Prevalence and diversity of plant parasitic nematodes in Northern Ireland grassland and cereals, and the influence of soils and rainfall
The findings suggest significant changes in nematode populations have occurred over the last several decades and the possibility that these are linked to changing climate and cropping practices are discussed, as well as future concerns for plant parasitic nematodes management. Expand
Exogenous RNA interference exposes contrasting roles for sugar exudation in host-finding by plant pathogens.

A simple method for RNA interference-induced knockdown of genes in tomato seedling roots is presented, facilitating the study of root exudate composition, and PPN responses, and this approach can underpin future efforts to understand the early stages of plant-pathogen interactions in tomato and potentially other crop plants.

Chemosensory Responses of Plant Parasitic Nematodes to Selected Phytochemicals Reveal Long-Term Habituation Traits.
The chemotactic response of two economically important PPN species, Meloidogyne incognita and Globodera pallida to selected phytochemicals are demonstrated and pharmacological evidence supporting the existence of long-term habituation traits acting via serotonergic-dependent neurotransmission is presented.

Biostimulants enhance growth and drought tolerance in Arabidopsis thaliana and exhibit chemical priming action
A readily reproducible bioassay is developed using the model plant Arabidopsis thaliana to test biostimulant efficacy under drought conditions and assess any chemical priming action. Expand
Biosecurity and emerging plant health problems in turf production and maintenance.
A First Report of Anguina pacificae in Ireland.

This study presents the first confirmed case of an A. pacificae infestation outside of North America, where the nematode's distribution is further restricted to a relatively limited coastal region. Expand
ExoRNAi, a new tool to probe plant gene function exposes contrasting roles for sugar exudation in host-finding by plant pathogens
It is demonstrated that knockdown of both SlSTP1 andSlSTP2 in tomato seedlings by the exoRNAi method is robust and specific, and that corresponding reductions of glucose and fructose, but not xylose, in collected exudate, correlate directly with reduced infectivity and stylet thrusting of M. incognita. Expand
Transcriptomic Next-Generation Sequencing approach to assessing biostimulant priming of Arabidopsis thaliana during drought stress
Biostimulants, when used in conjunction with crop management strategies, offer solutions to the ever-growing pressures to limit usage of other products in the agrochemical sector. Expand
Alternate non-molecular tools and methods for evaluating physico-chemical and phytohormone responses in biostimulant challenged plants
ExoRNAi exposes contrasting roles for sugar exudation in host-finding by plant pathogens
A simple method for RNAi-induced knockdown of genes in tomato seedling roots is presented, facilitating the study of root exudate composition, and PPN responses, and this approach can underpin future efforts to understand the early stages of plant-pathogen interactions in tomato, and potentially other crop plants.
