中文摘要
花的形状和颜色看似无穷无尽的多样性吸引了人类,但进化到吸引传粉者在一个最复杂和最重要的生物相互作用。该项目测试了花多样性对植物科Goodeniaceae物种形成的影响,该科与向日葵大科密切相关。古登尼亚科(400多种)是澳大利亚和太平洋岛屿物种最丰富和最美丽的植物家族之一,对澳大利亚西南部植物区系省(一个受威胁的全球生物多样性热点)尤为重要。这些植物目前的分类学分类不能准确反映它们的进化历史,因此将利用DNA序列对该组进行全面修订。数字图像分析,花对称基因的表达,以及整个发展的对称模式将被检查,以量化物种的花的形状。这些形状对多样化率的影响的假设将使用这些新的信息进行评估。本科研究人员将帮助研究昆虫传粉者与西澳大利亚州一部分物种的相互作用。来自田纳西州孟菲斯和纽约皇后区的不同社区的学生将成为该项目不可或缺的一部分,并将获得分子和进化生物学许多方面的专业知识。该项目还将有助于确定新的和潜在的稀有物种的保护状况。
英文摘要
The seemingly endless diversity of flower shapes and colors captivates humans but evolved to entice pollinators in one of the most intricate and crucial biological interactions. This project tests the impact of floral diversity on speciation in the plant family Goodeniaceae, which is closely related to the large sunflower family. Goodeniaceae (400+ species) is one of the most species-rich and beautiful plant families in Australia and the Pacific Islands, and is particularly important to the Southwestern Australian Floristic Province, a threatened global biodiversity hotspot. The current taxonomic classification of these plants does not accurately reflect their evolutionary history, so a comprehensive revision of the group will be made using DNA sequences. Digital image analysis, floral symmetry gene expression, and the patterns of symmetry throughout development will be examined to quantify the species' floral shape. Hypotheses of the impact of these shapes on rates of diversification will be assessed using this new information. Undergraduate researchers will help study the interaction of insect pollinators with a subset of species in Western Australia. Students from the diverse communities of Memphis, Tennessee and Queens, New York will be an integral part of the project and will gain expertise in many aspects of molecular and evolutionary biology. This project will also help establish the conservation status of new and potentially rare species.
