| genetic and phenotypic diversity of plant-growth-promoting bacilli isolated from wheat fields in southern brazil. | in this work, a total of 311 putative nitrogen-fixing bacilli were isolated from seven distinct wheat production zones of the rio grande do sul state, brazil. strains belonging to several species were grouped into 40 different nifh-rflp-pcr profiles. the genus paenibacillus was the most prominent group in both the rhizosphere (77.8%) and soil (79%). paenibacillus borealis was the most frequently identified species, followed by paenibacillus graminis. the remainder of the isolated bacteria belong ... | 2008 | 18490146 |
