Genome-wide identification and expression analysis of the JAZ gene family in turnip


ABSTRACT: JAZ is a plant-specific protein family involved in the regulation of plant development, abiotic stresses, and responses to phytohormone treatments. In this study, we carried out a bioinformatics analysis of JAZ genes in turnip by determining the phylogenetic relationship, chromosomal location, gene structure and expression profiles analysis under stresses. The 36 JAZ genes were identified and classified into four subfamilies (ZML, JAZ, PPD and TIFY). The JAZ genes were located on 10 chromosomes. Two gene pairs were involved in tandem duplication events. We identified 44 collinear JAZ gene pairs in the turnip genome. Analysis of the Ka/Ks ratios indicated that the paralogs of the BrrJAZ family principally underwent purifying selection. Expression analysis suggested JAZ genes may be involved in the formation of turnip tuberous root, and they also participated in the response to ABA, SA, MeJA, salt stress and low-temperature stress. The results of this study provided valuable information for further exploration of the JAZ gene family in turnip.
