Terpenes give eucalypts their characteristic smell and mediate many interactions between trees and the environment. Studies of the genome show that eucalypts have more genes to make terpenes than any other plant. Our knowledge of the chemistry and roles of these terpenes is confined to leaves but almost half of the genes occur in roots, wood and bark and there is little idea what their roles are. This project will conduct the first comprehensive study of terpenes in Eucalyptus to identify where and how they are made in the plant, how the major compounds evolved and how terpenes contribute to defence against insects, atmospheric emissions and the composition of soil.

萜类化合物赋予了桉树特有的气味，并在树木与环境之间进行了许多相互作用。对基因组的研究表明，桉树比其他任何植物都有更多的基因来制造萜烯。我们对这些萜烯的化学性质和作用的了解仅限于叶子，但几乎一半的基因存在于根、木材和树皮中，而且几乎不知道它们的作用是什么。该项目将对桉树中的萜烯进行首次全面研究，以确定它们在植物中的位置和方式，主要化合物如何进化以及萜烯如何有助于抵御昆虫，大气排放和土壤成分。
