Abstract

Background: Calcium ions, which are the most versatile secondary messenger found in plants, are involved in regulation of diverse arrays of plant growth and development, as well as biotic and abiotic stress responses. The calcineurin B-like genes are one of the most important genes that act as calcium sensors. Results: In the present study, we identified calcineurin B-like gene family members from 38 different plant species and assigned each a unique nomenclature. Sequence analysis showed that the CBL proteins contain three calcium binding EF-hand domains that held several conserved Asp and Glu amino acid residues. The third EF-hand of the CBL genes was found to posses the D/E-x-D calcium binding sensor motif. Phylogenetic analysis showed that the CBL genes fall into six different groups. Additionally, except group B CBLs, all the CBL protein was found to contain N-terminal palmitoylation and myristoylation sites. An evolutionary study showed that CBL genes are evolved from a common ancestor and subsequently diverged during the course of evolution of land plants. Tajima’s neutrality test showed that CBL genes are highly polymorphic and evolved via decreasing population size due to balanced selection. Differential expression analysis with cold and heat stress led to differential modulation of OsCBL genes.Conclusions: The basic architecture of plant CBL genes is conserved throughout the plant kingdom. Evolutionary analysis showed that CBL genes evolved from a common ancestor of lower eukaryotic plant lineage and led to broadening of the calcium signaling events in higher eukaryotic organisms.
