The plasmid was a linear double-stranded DNA with a molecular weight of 1·68 ± 0·06 × 106 or 2617 ± 87 bp. Weakly pathogenic isolates of R. solani, 1668 RI-1, 1271 RI-64 and 1272 RI-1, which showed abnormally slow growth, contained the plasmids, but pathogenic isolates, 1668, 1271 and 1272, showing normal growth, contained no detectable plasmid DNA. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-130-8-2067
