ng the . transformation system, Bishop and Brill. were able to locate the mutations as a cluster on the chromosome. Mutants defective in nitrogen fixation (..) were also isolated for cyanobacteria,. but, due to the lack of a gene-transfer system, no further genetic studies could be performed with thnotice 发表于 2025-3-29 01:12:14

exhibited by soybean-rhizobia and the fact that large collections of bacterial strains and soybean varieties are available, it might be possible to identify soybean cultivars that, while highly effective with a particular set of soybean-rhizobial strains, are also poorly nodulated by the indigenousInferior 发表于 2025-3-30 04:12:53
