ABSTRACTDEB 0091385Yan B. LinhartMultiple Roles and Consequences of Intra-specific Chemical VariabilityThis project will explore the role of plant secondary compounds such as monoterpenes as important mediators of biotic interactions such as herbivory and competition. The research will ask 1) can there be multiple consequences associated with synthesis and storage of a specific compound? 2) to what extent do results obtained in experiments apply to natural settings? The plant to be studied is Thymus vulgaris, which is a plant with odor and taste primarily defined by one monoterpene. In southern France, where much of the work is to be done, individuals belonging to one of six chemical phenotypes (or chemotypes) each has its own specific monoterpene. Terpene synthesis is under genetic control. They chemotypes show variable deterrence against herbivores and influence germination and growth of competitiors differently. Individuals of all six chemotypes will be exposed to herbivory, or competition, or a combination of both in experimental field work. The relative fitness of chemotypes will be studied. Comparisons will be made of survival and reproduction in various environmental settings.

摘要Deb 0091385YAN B. Linhartmultiple的角色和特异性化学变异性的后果，这将探讨植物二级化合物（例如单萜）作为生物相互作用的重要介体（例如草食和竞争）的作用。 研究会问1）是否会产生与特定化合物的合成和储存相关的多种后果？ 2）在实验中获得的结果在多大程度上适用于自然设置？ 待研究的植物是胸腺，这是一种具有气味的植物，味道主要由一种单苯乙烯定义。 在法国南部，要完成许多工作，属于六种化学表型之一（或化学型）的个体各自具有其自身的特定单苯乙烯。萜烯合成在遗传控制之下。 它们的化学型表现出对草食动物的变化威慑力，并以不同的方式影响竞争者的发芽和增长。 所有六种化学型的个体都将暴露于草食性或竞争中，或者在实验现场工作中两者的组合。 将研究化学型的相对适应性。 在各种环境环境中的生存和繁殖将进行比较。
