''E. nitens'' are difficult to clonally propagate from self-rooting cuttings and coppicing techniques so clonal selections are commenced by grafting selected ''E. nitens'' onto seedling trees in the same way as horticultural crops such as apple trees.<ref name ="GPL newsletter"/> The species can be readily grafted and open-pollination seed orchards of ''E. nitens'' have been established for this purpose.<ref name="Hamilton1"/> Improved ''E. nitens'' trees are now grown as commercial pulp trees world-wide. According to Kelsey Joyce, Manager of tree breeding for GPL ‘Tree breeding is a long term commitment involving extensive research as it takes many years to grow trials for analysis and selection. The findings from this research are highly beneficial in continually improving our product and allowing us to remain competitive in a global industry’.

From water testing came the discovery of several unknown chemicals in the water samples. The presence of these chemicals in water samples made it hazardous to marine and freshwater organisms and to human cell lines. The structure and pharmaco-toxicity of these chemicals is still the subject of research.

''Eucalyptus'' spp. trees naturally produce volatile oils such as '''cineole''' and '''pineole''' - constituents of eucalyptus oil. Positive correlations exists between the concentrations of cineole and concentrations of '''

Tree seedling breeding programmes advertise that clonal propagation technologies are used. Also, the current literature on commercial tree biotechnology regularly includes terms such as ‘selective breeding’, ‘elite trees’, ‘enhance pest and environmental tolerance of plantation trees’, ‘genetic enhancement’, ‘supply and propagate superior germplasm’, ‘determine the genes controlling critical wood quality factors’, and include references to areas such as ‘gene association’, ‘gene tagging’ and ‘gene knockouts – RNAi’ technologies.<ref name ="GPL newsletter"/><ref name="Hamilton1"/>
Fifteen years ago
the ''Bacillus thuringiensis'' (Bt) endotoxin gene was incorporated into ''E. globulus'' and ''E. nitens'' and a synergistic effect of the Bt protein and the volatile oil, cineole was shown to exist.<ref name="Harcourt"/> Expressed Bt endotoxin was damaging to the midgut allowing cineole to enter the insect haemolymph and exert a toxic effect at lower concentrations than occurred when Bt endotoxin was not present.

Research and development of GM Eucalypts commenced in 1986 at DeBoer Drive Ridgley in Northern Tasmania. The '''CSIRO Division of Forestry''' worked in collaboration with '''APM, Australian Newsprint Mills, North Eucalypt Technologies''' and '''Kimberly Clarke''' under the leadership of Dr. Rod Griffin.[referenced required] It was funded by the Australian federal Government and '''North Forest Products''' (later '''Gunns Ltd'''). North Eucalypt Technologies was the R&D division of North Forest Products. The goal was to enhance ''E.nitens'' and ''E.globulus'' for Kraft pulp production increase tolerance to insect attack and herbicide sprays.

By 1999 Gillian Rasmusson, a plant scientist working for North Forest Products told the Australian Broadcasting Corportation that advances in genetic engineering could help create a super plantation tree and help take pressure off Tasmanian native forests. "Genetic engineering has the potential to reduce the time that it takes to improve the quality of your plantation or the trait that you're looking for very quickly", Rasmusson said.<ref>''Researcher moves closer to engineering supertree''' ABC Online News 21 January 1999</ref>

*"The '''University of Tasmania''' is looking at facilitating root induction and regeneration of genetically transformed eucalypts (''E. nitens, E globulus'') in the laboratory using genes from ''Agrobacterium rhizogenes''(''rol'' genes) and ''A. tumefaciens'' (auxin biosynthesis genes). ... The '''CSIRO''' aims to develop ways of ensuring sterility of transgenic trees by disrupting key genes un the flowering pathway; improve rooting ability of eucalypt cuttings; and improve the tolerance of eucalypt trees to insects and biodegradable herbicides. ... Various species of ''Eucalyptus'' and various hybrids have been transformed with insecticidal genes from the bacterium, ''Bacillus thuringiensis'' (CryIA(c) and CryIIIA); herbibicide (Basta) tolerance genes from the bacterium ''A. tumefaciens''; antibiotic (hygromycin, kanamycin) resistance marker genes from the bacterium ''E. coli''; -glucronidase report gene from ''E. coli'', green fluorscent protein marker gene from jellyfish, sense and antisense versions of ''Eucalyptus'' flowering regulatory genes or ''Arabidopsis'' (plant) equivalents; and genes involved in root develipoment from ''Arabidopsis'' or their ''Eucalyptus'' equivalents."<ref name="Senate Question"/>
