Genome-wide identification of MADS-box family genes in moso bamboo (Phyllostachys edulis) and a functional analysis of PeMADS5 in flowering.


ABSTRACT: MADS-box genes encode a large family of transcription factors that play significant roles in plant growth and development. Bamboo is an important non-timber forest product worldwide, but previous studies on the moso bamboo (Phyllostachys edulis) MADS-box gene family were not accurate nor sufficiently detailed.Here, a complete genome-wide identification and characterization of the MADS-box genes in moso bamboo was conducted. There was an unusual lack of type-I MADS-box genes in the bamboo genome database ( http://202.127.18.221/bamboo/index.php ), and some of the PeMADS sequences are fragmented and/or inaccurate. We performed several bioinformatics techniques to obtain more precise sequences using transcriptome assembly. In total, 42 MADS-box genes, including six new type-I MADS-box genes, were identified in bamboo, and their structures, phylogenetic relationships, predicted conserved motifs and promoter cis-elements were systematically investigated. An expression analysis of the bamboo MADS-box genes in floral organs and leaves revealed that several key members are involved in bamboo inflorescence development, like their orthologous genes in Oryza. The ectopic overexpression of one MADS-box gene, PeMADS5, in Arabidopsis triggered an earlier flowering time and the development of an aberrant flower phenotype, suggesting that PeMADS5 acts as a floral activator and is involved in bamboo flowering.We produced the most comprehensive information on MADS-box genes in moso bamboo. Additionally, a critical PeMADS gene (PeMADS5) responsible for the transition from vegetative to reproductive growth was identified and shown to be related to bamboo floral development.
