  • Publication number: 20100040736
    Abstract: The present invention relates to a method for increasing in a baked product, after baking, the level of water-soluble arabinoxylan with an average degree of polymerization ranging from 5 to 50, preferably ranging from 5 to 35, more preferably ranging from 5 to 25, said method comprising the steps of:—Preparing a dough for a baked product with flour, a mixture of flours or a mixture of flour (s) with milling fractions having a total arabinoxylan content of at least 2.0%, preferably at least 2.5%, and—Adding to said dough an enzyme preparation comprising at least one thermophilic endoxylanase in an amount at least 2-fold higher, preferably at least 3 to 6 times higher or even 10 times higher than the dose conferring 90% of the maximal bread volume increase obtained by addition of such enzyme preparation to the recipe of said baked product. Advantageously with said method baked products can be obtained that have a level of arabinoxylan of the desired type of at least 1.7%, more preferably at least 1.

  • Patent number: 6864068
    Abstract: Antifungal proteins which are analogues of the Rs-AFP2 protein and contain particular mutations in their amino acid sequence. The mutated proteins possess enhanced salt-tolerant antifungal activity. The proteins are useful for combating fungal diseases in agricultural, pharmaceutical or preservative applications.

  • Patent number: 6521590
    Abstract: Biocidal proteins capable of isolation from seeds have been characterized. The proteins have an amino acid sequence containing the common cysteine/glycine domain of Chitin-binding Plant Proteins but show substantially better activity against pathogenic fungi, a higher ratio of basic amino acids to acidic amino acids, and/or antifungal activity which results in increased hyphal branching. Antimicrobial proteins isolated from Amaranthus, Capsicum, Briza and related species are provided. The proteins show a wide range of antifungal activity and are active against Gram-positive bacteria. DNA encoding the proteins may be isolated and incorporated into vectors. Plants may be transformed with this DNA. The proteins find agricultural or pharmaceutical application as antifungal or antibacterial agents. Transgenic plants expressing the protein will show increased disease resistance.

  • Publication number: 20020035738
    Abstract: A method of protecting a plant against a pathogen is described, the method comprising inducing expression of a plant defensin gene by stimulating the jasmonate and/or ethylenc pathways. Also deseribed is a method of inducing expression of a plant defensin gene, a composition which is capable of inducing expression of a plant defensin gene and a method for screening compounds giving resistance-inducing activity. Preferably, the pathogen is a necrotrophic pathogen.
