Abstract

Cyclin-dependent kinase (CDK), the pivotal controller of cell cycle progression, is involved in stress resistance and plant growth. Moso bamboo (Phyllostachys edulis) with surprisingly rapid growth depends on continuous cell division, but the CDK gene family information is still lacking. Here, we performed the systematic identification and analysis of the CDK genes in moso bamboo. 40 PeCDK genes were identified and divided into eight subgroups via phylogeny. The same subgroup possessed extremely conserved sequences and similar gene structure. In addition, evolutionary analysis suggested that the PeCDK gene family may have experienced extensive duplication events primarily 6.85–13.71 million years ago (MYA), with segmental duplication dominating. Furthermore, the multiple promoter cis-elements determined in PeCDK genes indicated their potential functions. The expression patterns revealed that most PeCDK genes participated in responses to drought, salt, ABA and SA signals, cell wall synthesis, organ developmental processes and callus growth. The insights gained provide beneficial reference for clarifying the functions of PeCDKs as well as exploring the growth mechanism in bamboo.
