Repression of AGAMOUS by BELLRINGER in floral and inflorescence meristems.
A common aspect of gene regulation in all developmental systems is the sustained repression of key regulatory genes in inappropriate spatial or temporal domains. To understand the mechanism of transcriptional repression of the floral homeotic gene AGAMOUS (AG), we identified two mutations in the BELLRINGER (BLR) gene based on a striking floral phenotype, in which homeotic transformations from s...
متن کاملControl of reproductive floral organ identity specification in Arabidopsis by the C function regulator AGAMOUS.
The floral organ identity factor AGAMOUS (AG) is a key regulator of Arabidopsis thaliana flower development, where it is involved in the formation of the reproductive floral organs as well as in the control of meristem determinacy. To obtain insights into how AG specifies organ fate, we determined the genes and processes acting downstream of this C function regulator during early flower develop...
متن کاملLEAFY controls floral meristem identity in Arabidopsis
The first step in flower development is the generation of a floral meristem by the inflorescence meristem. We have analyzed how this process is affected by mutant alleles of the Arabidopsis gene LEAFY. We show that LEAFY interacts with another floral control gene, APETALA1, to promote the transition from inflorescence to floral meristem. We have cloned the LEAFY gene, and, consistent with the m...
متن کاملFONf, an Arabidopsis Gene That Terminates Floral Meristem Activity and Controls Flower Organ Number
A novel gene that regulates floral meristem activity and controls floral organ number was identified in Arabidopsis and is designated FONl (for FLORAL QRGAN NUMBERl). The fonl mutants exhibit normal vegetative development and produce normal inflorescence meristems and immature flowers before stage 6. fonl flowers become visibly different from wild-type flowers at stage 6, when the third-whorl s...
متن کاملFON1, an Arabidopsis gene that terminates floral meristem activity and controls flower organ number.
A novel gene that regulates floral meristem activity and controls floral organ number was identified in Arabidopsis and is designated FON1 (for FLORAL ORGAN NUMBER1). The fon1 mutants exhibit normal vegetative development and produce normal inflorescence meristems and immature flowers before stage 6. fon1 flowers become visibly different from wild-type flowers at stage 6, when the third-whorl s...
