    Notes: Abstract  Following screening, selection, characterization and examination of their symbiotic N2 fixation, only two Rhizobium strains (ND-16 and TAL-1860) and four lentil genotypes (DLG-103, LC-50, LC-53 and Sehore 74-3) were found to be suited to sodic soils. Interactions between salt-tolerant lentil genotypes and Rhizobium strains were found to be significant, and resulted in greater nodulation, N2 fixation (nitrogenase activity), total nitrogen, plant height, root length and grain yield in sodic soils under field conditions compared to uninoculated controls. Significantly more nodulation, nitrogenase activity, glutamine synthetase (GS) and NADH-dependent glutamate synthase (NADH-GOGAT) activities were found in normal soil as compared to the soil supplemented with 4% and 8% NaCl. Salt stress inhibited nitrogenase, GS and NADH-GOGAT activities. However, nitrogenase activity in nodules was more sensitive to salt stress than GS and NADH-GOGAT activities (NH4 + assimilation). The relevance of these findings for salt-tolerant symbionts is discussed.

    Strain-specific salt tolerance and chemotaxis ofAzospirillum brasilense and their associative N-fixation with finger millet in saline calcareous soil (1991)

    Notes: Abstract Three salt-tolerantAzospirillum brasilense strains were isolated from the roots of finger millet grown in saline calcareous soil and characterized. The effect of various salts on growth and N2ase activity of these strains was tested and strain STR1 was found more tolerant at higher concentrations of Cl-, SO4 2 and HCO3 -. Bicarbonate was found to be the most toxic. The content and concentrations of root exudates of finger millet genotypes were different and chemotaxis to sugars, amino acids, organic acids and root exudates was strain specific. Under salt stress, significant interactions between strains and genotypes of finger millet resulted in different responses of N2ase activity, endo- and exorhizospheric population, dry weight of root, shoot and grain yield.

    Notes: Abstract Hydrolysis of 5,5′-di-substituted hydantoins with linear and cyclic side chains, to produce the corresponding α,α-dialkylated amino acids and 1-aminocycloalkane-1-carboxylic acids, using an enzyme preparation from lentil (Lens esculenta) seeds is reported for the first time. This method could be developed on a large scale and should be of interest to the chemical and pharmaceutical industries.
