Agamous - Wikipedia
Agamous (AG) is a homeotic gene and MADS-box transcription factor from Arabidopsis thaliana. The TAIR AGI number is AT4G18960. The identity of a floral organ is determined by particular combinations of homeotic genes, these genes derive from a group of undifferentiated cells known as the floral meristem. The presence of the homeotic gene in ...

One factor, many systems: the floral homeotic protein AGAMOUS …
2021年6月1日 · In Arabidopsis, the MADS-box transcription factor AGAMOUS (AG) plays a central role in regulating reproductive organ identity and meristem determinacy during flower development. During the vegetative phase, AG transcription is repressed by Polycomb complexes and intronic noncoding RNA.
Mutations in the agamous (AG) gene result in the overall phenotype of a flower within a flower and the absence of stamens and carpels. The six stamens have been replaced in ag mutant flowers by...
The homeotic protein AGAMOUS controls microsporogenesis by …
2004年7月15日 · The Arabidopsis homeotic gene AGAMOUS (AG) is necessary for the specification of reproductive organs (stamens and carpels) during the early steps of flower development 1, 2, 3. AG encodes a...
Transcriptional program controlled by the floral homeotic gene AGAMOUS …
2005年2月1日 · In Arabidopsis, the homeotic gene AGAMOUS (AG) terminates meristem activity and promotes development of stamens and carpels. To understand the program of gene expression activated by AG, we followed genome-wide …
AGAMOUS regulates various target genes via cell cycle-coupled …
2023年8月2日 · The MADS domain transcription factor AGAMOUS (AG) regulates floral meristem termination by preventing maintenance of the histone modification lysine 27 of histone H3 (H3K27me3) along the KNUCKLES (KNU) coding sequence.
Regulatory Elements of the Floral Homeotic Gene AGAMOUS …
In Arabidopsis thaliana, cis-regulatory sequences of the floral homeotic gene AGAMOUS (AG) are located in the second intron. This 3-kb intron contains binding sites for two direct activators of AG, LEAFY (LFY) and WUSCHEL (WUS), along with other putative regulatory elements.
MADS reloaded: evolution of the AGAMOUS subfamily genes
2013年10月25日 · AGAMOUS subfamily proteins are encoded by MADS-box family genes. They have been shown to play key roles in the determination of reproductive floral organs such as stamens, carpels and ovules. However...
AGAMOUS terminates floral stem cell maintenance in Arabidopsis …
AGAMOUS (AG), a MADS domain transcription factor essential for the termination of floral stem cell fate, has long been thought to repress the stem cell maintenance gene WUSCHEL (WUS) indirectly. Here, we uncover a role of Polycomb Group (PcG) genes in the temporally precise repression of WUS expression and termination of floral stem cell fate.
