Abstract

Cosmids carrying a rec gene of the Erwinia chrysanthemi strain B374 were identified in a genomic library constructed by Reverchon et al. (1985). One of them was mutagenized with transposon Tn1 and the rec::Tn1 mutation was introduced into the B374 chromosome, providing the first rec-less E. chrysanthemi strain. The pectinolytic and cellulolytic activities were unaffected by the rec mutation.
