Identification and characterization of Lateral Organ Boundaries Domain genes in mulberry, Morus notabilis

•We identified and characterized 31 LBD genes in Morus.•We analyzed the expression and phylogeny relationship with Arabidopsis of the Morus LBD genes for function prediction.•Morus LBD genes might implicate in variety of functions especially in lateral organ development and secondary metabolism.

Genes from the plant specific Lateral Organ Boundaries Domain (LBD) family encode transcriptional regulators that have a variety of functions in various physiological and developmental processes. In the present study, 31 LBD genes were identified in the mulberry genome. The genome features of all MnLBD genes and phylogenetic studies with Arabidopsis LBD protein sequences, accompanied by the expression analysis of each of the Morus LBD genes provide insights into the functional prediction of mulberry LBDs. The genome-wide surveys of the current mulberry genome have resulted in the identification of catalogs of MnLBD genes that may function in the development of leaf, root, and secondary metabolism in Morus sp.
