Estimating the term…
The present invention relates to a method for identifying and/or characterising an endophyte strain, said method including providing a plurality of samples of endophytes, subjecting said endophytes to genetic analysis; subjecting said endophytes to metabolic analysis and selecting endophytes having a desired genetic and metabolic profile. The present invention also relates to novel endophytes having a desired toxin profile wherein the endophyte produces significantly less toxic alkaloids compared with a control endophyte such as standard toxic (ST) endophyte; and/or significantly more alkaloids conferring beneficial properties compared with a control endophyte such as ST endophyte. The present invention also relates to endophyte variants having a desired genetic and metabolic profile, wherein said endophyte variants possess genetic and/or metabolic characteristics that result in a beneficial phenotype in a plant harbouring or otherwise associated with the endophyte variant. Preferably said endophyte variants are generated by polyploidisation or induced chromosome doubling.
A grass plant stably infected with a substantially purified or isolated fungal endophyte, said endophyte being non-endogenous to the grass plant and the grass plant producing a desired toxin profile, wherein the stably infected grass plant produces significantly less toxic alkaloids compared with a control plant stably infected with a control endophyte, and/or significantly more alkaloids conferring beneficial properties compared with a control plant stably infected with a control endophyte,
A method of producing a modified grass plant comprising stably infecting a host plant with a substantially purified or isolated fungal endophyte, said endophyte being non-endogenous to the grass plant and the grass plant producing a desired toxin profile, wherein the stably infected grass plant produces significantly less toxic alkaloids compared with a control plant stably infected with a control endophyte, and/or significantly more alkaloids conferring beneficial properties compared with control plant stably infected with a a control endophyte,
