Source Description
UniprotDEVELOPMENTAL STAGE: In embryo sac, detected as early as the one-nucleus stage. In older embryo sacs, highest expression in antipodal cells. {ECO:0000269|PubMed:17209126}.
UniprotTISSUE SPECIFICITY: Expressed in leaves, leaf primordia, immature ears, immature tassels, whole ovules, silk and husk leaves. Found on the adaxial side of organs. {ECO:0000269|PubMed:17209126}.
Functional Description ? help Back to Top
Source Description
UniProtPromotes the switch from proliferation to differentiation in the embryo sac. Negative regulator of cell proliferation in the adaxial side of leaves. Regulates the formation of a symmetric lamina and the establishment of venation. Interacts directly with RS2 (rough sheath 2) to repress some knox homeobox genes. {ECO:0000269|PubMed:17209126}.
