Early flower development in Arabidopsis.
The early development of the flower of Arabidopsis thaliana is described from initiation until the opening of the bud. The morphogenesis, growth rate, and surface structure of floral organs wereExpand
Radial Patterning of Arabidopsis Shoots by Class III HD-ZIP and KANADI Genes
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
Role of PHABULOSA and PHAVOLUTA in determining radial patterning in shoots
This work implicates the Arabidopsis PHABULOSA and PHAVOLUTA genes in the perception of radial positional information in the leaf primordium and implicates this domain as a central regulator of protein function and the PHB and PHV proteins as receptors for an adaxializing signal. Expand
Criteria for Annotation of Plant MicroRNAs
The specific criteria required for the annotation of plant miRNAs are updated, including experimental and computational data, as well as refinements to standard nomenclature. Expand
Control of flower development in Arabidopsis thaliana by APETALA1 and interacting genes
The results suggest that the products of APETALA1 and another gene, LEAFY, are required to ensure that primordia arising on the flanks of the inflorescence apex adopt a floral fate, as opposed to becoming an inflorescence shoot. Expand
Members of the YABBY gene family specify abaxial cell fate in Arabidopsis.
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
The protein encoded by the Arabidopsis homeotic gene agamous resembles transcription factors
The agamous gene probably encodes a transcription factor that regulates genes determining stamen and carpel development in wild-type flowers. Expand
SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis
It is shown that the closely related SHATTERPROOF (SHP1) and SHP2 ) MADS-box genes are required for fruit dehiscence in Arabidopsis, and that further analysis of the molecular events underlying fruit deHiscence may allow genetic manipulation of pod shatter in crop plants. Expand
Genetic interactions among floral homeotic genes of Arabidopsis.
The phenotypes of multiple mutant lines indicate that the wild-type products of the AGAMOUS and APETALA2 genes interact antagonistically, and a model is proposed that suggests that the products of these homeotic genes are each active in fields occupying two adjacent whorls. Expand
Genes directing flower development in Arabidopsis.
It seems that the wild-type alleles of these four genes allow cells to determine their place in the developing flower and thus to differentiate appropriately and is proposed that these genes may be involved in setting up or responding to concentric, overlapping fields within the flower primordium.
