摘要

Plant calcium-dependent protein kinases (CDPKs) play important roles in diverse physiological processes by regulating the downstream components of calcium signaling. To date, only a few species of the plant CDPK gene family have been functionaly identiifed. In addition, there has been no systematic analysis of the CDPK family in cotton. Here, 41 putative cotton CDPK (GrCDPK) genes were identiifedvia bioinformatics analysis of the entire genome ofGossypium raimondi and were classiifed into four groups based on evolutionary relatedness. Gene structure analysis indicated that most of these GrCDPK genes share a similar intron-exon structure (7 or 8 exons), strongly supporting their close evolutionary relationships. Chromosomal distributions and phylogenetics analysis showed that 13 pairs of GrCDPK genes arosevia segmental duplication events. Furthermore, using microarray data of upland cotton (G. hirsutumL.), comparative proifles analysis of these GhCDPKs indicated that some of the encoding genes might be involved in the responses to multiple abiotic stresses and play important regulatory roles during cotton ifber development. This study is the ifrst genome-wide analysis of the CDPK family in cotton, and it wil provide valuable information for the further functional characterization of cotton CDPK genes.
