    Identification of resistance mechanisms in sugarcane to infection by Pachymetra : SRDC final report BS79S
    (BSES, 1999) McGhie, TK; Maclean, D; Smith, GR; Croft, BJ
    Project objectives- Develop techniques for studying the biochemical reactions of sugarcane to infection by Pachymetra.- Identify biochemical mechanisms of infection by Pachymetra.- Identify biochemical changes produced in sugarcane by infection with Pachymetra.- Compare the effect of chemical constituents of different sugarcane varieties on Pachymetra oospore germination and hyphal growth.- Determine which resistance mechanisms and responses of sugarcane are present in resistant varieties, ranked by glasshouse screening, as an aid to future breeding programs.

    Selection of a non-sugarcane gene for control of canegrubs : SRDC final report BS95S
    (1996) Allsopp, PG; McGhie, TK; Shepherd, K; Smith, GR
    Four types of non-sugarcane genes were investigation for potential toxictiy to canegrubs. They were: toxins from the bacterium Bacillus thuringiensis (Bt); plant proteinase inhibitors; plant lectins; and avidin. Each of these was tested in an artificial diet based on the wheatgerm and casein and developed within the project.A Bt toxin with toxicity to canegrubs was not identified. The Bt isolates tested, which had activity against New Zealand grassgrub, bound to the gut lining of larvae of Antitrogus consanguineus. This binding proved to be not sufficient for toxicity.
