| Abstract: | ARhodobacter sphaeroides gene (pps) inducestrans suppression of bacteriochlorophyll (Bch) and carotenoid (Crt) levels in bothR. sphaeroides andR. capsulatus. It also induces suppression of Crt levels in aParacoccus denitrificans strain carrying the Crt genes ofR. sphaeroides. The gene is located approximately 11 kilobases fromcrtA in the photosynthetic gene cluster. Crt suppression bypps is quantitatively different from that caused by an absence of mature Bch. |
