved in plant detoxification processes response abiotic biotic stresses, biological functions remain largely unclear grapevine. In present study, total 25 putative grapevine (VvNUDXs) were identified by bioinformatics analysis classified into eight subfamilies based their preferred substrates. Both tandem segmental duplications responsible for evolution expansion NUDX gene family To investigate regulatory roles VvNUDX genes during growth development, as well stresses grapevine, expression patterns revealed publicly available microarray data. The spatial temporal indicated that they might play important multiple developmental processes. Transcriptome qRT-PCR analyses showed ten specifically expressed berries, suggesting berry development. Expression phylogenetic demonstrated VvNUDX1 VvNUDX3 be terpenoid biosynthesis Furthermore, most active toward ADP-ribose/NADH different various such salinity drought, types treatments, Erysiphe necator, Bois Noir phytoplasma leaf-roll-associated virus-3 (GLRaV-3). These results associated with regulate disease immunity resistance pathways. information obtained here may good opportunities explore physiological development stress networks
