摘要: A cDNA-derived 200 bp fragment encoding a rabbit defensin NP-1 mature peptide was ligated into the GUS-less pBI121 to yield pBIC-35NP1. Tobacco leaf discs were genetically transformed with an Agrobacterium tumefaciens strain harbouring pBIC-35NP1. Northern blot analysis showed that the defensin NP-1 expression cassette was normally transcribed in transgenic plants. Resistance tests demonstrated that expression of native defensin NP-1 can confer partial resistance to the bacterial wilt pathogen, Ralstonia solanacearum.
