    Abstract

    Sorgoleones are a group of long chain benzoquinones specifically exuded in large quantities by the root hairs of Sorghum spp. Sorgoleones inhibit electron transport of higher plants and can completely inhibit both photosynthesis and respiration in sensitive seedlings. However, research on sorgoleone has focused solely on African Sorghum spp., including S.bicolor and S. halepense. Australia, by contrast, has 17 native Sorghum species which have not yet been examined with respect to their photosynthetic system,root architecture or metabolism. Eighteen Sorghum species were assembled and evaluated for sorgoleone biosynthesis, with an emphasis on pathway flux and gene regulation.

    OtherThe Weed Society of New South Wales Inc., on behalf of the Council of Australasian Weed Societies Inc., will be hosting the 21st Australasian Weeds Conference in the popular Sydney beach side suburb of Manly from 9 - 12 September 2018.  An assortment of field trips will be hosted on Thursday 13 September 2018.
    This biennial conference carries on a long tradition of bringing the weed management community together to discuss new developments and share information about cutting-edge and best weed management practices.
    The conference attracts over 250 delegates from across Australasia and globally.  Delegates will come together to network with peers, engage with industry sponsors, listen and participate in presentations and field trips on a variety of topics including; 
    - New technologies in weed management.
    - Biological, mechanical, and chemical weed control and research.
    - Herbicide resistance.
    - Weeds of crops and pastures.
    - Environmental weeds and Weeds of National Significance.
