Abstract: The present invention provides a heat-resistance plant gene JAZ5a and use thereof. The inventors of the present invention isolated for the first time a heat resistance gene from the plant of Brassica spp., which can greatly improve the heat-resistance ability of the plant, especially in the bolting stage. The present invention further provides a protein encoded by said gene and its preparation method, vectors and host cells containing said gene, and a method for preparing a transgenic plant containing said gene.

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.
