These were classified, along with previously described mutants, into seven groups according to map location. The mutations in 26 GerA mutants mapped between cysB and thr; detailed mapping of two of these has located them very close to citG. These mutants were deficient in germination in alanine, but responded to the germinative combination of asparagine, glucose, fructose and KCl. One GerB mutant mapped on the origin-proximal side of hisA; it was normal in germination in alanine, but deficient in germination in a mixture of asparagine, glucose, fructose and KCl. Two GerC mutants were linked to lys, but were separable from a temperature-sensitive growth deficiency mapping between lys and trp. The GerC mutants had a similar germination phenotype to the GerA mutants. Three GerD mutants did not germinate in either of the above germinants or in Penassay Broth. They were located on the side of ery distal to cysA. The GerE mutant, which did not germinate in any of the three germinants, was located very close to citF and possessed an altered spore coat. The two GerF mutants were defective in germination in all three germinants and mapped on the origin proximal-side of hisA, but much closer to his than did the GerB mutant. A phosphoglycerate kinase-negative mutant altered in germination mapped between cysB and hisA (GerG). These mutants have established a minimum of seven locations important to germination, and will be useful in the development and appraisal of theories of spore germination.", }
