ISOLATION OF CYSTEINE AND METHIONINE AUXOTROPHIC MUTANTS IN SINORHIZOBIUM MELILOTI

Author

Abstract
Random 'l‘n5 mutagenesis produced 2l cysteine/methionine and 13 methionine
au.'otrophic mutants of‘ Sinorliiznbimn me/1'/or/' strain Rmd20l. Linkage of Tn5 to
auxotroph indicated that each mutant had a single 'l‘n5 insertion. All auxotroph
showed spontaneous reversion to prototrophy and they resembled the parental strain
in production ofcell surface molecule and utilization of sugars and dicarboxylic acid.
