Weakly expressed in root and germinating seed, hardly in the anther-less-flower and not detected in leaf.MISCELLANEOUS:Defects in CP1 show overall delay of growth and development, and mature plants are dwarf. Panicle of CP1 mutant contains several flowers which remain unfertilized due to the abnormal development of the pollen.SIMILARITY:Belongs to the peptidase C1 family."
