Expression profiles of BnaHM genes in response to low and excess B. Cycle nodes represent genes and size of node represents power of the inter-relationship among nodes by degree value; colors of nodes represent log2FC value; red indicates up-regulated genes and blue indicates down-regulated genes; edges between nodes represent correlation. (a) Expression analysis of BnaHMs under low and normal B supply levels in roots. (b) Expression analysis of BnaHMs under excess and normal B supply levels in roots. (c) Expression analysis of BnaHMs under low and normal B supply levels in shoots. (d) Co-expression network analysis of differentially expressed BnaHMs under low and normal B supply levels in shoots. (e) Expression analysis of BnaHMs under excess and normal B supply levels in shoots. (f) Co-expression network analysis of differentially expressed BnaHMs under excess and normal B supply levels in shoots. BdR: low B-treated roots; BsR: control roots; BdS: low B-treated shoots; BsS: control shoots; BtR: excess B-treated roots; BtS: excess B-treated shoots; FC: fold-change
