Transcription profiling of soybean nodulation by Bradyrhizobium japonicum.
Legumes interact with nodulating bacteria that convert atmospheric nitrogen into ammonia for plant use. This nitrogen fixation takes place within root nodules that form after infection of root hairs by compatible rhizobia. Using cDNA microarrays, we monitored gene expression in soybean (Glycine max) inoculated with the nodulating bacterium Bradyrhizobium japonicum 4, 8, and 16 days after inocul...
متن کاملChemical control of interstrain competition for soybean nodulation by Bradyrhizobium japonicum.
Previous research has shown that a significant limitation to the agricultural use of improved rhizobial inoculant strains is competition from the indigenous soil population. In this work, we sought to test whether chemical inhibitors of flavonoid-induced nod gene expression in Bradyrhizobium japonicum could be identified and utilized to affect interstrain competition for nodulation of soybeans....
متن کاملThe Soybean Rj4 Allele Restricts Nodulation by Bradyrhizobium japonicum Serogroup 123 Strains.
Of nine Bradyrhizobium japonicum serogroup 123 strains examined, 44% were found to be restricted for nodulation by cultivar Hill. Nodulation studies with soybean isoline BARC-2 confirmed that the soybean Rj4 allele restricts nodulation by the same serogroup 123 isolates. Immunological analyses indicated that B. japonicum strains in serogroups 123 and 31 share at least one surface somatic antigen.
متن کاملIdentification and use of actinomycetes for enhanced nodulation of soybean co-inoculated with Bradyrhizobium japonicum.
The utilization of actinomycetes as potential soybean (Glycine max (L.)) co-inoculants was evaluated. Soil samples from Carbondale and Belleville, Ill., were used to inoculate pre-germinated soybean plants to determine antibiotic sensitivity in the native Bradyrhizobium japonicum population. Sensitivity was in the order kanamycin > tetracycline > oxytetracycline > rifampicin > neomycin. Antagon...
متن کاملChemotaxis of Bradyrhizobium japonicum to soybean exudates.
The chemotactic response of Bradyrhizobium japonicum toward soybean seed and root exudates was examined. Assays using various isoflavones and fractionated exudate indicated that isoflavones are not the principal attractants in exudates. Likewise, induction of nod genes with isoflavones or seed exudate before assay did not enhance chemotaxis. Screening of numerous compounds revealed that only di...
