Genome-Wide Identification of the Gene Family and Its Diverse Roles in Chlorophyll Biosynthesis.

GATA transcription factors have been demonstrated to play key regulatory roles in plant growth, development, and hormonal response. However, the knowledge concerning the evolution of genes in and their trans-regulatory interaction is indistinct. Phylogenetic analysis and study of conserved motifs, exon structures, and expression patterns resolved the evolutionary relationships of these GATA proteins. Phylogenetic analysis showed that are broadly distributed in four subfamilies. -element analysis of promoters revealed that genes respond to light and are influenced by multiple hormones and abiotic stresses. Transcriptome analysis revealed distinct temporal and spatial expression patterns of genes in various tissues of S.T.Blake, which was confirmed by real-time quantitative PCR (RT-qPCR). Further research revealed that and were localized in the nucleus, and directly binds to the -element of the promoter, implying its potential roles in the regulation of chlorophyll synthesis. This comprehensive study provides new insights into the evolution of s and could help to improve the photosynthetic assimilation and vegetative growth of at the genetic level.
