The cis-acting elements on putative promoters of PbrLBD genes. (a) The distribution of cis-acting elements on putative promoters of PbrLBD genes. A phylogenetic tree of PbrLBD protein family was constructed by Mega-X using the Neighbor–Joining (NJ) method and 1000 bootstraps. The blue branches of phylogenetic tree indicate LBD genes in class I; the red branches of phylogenetic tree indicate LBD genes in class II. (b) The number of cis-acting elements on putative promoters of PbrLBD genes. A total of eleven cis-acting elements were investigated in our study, including: (I) Meristem expression, (II) light responsive element, (III) Low-temperature responsiveness, (VI) ABA responsiveness, (V) MYB binding site involved in drought-inducibility, (VI) ABA responsiveness, (VII) Salicylic acid responsiveness, (VII) MYB binding site involved in flavonoid biosynthetic genes regulation, (IX) IAA responsiveness, (X) MeJA-responsiveness, (XI) GA responsive element
