Morphological and gene expression characterization of maf-1, a floral chili pepper mutant caused by a nonsense mutation in CaLFY.

ABSTRACT: Chili peppers are important as vegetables and ornamental crops, because of the variety of fruit shapes and colors. Understanding of flower and fruit development in Capsicum is limited compared with closely related Solanaceae crops such as tomato. This study reports a novel malformed fruit mutant named malformed fruit-1 (maf-1), which was isolated from an ethyl methanesulfonate-induced mutant population of chili pepper. maf-1 exhibited homeotic changes in the floral bud, which were characterized by conversion of petals and stamens into sepal-like and carpel-like organs, respectively. In addition, the indeterminate formation of carpel-like tissue was observed. Genetic analysis demonstrated that the causative gene in maf-1 is a nonsense mutation in CaLFY<
