Ecological importance of Neotyphodium spp. grass endophytes in agroecosystems
Neotyphodium spp. fungal endophytes form symbiotic associations with agronomic grasses with expression ranging from mutualistic to parasitic. In general, endophyte infection frequencies seem more variable in natural compared to pastoral situations, suggesting that expression and benefits attributable to endophyte infection depend on the resource environment in which the host–endophyte complex w...
متن کاملNeotyphodium endophyte infection frequency in annual grass populations: relative importance of mutualism and transmission efficiency.
Persistence and ubiquity of vertically transmitted Neotyphodium endophytes in grass populations is puzzling because infected plants do not consistently exhibit increased fitness. Using an annual grass population model, we show that the problems for matching endophyte infection and mutualism are likely to arise from difficulties in detecting small mutualistic effects, variability in endophyte tr...
متن کاملProtein interactions and their importance
The "boom" in molecular interaction research that we have experienced in the past few years has been caused by the increasingly wide availability of high throughput technologies that can potentially provide information on several thousand pairwise interactions at a time 11 [2]. Such highthroughput studies can provide a global 'snapshot' of the molecular interactions that take place in a cell, a...
متن کاملGrass-endophyte interactions: a note on the role of monosaccharide transport in the Neotyphodium lolii-Lolium perenne symbiosis.
Symbiotic mutualistic associations of plants with ectoand endomycorrhizal and endophytic fungi are very common in natural and agricultural ecosystems; these fungi improve nutrient acquisition and ⁄ or tolerance to biotic and abiotic stresses of their hosts (Smith & Gianinazzi-Pearson, 1988; Nehls et al., 2007; Schardl et al., 2007). A major feature of associations between the heterotrophic fung...
متن کاملHybridization of Neotyphodium endophytes enhances competitive ability of the host grass.
• Associations with microbial symbionts may lead to niche differentiation of their host. Vertically transmitted Neotyphodium endophytes of grasses often hybridize in nature. Infection by these hybrid symbionts may result in different host-plant phenotypes from those caused as a result of infection by nonhybrid symbionts. Observations of wild Arizona fescue (Festuca arizonica) populations show t...
