Summary
Twenty nine uvr mutations of Bacillus subtilis Marburg have been classified into two groups by mutual transformation crosses. One, uvrA, contained 20 mutations and involved uvrAl which had been isolated by Reiter and Strauss (1965) and linked to the hisA gene by Hoch and Anagnostopoulos (1970). Another group, uvrB, contained 9 mutations and the linkage relationship has been established as argA-polA-uvrB-leu-pheA. Both of them seemed to govern the incision reaction upon DNA containing pyrimidine dimers or spore photoproducts. It thus seems that in B. subtilis, as in Escherichia coli, the process of excision repair is controlled by the products of two or more genes not closely linked in the chromosome.
