Much of the biodiversity of flowering plants is due to their coevolutionary relationships with animal pollinators. Each species of pollinator is attracted to a particular flower because of the flower's color, size, shape, nectar reward, or scent. Little is known about the role of specific genes that cause changes in scent that then affect pollinator behavior. The genus Mimulus (monkeyflowers) contains two species that are separated only by the preferences of their pollinators (hummingbirds and bumblebees). The two Mimulus species have marked differences in their floral scents. This proposal focuses on two questions: 1) What are the genes that underlie these scent differences in Mimulus?; and, 2) How will plants that differ in these genetic traits affect the response of hummingbird and bumblebee pollinators in nature? The work proposed here addresses broader evolutionary principles that underlie species diversity. Additionally, since insect pollination is responsible for $225 billion per year in service to agriculture, understanding the genetic and evolutionary basis of plant-pollinator interactions has important implications for food security.

开花植物的生物多样性很大程度上归因于它们与动物传粉者的共同进化关系。 由于花的颜色、大小、形状、花蜜奖励或气味，每种传粉媒介都会被特定的花所吸引。 对于导致气味变化进而影响传粉昆虫行为的特定基因的作用知之甚少。 含酸浆属（猴花）包含两个物种，它们的区别仅在于传粉媒介（蜂鸟和大黄蜂）的偏好。 这两种酸浆菌的花香有显着差异。 该提案重点关注两个问题：1）导致酸浆菌气味差异的基因是什么？ 2）这些遗传性状不同的植物将如何影响自然界中蜂鸟和熊蜂传粉者的反应？ 这里提出的工作涉及物种多样性基础的更广泛的进化原则。此外，由于昆虫授粉每年为农业带来 2250 亿美元的贡献，因此了解植物与授粉媒介相互作用的遗传和进化基础对粮食安全具有重要意义。
