Calmodulin is encoded by a 650-nucleotide mRNA in higher plants. This messenger was identified in barley and pea by a combination of in vitro translation and blot hybridization experiments using anti-sense RNA produced from an eel calmodulin cDNA probe. In all plant tissues tested, calmodulin mRNA represents between 0.01 and 0.1% of the total translatable mRNA population. Calmodulin mRNA levels are three- to fourfold higher in the meristematic zone of the first leaf of barley. At all other stages of leaf cell differentiation, calmodulin mRNA levels are nearly identical. During light-induced development in barley leaves, the relative proportion of translatable calmodulin mRNA declines about twofold. Cytoplasmic mRNAs that may encode calmodulin-like proteins were also detected. The levels of several of these putative Ca(2+)-binding protein mRNAs are modulated during the course of light-induced barley leaf cell development.
