A mutant of the enterobacterium Klebsiella pneumoniae with a defect in the hisF gene (in the histidine biosynthesis pathway) was isolated, which can only grow with high but not low ammonia concentrations. The mutated hisF product can use ammonia for

Genetics and Regulation of Nitrogen Fixation in Free-Living Bacteria ISBN: 140202178X
Our understanding of the regulation of the nitrogen-fixation process in free-living diazotrophs has advanced considerably in the last decade with information coming from a wide range of model systems. These advances have led to a much more global vie

Bacteria synthesize a number of different sigma factors which allow the co-ordinate expression of groups of genes owing to the ability of sigma to confer promoter-specific transcription initiation on RNA polymerase. In nearly all cases these sigmas b

It is now nearly 25 years since genetic studies of the process of nitrogen fixation were initiated. At that time the principal aim of this research was to identify those genes responsible for the synthesis of nitrogenase, with the expectation that th

The potential for expression of the nitrogenase Fe-protein in Nicotiana tabacum has been examined by construction of hybrid nifH and nifM genes which should target their polypeptide products to the plant chloroplast. In vitro import of these proteins

The majority of nif genes sequenced to date in a variety of diazotrophs are apparently dependent for their transcription upon the nif-specific activator, NifA, and a specific form of RNA polymerase containing a sigma factor (σ54) encoded by rpoN.

SUMMARY: In a sample of 52 wild-type isolates of Aspergillus nidulans, penicillin titre ranged from 0.0 to 14.4 units/ml. These differences in titre were under genetic control. Most of the variation between isolates was attributable to differences be

Selection for increased penicillin production among the progeny of pairwise crosses between wild-type isolates of Aspergillus nidulans resulted in the production of high-titre strains. Three crosses were made between strains with increased titre deri
