TL;DR
expression analyses based on RNA-seq data showed that HaGPAT genes exhibited variable expression profiles under different tissues, contributing to a better understanding of the structural features, evolutionary relationships, and expression profiles of the HaGPAT gene family.
Abstract
Glycerol-3-phosphate acyltransferase (GPAT) are enzymes involved in glycerolipid biosynthesis and play a key role in plant growth, development, and abiotic stress responses. However, a comprehensive genome-wide and in silico analysis of the GPAT gene family in sunflower (Helianthus annuus L.) has not been performed to date. In this study, the GPAT gene family in the sunflower genome was characterized using bioinformatics approaches. A total of 23 HaGPAT genes were identified; their chromosomal distributions, phylogenetic relationships, gene structures, conserved motifs, protein properties, subcellular localizations, cis-regulatory elements, miRNA targets, protein-protein interaction networks, three-dimensional protein structures, synteny relationships, duplication events, Ka/Ks ratios, and expression profiles based on RNA-seq data were analyzed. Expression analyses based on RNA-seq data showed that HaGPAT genes exhibited variable expression profiles under different tissues. These findings contribute to a better understanding of the structural features, evolutionary relationships, and expression profiles of the HaGPAT gene family, and constitute a valuable genomic resource for future functional studies.
