Abstract: The invention provides a method and compositions for detecting the presence of viable endophyte in a plant, the method comprising germinating seed and excising a young leaf, optionally preparing an extract from the young leaf, and performing antibody, nucleic acid, or preferably PCR-based methods to detect the viable endophyte, wherein at least one primer hybridizes to the intergenic region (IGS) of the ribosomal repeat region of a specific endophyte when used in a PCR-based method. The invention provides a new method for rapid identification of both viable beneficial endophytes and any viable contaminating endophytes, as opposed to any non-viable endophytes, by detecting the presence of endophytes in the first leaf of germinated plants.

Abstract: The invention relates to uses and methods relating to grass and endophyte combinations to repel avian species from the grass and endophyte combination. In particular, methods are described to select grass and endophyte combinations in order to enhance or maximize the repellent effect. Preferred endophyte and grass combinations are described which are based on the selection methods and include AR4, AR5, AR8 and AR94 (Deposit Nos. V07/029054, V07/029055, V07/029056, V07/029057) in Lolium cultivars as well as AR601, AR602, AR603, and AR604 (Deposit Nos. V07/029058, V07/029059, V07/029060, V07/029061) in Festuca cultivars.

Abstract: The invention provides a novel MYB class transcription factor gene (nucleic acid sequences, protein sequences, and variants and fragments thereof) designated MYB14 by the applicants, that is useful for manipulating the production of flavonoids, specifically condensed tannins, in plants. The invention provides the isolated nucleic acid molecules encoding proteins with at least 70% identity to any one of MYB14 polypeptide sequences of SEQ ID NO: 14 and 46 to 54. The invention also provides, constructs, vectors, host cells, plant cells and plants genetically modified to contain the polynucleotide. The invention also provides methods for producing plants with altered flavonoid, specifically condensed tannin production, making use of the MYB14 nucleic acid molecules of the invention.

Abstract: An endophyte or endophyte culture of N. lolii species is described that, in combination with a host grass does not cause typical symptoms of ryegrass toxicosis in grazing animals and also contains levels of compounds from the class of janthitrems epoxides to individually or in combination protect the host grass from pests or abiotic stresses or both. Uses and methods are also described to produce and characterise the combination as well as alternative uses for compounds from the class of janthitrem epoxide compounds.

Abstract: The present invention relates to a combination of a Neotyphodium species endophyte or endophyte culture in a symbiotic association with a host grass which association does not cause symptoms of toxicosis in animals through exclusion of ergovaline but, due to the inclusion of alkaloids including agroclavine, setoclavine or isosetoclavine, retains the ability to resist abiotic stresses and protect the grass from pests.
