US-Mexico planning visit and workshop to assess the genomic basis of local adaptation in maize

这个项目汇集了一个由美国和墨西哥研究人员组成的国际小组，调查玉米在当地适应高海拔地区的普遍情况。合作者在进化遗传学、理论群体遗传学、数量性状作图和墨西哥农业生态系统方面具有专业知识。美国学生和研究人员将前往墨西哥参加一个国际合作团队，获得表型数据收集和分析以及种子遗传图谱方面的经验。该项目的预期成果包括绘制种子种群图和分析软件。玉米（玉米是甜的）。大约9000年前，在墨西哥西南部的低地，人们从一种被称为大刍草（Zea mays ssp）的野草中驯化了大刍草。parviglumis)。在驯化之后，玉米被带到多个独立的高地地区。这些迁徙事件需要适应截然不同的环境条件。从长远来看，合作者将通过群体遗传和数量性状作图方法评估适应这些独立高地地区的基因组基础。这些数据将提供关于重复进化过程的见解，并将潜在地确定与极端温度耐受性相关的位点，这是面对气候变化的一个重要考虑因素。

This project brings together an international team of U.S. and Mexican researchers to investigate the prevalence of local adaption of maize to high elevations. Collaborators have expertise in evolutionary genetics, theoretical population genetics, quantitative trait mapping, and Mexican agro-ecosystems. U.S. students and researchers will travel to Mexico to join an international collaborative team and gain experience in phenotypic data collection and analysis as well as seed genetic mapping. The expected outcomes of the project include both mapping seed populations and analytical software. Maize (Zea mays ssp. mays) was domesticated approximately 9000 BP in the lowlands of southwest Mexico from a wild grass known as teosinte (Zea mays ssp. parviglumis). Subsequent to domestication maize was brought to multiple, independent highland regions. These migration events required adaptation to drastically different environmental conditions. In the long-term, collaborators will assess the genomic basis of adaptation to these separate highland regions through population genetic and quantitative trait mapping approaches. These data will provide insight regarding the process of repeated evolution and will potentially identify loci relevant to the tolerance of temperature extremes, an important consideration in the face of climate change.
