Genome-wide identification and characterization of Calcium-Dependent Protein Kinase (CDPK) gene family in autotetraploid cultivated alfalfa (Medicago sativa subsp. sativa) and expression analysis under abiotic stresses.

ABSTRACT:

Background

Calcium-dependent protein kinases (CDPKs), play multiple roles in plant development, growth and response to bio- or abiotic stresses. Calmodulin-like domains typically contain four EF-hand motifs for Ca²⁺ binding. The CDPK gene family can be divided into four subgroups in Arabidopsis, and it has been identified in many plants, such as rice, tomato, but has not been investigated in alfalfa (Medicago sativa subsp. sativa) yet.

Results

In our study, 38 non-redundant MsCDPK genes were identified from the "XinJiangDaYe" alfalfa genome. They can be divided into four subgroups which is the same as in Arabidopsis and Medicago truncatula, and there were 15, 12,10 and 1 in CDPK I, II, III and IV, respectively. RNA-seq analysis revealed tissue-specificity of 38 MsCDPK genes.
