The Mycorrhizal Fungus, Sebacina vermifera, Enhances Seed Germination and Biomass Production in Switchgrass (Panicum virgatum L)

SR Ghimire, ND Charlton, KD Craven - BioEnergy research, 2009 - Springer
Seed dormancy and slow seedling establishment are two major concerns in switchgrass (Panicum
virgatum L.) production, often resulting in a poor stand with reduced productivity. …

Interspecific hybridization and bioactive alkaloid variation increases diversity in endophytic Epichloë species of Bromus laevipes

ND Charlton, KD Craven, ME Afkhami… - FEMS microbiology …, 2014 - academic.oup.com

Alkaloid Variation Among Epichloid Endophytes of Sleepygrass (Achnatherum robustum) and Consequences for Resistance to Insect Herbivores

…, SA Jarmusch, AM Musso, ND Charlton… - Journal of chemical …, 2015 - Springer
Epichloid endophytes are well known symbionts of many cool-season grasses that may
alleviate environmental stresses for their hosts. For example, endophytes produce alkaloid …

Epichloë canadensis, a new interspecific epichloid hybrid symbiotic with Canada wildrye (Elymus canadensis)

ND Charlton, KD Craven, S Mittal, AA Hopkins… - Mycologia, 2012 - Taylor & Francis
Many Epichloë endophytes found in cool-season grasses are interspecific hybrids possessing
much or all of the genomes of two or three progenitors. Here we characterize Epichloë …
