Abstract

Calmodulin (CaM) and calmodulin-like (CML) proteins are two kinds of calcium (Ca2+)-sensing proteins that are involved in Ca2+-signaling processes. B. rapa and B. oleracea are two of three diploid Brassica species that have undergone recent additional Brassiceae-lineage-specific whole-genome triplication events. To elucidate the expansion, evolution, expression pattern and interaction network of these Ca2+ sensors in B. rapa and B. oleracea, we conducted a comparative syntenic study on a genome-wide level using Arabidopsis thaliana. In total, 80 and 79 CaM/CML genes were identified in B. rapa and B. oleracea, respectively. The CaM/CML genes have expanded throughout the whole genomes of B. rapa and B. oleracea by whole-genome and tandem duplication events. The CaMs/CMLs of B. rapa and B. oleracea can be classified into nine subgroups based on their A. thaliana orthologs. Expression data from various tissues revealed that a large portion of CaM/CML genes exhibited patterns of differential and tissue-specific expression. The expression levels among duplicated paralogs in different subgenomes demonstrated the expression divergence of these genes in B. rapa and B. oleracea. The differential expressions of duplicated CaM and CML gene...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
