title: CaM and CML emergence in the green lineage.
abstract: Calmodulin (CaM) is a well-studied calcium sensor that is ubiquitous in all eukaryotes and contributes to signaling during developmental processes and adaptation to environmental stimuli. Among eukaryotes, plants have a remarkable variety of CaM-like proteins (CMLs). The expansion of genomic data sets offers the opportunity to explore CaM and CML evolution among the green lineage from algae to land plants. Database analysis indicates that a striking diversity of CaM and CMLs evolved in angiosperms during terrestrial colonization and reveals the emergence of new CML classes throughout the green lineage that correlate with the acquisition of novel biological traits. Here, we speculate that expansion of the CML family was driven by selective pressures to process environmental signals efficiently as plants adapted to land environments.
