Non-rhizobial nodulation in legumes
Legume Rhizobium associations are undoubtedly form the most important N2-fixing symbiosis and play a subtle role in contributing nitrogen and maintaining/improving soil fertility. A great diversity in the rhizobial species nodulating legumes has been recognized, which belongs to α subgroup of proteobacteria covering the genera, Rhizobium, Sinorhizobium (renamed as Ensifer), Mesorhizobium, Brady...
متن کاملPeptidohydrolases of Soybean Root Nodules
Nodule extracts prepared from Glycine max var Woodworth possessed endopeptidase, aminoptidase, and carboxypeptidase actiities. Three distinct endopeptidase activities could be resolved by disc-gel electrophoresis at pH 8.8. According to their order of increasing electrophoretic mobility, the first of these enzymes hydrolyzed azocasein and n-benzoyl-LLeu-p8-naphthylamide, while the second hydrol...
متن کاملMycorrhizas and dark septate root endophytes in polar regions
We review the distributions and functions of mycorrhizas and dark septate root endophytes in polar regions. Arbuscular mycorrhizas (AM) are present in the Arctic and Antarctic to 82 oN and 63 oS, respectively, with fine endophyte being the dominant form of AM in roots at higher latitudes. Ecto(ECM) and ericoid (ERM) mycorrhizas both occur in the Arctic to 79 oN, owing to the presence of species...
متن کاملEntomocidal Gene in Its Root Nodules
A region of DNA which determined the production of the insecticidal toxin of Bacillus thuringiensis subsp. israelensis was cloned into a derivative of a broad-host-range group IncQ plasmid vector of gram-negative bacteria. The plasmid which we constructed was transferred by conjugative mobilization into a Bradyrhizobium species that nodulates pigeon peas. In this species the construction was ma...
