Genetic and functional characterization of a novel meta‐pathway for degradation of naringenin in Herbaspirillum seropedicae SmR1NARA Subscribed
Summary In this study, a random mutant library of Herbaspirillum seropedicae SmR1 was constructed by Tn 5 insertion and a mutant incapable of utilizing naringenin as a carbon source was isolated. The Tn 5 transposon was found to be inserted in the fdeE gene (Hsero_1007), which encodes a monooxygenase. Two other mutant strains in fdeC (Hsero_1005) and fdeG (Hsero_1009) genes coding for a dioxygenase and a putative cyclase, resp...
RNA‐seq analyses reveal insights into the function of respiratory nitrate reductase of the diazotroph Herbaspirillum seropedicaeNARA Subscribed
Summary Herbaspirillum seropedicae is a nitrogen‐fixing β‐proteobacterium that associates with roots of gramineous plants. In silico analyses revealed that H. seropedicae genome has genes encoding a putative respiratory (NAR) and an assimilatory nitrate reductase (NAS). To date, little is known about nitrate metabolism in H. seropedicae , and, as this bacterium cannot respire nitrate, the function of NAR remains unknown. This...
