Rhizobial Nodulation Factors Stimulate Mycorrhizal Colonization of Nodulating and Nonnodulating Soybeans.
Legumes form tripartite symbiotic associations with noduleinducing rhizobia and vesicular-arbuscular mycorrhizal fungi. Co-inoculation of soybean (Glycine max [L.] Merr.) roots with Bradyrhizobium japonicum 61-A-101 considerably enhanced colonization by the mycorrhizal fungus Glomus mosseae. A similar stimulatory effect on mycorrhizal colonization was also observed in nonnodulating soybean muta...
متن کاملEffects of Rhizobium– Mycorrhizae Symbiosis and Foliar Application of Urea on Some Traits of Soybean
In order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. The experiment included six treatments as: Control (C), Rhizobium bacteria (R), Rhizobium bacteria + Mycorrhiza fungi (R+M), Rhizobium bacteria + F...
متن کاملEnzymatic activity of the soybean ecto-apyrase GS52 is essential for stimulation of nodulation.
Nitrogen is an essential nutrient for plant growth. In the Rhizobium-legume symbiosis, root nodules are the sites of bacterial nitrogen fixation, in which atmospheric nitrogen is converted into a form that plants can utilize. While recent studies suggested an important role for the soybean (Glycine max) ecto-apyrase GS52 in rhizobial root hair infection and root nodule formation, precisely how ...
متن کاملRole of rhizobial biosynthetic pathways of amino acids, nucleotide bases and vitamins in symbiosis.
Rhizobia require the availability of 20 amino acids for the establishment of effective symbiosis with legumes. Some of these amino acids are synthesized by rhizobium, whereas the remaining are supplied by the host plant. The supply from plant appears to be plant-type specific. Alfalfa provides arginine, cysteine, isoleucine, valine and tryptophan, and cowpea and soybean provide histidine. The p...
متن کاملComparison of Soybean-Nodulating Bradyrhizobia Community Structures Along North Latitude Between Japan and USA
Soybean (Glycine max [L.] Merr.) establishes a symbiotic relationship by infection with soybeannodulating bacteria and subsequent root nodule formation. Soybean acquires atmospheric nitrogen as ammonia through the symbiotic nitrogen fixation by soybean-nodulating rhizobia in the root nodules. The inoculation of soybean with bradyrhizobia that has high ability of nitrogen fixation is considered ...
