var. and sp. TG-3 are filamentous fungal endophytes of perennial ryegrass () that have a substantial impact on New Zealand's agricultural economy by conferring biotic advantages to the host grass.

However, animal consumption of the plant polyphenolics, proanthocyanidins, or condensed tannins (CTs) can decrease both methane emissions and urine nitrogen levels, leading to reduced nitrous oxide emissions, and concomitantly increase animal health and production. CTs are largely absent in the foliage of important temperate pasture legumes, such as white clover (), but found in flowers and seed coats.

However, the widely used forage legume white clover () only produces CTs in flowers and trichomes and at levels too low to achieve therapeutic effects. Genetic transformation with transcription factor from was effective in inducing CTs to 0.

This process is often imperfect, resulting in endophyte-free seedlings which may have poor ecological fitness if the endophyte confers protective benefits to its host. In this study, we investigated the influence of host genetics and environment on the vertical transmission of var.
