Plant-Symbiotic Fungi as Chemical Engineers: Multi-Genome Analysis of the Clavicipitaceae Reveals Dynamics of Alkaloid Loci
TLDR
The organization and dynamics of alkaloid loci and abundant repeat blocks in the epichloae suggested that these fungi are under selection for alkaloids diversification, and it is suggested that such selection is related to the variable life histories of the epICHloae, their protective roles as symbionts, and their associations with the highly speciose and ecologically diverse cool-season grasses.

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.

Reactive Oxygen Species Play a Role in Regulating a Fungus–Perennial Ryegrass Mutualistic Interaction[W]
TLDR
It is demonstrated that fungal ROS production is critical in maintaining a mutualistic fungus–plant interaction.

Histone H3K9 and H3K27 methylation regulates fungal alkaloid biosynthesis in a fungal endophyte–plant symbiosis
TLDR
The results show that the state of H3K9 and H3k27 trimethylation of E. festucae chromatin is an important regulatory layer controlling symbiosis‐specific expression of alkaloid bioprotective metabolites and the ability of this symbiont to form a mutualistic interaction with its host.

Polarity proteins Bem1 and Cdc24 are components of the filamentous fungal NADPH oxidase complex
TLDR
These results demonstrate that BemA and Cdc24 play a critical role in localizing NoxR protein to sites of fungal hyphal morphogenesis and growth and identify a potential shared ancestral link between the protein machinery required for fungal polarity establishment and the Nox complex controlling cellular differentiation.

Elimination of ergovaline from a grass–Neotyphodium endophyte symbiosis by genetic modification of the endophyte
TLDR
Disruption of this gene provides a means to manipulate the accumulation of ergovaline in endophyte-infected grasses for the purpose of determining the roles of ergopeptine inendophytes-associated traits and, potentially, for ameliorating toxicoses in livestock.

The evolutionary origins of Epichloë endophytes from annual ryegrasses.
The annual Lolium (ryegrass) species were surveyed for seedborne, asexual Epichloe endophytes (i.e., Neotyphodium spp.). Endophytes that were extremely slow growing in culture were identified from ...
