Arabidopsis thaliana, or commonly known as mouse-ear cress, a small European weed of the mustard family, to which the cabbages, Brussel sprouts, broccoli, cauliflower, and radishes belong, has become the model flowering plant in basic studies of classical and molecular biology. Thousands of biologists are working on this organism to understand many fundamental biological processes. Worldwide interest in mouse-ear cress stems from the fact that this organism has the smallest and simplest genome among flowering plants, has a generation time of four to six weeks, and has a small size to 30 cm high (because of its small size, dozens can be grown in a small pot and several hundred thousands in a small room). These and several other attributes make the plant ideal for basic studies in biology. Yet the very basic information on Arabidopsis, especially on its nearest relatives, limits, number of species, and various aspects of its individual species is almost non-existent. To understand the origin of this organism, basic systematic studies on the genus are urgently needed, and living material of all taxa should be made available. The proposed research is designed to address these very problems. Intensive field work will be done in central Asia, especially the adjacent portions of China, Pakistan, India, Afghanistan, Kazakhstan, Kyrgyzstan, and Tajikistan, which represent the center of greatest diversity of the genus. Seed collections will be deposited at the Arabidopsis Biological Resource Center at Ohio State, where they will be made available to botanists worldwide. Extensive systematic studies based on herbarium material from more than 80 herbaria will be conducted, and detailed studies on the morphology, reproductive biology, cytology, seed anatomy, and chemistry of Arabidopsis and its relatives will be done. The proposed two-year grant will result in a systematic study of Arabidopsis and will provide the scientific community with much needed living material of the various species including mouse-ear cress.

拟南芥，或通常称为鼠耳水芹， 欧洲十字花科的小杂草，卷心菜， 甘蓝，花椰菜，花椰菜和萝卜属于， 成为古典和现代植物学基础研究的模式植物， 分子生物学 成千上万的生物学家正在研究这个问题 生物体了解许多基本的生物过程。 全世界对鼠耳水芹的兴趣源于这样一个事实， 在开花植物中， 植物，有四到六个星期的世代时间，并有一个小的 大小为30厘米高（由于其体积小，可以种植数十种 在一个小罐子里，在一个小房间里有几十万）。 这些和其他几个属性使工厂的基本理想 研究生物学。 然而，关于拟南芥的最基本的信息， 特别是它最近的亲戚，限制，物种数量， 其个体物种的各个方面几乎不存在。 为了了解这种生物的起源，基本的系统研究 对属迫切需要，和生活材料的所有分类群 应该提供。 拟议的研究旨在 解决这些问题。 将在中亚进行密集的实地工作， 中国，巴基斯坦，印度，阿富汗， 代表中心的哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦 最具多样性的物种 种子收集将 保藏在俄亥俄州的拟南芥生物资源中心 它们将被提供给世界各地的植物学家。 广泛的系统研究基于植物标本馆的材料， 将进行超过80个植物标本室的研究，并对 形态学、生殖生物学、细胞学、种子解剖学， 拟南芥及其亲缘植物的化学研究。 的 拟议的两年赠款将导致系统研究， 将为科学界提供许多 所需的各种生物材料，包括鼠耳 水芹
