| Abstract: | Transgenic rice plants harbouring Bacillus subtilis protoporphyrinogen oxidase (Protox) gene, which is targeted into plastid, were generated by Agrobacterium-mediated transformation using a rice (Oryza sativa L. cv. Dongjin) and their gene integration at T1 generation by Southern and mRNA expression in T2 generation by Northern blotting were analyzed. Their herbicide-resistant trait was further confirmed by in vitro leaf segment assay and in planta bioassays such as seed germination assay and measurement of growth inhibition. The herbicide oxyfluorfen resistance in transgenic rice plants was not very high. The results showed that the Protox from B. subtilis can not be applicable as a gene source to generate a high level oxyfluorfen tolerance in plants. This revised version was published online in July 2006 with corrections to the Cover Date. |
