Genome-wide identification, phylogenetic and expression pattern analysis of GATA gene family in .

INTRODUCTION

The transcription factor GATA plays a pivotal role in plant growth, physical and metabolic functions, and responses to changes in the environment. After the completion of the genome, investigations into its GATA gene family were not pursued.

METHODS

Our research team identified the GATA gene's bioinformatics techniques, analyzed its structural characteristics and evolutionary trajectory, and investigated its expression patterns among various subfamilies.

RESULTS

In the genome,20 are divided into four unique subgroups distributed over 7 chromosomes. Collinearity analysis showed 7 pairs of segmental duplications and 2 pairs of tandem repeats. The duplication of these fragments is vital for the development of the ChGATA family. The evolutionary connection between and the GATA gene family is more evident than with . Moreover, the promoter region of the ChGATA gene family contained cis-acting elements linked to stress, hormones, and plant growth. The transcriptome heatmap showed that the expression of the was specific under alkali stress, and in the same subpopulation would also show different expression patterns. qPCR analysis showed that most of the screened first decreased and then increased with time. In addition, the dual luciferase assay and protein interaction prediction showed that could activate the expression of the differentially expressed gene in response to alkali stress, and ChGATA14 was at the core of the protein interaction network and had a strong interaction with ChGATA2 and ChGATA16.

DISCUSSION

This study laid a theoretical and scientific foundation for further studies on the biological function of .
