Gene
TSO1, At3g22780, MWI23.15
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Probable floral-specific cell division component, required for proper organ formation in flowers. Regulates the floral meristem cell division and the inflorescence meristem organization. Plays a role in development of both male and female reproductive tissues.4 Publications
