Plant homeodomain (PHD)-finger proteins are a class of important zinc-finger transcription factors responsible for regulating transcription and the chromatin state and responsive to various stresses. The family genes have been reported in many plants, but there is little information about PHD-finger genes in moso bamboo. In this study, 60 PHD-finger genes (PePHD1-60) were identified in moso bamboo and classified into 11 subfamilies (A-K) based on phylogenetic analysis. Gene structure and conserved motif analysis showed that these genes contained different numbers of introns but had similar motif organizations within each subfamily. Multiple sequence alignment revealed that the PHD-finger proteins possessed conserved structural domain sequences. In addition, the family underwent purifying selection during evolution and experienced a large-scale duplication event around 7.69-15.4 million years ago. Most importantly, the expression profiles of young leaves (YL), mature leaves (L), roots (R), stems (S), shoots (Sh) and rhizomes (Rh) displayed that they might involve in the formation of these tissues. Based on promoter analysis of 16 putative stress-related genes, quantitative real-time PCR assays were performed using moso bamboo leaves and showed that these genes were differentially regulated under abscisic acid (ABA), drought, low temperature and NaCl treatments. Therefore, the results reveal that PePHD genes play crucial roles in organ formation and response to multiple environmental stress conditions of moso bamboo, which will make for further function analysis of PHD-finger genes in plants.
