Title: U.S.-New Zealand Cooperative Research: Diversity and Evolution of Grass Mycosymbionts This award supports a long-term visit by Dr. Christopher L. Schardl of the University of Kentucky to the laboratories of Professor David Berry Scott at Massey University and Dr. G. C. M. Latch at the Department of Scientific and Industrial Research (DSIR) both located in Palmerston North, New Zealand. The objectives of the research visit are to elucidate the processes of endophyte evolution as related to host species and geographical locale, and to determine whether the sequence-based phylogeny relates to biological characteristics such as morphology, host range and alkaloid profiles of the endophytes. The study will make use of the collections of grass-endophyte association at Palmerston North. The host collaborators have extensive research experience with endophytes (Latch) and molecular plant-microbe interactions (Scott). Dr. Schardl will explore coevolutionary relationships among fungi and grasses using the tools of molecular systematics. The mycosymbionts are stably maintained for many host generations through seed dissemination. The ecological and agricultural importance of these mycosymbionts stem from the benefits they confer to their hosts, including herbivore resistance and drought tolerance.

标题：美国新西兰合作研究：肯塔基大学的克里斯托弗·L·施德尔（Christopher L. Schardl）博士对马斯西大学的戴维·贝里·斯科特（David Berry Scott）的实验室和科学和工业研究部的G. C. M. Latch（DSER）（DSIR）的北方（New Zeacton）的New Zeacerand nek New Zeacer， 研究访问的目标是阐明与宿主物种和地理位置有关的内生菌进化过程，并确定基于序列的系统发育是否与生物学特征有关，例如内生植物的形态，宿主范围和生物碱谱。 这项研究将利用北帕默斯顿的基层植物协会的集合。 寄主合作者在内生菌（闩锁）和分子植物 - 微生物相互作用（SCOTT）方面拥有丰富的研究经验。 Schardl博士将使用分子系统学工具探索真菌和草之间的共同进化关系。 通过种子传播，宿主世代稳定地维持了菌丝体。 这些菌丝体的生态和农业重要性源于他们赋予宿主的好处，包括草食动物的耐药性和耐旱性。
