Identification and structure elucidation of epoxyjanthitrems from Lolium perenne infected with the endophytic fungus Epichloë festucae var. lolii and determination of the tremorgenic and anti-insect activity of epoxyjanthitrem I.
(2020-08-17)Epoxyjanthitrems I-IV (1-4) and epoxyjanthitriol (5) were isolated from seed of perennial ryegrass (Lolium perenne) infected with the endophytic fungus Epichloë festucae var. lolii. Although structures for epoxyjanthitrems ... -
Temperature and plant genotype alter alkaloid concentrations in ryegrass infected with an epichloё endophyte and this affects an insect herbivore.
(Frontiers Media, 2016)Asexual Epichloё endophytes colonise agricultural forage grasses in a relationship which is mutually beneficial and provides the host plant with protection against herbivorous insects. The endophyte strain AR37 (Epichloё ...

Synergistic defensive effects of silicon and Epichloë endophytes on insect pests of agricultural grasses in New Zealand
(The University of Waikato, 2020)New Zealand has several insect pasture pests which cause economic losses of between $1.7 B and $2.3 B annually in the dairy, and ‘sheep and beef’ industries. Research on grass species defence provides insights into methods ... -
Indole diterpenoid secondary metabolites produced by the Epichloë festucae var. lolii – Lolium perenne symbiosis.
(The University of Waikato, 2019)The indole diterpenoid intermediates of lolitrems in a crude extract of Lolium perenne (L. perenne) seed infected with Epichloë festucae var. lolii (E. festucae var. lolii) and their biological activity against porina ... -
Resistance to African black beetle (Heteronychus arator) in perennial ryegrass (Lolium perenne L.) infected with AR1 endophyte
(University of Waikato, 2016)The insect pest, African black beetle (Heteronychus arator (Fabricus, 1775)) is of considerable economic cost to the New Zealand agricultural industry, in regions where the insect is established and regular outbreaks are ...
