The WUSCHEL-related homeobox (WOX) gene PRESSED FLOWER1 (PRS1) performs a conserved function during lateral organ development in Arabidopsis (Arabidopsis thaliana). Expressed in the periphery of the shoot meristem, PRS1 recruits founder cells that form lateral domains of vegetative and floral organs. Null mutations in PRS1 cause the deletion of lateral stipules from leaves and of lateral sepals and stamens from flowers. Although PRS1 expression is described in the L1 layer, PRS1 recruits… Expand
WOX4 Promotes Procambial Development1[W][OA]
TLDR
The cumulative data suggest that the conserved WOX4 function is to promote differentiation and/or maintenance of the vascular procambium, the initial cells of the developing vasculature. Expand
WUSCHEL-related Homeobox genes in Populus tomentosa: diversified expression patterns and a functional similarity in adventitious root formation
TLDR
This is the first attempt towards a systematical analysis of the function of WOXs in P. tomentosa and revealed that the expression patterns of some PtoWOXs were different to their Arabidopsis counterparts, indicating a functional similarity of these four Woxs in AR regeneration. Expand
LOOSE FLOWER, a WUSCHEL-like Homeobox gene, is required for lateral fusion of floral organs in Medicago truncatula.
TLDR
The data suggest that the STF/Wox1 and LFL/WOX3 genes of M. truncatula employ a similar mechanism of action in organizing cell proliferation for lateral outgrowth but may have evolved different cis elements to acquire distinct functions. Expand
Evolutionarily conserved repressive activity of WOX proteins mediates leaf blade outgrowth and floral organ development in plants
TLDR
It is found that fusion of either the WUS-box or an exogenous repressor domain to WOX7 or to members of intermediate and ancient WOX clades results in a gain-of-function ability to complement lam1 blade outgrowth. Expand
Control of dicot leaf blade expansion by a WOX gene, STF
TLDR
Morphological analysis of mutants and STF expression patterns suggest that STF regulates blade outgrowth mainly by controlling cell division in the margins of leaf primordium. Expand
The WUSCHEL-related homeobox1 gene of cucumber regulates reproductive organ development
TLDR
Data suggest that CsWOX1 may regulate early reproductive organ development and be involved in sporogenesis via the CsSPL-mediated pathway and/or modulate auxin signaling in cucumber. Expand
Analyses of WOX4 transgenics provide further evidence for the evolution of the WOX gene family during the regulation of diverse stem cell functions
TLDR
The identification of super-compound leaf phenotypes induced by overexpression of the SlWOX4 ortholog in tomato suggests a functional link between vascular patterning and leaf complexity. Expand

TLDR
It is shown that knocking out SlLAM1 via CRISPR/Cas9-mediated genome editing led to narrow leaves, and reduced number of secondary leaflets, and Overexpression of tomato SlL AM1 could rescue the defect of tobacco lam1 mutant. Expand
The WUSCHELa (PtoWUSa) is Involved in Developmental Plasticity of Adventitious Root in Poplar
TLDR
Results suggest that PtoWUSa could be involved in AR development in Populus tomentosa WUSCHELa through regulating the polar auxin transport in ARs. Expand
The WUSCHEL‐RELATED HOMEOBOX 3 gene PaWOX3 regulates lateral organ formation in Norway spruce
TLDR
The data suggest that the WOX3 function in margin outgrowth in lateral organs is conserved among the seed plants, whereas its function in root elongation may be unique to gymnosperms. Expand

Requirement of Homeobox Gene STIMPY/WOX9 for Arabidopsis Meristem Growth and Maintenance
TLDR
STIMPY (STIP) is characterized, a homeobox gene required for the growth of the vegetative SAM, in part by positively regulating WUS expression, which suggests that STIP identifies a new genetic pathway integrating developmental signals with cell-cycle control. Expand
A homeobox gene, PRESSED FLOWER, regulates lateral axis-dependent development of Arabidopsis flowers.
TLDR
Double-mutant analyses showed that the PRS gene functions independently of the determinations of both floral organ identity and floral meristem size, suggesting that thePRS gene is involved in the molecular mechanism of lateral axis-dependent development of lateral organs in Arabidopsis. Expand
NARROW SHEATH1 functions from two meristematic foci during founder-cell recruitment in maize leaf development.
TLDR
Analyses of mutant, sectored plants demonstrate that NS1 function is required in L2-derived tissue layers for development of the narrow sheath leaf domain and support the model for NS function during founder-cell recruitment in the maize meristem. Expand
The PRETTY FEW SEEDS2 gene encodes an Arabidopsis homeodomain protein that regulates ovule development
TLDR
In the plants that made ovules, ectopic PFS2 expression blocked megaspore mother cell differentiation and often impeded polarized growth of the outer integument. Expand
The WUSCHEL gene is required for shoot and floral meristem integrity in Arabidopsis.
TLDR
The results suggest that the WUS gene is specifically required for central meristem identity of shoot and floral meristems to maintain their structural and functional integrity. Expand
WUSCHEL controls meristem function by direct regulation of cytokinin-inducible response regulators
TLDR
A mechanistic link between the CLV/WUS network and hormonal control is shown and the observation that a mutant ARR7 allele, which mimics the active, phosphorylated form, causes the formation of aberrant shoot apical meristems is observed. Expand
The maize duplicate genes narrow sheath1 and narrow sheath2 encode a conserved homeobox gene function in a lateral domain of shoot apical meristems
TLDR
Previously undiscovered phenotypes in the pressed flower mutant support a model whereby the morphology of eudicot leaves and monocot grass leaves has evolved via the differential elaboration of upper versus lower leaf zones. Expand
RAGGED SEEDLING2 is required for expression of KANADI2 and REVOLUTA homologues in the maize shoot apex
TLDR
In situ hybridization and qRT‐PCR analyses reveal that rgd2‐R mutants show reduced accumulation of adaxial and abaxial molecular markers in the maize shoot apex, contributing to a revised model whereby RGD2 is required for normal accumulation of leaf patterning transcripts in the developing shoot.

Regulation of cell proliferation patterns by homeotic genes during Arabidopsis floral development.

It is shown that AGAMOUS is required to maintain the layered structure of the meristem prior to organ initiation, as well as having a non-autonomous role in the regulation of the layer contributions to the petals. Expand

TLDR
A role is proposed for WOX5 in the root apical meristem as a negative trigger of IAA homeostatic mechanisms allowing the maintenance of a restricted area of auxin maximum, which is required for a correct root-formation pattern. Expand
