Journal ArticleDOI

Linda J. Johnson,Anouck C. M. de Bonth,Lyn R. Briggs,John R. Caradus,Sarah C. Finch,Damien J. Fleetwood,LR Fletcher,David E. Hume,Richard D. Johnson,Alison J. Popay,B. A. Tapper,Wayne R. Simpson,Christine R. Voisey,Stuart D. Card +13 more
TL;DR: This review weaves together the different strands of multidisciplinary research aimed at ultimately exploiting epichloae endophytes for increased pasture performance.
Journal ArticleDOI
Fungal endophytes for sustainable crop production.
TL;DR: It is argued that practices used in plant breeding, seed treatments and agriculture are among the reasons for the loss of fungal endophytes diversity in domesticated plants and accounts for the reduced effectiveness of some endophyte strains to confer plant benefits.
Journal ArticleDOI
High nitrogen supply and carbohydrate content reduce fungal endophyte and alkaloid concentration in Lolium perenne
Susanne Rasmussen,Anthony J. Parsons,Shalome A. Bassett,Michael J. Christensen,David E. Hume,Linda J. Johnson,Richard D. Johnson,Wayne R. Simpson,Christina Stacke,Christine R. Voisey,Hong Xue,Jonathan A. Newman +11 more
TL;DR: The results stress the need for wider quantification of fungal endophytes in the grassland-foliar endophyte context, and have implications for how introducing new cultivars, novelendophytes or increasing N inputs affect the role of endophyts in grassland ecosystems.
Journal ArticleDOI
Cloning and characterization of a cyclic peptide synthetase gene from Alternaria alternata apple pathotype whose product is involved in AM-toxin synthesis and pathogenicity.
Richard D. Johnson,Linda J. Johnson,Yasuo Itoh,Motoichiro Kodama,Hiroshi Otani,Keisuke Kohmoto +5 more
TL;DR: PCR amplified several products from A. alternata apple pathotype that showed high similarity to other fungal peptide synthetases and were specific to the apple pathotypes, and AM-toxin synthetase is therefore a primary determinant of virulence and specificity in the A. alternateata Apple pathotype/apple interaction.
Journal ArticleDOI
Deciphering endophyte behaviour: the link between endophyte biology and efficacious biological control agents.
TL;DR: This review highlights selected case studies of endophytes and discusses their lifestyles and behavioural traits, and discusses how these factors contribute towards their effectiveness as biological control agents.
