Colonial differentiation in Streptomyces coelicolor depends on translation of a specific codon within the adpA gene.
We identified adpA as an araC-like regulatory gene needed for colonial morphogenesis in Streptomyces coelicolor and showed that its activity depended on a unique TTA triplet corresponding to the leucyl-tRNA gene (bldA). These findings partially explained the dependence of aerial mycelium formation on a rare tRNA that is postulated to have developmental control functions.
