P48007 · PIST_ARATH

Function

function

Probable transcription factor involved in the genetic control of flower development. Is required for normal development of petals and stamens in the wild-type flower. Forms a heterodimer with APETALA3 that is required for autoregulation of both AP3 and PI genes. AP3/PI heterodimer interacts with APETALA1 or SEPALLATA3 to form a ternary complex that could be responsible for the regulation of the genes involved in the flower development. AP3/PI heterodimer activates the expression of NAP. AP3/PI prevents GATA22/GNL and GATA21/GNC expression (PubMed:18417639).

Miscellaneous

Mutations in PI cause transformation of petals into sepals and stamina into carpels.
