This provides evidence for a functional relationship between SALPs and WhiB-like proteins, which are both developmental proteins.

Interestingly, in the phylogenetic tree, SsgA proteins from strains that produce typical mycelial clumps but fail to produce submerged spores cluster together in a branch, designated NLSp figure 5 a.

However, our analysis of some 50 taxonomically diverse Streptomyces species show that more than half produced submerged spores in minimal medium, and many also in a rich medium. High conservation within specific actinomycete genera is also observed for the SsgB orthologues in the plant symbiont Frankia see electronic supplementary material, figure S6. SsgA is required for both solid- and liquid-culture sporulation of streptomycetes and is a key connection between these two types of cell division. The SsgB protein is part of the cell division machinery and recruits the cell division scaffold protein FtsZ to initiate sporulation-specific cell division in an SsgA-dependent manner [ 31 ]. It is also apparent that the aa sequence of SsgA is an accurate determinant for the ability of streptomycetes to produce submerged spores, dividing the phylogenetic tree of streptomycetes into liquid-culture sporulation and no liquid-culture sporulation branches. Classification of other actinomycetes High conservation within specific actinomycete genera is also observed for the SsgB orthologues in the plant symbiont Frankia see electronic supplementary material, figure S6.
