Gene Expression in the Early Floral Meristem.
The differential expression of genetic information facilitates the regulation of complex developmental pathways. Thus, to understand the control of morphogenesis, it is essential that the patterns of developmentally regulated gene activity and the basis for this regulation be determined. Perhaps the clearest illustration of the potential of this type of investigation comes from the analysis of ...
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 کاملFON2 SPARE1 Redundantly Regulates Floral Meristem Maintenance with FLORAL ORGAN NUMBER2 in Rice
CLAVATA signaling restricts stem cell identity in the shoot apical meristem (SAM) in Arabidopsis thaliana. In rice (Oryza sativa), FLORAL ORGAN NUMBER2 (FON2), closely related to CLV3, is involved as a signaling molecule in a similar pathway to negatively regulate stem cell proliferation in the floral meristem (FM). Here we show that the FON2 SPARE1 (FOS1) gene encoding a CLE protein functions ...
متن کاملUFO: an Arabidopsis gene involved in both floral meristem and floral organ development.
We describe the role of the UNUSUAL FLORAL ORGANS (UFO) gene in Arabidopsis floral development based on a genetic and molecular characterization of the phenotypes of nine ufo alleles. UFO is required for the proper identity of the floral meristem and acts in three different aspects of the process that distinguishes flowers from shoots. UFO is involved in establishing the whorled pattern of flor...
متن کاملUpdate on Floral Meristem Termination Time to Stop: Flower Meristem Termination
Flowers are the reproductive structure of angiosperms. They are composed of four distinct types of organs: sepals, petals, stamens, and carpels, which typically develop on four concentric rings, or whorls (Fig. 1A). In Arabidopsis (Arabidopsis thaliana), floral organ identity relies on the combinatorial action of four classes of flower-specific transcription factors, expressed in partially over...
