Dr Andrew Armitage joined NRI as a Senior Fellow in 2020. His work centres on the basis of pathogenicity in plant disease, the diversity of pathogens in the environment and breeding crops with durable resistance. Andrew is a member of NRI’s Agriculture, Health and Environment Department, working across the Molecular Virology and Entomology, Plant Health and Postharvest Science research themes.

Before moving to NRI, Andrew was a project leader within the Genetics, Genomics and Breeding department at NIAB EMR. Based there for six years, Andrew performed research on pathosystems covering soft-fruit, top-fruit, vegetables and ornamentals alongside supporting work on mycoprotein production. He developed pipelines for a range of genomic analyses and provided support and training within the institute and for external collaborators.

Andrew holds a BSc in Ecology (Cardiff University), a MRes in Biology (Cardiff University) and a PhD investigating taxonomy, pathology and control of Alternaria alternataa non-native fungal quarantine pathogen of apple and pear (University of Warwick in partnership with FERA).

Andrew’s expertise includes genome assembly, annotation, comparative genomics, RNAseq, variant calling, amplicon sequencing, rAmpSeq and analysis of CrisprCas9 variants. He also performs bespoke analyses for organisms of interest such as pathogen effector identification, characterisation of host-adapted regions, systematics, resistance gene discovery and development of diagnostic assays.

Andrew is a bioinformatician specialising in the evolution of pathogenicity in plant disease and breeding crops for resistance to these diseases. His core research interests focus on fungi and the oomycetes, but also include bacterial and viral systems. Andrew works across a number of horticultural pathosystems, with particular interest in the oomycete pathogens of Phytophthora and Pythium, and the fungal pathogens including Fusarium, Botrytis, Colletotrichum and Alternaria.

Research spans both fundamental science and applied science asking questions on evolution and host adaptation of a pathogen but also searching for new sources of crop resistance, developing diagnostic test for disease and targeting management strategies based upon pathogen populations in a field.

On a fundamental level, Andrew is interested in the evolution and regulation of the regions of fungal and oomycete genomes adapted for pathogenicity. How organisms partition their genome into faster and slower evolving regions is a key interest (2- and 3-speed genomes); including study of effectors (pathogenicity genes) and identification of transposons that have played major roles in genome evolution.

On an applied level, Andrew performs genome sequencing and comparative genomics to identify loci for diagnostic tests. Targeting diagnostics to the regions of the genome that determine pathogenicity is an important step to ensure specificity to the target organism. Similar analyses are also important in identifying the basis of pesticide resistance and monitoring levels of resistance in the field. He is also engaged in pre-breeding research to identify new sources of resistance to crop disease.

Current and Recent Research Projects

An enhanced toolkit for Botrytis control in protected cropping | BBSRC PACE Horticulture | PI, £1.1M | 2024 - 2028

Botrytis cinerea is a devastating pathogen of over 1000 plant species and represents the primary postharvest disease of strawberries. Beyond typical fruit rots, recent reports of severe crown-based Botrytis infections highlight an emerging challenge to the industry. An additional threat is presented by the multi-fungicide resistant species Botrytis fragariae, a novel challenge to strawberry production in the EU and USA. Monitoring and control of these three Botrytis diseases is critical, with potential losses up to 80% in the absence of control strategies.

Options for control are limited with tighter legislation on active ingredients for chemical control and due to establishment of fungicide resistance in Botrytis. As such, greater emphasis is required on the use of integrated management strategies combining in-field diagnostics for pathogen surveillance, development of durable disease resistant crops and improved deployment of microbial-biocontrols within protected systems.

Through this project we develop an advanced toolbox for precision monitoring and integrated disease management of Botrytis in protected strawberry. This work is underpinned by the fundamental study of Botrytis host-specificity, genome evolution and genomic exchange.
