  • Suppression of Diseases and Abiotic Stress in Rice and Other Plants by Treatment with Avirulent Burkholderia glumae
    Publication number: 20250040500
    Abstract: The avirulent strain A257 of the bacterial rice pathogen Burkholderia glumae is an effective priming material to reduce or suppress major diseases in rice and other plants. Protection includes that against bacterial panicle blight, sheath blight, and narrow brown leaf spot. A mutant derivative of A257, A257?qsmR, significantly reduces the risk that the priming agent might potentially revert to wild-type pathogenicity.

  • Recombinant constructs and systems for secretion of proteins via type III secretion systems
    Patent number: 6596509
    Abstract: One aspect of the present invention relates to a DNA construct that contains a first DNA molecule encoding a functional type III secretion system, a promoter, and a second DNA molecule encoding a protein or polypeptide capable of being secreted by the type III secretion system. The second DNA molecule is operably coupled to the promoter so that upon introduction of the DNA construct into a host cell, the encoded protein or polypeptide and the type III secretion system are expressed and the encoded protein or polypeptide is secreted. Another aspect of the present invention relates to a system that includes (i) a first DNA construct having a first DNA molecule encoding a functional type III secretion system and (ii) a second DNA construct having a promoter operably coupled to a second DNA molecule encoding a protein or polypeptide capable of being secreted by the type III secretion system.
