This action funds Sven Nelson of Washington State University to conduct a research project in Biological Sciences during the summer of 2013 at the RIKEN Plant Science Center in Yokohama, Japan. The project title is "Investigating the Roles of Two Plant Hormones, Gibberellin and Abscisic Acid, in Arabidopsis Seed Dormancy." The host scientist is Dr. Mitsunori Seo.The balance between seed dormancy and germination is governed by two plant hormones, abscisic acid (ABA) and gibberellin (GA). Dormancy is a period during which seeds will not germinate, even under favorable conditions. Dormancy is released by dry storage called after-ripening. During dry after-ripening levels of ABA fall. GA levels rise when after-ripened seeds imbibe water, but it is unclear whether GA levels rise during after-ripening of dry seeds. One reason for this is that the low hormone levels in dry seeds are difficult to measure. Use of new highly sensitive techniques employed at the RIKEN institute enables us to investigate the roles of ABA and GA in seed dormancy release and germination. This research will benefit society because knowledge of the hormonal control of seed dormancy will allow better control of germination in cereal crops to prevent problems such as preharvest sprouting and poor seedling emergence. Knowledge of seed germination will also allow the development of crops with good germination and seedling emergence, a major determinant of yield. It will advance discovery in the area of seed biology while advancing learning through teaching the Fellow new technologies for hormone analysis.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, the results of this research will be broadly disseminated through publication in a peer-reviewed journal together with Dr. Seo, and through oral presentations to other scientists. In addition, a presentation about this research topic will be made to the Washington State University Future Cougars of Color to encourage high school students from underrepresented groups to pursue education or a career in science.

这项行动资助华盛顿州立大学的Sven纳尔逊于2013年夏天在日本横滨的RIKEN植物科学中心开展生物科学研究项目。 该项目的名称是“调查两种植物激素，赤霉素和脱落酸，在拟南芥种子休眠的作用。“主持人是徐光则博士。种子休眠和发芽之间的平衡是由两种植物激素，脱落酸（阿坝）和赤霉素（GA）控制的。 休眠是种子即使在有利的条件下也不会发芽的时期。 休眠是通过干燥储存来解除的，称为后熟。 在干燥后熟阿坝水平下降。 GA水平上升时，后熟种子吸水，但目前还不清楚是否GA水平上升后熟干燥种子。 其中一个原因是干种子中的低激素水平很难测量。 利用RIKEN研究所采用的新的高灵敏度技术，使我们能够研究阿坝和GA在种子休眠解除和萌发中的作用。这项研究将有益于社会，因为激素控制种子休眠的知识将允许更好地控制谷类作物的发芽，以防止收获前发芽和出苗不良等问题。 种子发芽的知识也将使作物具有良好的发芽和出苗能力，这是产量的一个主要决定因素。 它将促进种子生物学领域的发现，同时通过教授研究员激素分析的新技术来促进学习。EAPSI奖学金的更广泛影响包括为研究员提供美国以外的第一手研究经验;介绍各自所在地的科学，科学政策和科学基础设施;以及社会，文化和语言的方向。 这些活动符合NSF的目标，即在科学家，工程师和教育工作者的职业生涯早期进行国际合作教育，从而确保具有全球意识的美国科学工作者。 此外，这项研究的结果将通过与徐博士一起在同行评审的期刊上发表，并通过向其他科学家口头介绍而广泛传播。 此外，将向华盛顿州立大学未来美洲狮的颜色，以鼓励高中学生从代表性不足的群体追求教育或职业生涯在科学。
