| identification of root rot fungi in nursery seedlings by nested multiplex pcr. | the internal transcribed spacer (its) of the ribosomal dna (rdna) subunit repeat was sequenced in 12 isolates of cylindrocladium floridanum and 11 isolates of cylindrocarpon destructans. sequences were aligned and compared with its sequences of other fungi in genbank. some intraspecific variability was present within our collections of c. destructans but not in c. floridanum. three its variants were identified within c. destructans, but there was no apparent association between its variants and ... | 1996 | 8899993 |
