摘要
Calcium-dependent protein kinases(CDPKs or CPKs) play important roles in various physiological processes of plants,including growth and development,stress responses and hormone signaling. Although the CDPK gene family has been characterized in several model plants,little is known about this gene family in Hevea brasiliensis(the Para rubber tree). Here,we characterize the entire H. brasiliensis CDPK and CDPK-related kinase(CRK) gene families comprising 30 CDPK genes(HbCPK1 to 30) and 9 CRK genes(Hb CRK1 to 9). Structure and phylogeny analyses of these CDPK and CRK genes demonstrate evolutionary conservation in these gene families across H. brasiliensis and other plant species. The expression of HbCPK and Hb CRK genes was investigated via Solexa sequencing in a range of experimental conditions(different tissues,phases of leaf development,ethylene treatment,and various abiotic stresses). The results suggest that HbCPK and Hb CRK genes are important components in growth,development,and stress responses of H. brasiliensis. Parallel studies on the CDPK and CRK gene families were also extended to five other plant species(Arabidopsis thaliana,Oryza sativa,Populus trichocarpa,Manihot esculenta and Ricicus communis). The CDPK and CRK genes from different plant species that exhibit similar expression patterns tend to cluster together,suggesting a co-evolution of gene structure and expression behavior in higher plants. The results serve as a foundation to further functional studies of these gene families in H. brasiliensis as well as in the whole plant kingdom.
