Radial Patterning of Arabidopsis Shoots by Class III HD-ZIP and KANADI Genes
TLDR
Based on complementary vascular and leaf phenotypes of class III HD-ZIP and KANADI mutants, it is proposed that a common genetic program dependent upon miRNAs governs adaxial-abaxial patterning of leaves and radial patterned stems in the angiosperm shoot. Expand
Members of the YABBY gene family specify abaxial cell fate in Arabidopsis.
TLDR
Observations indicate that members of the YABBY gene family are responsible for the specification of abaxial cell fate in lateral organs of Arabidopsis, and ectopic expression studies suggest that ubiquitous abaxials cell fate and maintenance of a functional apical meristem are incompatible. Expand
Establishment of polarity in lateral organs of plants
TLDR
The phenotypes of KANADI loss- and gain-of-function alleles suggest that fine regulation of these genes is at the core of polarity establishment, and they are likely to be targets of the PHB-mediated meristem-born signaling that patterns lateral organ primordia. Expand
Asymmetric leaf development and blade expansion in Arabidopsis are mediated by KANADI and YABBY activities
TLDR
It is proposed that the initial asymmetric leaf development is regulated primarily by mutual antagonism between KANADI and PHB-like genes, which is translated into polar YABBY expression, which contributes both to abaxial cell fate and to abxial/adaxial juxtaposition-mediated lamina expansion. Expand
Establishment of polarity in angiosperm lateral organs.
TLDR
The complex relationships between and within various members of these plant-specific gene families (class III HD-ZIPs, YABBYs and KANADIs) might account for a substantial part of the morphological variation in lateral organs of seed plants. Expand
Distinct Mechanisms Promote Polarity Establishment in Carpels of Arabidopsis
TLDR
It is argued that the unique genetic interactions do not reflect a molecular redundancy, rather, CRABS CLAW regulates transcription spatially, whereas GYMNOS regulates downstream targets temporally to ensure proper differentiation of the carpels. Expand
Recruitment of CRABS CLAW to promote nectary development within the eudicot clade
TLDR
It is proposed that diverse nectaries in core eudicot species share conserved CRC gene regulation, and that derived nectary positions in eudicots have altered regulation of CRC. Expand
Activation of CRABS CLAW in the Nectaries and Carpels of Arabidopsisw⃞
TLDR
It is proposed that in wild-type flowers, a combination of floral homeotic gene activities, specifically the B class genes APETALA3 and PISTILLATA and the C class gene AGAMOUS act redundantly with each other and in combination with SEPALLATA genes to activate CRC in the nectaries and carpels. Expand
Molecular genetics of gynoecium development in Arabidopsis.
TLDR
The genes identified can be arranged in a functional hierarchy: specification of carpel identity, patterning of the carpel primordium and directing the differentiation of the specialized tissues of thecarpel. Expand
Root apical organization inArabidopsis thaliana 1. Root cap and protoderm
TLDR
The coordinated division sequence of the dermatogen/calyptrogen and the increase in the number of protoderm cell files are both features of post-embryonic development within the primary root meristem. Expand
