Application of genomic tools for Irish pasture improvement
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2018)The conventional way to improve populations in perennial ryegrass (Lolium perenne), the most important forage grass in Ireland, is through recurrent selection. However, despite breeding for nearly a century, the rate of ... -
Effect of plant diversity and drought on the agronomic performance of intensively managed grassland communities
(Trinity College Dublin. School of Computer Science & Statistics. Discipline of Statistics, 2022)Temperate agro-ecosystems are crucial for food production and financially important for the rural economy, but can have strong environmental impacts and are threatened by increased frequency of extreme weather events. Over ... -
Evaluating the utility of 15N and 18O isotope abundance analyses to identify nitrate sources: A soil zone study
(2012)15N and 18O isotope abundance analyses in nitrate (NO3?) (expressed as ?15N-NO3? and ?18O-NO3? values respectively) have often been used in research to help identify NO3? sources in rural groundwater. However, questions ... -
An examination of the molecular control of feed efficiency in beef cattle
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2018)Global agriculture is faced with the enormous challenge of feeding a rapidly growing population while being cognizant of the environmental footprint of such endeavours. A consequence of increased meat consumption worldwide ... -
Functional Relevance of Interleukin 8 Haplotype for the Innate Immune System in Holstein-Friesian Cattle
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2021)Calves rely heavily on their innate immune response in the post-birth period before their adaptive immune system develops. Interleukin 8 (IL-8) is a major chemoattractant predominantly associated with neutrophils response ... -
Genetic variation in bulls divergent for fertility
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2017)Bovine fertility remains a critical issue underpinning the sustainability of the agricultural sector. Since the realisation of an unfavourable relationship between fertility and production traits in cattle, methods to ... -
Groundwater nitrate reduction versus dissolved gas production: A tale of two catchments
(2017)At the catchment scale, a complex mosaic of environmental, hydrogeological and physicochemical characteristics combine to regulate the distribution of groundwater and stream nitrate (NO3−). The efficiency of NO3− removal ... -
High levels of gene flow and genetic diversity in Irish populations of Salix caprea L. inferred from chloroplast and nuclear SSR markers
(2014)Background Salix caprea is a cold-tolerant pioneer species that is ecologically important in Europe and western and central Asia. However, little data is available on its population genetic structure and molecular ... -
The impact artificial sub-surface drainage on greenhouse gas emissions, change in soil carbon storage and nutrient losses from grassland
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2019)Irish dairy production sector has started an expansion process while achieving a 20% reduction in the National greenhouse gas (GHG) emissions and fulfilling the Water Framework Directive. Moreover, the 30% of Irish dairy ... -
Innate immune phenotype variation in bovine health and disease
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2023)Infectious diseases are estimated to cost the global agriculture industry $300 billion annually and present significant challenges to animal welfare. Disease burden in cattle and other livestock species also threaten ... -
Innate immune potential of bovine respiratory epithelial cells: role in viral infection
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2023)Respiratory epithelial cells have important defence activities against respiratory viruses. While their physical barrier function is well described, the molecular mechanisms responsible for how epithelial cells initiate, ... -
Marriage exchanges, seed exchanges, and the dynamics of manioc diversity
(2011)The conservation of crop genetic resources requires understanding the different variables-cultural, social, and economic-that impinge on crop diversity. In small-scale farming systems, seed exchanges represent a key mechanism ... -
Molecular genetic typing reveals further insights into the diversity of animal-associated Staphylococcus aureus
(2009)Staphylococcus aureus is an important pathogen of man, but is also able to colonize and cause disease in a wide variety of mammals and birds. An extended multilocus sequencing approach, involving multilocus sequence typing ... -
New chloroplast microsatellite markers prove to be suitable for assessing genetic diversity of Lolium perenne and other related grass species
(2012)Background and Aims Lolium perenne (perennial ryegrass) is the most important forage grass species of temperate regions. We have previously released the chloroplast genome sequence of L. perenne ‘Cashel’. Here nine chloroplast ... -
Next Generation Sequencing Reveals the Expression of a Unique miRNA Profile in Response to a Gram-Positive Bacterial Infection
(2013)MicroRNAs (miRNAs) are short, non-coding RNAs, which post-transcriptionally regulate gene expression and are proposed to play a key role in the regulation of innate and adaptive immunity. Here, we report a next generation ... -
Organic dairy farming: impacts on insect-flower interaction networks and pollination
(2011)1. Pollination interactions comprise a network of connections between ?owers and insect visitors. They are crucial for reproductive success in many angiosperms but are threatened by intensive agricultural practices. ... -
Pathogenomic analysis of the common bovine Staphylococcus aureus clone (ET3): emergence of a virulent subtype with potential risk to public health
(University of Chicago Press, 2008)A common clone (ET3) of Staphylococcus aureus is responsible for a large proportion of cases of bovine mastitis and occasionally causes zoonotic infections of humans. In the present study, we report the identification of ... -
Patterns and drivers of groundwater and stream nitrate concentrations in intensively managed agricultural catchments
(2022)The environmental loss of nitrogen in agricultural landscapes has pervasive consequences, including human health implications, eutrophication, loss of habitat biodiversity and greenhouse gas emissions. The efficacy of ... -
Regulation of bovine beta-defensin expression
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2017)Beta-defensins are a class of host defence peptides with antibacterial, antiviral and immunomodulatory roles. The bovine genome contains up to 57 putative beta-defensin genes in four syntenic clusters on different chromosomes. ...
