Fig. 6From: Genome-wide analysis of the bHLH gene family in Chinese jujube (Ziziphus jujuba Mill.) and wild jujubea Heat maps of the relative expression of ZjbHLH genes during flower development. FL1, bud emergence stage; FL2, inflorescence emergence stage; FL3, yellow bud stage; FL4, petal spread stage. 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 four ZjbHLHs by STRING databaseBack to article page
