dc.description.abstractVertically-transmitted Epichloë endophytes are agriculturally important fungi that colonise the aerial plant tissues of cool-season grasses within the Poaceae. Plants colonised by selected strains of Epichloë have superior protection from herbivores, thus affirming the important role of these endophytes in New Zealand farming systems. However, the development and marketability of endophyte-based products is often hindered by failures of endophyte transmission. This research investigated: (1) the developmental timing of endophyte colonisation of the seed embryo; (2) the identity of soluble sugars related to endophyte aging during seed storage; (3) the comparative endophyte hyphal density in the shoot apex and florets of high- and low-transmission genotypes; and (4) the molecular mechanisms for endophyte transmission from the inflorescence primordia to the unfertilised ovary.--Excerpten_US
