Calcium is an important second messenger that mediates plant adaptation to abiotic and biological stresses, and a variety of environmental stresses and pathogen invasion can cause rapid and transient changes in cell Ca2+ concentrations, playing an important
role in plant growth and development and stress regulation.
Calmodulin (CaM) and calmodulin-like (CML) proteins are the most important sensing proteins
involved in ca2+ signaling.
In this study, 15 TACAM and 113 TACML genes were identified using the wheat reference genome, of which the TaCAM2-D gene was significantly upregulated
under drought and salt stress.
Further analysis found that the TaCAM2-D gene was expressed in the nucleus, membrane and cytoplasm, and overexpression of the gene could significantly enhance the drought and salt tolerance of Arabidopsis thaliana; TaCAM2-D interacts
with the wheat mitose activating protein TamPK8.
Therefore, it is speculated that the stress response of TaCAMs may be regulated by the MAPKs signal transduction pathway
.
This study has important reference significance
for the analysis of the molecular mechanism of wheat stress resistance and the cultivation of new varieties of stress resistance.
