Fig. 7From: Basic helix-loop-helix (bHLH) gene family in rye (Secale cereale L.): genome-wide identification, phylogeny, evolutionary expansion and expression analysesExpression patterns of 22 S. cereale bHLH genes in several plant organs. (A) Expression patterns of 22 S. cereale bHLH genes in the roots, stems, leaves, flowers and grains were examined via qRT-PCR. Error bars were obtained from three measurements. Lowercase letters above the bars indicate significant differences (α = 0.05, The least significant difference test [LSD]) among the treatments. (B) Expression patterns of 22 S. cereale bHLH genes were examined during different grain development stages: 7 DPA (early filling stage), 14 DPA (mid filling stage), 21 DPA (early ripening stage), 28 DPA (mid ripening stage), and 35 DPA (full ripening stage). The statistical method is consistent with Fig. 7ABack to article page
