(Submitter supplied) The filamentous bacterium Streptomyces coelicolor differentiates by forming specialized, spore-bearing aerial hyphae that grow into the air. Using microarrays, we identified genes that are down-regulated in a mutant unable to erect aerial hyphae. Through this route, we identified a previously unknown layer of aerial mycelium surface proteins (the "chaplins"). The chaplins share a hydrophobic domain of ~40 residues (the "chaplin domain"), and all have a secretion signal. more...

(Submitter supplied) The developmental life cycle of Streptomyces species includes aerial hyphae formation and spore maturation, two distinct developmental processes that are controlled, respectively, by two families of developmental regulatory genes, bld and whi. In this study, we show that the response regulator MtrA (SCO3013) is critical for normal development of aerial hyphae in S. coelicolor and related species. ΔmtrA, a deletion mutant of the response regulator gene mtrA, exhibited the bald phenotype typical of bld mutants defective in aerial mycelium formation, with formation either much delayed or absent depending on the culture medium. more...

(Submitter supplied) A. niger undergoes dramatic changes during asexual development. We tried to identify the differences in RNA expression levels that are important for this development. We used micro-arrays to determine which genes were up- or down-regulated in the aerial structures, the part of the colony that is formed during asexual development.
