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 کاملRate of meristem maturation determines inflorescence architecture in tomato.
Flower production and crop yields are highly influenced by the architectures of inflorescences. In the compound inflorescences of tomato and related nightshades (Solanaceae), new lateral inflorescence branches develop on the flanks of older branches that have terminated in flowers through a program of plant growth known as "sympodial." Variability in the number and organization of sympodial bra...
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 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 کاملGrass meristems I: shoot apical meristem maintenance, axillary meristem determinacy and the floral transition.
The vegetative and reproductive shoot architectures displayed by members of the grass family are critical to reproductive success, and thus agronomic yield. Variation in shoot architecture is explained by the maintenance, activity and determinacy of meristems, pools of pluripotent stem cells responsible for post-embryonic plant growth. This review summarizes recent progress in understanding the...
