Whole Genome Identification and Analysis of Potato CDPKs Family
Calcium is an important second messenger in eukaryotic signal transduction.In plants,intracellular Ca2+ levels are affected by a variety of factors,including hormone levels,light signals,physical damage,abiotic stress and pathogen infection.In plants,CDPKs represent a new class of Ca2+ sensors with both protein kinase and calmodulin domains.CDPKs can bind directly to calcium,and so that their kinase activity is independent of calmodulin protein.A total genome analysis of the potato CDPKs family revealed that there are 21 CDPKs in the potato genome,all of which have the key domain of CDPKs.The CDPKs genes of potato locate mainly on chromosome 1 and chromosome 10.CDPKs on 1st and 10th chromosomes of the genetic relationship is very close,may be derived from gene amplification.Our research will help to accumulate the genetic resources of potatoes and promote the process of potato breeding.
