| genetic diversity and biological control activity of novel species of closely related pseudomonads isolated from wheat field soils in south australia. | rhizobacteria closely related to two recently described species of pseudomonads, pseudomonas brassicacearum and pseudomonas thivervalensis, were isolated from two geographically distinct wheat field soils in south australia. isolation was undertaken by either selective plating or immunotrapping utilizing a polyclonal antibody raised against p. brassicacearum. a subset of 42 isolates were characterized by amplified 16s ribosomal dna restriction analysis (ardra), biolog analysis, and gas chromatog ... | 2000 | 10742249 |
