The ERECTA receptor kinase regulates Arabidopsis shoot apical meristem size, phyllotaxy and floral meristem identity
In plants, the shoot apical meristem (SAM) serves as a reservoir of pluripotent stem cells from which all above ground organs originate. To sustain proper growth, the SAM must maintain homeostasis between the self-renewal of pluripotent stem cells and cell recruitment for lateral organ formation. At the core of the network that regulates this homeostasis in Arabidopsis are the WUSCHEL (WUS) tra...
متن کاملDown-regulation of TM29, a tomato SEPALLATA homolog, causes parthenocarpic fruit development and floral reversion.
We have characterized the tomato (Lycopersicon esculentum Mill.) MADS box gene TM29 that shared a high amino acid sequence homology to the Arabidopsis SEP1, 2, and 3 (SEPALLATA1, 2, and 3) genes. TM29 showed similar expression profiles to SEP1, with accumulation of mRNA in the primordia of all four whorls of floral organs. In addition, TM29 mRNA was detected in inflorescence and vegetative meri...
متن کاملGene 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 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 کاملRepression of Floral Meristem Fate Is Crucial in Shaping Tomato Inflorescence
Tomato is an important crop and hence there is a great interest in understanding the genetic basis of its flowering. Several genes have been identified by mutations and we constructed a set of novel double mutants to understand how these genes interact to shape the inflorescence. It was previously suggested that the branching of the tomato inflorescence depends on the gradual transition from in...
