a Heat maps of the relative expression of ZjbHLH genes during fruit ripening in ‘Lizao’ and ‘Yazao’. Y, young fruit; EWM, early white mature fruit; WM, white mature fruit; HR, half-red fruit; FR, full red fruit. Scaled log2 expression values based on qRT-PCR data are shown from blue to red, indicating low to high expression. b The protein-protein interaction analysis of two ZjbHLHs by STRING database
