Identification of a gene encoding a thioredoxin-like product necessary for cytochrome c biosynthesis and symbiotic nitrogen fixation in Rhizobium leguminosarum

Vargas Macías, Carmen Wu, Guanghui Davies, Andrea E.

A Tn5-induced mutant of Rhizobium leguminosarum bv. viciae could not form nitrogen-fixing nodules on pea or vetch because of a lesion in electron transport to oxygen. The mutant lacked spectroscopically detectable cytochromes c and aa3. No proteins containing c-type cytochromes could be identified in the mutant by heme staining of proteins...

Characterization of the cycHJKL genes involved in cytochrome c biogenesis and symbiotic nitrogen fixation in rhizobium leguminosarum

Delgado, María Jesús Yeoman, Kay H. Wu, Guanghui

Mutants of Rhizobium leguminosarum bv. viciae unable to respire via the cytochrome aa3 pathway were identified by the inability to oxidize N,N*-dimethyl-p-phenylenediamine. Two mutants which were complemented by cosmid pIJ1942 from an R. leguminosarum clone bank were identified. Although pea nodules induced by these mutants contained many...
