项目摘要

9724731 Meyerowitz This U.S-Mexico award will support Dr. Elliot Meyerowitz of the California Institute of Technology in collaboration with Dr. Elena Alvarez Buylla of the Instituto de Ecologia of the Universidad Nacional Autonoma de Mexico (UNAM). The researchers intend to study the molecular basis and evolution of the plant, Lacandonia schismatica. Lacandonia is a unique endemic plant from Chiapas, Mexico, whose flower is the only known example of a functional spatial inversion of the reproductive whorls, that is, stamens in the central whorl and carpels in the third one. Dr. Meyerowitz has been a leader in developing models for the molecular mechanisms of flower development, models which have been corroborated by studies in other flowering plants, including Arabidopsis. The researchers now plan to establish the phylogenetic relationships by using rDNA sequences as sources of characters, to clone and structurally characterize the genes similar to the ABC genes of Arabidopsis and to test in other ways the similarity or differences in the genetic control of flower development in the two genera of plants. Because of its functional uniqueness, Lacandonia provides the necessary exception to the pattern of flowers in angiosperms for a rigorous testing of molecular models. The two laboratories have complementary skills: the U.S. lab provides the expertise in molecular technology, while the Mexican lab brings to the collaboration its expertise in phylogenetic and population biology. ***

9724731 Meyerowitz这项美国 - 墨西哥奖将支持加利福尼亚理工学院的Elliot Meyerowitz博士与墨西哥纳入自动人士（UNAM）的Elena Alvarez Buylla博士合作。研究人员打算研究植物Lacandonia Sispartica的分子基础和进化。 Lacandonia是来自墨西哥Chiapas的独特特有植物，其花是生殖螺旋的功能空间反转的唯一已知例子，即中央螺旋中的雄蕊，在第三层中的皮下。 Meyerowitz博士一直是开发花朵发育分子机制的模型的领导者，这些模型已通过包括拟南芥在内的其他开花植物的研究来证实。现在，研究人员计划通过使用rDNA序列作为字符来源建立系统发育关系，克隆和结构表征类似于拟南芥ABC基因的基因，并以其他方式测试，在其他方面进行测试，或者在其他方面测试了花朵的遗传控制的相似性或差异植物的两个属。由于其功能性唯一性，Lacandonia为被子植物中花朵模式提供了必要的例外，以严格测试分子模型。这两个实验室具有互补的技能：美国实验室提供了分子技术的专业知识，而墨西哥实验室则将其在系统发育和人群生物学方面的专业知识带来了合作。 ***
