Biology:Agamous
From HandWiki
AGAMOUS (AG) is a homeotic gene and MADS-box transcription factor protein present in Arabidopsis thaliana. The TAIR AGI number is AT4G18960.
The identity of a floral organ is determined by particular combinations of the protein products of homeotic genes. These proteins act within regions of undifferentiated cells known as the floral meristem and give the cells a developmental fate. The presence of the AGAMOUS homeotic gene product in Arabidopsis results in the cessation of all meristem activity and cells procede to facilitate the development of stamens and carpels. In the absence of the AG protein, stamens and carpels do not develop and meristem activity continues, resulting in flowers consisting of many whorls of sepals and petals.[1]
