Calmodulin Binding Transcription Activator (CAMTA) family is present in almost all
plants and in many animals. CAMTA are named so due to the presence of specific
calmodulin binding domain which is an important Ca2+ transducer. Multiple sequence
alignment and phylogenetic analysis of CAMTA proteins in Sorghum bicolor, Oryza
sativa, Zea mays, Glycine max and Arabidopsis thaliana showed highly conserved
sequence and evolutionary similarity. In Sorghum bicolor six CAMTA proteins were
identified to be located in nucleus. These proteins were named on the basis of their
location on the chromosomes. Alignment and phylogenetic tree clearly indicates close
similarity in monocot and dicot ancestry which appears on the same clade but diverged
from each other with time. Almost all CAMTA proteins share same domain
organizations. A highly conserved motif sequence in these species was identified which
might play some important functional roles. In order to understand structural and DNA
binding patterns of SbCAMTA proteins, 3-D models of proteins structure and their
domains revealed many important DNA binding residues playing their role in proteinprotein interaction and structural modification.. A further detailed study of the CAMTA
protein members in sorghum may explore their mode of interaction and exact function
in signaling mechanism under abiotic stresses.
