Abstract

Transgenic Eucalyptus camaldulensis containing both the insecticidal cry3Agene and the bar gene (conferring tolerance to the herbicide glufosinate ammonium) have been produced by Agrobacterium tumefaciens-mediated transformation of seedling explants. Transgenic plants from two lines tested were resistant to first instars of chrysomelid beetles that are important pests ofcommercial Australian eucalypt plantations. Both lines also exhibit tolerance to the broad-spectrum herbicide Liberty (R) at 6 l/ha (1.2 kg active ingredient per hectare), twice the field application rate. Transgenic insect-and herbicide-resistant eucalypts like these are likely to provide better insect and weed control options in plantations, particularly during the vulnerable establishment phase, provided that any adverse ecological impacts of releasing transgenic trees into the environment can be assessed and minimized.
