| rna hybrid mismatch polymorphisms in australian populations of turnip yellow mosaic tymovirus. | in the mt. kosciusko alpine area of australia there are three well-separated populations of cardamine lilacina, an endemic sward-forming perennial brassica, and these are infected with turnip yellow mosaic tymovirus. the genetic variation in these viral populations has been assessed by an rna hybrid mismatch polymorphism method. about 100 isolates were examined; the genomic rna of each isolate was prepared from a shoot of a single wild c. lilacina plant. rna hybrid mismatch polymorphisms (rhmps) ... | 1993 | 8352660 |
