To investigate the genetic loci to regulate the development of petal shape, screening of the mutation affecting lateral petal development was conducted in a model plant of legume, Lotus japonicus. Two independent mutants, kew2 and kew3 with the similar phenotype were obtained, whose shape of lateral petal is altered and resembles the one of ventral petal in the wild type. Genetic analysis showed that kew3 was caused by the same single recessive locus and allelic to the one of kew1, a formal identified mutant in the locus KEW1. KEW1 has been shown to be an ortholog of K in pea, but whose mutation at the molecular level is unsolved yet. Furthermore, genetic analyses of kew2 indicate that there are other genetic factors which could interact with kew and involve in the lateral petal development. Analysis of these mutations and cloning the corresponding loci will shield light on the underlying molecular mechanism in the control of floral asymmetry and facilitate our understanding on the evolution of the zygomorphic development.
