  • Publication number: 20100162438
    Abstract: The present invention generally provides a method to generate broad-spectrum resistance to bacterial blight disease in plants. More specifically, the present invention provides a method to generate broad-spectrum resistance to Xanthomonas oryzae pv. oryzae, the causal agent of bacterial blight disease of rice, and enhanced resistance to Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak of rice. Xa27, an inducible bacterial blight R gene in rice, was induced by the cognate avrXa27 gene expressed in host. Rice plants carrying the avrXa27 transgene and wild-type Xa27 gene conferred resistance to incompatible and compatible pathogens, and enhanced resistance to X. oryzae pv. oryzicola strain L8. The Xa27-mediated enhanced resistance to X. oryzae pv. oryzicola was also observed in the interaction between IRBB27 and L8 harboring pHM1avrXa27. This was further verified by the fact that the Xa27 gene in IRBB27 was induced by the avrXa27 gene in bacteria.

  • Publication number: 20090099088
    Abstract: In Magnaporthe species and other plant pathogenic fungal species, the appressoriu, (infection structure) is responsible for breaching the host plant cell wall and gaining entry into the host tissues. Magnaporthe ABC3 protein is an MDR transporter that plays an important role during host penetration and also is involved in regulating fungal response to intracellular oxidative stress. The insertional mutant abc3?, in which the ABC3 efflux pump function is blocked, lacks functional appressoria and is therefore incapable of causing disease in host plants. This invention provides the abc3 nucleic acid (gene) and ABC3 protein from Magnaporthe or from Aspergillus, Ustilago or Fusarium and describes methods for reducing plant pathogenicity for important rice pathogens.

  • Patent number: 7368631
    Abstract: The present invention is directed to a method of Acacia mangium regeneration through organogenesis and a method of genetic transformation of Acacia mangium. The method of regeneration comprises inducing callus from different parts of seedlings and vegetatively micropropagated plantlets as explants; adventitious bud induction followed by pinnate leaf and bud elongation and eventually, elongated shoots were induced to root. Based on the regeneration system, a marker gene GUS under cauliflower mosaic virus promoter was introduced to Acacia mangium via Agrobacterium infection. GUS staining in the regenerated plants and Southern blot hybridization prove the incorporation of the foreign gene into the host genome and expression of the foreign gene.
