Non-nodulating Agrobacterium-like strains identified among root nodule isolates of common bean were labeled with gusA, a reporter gene encoding beta-glucuronidase (GUS). Bean plants were then co-inoculated with an infective Rhizobium strain and labeled transconjugants of Agrobacterium-like strains. Blue staining of nodules showed that Agrobacterium-like strains were able to colonize these symbi...
The threatened caesalpinioid legume Dimorphandra wilsonii, which is native to the Cerrado biome in Brazil, was examined for its nodulation and N(2)-fixing ability, and was compared with another, less-threatened species, D. jorgei. Nodulation and potential N(2) fixation was shown on seedlings that had been inoculated singly with five bradyrhizobial isolates from mature D. wilsonii nodules. The i...
Original Communications ß-Carboline Alkaloids from Ribes nigrum L. The deletion mutant Bradyrhizobium japonicum AP22 produces a structurally altered exo-polysaccharide. The nodulation of two cultivars each of Glycine max and Glycine soja, and cultivars of Macroptilium atropurpureum and Vigna radiata, infected with this mutant was examined in order to analyze the role of the exopolysaccharide in...
In order to study the effect of planting dates and genistein on nitrogen content and nodulation of three annual Medicago species (Medicago polymorpha cv. Santiago M. rigidula cv. Ragidula, and M. radiata cv. Radiata), an experimental study was conducted during 2004-2005 on the Research Farm of Faculty of Agriculture, Tarbiat Modares University, Tehran (35°43′N and 51°8′E). The factors were arra...
Restoration and maintenance of soil fertility is a basic but critical ecological problem especially in the tropics where the soils are nutrient deficient particularly P and N. The degraded soils are reclaimed through afforestation programmes with multifarious forest legume tree species along with beneficial microbes. Acacia nilotica, commonly known as Indian Gum-Arabic Tree and locally „Babul‟ ...
Effect of Rhizobia Inoculation and Starter-N on Nodulation, Shoot Biomass and Yield of Grain Legumes
Establishment of symbiosis between certain host plants and nitrogen-fixing bacteria ("rhizobia") depends on type 3 effector proteins secreted via the bacterial type 3 secretion system (T3SS). Here, we report that the open reading frame y4zC of strain NGR234 encodes a novel rhizobial type 3 effector, termed NopT (for nodulation outer protein T). Analysis of secreted proteins from NGR234 and T3SS...
