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.

Abstract: Described are means and methods for controlling flowering in plants. In particular, described are nucleic acid molecules which, when expressed in sense orientation or in antisense orientation, respectively, in plants lead to a prevention of flowering. Moreover, a method for controlling flowering in plants is provided which comprises the inducible restoration of flowering in plants in which flowering is prevented.

Abstract: The isolation and function of a plant LpTFL1 from Lolium perenne (perennial ryegrass) are described, along with generation of transgenic Arabidopsis ryegrass, and red fescue plants. Thc gene prevents or represses flowering of transgenic plants. Methods for using the gene to repress or prevent flowering are described.
