The gene FLORAL ORGAN NUMBER1 regulates floral meristem size in rice and encodes a leucine-rich repeat receptor kinase orthologous to Arabidopsis CLAVATA1.

Abstract excerpt

The regulation of floral organ number is closely associated with floral meristem size. Mutations in the gene FLORAL ORGAN NUMBER1 (FON1) cause enlargement of the floral meristem in Oryza sativa (rice), resulting in an increase in the number of all floral organs. Ectopic floral organs develop in the whorl of each organ and/or in the additional whorls that form. Inner floral organs are more severely affected than...
