Signaling of cell fate decisions by CLAVATA3 in Arabidopsis shoot meristems.
TLDR
Genetic analysis indicates that CLV1, which encodes a receptor kinase, acts with CLV3 to control the balance between meristem cell proliferation and differentiation in Arabidopsis thaliana plants with loss-of-function mutations in the CLAVATA genes.
The fasciated ear2 gene encodes a leucine-rich repeat receptor-like protein that regulates shoot meristem proliferation in maize.
TLDR
Findings provide evidence that the CLAVATA pathway for regulation of meristem size is functionally conserved throughout the angiosperms.
The ERECTA receptor kinase regulates Arabidopsis shoot apical meristem size, phyllotaxy and floral meristem identity
TLDR
The ERECTA (ER) pathway is identified as a second receptor kinase signaling pathway that regulates WUS expression, and therefore shoot apical and floral meristem size, independently of the CLV pathway and it is demonstrated that reduction in class III HD-ZIP and ER function together leads to a significant increase in W US expression, resulting in extremely enlarged shoot meristems and a switch from spiral to whorled vegetative phyllotaxy.
ULTRAPETALA1 encodes a SAND domain putative transcriptional regulator that controls shoot and floral meristem activity in Arabidopsis
TLDR
It is shown that ULT1 negatively regulates the size of the WUSCHEL (WUS)-expressing organizing center in inflorescence meristems, and is cloned and found that it encodes a small protein containing a B-box-like motif and a SAND domain, a DNA-binding motif previously reported only in animal transcription factors.
A possible role for kinase-associated protein phosphatase in the Arabidopsis CLAVATA1 signaling pathway.
TLDR
This work shows that KAPP, a gene encoding a kinase-associated protein phosphatase, is expressed in apical and young floral meristems, along with CLV1, and presents a model where KAPP functions as a negative regulator of the CLAVATA1 signal transduction pathway.
Shoot and floral meristem maintenance in arabidopsis.
TLDR
Recent results demonstrating that the fate of stem cells in Arabidopsis shoot and floral meristems is controlled by overlapping spatial and temporal signaling systems are summarized.
Regulation of meristem size by cytokinin signaling.
TLDR
The current understanding of the molecular mechanisms underlying CK actions in regulating meristematic tissue proliferation is reviewed.
Comparative Mapping Combined With Map-Based Cloning of the Brassica juncea Genome Reveals a Candidate Gene for Multilocular Rapeseed

The Arabidopsis ERECTA gene encodes a putative receptor protein kinase with extracellular leucine-rich repeats.
TLDR
The cloned ER gene encodes a putative receptor protein kinases, and the results suggest that cell-cell communication mediated by a receptor kinase has an important role in plant morphogenesis.
CLAVATA3 IS A SPECIFIC REGULATOR OF SHOOT AND FLORAL MERISTEM DEVELOPMENT AFFECTING THE SAME PROCESSES AS CLAVATA1
TLDR
It is proposed that CLV1 and CLV3 are required to promote the differentiation of cells at the shoot and floral meristem.
CLAVATA1, a regulator of meristem and flower development in Arabidopsis.
TLDR
Double mutant combinations of clavata1 with apetala1 and leafy indicate CLAVATA1 plays a role in establishing and maintaining floralMeristem identity, in addition to its role in controlling meristem size.
LEAFY controls floral meristem identity in Arabidopsis
Expression of floricaula in single cell layers of periclinal chimeras activates downstream homeotic genes in all layers of floral meristems.
TLDR
It is shown that the flowering sectors on plants mutant for floricaula (flo), a meristem identity gene in Antirrhinum majus, are periclinal chimeras expressing flo in either the L1, L2 or L3 cell layer, showing that flo acts inductively to promote gene transcription.
Role of SUPERMAN in maintaining Arabidopsis floral whorl boundaries
TLDR
It is shown that the putative SUPERMAN protein contains one zinc-finger and a region resembling a basic leucine zipper motif, suggesting a function in transcriptional regulation.
Expression of maize KNOTTED1 related homeobox genes in the shoot apical meristem predicts patterns of morphogenesis in the vegetative shoot
TLDR
The expression patterns of a family of homeobox genes in maize and their relationship to organogenic domains in the vegetative shoot apical meristem are described, showing distinct expression patterns that together predict the site of leaf initiation and the basal limit of the Vegetative ‘phytomer’ or segmentation unit of the shoot.
Characterisation of three shoot apical meristem mutants of Arabidopsis thaliana
TLDR
The genetic and phenotypic characterisation of recessive mutations at three loci of Arabidopsis thaliana in which meristem structure and function are disrupted is described.
A dominant mutation in the maize homeobox gene, Knotted-1, causes its ectopic expression in leaf cells with altered fates.
TLDR
Kn1 functions in its wild-type context as a regulator of cell determination and apparently alters the fates of leaf cells in which it is ectopically expressed from an early stage of leaf development.
