Annotation PubMed Id
floral phenotype of bellringer mutants is caused by derepression of AG, suggesting that BLR functions as a transcription repressor 15155890
AG activates biosynthesis of gibberellin, which has been proposed to promote the shift from meristem identity to differentiation 15634696
The data provides genetic evidence for the role of AP1 in these interactions by showing that the floral phenotype in the ap1 agl24 svp triple mutant is significantly enhanced. 16679456
AG and miR172 have distinct functions in flower development and that they largely act independently in the negative regulation of AP2. 17573799
The Arabidopsis homologs of trithorax (ATX1) and enhancer of zeste (CLF) interact to control the expression of the flower homeotic gene AGAMOUS. 17881378
These results indicate that stamen identity and differentiation control by AG is achieved by the regulation of different transcriptional cascades in different floral stages. 17981996
Transgenic Arabidopsis plants harboring two tissue-specific promoters, fAGIP and rAGIP in forward and reverse orientations, fAGIP::GUS or rAGIP::GUS displayed similar GUS expression specifically in carpel and stamen tissues and their primordial cells. 18256838
PERIANTHIA (PAN) plays a role in regulating stem cell fate by directly controlling AG expression and suggest that this activity is spatially restricted to the centermost region of the AG expression domain. 19395638
Upon enhanced central AG expression, the C-domain laterally expands necessitating tuning of the expression level of C-function genes in the wild type. 19554348
GIANT KILLER (AT2G35270) acts as a molecular node downstream of AGAMOUS, regulating patterning and differentiation of reproductive organs through chromatin organization 19956801
A model in which the decision whether stamens or petals develop is based on the balance between AP2 and AG activities, rather than the two being mutually exclusive. 20876650
Interaction between the PINOID/ABRUPTUS gene with the AGAMOUS gene: the negative regulator of stem cells in the meristem of Arabidopsis thaliana flower 21542343
AGAMOUS directly represses WUS expression by binding to the WUS locus and recruiting, directly or indirectly, PcG that methylates histone H3 Lys-27 at WUS. 22028461
in the delicately balanced regulatory network, NSN1 acts to repress AG and plays an additive role with AP2 in floral organ specification. 22357616
Data indicate that C function regulator AGAMOUS and the B function regulators APETALA3 and PISTILLATA control many developmental processes in conjunction, as well as independent activities. 23821642
In the floral meristem, the binding of AG to WUS is reduced in top1a-2, which results in reduced H3K27me3 levels at WUS and prolonged WUS expression, and consequently loss of floral determinacy. 25070639
ARF3 integrates the functions of AGAMOUS and APETALA2 in floral meristem determinacy. 25187180
The ULT1 and LFY pathways act separately in regulating identity and determinacy at the floral meristem. In particular, they independently induce AG expression in the centre of the flower to terminate meristem activity. 25288633
FLK and PEP physically interact with proteins involved in AG pre-mRNA processing to secure correct AG function in the floral meristem and flower 25658099
