Susanne Barth

Research Officer

Research Interests

My research programme is focused on forage species, grass weeds and cereals: perennial ryegrass (Lolium perenne), Miscanthus spp., Festulolium, Phalaris arundinacea, Dactylis glomerata, wheat, barley, blackgrass, wild oats and bromes. I am interested in genetic resources (including in situ conservation strategies), reproductive traits including self-incompatibility and flowering time, control of meiotic recombination, biomass yield and heterosis, water soluble carbohydrates, herbicides resistance in grasses and abiotic stresses.

Genomics activities have been the sequencing of the nuclear (see Velmurugan et al. 2016, Annals of Botany), chloroplast (see Diekmann et al. 2009, DNA Research) and mitochondrial genomes (Diekmann K, Hodkinson TR, Wolfe K & Barth S (2012) First insights into the mitochondrial genome of perennial ryegrass (Lolium perenne). In: Breeding Strategies for sustainable forage and turf grass improvement (Barth S and Milbourne D eds) Springer, Dordrecht, 2012 p 141 - 146 (ISBN 978-94-007-4554-4) (DOI 10.1007/978-94-007-4555-1) of ryegrass and the development of functional tools based on the sequence information.

Between 2011 and 2015 I coordinated the FP7 funded cooperative GrassMargins project.

I am a handling editor with the journal ‘Annals of Botany’ (http://aob.oxfordjournals.org/; 2016 Impact factor 4.041) (since 2009), since May 2017 I am an editor with the journal ‘Global Change Biology –Bioenergy’ ( http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1757-1707/; 2016 Impact factor 4.655).

In 2012 I 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).

I am a Research Associate with Trinity College Dublin (since 2010). I am also serving as an external scientific advisory committee member for the French national funded Biomass for the Future (BFF) project. Because of my interest in the conservation of genetic resources I am serving as a member of the Plant Panel of the Genetic Resources Scientific advisory board of the Irish Department, Agriculture, Food and the Marine.

Funding for my projects comes from EU Marie Curie Cofund/ Irish Research Council (IRC), FP7, Teagasc, & The Irish Department of Agriculture, Food and the Marine (DAFM).
