Functional analysis of tomato calmodulin gene family during fruit development and ripening.

ABSTRACT: Calmodulin is a ubiquitous calcium sensor to recognize the different developmental and/or stimulus-triggered calcium changes and regulate plant growth and development. However, the function of calmodulin remains elusive for fleshy fruit development. We performed expression studies of a family of six calmodulin genes (SlCaMs) in tomato fruit. All calmodulins showed a double peak expression pattern. The first flat peak appeared at 10-30 days after anthesis, but their expression rapidly declined at mature green and breaker. Then a sharp and even higher peak came at turning/pink stages. Among six calmodulins, SlCaM1 had the highest expression during fruit enlargement, whereas SlCaM2 was the major calmodulin during fruit ripening. However, SlCaMs showed different patterns in three ripening muta
