Correlation analysis between expression of the PPR genes in kernels and kernel-related traits. The horizontal coordinate represents the correlation coefficient, and the vertical coordinate represents the -log10 value (P-value). a, b, c show the correlation with HKW (hundred kernel weight), KW (kernel width) and KN (kernel number), respectively
