Re-evaluating the nature, origins and roles of terpenes in Eucalyptus. 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 ....Re-evaluating the nature, origins and roles of terpenes in Eucalyptus. 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.Read moreRead less
