Superman (gene)

From Wikipedia, the free encyclopedia

SUPERMAN is a plant gene in Arabidopsis thaliana that plays a role in controlling the boundary between stamen and carpel development in a flower.[1] It is named for the comic book character Superman, and the related genes kryptonite (gene) and clark kent were named accordingly (although the latter turns out to just be another form of superman).[2] It encodes a transcription factor (specifically a C2H2 type zinc finger protein).[3] Homologous genes are known in the petunia[4] and snapdragon[5], which are also involved in flower development, although in both cases there are important differences from the functioning in Arabidopsis. Superman is expressed early on in flower development, in the stamen whorl adjacent to the carpel whorl.[4] It interacts with the other genes of the ABC model of flower development in a variety of ways.[4]
