Tissue and Spatio-temporal expression patterns and correlation analysis of 12 Setaria italica GATA genes. a Tissue-specific expression pattern of GATA genes at the mid-grain filling stage. Expression profiles of 12 S. italica GATA genes in young leaves, mature leaves, roots, stems, peels, and seed organs. b Correlation analysis of tissue-specific expression of GATA genes. c Expression patterns of 12 S. italica GATA genes during fruit development. qRT-PCR was used to detect the expression of GATA genes in the peel and fruit before, during, and after grain filling. d Correlation analysis of GATA gene-specific expression during the grain-filling process. In the bar chart, the error bars were obtained from three measurements. Lowercase letters above the horizontal line indicate significant differences between treatments (α = 0.05, LSD). In the graph of the correlation analysis, a positive number indicates a positive correlation, whereas a negative number means a negative correlation. Red numbers indicate a significant correlation at the 0.05 level
