Abstract
Golden2-like (G2-like) transcription factor, a member of the GARP superfamily of MYB transcription factors, plays an important role in regulating chloroplast development. In this study, genome-wide identification of G2-like genes in wheat was carried out by bioinformatics methods, and their physicochemical properties, subcellular localization, cis-acting elements of promoters, and response patterns to abiotic stresses and hormones were analyzed. A total of 87 G2-like genes were identified from wheat, which distributed in evenly on 21 chromosomes in wheat. Phylogenetic analysis showed that these genes were divided into 14 subfamilies, and fragment replication was the main reason for the expansion of this gene family. The prediction of protein secondary structure revealed that α helix and random curl were the main amino acid sequences of G2-like gene in wheat. Promoter cis-acting elements showed that there were seven cis-acting elements (P-box, SpI, LTR, ABRE, MBS, TGA-Element, and AE-box) in 2-kb region upstream of the promoter. Among them, Ta3AG2-Like19 contained the most cis-regulatory element binding sites with a total of 18 binding sites. The qRT-PCR revealed. that the relative expression levels of Ta3AG2-like19, Ta3AG2-Like20, Ta4AG2-Like29, and Ta6AG2-Like52 were significantly up-regulated under PEG and salt stresses, and induced by GA, IAA, and ABA hormones. These genes may mediate the response of wheat plant to various abiotic stresses.
