The outer plastid envelope protein OEP16-1 was previously identified as an amino acid-selective channel protein and translocation pore for NADPH:protochlorophyllide oxidoreductase A (PORA). Reverse genetic approaches used to dissect these mutually not exclusive functions of OEP16-1 in planta have led to descriptions of different phenotypes resulting from the presence of several mutant lines in the SALK_024018 seed stock. In addition to the T-DNA insertion in the AtOEP16-1 gene, lines were purified that contain two additional T-DNA insertions and as yet unidentified point mutations. In a first attempt to resolve the genetic basis of four different lines in the SALK_024018 seed stock, we used genetic transformation with the OEP16-1 cDNA and segregation analyses after crossing out presumed point mutations. We show that AtOEP16-1 is involved in PORA precursor import and by virtue of this activity confers photoprotection onto etiolated seedlings during greening. | |
