Dark Septate Fungal Endophytes (DSEs) have recently emerged as important ecosystem components in several different plant communities, particularly in stressful environments. Blue grama (Bouteloua gracilis), one of the most important forage grasses in North America, harbors large quantities of DSEs. Using standard molecular techniques, the investigator and his students will compare the assemblage of fungal species colonizing B. gracilis with those inhabiting another important perennial forage grass in the same study area, Sporobolus cryptandrus (sand drop seed). The comparison will help determine which species of DSEs are most likely contributing to the attenuation of environmental stresses experienced by grasses in arid habitats. A greater understanding of the ecological role of these fungi will reveal essential information about their lifecycles and, more importantly, disclose vital details about the ecological role that fungal-plant symbioses play in stressful environments. This project will provide educational and research training for at least four undergraduates per year, such that these students will obtain an in-depth knowledge of ecological genomics that is typically reserved for students pursuing a graduate degree. Training of undergraduate students from diverse backgrounds in all facets of the proposed molecular genomics, an emerging high-tech industry, is a goal of this project. In addition, the investigator will practice and learn new molecular techniques that will be integrated into the curriculum of his courses. The dissemination of these new techniques into the classroom will benefit a diverse group of undergraduates at a small liberal arts institution.

黑暗的分隔真菌内生植物（DSE）最近在几个不同的植物群落中，尤其是在压力的环境中出现了重要的生态系统成分。 Blue Grama（bouteloua gracilis）是北美最重要的饲料草之一，拥有大量的DSE。使用标准的分子技术，研究人员和他的学生将比较将芽孢杆菌定植的真菌种类与居住在同一研究区域中另一份重要的多年生草料草的孢子虫（Sporobolus cryptandrus）（沙滴种子）。比较将有助于确定哪些DSE种类最有可能导致干旱栖息地中草所经历的环境压力的衰减。对这些真菌的生态作用有更深入的了解，将揭示有关其生命周期的基本信息，更重要的是，披露了有关真菌植物共生物在压力环境中发挥的生态作用的重要细节。 该项目将为每年至少四名大学生提供教育和研究培训，以便这些学生将获得对生态基因组学的深入了解，这些知识通常是为攻读研究生学位的学生而言。该项目的目标是对拟议分子基因组学的各个方面的各个方面的各个方面的培训，这是该项目的目标。此外，研究人员将练习和学习新的分子技术，这些技术将融入他的课程课程中。这些新技术将这些新技术传播到课堂上将使小型文科机构的各种本科生受益。
