| Research Abstract |
We aim to reveal the molecular function of SAP130 in plant morphogenesis. In Arabidopsis, the promoter activity of SAP130 was detected at a specific stage of pollen development. Coincidently, pollen from AtSAP130 RNAi plants showed low viability and developmental defects at this stage. We then analyzed plants partially complementing csn1 mutant with CSN1, to find that they also exhibited pollen developmental defect in similar manners. Here we hypothesize that CSN and SAP130 coordinately regulate mechanisms required for pollen development.
