Role of Glutathione in the Morphogenesis of the Bacterial Spore Coat [PDF]
Journal of Bacteriology, 1973 There is a marked increase in the half-cystine content of bacterial spores, especially the coat layers at the time of formation of the outer coat. When a cysteine auxotroph of Bacillus cereus T is grown on limiting cysteine, the spores contain the normal content of half-cystine, suggesting an alternate source ...

A screen for spore wall permeability mutants identifies a secreted protease required for proper spore wall assembly. [PDF]
PLoS ONE, 2009 The ascospores of Saccharomyces cerevisiae are surrounded by a complex wall that protects the spores from environmental stresses. The outermost layer of the spore wall is composed of a polymer that contains the cross-linked amino acid dityrosine.

Advanced Science, EarlyView.This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.
