2. Limiting an Insect Infestation of Nitrogen-Fixing Root Nodules of the Pigeon Pea (Cajanus cajan) by Engineering the Expression of an Entomocidal 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

3. Cowpea Rhizobia Producing Dark Nodules: Use in Competition Studies
During a program of screening rhizobia from West Africa, it was found that some strains produced nodules of unusually dark appearance on cowpeas, but not on peanuts, soybeans, pigeon peas, or mung beans. The dark pigmentation was in the bacteroid zone, was not correlated with nodule effectiveness, and was additional to the leghemoglobin pigment. Only rhizobi

4. Increased Effectiveness of Competitive Rhizobium Strains upon Inoculation of Cajanus cajan
A field study was conducted in lysimeters containing 15N-enriched soil to determine the effects of four competitive rhizobium strains upon yield parameters of pigeon peas (Cajanus cajan). The greatest differences observed were in seed yields; strain P132 effected the highest seed yield (121 ± 20 g per plant), and the control strain (indigenous rhizobia) eff

5. Conservation in Soil of H2 Liberated from N2 Fixation by Hup- Nodules
Pigeon peas (Cajanus cajan) were grown in large soil columns (90-cm length by 30-cm diameter) and inoculated with four different strains of cowpea rhizobia, which varied with respect to hydrogen uptake activity (Hup). Despite the profuse liberation of H2 from Hup- nodules in vitro, H2 gas was not detected in any of the soil columns. When H2 was injected into
