Advances in the positional cloning of nodulation genes in soybean, unstructured primers, identifying polymorphic DNA. DAF with mini-hairpin primers, template endonuclease cleaved DAF (tecMAAP), and arbitrary signatures from amplification profiles (ASAP) were especially successful in detecting linked polymorphisms. Putative markers were confirmed by individual anal

The use of both 16S and 23S rDNA nucleotide sequences has allowed the construction of phylogenetic trees that can be tested for congruence with symbiotic characters. In addition the development of . specif

An alternative and less-technically challenging approach may be a thorough study of non-pathogenic bacterial endophytes that already inhabit the corn plant..The discovery of a nitrogen-fixing bacterial-sugar cane association by Döbereiner and coworkers in Brazil illustra

Comparison of rhizobitoxine-induced inhibition of ,-cystathionase from different bradyrhizobia and ean cultivars. Kinetic studies showed that the nature of the RT-induced inhibition also differed between the two sources. The enzymes from bradyrhizobia exhibited inhibition that was [RT]-dependent, whereas the enzymes from soybean showed a time-dependent inhibition. These contrasting characteristic

Detection of genetic variation in , USDA 110 variants using DNA fingerprints generated with GC richn . USDA 110 variants 1-110, L2-110, and MN-110. Unique markers have now been identified which could be examined further to determine if they explain the differences in symbiotic nitrogen fixation between USDA 110 variants.

These results and our earlier studies indicate that membrane CLOSs represent one of many different classes of bioactive metabolites made by . bv. . which elicit more intense symbiosis-related responses in whit

Enhanced competitiveness of a , mutant strain improved for nodulation and nitrogen fixation,genetic markers for rifampicin and streptomycin resistance, was significantly higher for strain TA-11NOD. than for strain I-110ARS. Overall, for the two years and the two soybean genotypes, the yield obtained with TA-11NOD. was 6% higher than that obtained with I-HOARS. Competition experiments were
