Abstract	Seedborne, nonpathogenic, fungal endophytes are commonly found in symbiotic relationships with many members of the cool-season grass subfamily Pooideae The beneficial effects on plants possessing fungal endophytes, and the detrimental effects on consumers of fungal endophyte-infected plants are widely known The objective of our research was to determine if fungal endophytes exist in indigenous, wild Triticum (wheat) species from Turkey From the Triticum species collected, we found two different fungal endophytes Fungi identified morphologically as members of the genus Neotyphodium were found in the diploid Triticum species T dichasians (Zhuk. Bowden and T. tripsacoides (Jaub. & Spach) Bowden. The second endophyte, an Acremonium species, was found in T. columnare (Zhuk.) Morris & Sears, T. cylindricum Ces., T. monococcum L., T. neglecta Morris & Sears, T. recta Morris & Sears, T. triunciale (L.) Raspail, T. turgidum L., and T. umbellulatum (Zhuk.) Bowden. No fungal endophytes were found in T.. kotschyi (Boiss.) Bowden, T. ovatum (L.) Raspail, T. peregrinum Morris & Sears, T. speltoides (Tausch) Gren. ex Richter, and T. tauschii (Coss.) Schmal., although the number of samples tested was small for some of these species. Both Acremonium endophyte-infected and Acremonium endophyte-free plants of T. triunciale were found to occur at different frequencies at four collection sites on the Anatolian Plateau. Through two selfed generations of the plants, it was found that the Neotyphodium endophyte was transmitted to 100% of the progeny of T. dichasians and T. tripsacoides. However, the Acremonium endophytes were not transmitted in all plants that originally possessed.
