    Abstract: The invention provides an isolated culture of a Neotyphodium endophyte of an Elymus canadensis host plant, wherein the endophyte reproduces asexually and enhances the agronomic characteristics of the host plant. Methods for inoculating the host plant with the endophyte, for propagating the host-endophyte combination, and for detecting the presence of the endophyte and of its metabolites within a host plant are also described.

    Abstract: The seeds of parasitic plants of the genera Striga and Orobanche will only germinate after induction by a chemical signal exuded from the roots of their host. Many of these compounds have been isolated and identified from a number of different plant species and are collectively called the strigolactones. Here we show that the strigolactone germination stimulants are derived from the carotenoid pathway. This finding is used to create crop species that do not induce germination of parasitic plant seeds anymore and therefore are resistant to parasitic plants. Also provided is a method to use chemicals and mycorrhizae to inhibit germination stimulant production to control parasitic plants. Also provided are strigolactone overproducing trap and catch crops.

    Abstract translation: Striga和Orobanche属的寄生植物的种子将在诱导后通过从其宿主的根源渗出的化学信号发芽。 许多这些化合物已经从许多不同的植物物种分离和鉴定，并且统称为晶体内酯。 在这里我们显示，晶体内酯萌发兴奋剂来自类胡萝卜素途径。 这一发现用于产生不再引起寄生植物种子萌发的作物物种，因此对寄生植物具有抗性。 还提供了使用化学品和菌根抑制发芽刺激物产生以控制寄生植物的方法。 还提供了过氧化str内酯捕获和捕获作物。

    Abstract: Non-leguminous crops, e.g. wheat, maize and rice, do not form nodules and are dependant for their nutrition on fixed nitrogen from the soil, or from chemical/nitrogenous fertilizers. The present invention provides non-leguminous plants and leguminous plants, including legumes that fail to nodulate with Rhizobia, with bacteria that enable them to fix nitrogen endophytically. Therefore, the plants contain nitrogen fixing bacteria the bacteria being located intracellularly in living plant cells.
