Fruit-developmental regulation of bell pepper knolle gene (cakn) expression

A cDNA, cakn, orthologous to the Arabidopsis KN gene, which is involved in vesicle fusion during cell plate formation, was isolated from bell pepper f ruit, cakn seems to be monogenic and its expression mainly transcriptionall y regulated. During fruit development, transcript and protein levels increa se significantly in the early stages in which numerous cell divisions occur . but in the stages corresponding to fruit growth by cell enlargement, wher eas the messengers are undetectable, proteins are still faintly present, su ggesting a different stability rate for the two types of macromolecules.
