Susanne Barth

Principal Research Officer

Research Interests

My research programme is focused on forage species, grass weeds and cereals. I am interested in genetic resources (including in situ conservation strategies), reproductive traits (self-incompatibility, flowering time, control of meiotic recombination), biomass yield and heterosis, quality traits like water soluble carbohydrates, abiotic stresses (flooding, cold and drought) and herbicides resistance in grass weeds.

Genomics activities have been the sequencing the perennial ryegrass nuclear (Velmurugan et al. 2016, Annals of Botany), chloroplast (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) and the development of functional tools based on the sequence information. I took part in the consortium who assembled the Miscanthus sinensis genome (Mitros et al (2020) Genome biology of the paleotetraploid perennial C4 grass Miscanthus. Nature Communications 11: 5442 https://doi.org/10.1038/s41467-020-18923-6).

Between 2011 and 2015 I coordinated the FP7 funded cooperative GrassMargins project which focussed on bioenergy crops on marginal lands.

I am since 2009 a handling editor with the journal ‘Annals of Botany’ (http://aob.oxfordjournals.org/; 2019 Impact factor 4.0005) and since 2018 a handling editor with ‘Agronomy’ (https://www.mdpi.com/journal/agronomy; 2019 Impact factor 2.603). I served for some years on the editorial advisory board of Global Change Biology –Bioenergy.

I have edited two books: 1) 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). And 2) Barth S, Murphy-Bokern D, Kalinina O, Taylor G & Jones MB (eds.) (2016) Perennial Biomass Crops for a Resource Constrained World, Springer, Cham/Switzerland (ISBN 978-3-319-44530-4) DOI: 10.1007/978-3-319-44530-4published November 2016

I am since 2010 a Research Associate with Trinity College Dublin. 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 and a member of the ECPGR forages working group: https://www.ecpgr.cgiar.org/working-groups/forages

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).

Education

-From 1990-1996 I studied Agricultural Sciences at the University Hohenheim and Technical University Munich Weihenstephan: Area of specialization: Plant Sciences (majors: plant nutrition, plant pathology, agronomy; minors: grassland science, forestry). My thesis was on: ‘Evaluation of different Quinoa genotypes – phenology, morphology, and dry matter production’ at the Department of Crop Production and Grassland Management/Hohenheim, Prof. Aufhammer & Dr. H.P. Kaul ; finishing with Diplom Ingenieur Agrarwissenschaften (Dipl. Ing. sc. agr.). During my studies I worked as student assistant in field trials at the Institute of Crop Production and Grassland Management in Hohenheim assisting in field trials with bioenergy and fibre crops (hemp, kenaf and ramie) and alternative crops (amaranth, quinoa, and buckwheat).

-From 1997 to 2001 I completed a PhD at the Institute of Plant Breeding and Applied Genetics at the University of Hohenheim under the supervision of Prof. A.E. Melchinger and Dr. Th. Lübberstedt: PhD thesis: ‘The variability of recombination frequencies in Arabidopsis thaliana’ finishing with Dr. sc. agr., ‘magna cum laude’.
