Differential expression of cucumber RNA-dependent RNA polymerase 1 genes during antiviral defence and resistance.

abstract：:SUMMARY The Bipolaris sorokiniana tolerant 1 (bst1) barley mutant is derived from fast neutron-irradiated seeds of wild-type Bowman(Rph3). The induced mutation was genetically localized to a position on chromosome 5HL distal to the centromere using amplified fragment length polymorphism markers. In addition, the defen...
