Finally, based on transmission electron microscopy observations, we propose that FtsL and DivIC are involved in coordinating symmetrical annular ingrowth of the invaginating septum. Alternatively, another division protein may partially compensate for the loss of both FtsL and DivIC on minimal medium or sucrose-free R2YE. PICTs will not provide the fish recommended for good nutrition of growing Pacific. Furthermore, double mutant strains deleted for both ftsL and divIC are viable and have medium-dependent phenotypes similar to that of the single mutant strains, suggesting that functions performed by FtsL and DivIC are not absolutely required for septation during growth and sporulation. Analyses reported here demonstrate that coastal fisheries in 16 of the 22.
Thus, osmolarity appears to affect the severity of the division defect. h or irrad iated with 25 mJ/cm 2 (15 s) broadband 305-12nm UVB (Daavlin Bryan, OH, USA) without test materials and incubated for an additional 18 h. Surprisingly, this phenotype was largely suppressed when strains were grown on minimal medium or sucrose-free R2YE, where division sites in many aerial hyphae had finished constricting and chains of spores were evident. When mutant strains were grown on a conventional rich medium (R2YE, containing high sucrose), inactivation of either ftsL or divIC resulted in the formation of aerial hyphae with partially constricted division sites but no clear separation of prespore compartments. We show by deletion-insertion mutations that ftsL and divIC are dispensable for growth and viability in S. Thermogenic effects of dihydrocodeine in the rat Rothwell, Nancy J.
We have characterized homologues of the bacterial cell division genes ftsL and divIC in the gram-positive mycelial bacterium Streptomyces coelicolor A3(2).
