Vegetative Hyphal Fusion and Subsequent Nuclear Behavior in Epichloë Grass Endophytes
Epichloë species (including the former genus Neotyphodium) are fungal symbionts of many agronomically important forage grasses, and provide their grass hosts with protection from a wide range of biotic and abiotic stresses. Epichloë species include many interspecific hybrids with allodiploid-like genomes, which may provide the potential for combined traits or recombination to generate new trait...
متن کاملPCR assay based on a microsatellite-containing locus for detection and quantification of Epichloë endophytes in grass tissue.
A PCR assay which allows detection and quantification of Epichloë endophytes in tissues of the grass Bromus erectus is described. PCR with specific primers flanking a microsatellite-containing locus (MS primers) amplified fragments 300 to 400 bp in length from as little as 1.0 pg of fungal genomic DNA in 100 ng of DNA from infected plant material. When annealing temperatures were optimized, all...
متن کاملEpichloë Endophytes Alter Inducible Indirect Defences in Host Grasses
Epichloë endophytes are common symbionts living asymptomatically in pooid grasses and may provide chemical defences against herbivorous insects. While the mechanisms underlying these fungal defences have been well studied, it remains unknown whether endophyte presence affects the host's own defences. We addressed this issue by examining variation in the impact of Epichloë on constitutive and he...
متن کاملGenetic diversity of Neotyphodium fungal endophytes in three Iranian grass species using AFLP molecular markers
Genetic diversity of fungal endophytes, Neotyphodium species, was studied in grasses Festuca arundinacea, F. pratensis and Lolium perenne using AFLP markers. Fungi were isolated from the host leaf sheaths and Neotyphodium species were selected based on morphological characteristics. To confirm identity of selected fungi belonging to the genus Neotyphodium, polymerase chain reaction was perform...
متن کاملAdvances in Research on Epichloë endophytes in Chinese Native Grasses
Epichloë fungal endophytes are broadly found in cool-season grasses. The symbiosis between these grasses and Epichloë may improve the abiotic and biotic resistance of the grass plant, but some Epichloë species produce alkaloids that are toxic for livestock. Therefore, it is important to understand the characteristics of the grass-Epichloë s symbiosis so that the beneficial aspects can be preser...
