LEAFY 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… Expand
Distinct roles of CONSTANS target genes in reproductive development of Arabidopsis.
In plants, flowering is triggered by endogenous and environmental signals. CONSTANS (CO) promotes flowering of Arabidopsis in response to day length. Four early target genes of CO were identified… Expand
Activation tagging in Arabidopsis.
Activation tagging using T-DNA vectors that contain multimerized transcriptional enhancers from the cauliflower mosaic virus (CaMV) 35S gene has been applied to Arabidopsis plants. New… Expand
B and C floral organ identity functions require SEPALLATA MADS-box genes
Abnormal flowers have been recognized for thousands of years, but only in the past decade have the mysteries of flower development begun to unfold. Among these mysteries is the differentiation of… Expand
Molecular characterization of the Arabidopsis floral homeotic gene APETALA1
THE first step in flower development is the transition of an inflorescence meristem into a floral meristem. Each floral meristem differentiates into a flower consisting of four organ types that… Expand
The protein encoded by the Arabidopsis homeotic gene agamous resembles transcription factors

Mutations in the homeotic gene agamous of the plant Arabidopsis cause the transformation of the floral sex organs. Cloning and sequence analysis of agamous suggest that it encodes a protein with a… Expand
Assessing the redundancy of MADS-box genes during carpel and ovule development
Carpels are essential for sexual plant reproduction because they house the ovules and subsequently develop into fruits that protect, nourish and ultimately disperse the seeds. The AGAMOUS (AG) gene… Expand
Redundant regulation of meristem identity and plant architecture by FRUITFULL, APETALA1 and CAULIFLOWER.
The transition from vegetative to reproductive phases during Arabidopsis development is the result of a complex interaction of environmental and endogenous factors. One of the key regulators of this… Expand
SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis

The fruit, which mediates the maturation and dispersal of seeds, is a complex structure unique to flowering plants. Seed dispersal in plants such as Arabidopsis occurs by a process called fruit… Expand
The SEP4 Gene of Arabidopsis thaliana Functions in Floral Organ and Meristem Identity
