A symbiosis expressed non‐ribosomal peptide synthetase from a mutualistic fungal endophyte of perennial ryegrass confers protection to the symbiotum from insect herbivory
TLDR
The first genetic evidence that the fungal produced secondary metabolite, peramine, protects a host plant from insect herbivory is provided, confirming that peramine is the E.’festucae metabolite responsible for ASW feeding deterrent activity.
Ryegrass endophyte: a New Zealand Grassland success story
TLDR
Endophyte strains which do not produce the compounds responsible for livestock toxicoses offer exciting new possibilities in grassland agriculture.
The exploitation of epichloae endophytes for agricultural benefit
TLDR
This review weaves together the different strands of multidisciplinary research aimed at ultimately exploiting epichloae endophytes for increased pasture performance.
Importance of host plant species, Neotyphodium endophyte isolate, and alkaloids on feeding by Spodoptera frugiperda (Lepidoptera: Noctuidae) larvae.
TLDR
The deleterious consequences of endophyte infection were easily masked by other factors in tall fescue, and chemical analysis of herbage from the plants used and results from a no-choice study failed to individually implicate any of the major known alkaloids in the observed effects on S. frugiperda.
Impact of novel endophytes in perennial ryegrass on herbage production and insect pests from pastures under dairy cow grazing in northern New Zealand
TLDR
AR37 pastures had a higher ryegrass tiller density, especially after the 2008 summer drought (+130%), and less white clover than did AR1 pastures, but summer drought reduced concentrations of lolitrem B and epoxy-janthitrems to less than half the mid-summer peak concentrations in the other years.
Endophytes improve ryegrass persistence by controlling insects
Fungal endophytes reduce populations and damage by several different insect pests which alone or in combination with each other can reduce ryegrass persistence. AR1, AR37, the Standard endophytes and
Agronomic performance of AR 37-infected ryegrass in northern New Zealand
The agronomic merits of a perennial ryegrass (Lolium perenne) cultivar infected with a new endophyte (Neotyphodium lolii), AR37, were compared with the same cultivar infected with currently available
Occurrence and impact of pasture mealybug (Balanococcus poae) and root aphid (Aploneura lentisci) on ryegrass (Lolium spp.) with and without infection by Neotyphodium fungal endophytes
TLDR
It is concluded that pasture mealybug are capable of inflicting severe damage to endophyte‐free ryegrass in Canterbury, particularly during dry summer‐autumn periods.
Endophyte effects on major insect pests in Waikato dairy pasture.
TLDR
A paddock-scale field trial comparing pastures of perennial ryegrass without endophyte (Nil) or infected with the selected endophytes AR1, AR37 or the standard endophyts sown with clover was monitored for insect pests over 3 years, consistent with AR37 pastures having the lowest insect pressure.
