Abstract
This disclosure provides to a new tall fescue grass endophyte (Neotyphodium coenophialum) referred to as 647, as well as to synthetic combinations of the 647 endophyte and tall fescue grass plant or tall fescue grass cultivar. This new endophyte does not produce detectable ergovaline or any other ergopeptide alkaloids which are known to be harmful to grazing livestock. Thus, the 647 endophyte can be used in combination with forage grasses. In addition, the 647 endophyte provides increased green matter yield and improved resistance to black beetles (Heteronychus arator) and other pests. Thus, the 647 endophyte can be used in combination with grasses susceptible to infection or infestation with black beetles.
Claims13
An endophyte deposited with The Centraalbureau voor Schimmelcultures (CBS) as Deposit No. CBS 133163 further comprising a recombinant nucleic acid sequence.
A synthetic endophyte/grass plant cultivar combination, comprising the endophyte deposited with The Centraalbureau voor Schimmelcultures (CBS) as Deposit No. CBS 133163 and a tall fescue grass plant cultivar.
A method of increasing the fresh weight yield of a tall fescue cultivar, increasing the dry matter of live tillers of a tall fescue cultivar, reducing black beetle damage to a tall fescue cultivar, or increasing insect resistance in a tall fescue cultivar, comprising:
- inoculating a tall fescue grass plant cultivar or seed with the endophyte deposited with The Centraalbureau voor Schimmelcultures (CBS) as Deposit No. CBS 133163;
- and
- allowing the grass plant cultivar or seed to grow, thereby increasing the fresh weight yield of the tall fescue cultivar, increasing the dry matter of live tillers of the tall fescue cultivar, reducing black beetle damage to the tall fescue cultivar, or increasing insect resistance in the tall fescue cultivar, as compared to a tall fescue grass plant cultivars without the endophyte.
