Disease relevance of rosR

One mutant that contained an insertion in a gene with similarity to exsH of Sinorhizobium meliloti did not nodulate the plant host Phaseolus vulgaris without rosR [1].

High impact information on rosR

To understand how RosR affects these phenotypes, we mutagenized a rosR mutant derivative of R. etli strain CE3 with a mini-Tn5 that contains a promoterless gusA gene at one end, which acts as a transcriptional reporter [1].
DNA sequence analysis indicated that this 1.2-kb fragment contained a single open reading frame that we designated rosR [2].
