Abstract Calmodulin (CaM) proteins play a key role in signal transduction under various stresses. In the present study,
the effects of a sugarcane ScCaM gene (NCBI accession number: GQ246454) on drought and salt stress tolerance in
transgenic Arabidopsis thaliana and Escherichia coli cells were evaluated. The results demonstrated a significant
negative role of ScCaM in the drought and salt stress tolerance of transgenic lines of A. thaliana, as indicated by the
phenotypes. In addition, the expression of AtP5CS and AtRD29A, two genes tightly related to stress resistance, was
significantly lower in the overexpression lines than in the wild type. The growth… More >
