Genome-wide identification and characterization of GATA family genes in wheat

Abstract

Background Transcription factors GATAs were a member of zinc finger protein, which could bind DNA regulatory regions to control expression of target genes, thus influencing plant growth and development either in normal condition or environmental stresses. Recently, GATA genes have been found and functionally characterized in a number of plant species. However, little information of GATA genes were annotated in wheat. Results In the current study, 79 GATA genes were identified in wheat, which were unevenly located on 21 chromosomes. According to the analysis of phylogenetic tree and functional domain structures, TaGATAs were classified into four subfamilies (I, II, III, and IV), consist of 35, 21, 12, and 11 genes, respectively. Meanwhile, the amino acids of 79 TaGATAs exhibited apparent difference in four subfamilies according to GATA domains comparison, gene structures and conserved motif analysis. We then analyze the gene duplication and synteny between the genomes of wheat and Arabidopsis, rice and barley, which provided insights into evolutionary characteristics. In addition, expression patterns of TaGATAs were analyzed, and they showed obvious difference in diverse tissues and abiotic stresses. Conclusion In general, these results provide useful information for future TaGATA gene function analysis, and it helps to better understand molecular breeding and stress response in wheat.

Genome-Wide Identification, Evolution, and Expression Pattern Analysis of the GATA Gene Family in Tartary Buckwheat (Fagopyrum tataricum)

“…GATA TFs are ubiquitous in plants and are closely related to plant growth and development, quality, and yield. They regulate the germination and dormancy of plant seeds [ 12 ], the formation of organs and morphogenesis [ 13 ], the synthesis and accumulation of chlorophyll pigments [ 14 ], responses to environmental stress [ 15 ], and other biological processes. Phytochrome-interacting factors (PIF) can regulate the expression of GNC (GATA21)- and GNL (GATA22)-related transcription factors that regulate seed germination [ 16 ].…”

Genetic and Epigenetic Responses of Autochthonous Grapevine Cultivars from the ‘Epirus’ Region of Greece upon Consecutive Drought Stress

“…Genes belonging to the GATA-gene family are involved in the activation of a series of genes related to the regulation of the response to changes in the photoperiod and additionally regulate the accumulation of chlorophyll [22]. Nevertheless, the regulatory function of these genes is affected by environmental changes, thus their expression indirectly changes under abiotic stresses, as was reported in recent studies [78,79]. In the present study, the expression of the VvGATA26-like gene showed no remarkable change between the stressed plants and the control plants, and only a slight up-regulation was observed in the stressed self-rooted plants of the Dichali cultivar.…”

Genome‐wide characterization and expression analysis of GATA transcription factors under combination of light wavelengths and drought stress in potato

“…While the exon intron structure of the subgroups did not display consistent gene structure patterns (especially regarding the intron number), the number of exons (2) was highly consistent and conserved compared to the variable intron number (1-10). Different gene structure patterns have been associated with the diverse functional roles of GATA TFs, as observed in other plant species (Feng et al, 2022;Peng et al, 2021). Understanding the tissue-specific expression and functional roles of GATA TFs can provide insights into their regulatory mechanisms in potato and other plants.…”
