My research programme is focused on forage and grass species with an emphasis on perennial ryegrass (Lolium perenne), white clover and Miscanthus and other bioenergy grasses. I have worked on the molecular, biochemical and morphological diversity of Irish and non-Irish Lolium species. Biological and agricultural important traits studied in the different projects are: seed yield and biomass related traits, self-incompatibility, flowering time, water soluble carbohydrates, fatty acid composition and abiotic stresses. Further genomics activities are the sequencing of the nuclear, chloroplast and mitochondrial genomes of ryegrass and the development of functional tools based on the sequence information.
Currently I am coordinating the FP7 funded cooperative GrassMargins project. See www.grassmargins.com
I am an active accepting editor with the journal Annals of Botany (http://aob.oxfordjournals.org/; Impact factor 4.030, 5 year impact factor 3.991).
Recently I and my colleague Dan Milbourne edited a forage breeding book deriving from the 2011 Eucarpia Fodder Crops and Amenity Grasses Meeting which was held in Dublin: Barth, S. & Milbourne, D. (eds) (2012) Breeding Strategies for sustainable forage and turf grass improvement, Springer, Dordrecht, 2012 (ISBN 978-94-007-4554-4) (DOI 10.1007/978-94-007-4555-1).
Funding for the projects comes from Teagasc, the National Development Plan, the Irish Department of Agriculture, Food and the Marine (DAFM) and FP7.
