Nitrogen fixation in transposon mutants from Bradyrhizobium japonicum USDA 110 impaired in nitrate reductase.

Journal of plant physiology - 1 Apr 2003

Camacho María, Burgos Araceli, Chamber-Pérez Manuel A

Abstract excerpt

Tn5 transposon mutagenesis was carried out in Bradyrhizobium japonicum strain USDA 110 to produce defective mutants. From over one thousand clones expressing low levels of nitrate reductase activity as free-living bacteria, approximately five percent had significantly different ratios of nodulation, N2 fixation or nitrate reductase activity compared to the wild strain when determined in bacteroids from soybean...
