Isolation of two developmentally regulated genes involved in spore wall maturation in Saccharomyces cerevisiae.
During sporulation of Saccharomyces cerevisiae, the four haploid nuclei generated by meiosis are encapsulated within multilayered spore walls. Taking advantage of the natural fluorescence imparted to yeast spores by the presence of a dityrosine-containing macromolecule in the spore wall, we identified and cloned two genes, termed DIT1 and DIT2, which are required for spore wall maturation. Muta...
متن کاملDevelopmentally regulated cleavage of tRNAs in the bacterium Streptomyces coelicolor
The ability to sense and respond to environmental and physiological signals is critical for the survival of the soil-dwelling Gram-positive bacterium Streptomyces coelicolor. Nutrient deprivation triggers the onset of a complex morphological differentiation process that involves the raising of aerial hyphae and formation of spore chains, and coincides with the production of a diverse array of c...
متن کاملNepA is a structural cell wall protein involved in maintenance of spore dormancy in Streptomyces coelicolor.
Streptomycetes have a complex morphogenetic programme culminating in the formation of aerial hyphae that develop into chains of spores. After spore dispersal, environmental signals trigger dormant spores to germinate to establish a new colony. We here compared whole genome expression of a wild-type colony of Streptomyces coelicolor forming aerial hyphae and spores with that of the chp null muta...
