Technical Summary
The project will take advantage of existing experimental resources that the consortium has been building for the past few years. These include living experiments (a reciprocal transplant experiment on 3 contrasting sites including 21 native provenances; a glasshouse provenance-progeny trial; field provenance-progeny and provenance trials) and genetic and genomic resources (a large database of mutations across the Scots pine genome and capability for high-throughput genotyping; reference genome for Dothistroma; genetic markers for Dothistroma and pine tree Lappet moth). These existing resources will be made available to the project at no cost.
We will assess distribution and variation in the threat organisms using surveys and genotyping, and study pathogen evolution by characterising genetic changes in samples from different populations. We will assess variation in the host using population genomics (high-density genotyping of samples from multiple populations in trials) and quantitative genetics (analysis of variation in phenotypic traits and extended phenotype - resistance, phenology, morphology, needle chemistry, needle endophyte community). Data from the biological studies will be unified in a spatially-structured database and used, with data on distribution, density and regeneration rates to model the introduction and spread of threat organisms and their interaction with a variable pine population. The models will be used to test scenarios for management change that emerge from stakeholder interactions.
We will use workshops, semi-structured interviews and focus groups with stakeholders (identified through stakeholder analysis) to identify, test and refine options for building resilient pine populations. This will be a dynamic process, with ongoing interaction between natural and social scientists in the consortium, and with stakeholders. Finally, we will create a template for extending the analysis to other tree species.

Description | The diversity of fungal endophytes which live in Scots pine needles are thought to protect the tree against disease. However, the actual diversity of these organisms was equivocal prior to this project, and there was limited knowldge of endophyte communities. Using Next Generation techniques this study revealed the scale of diversity of endophytes in Scots pine (c. 700 OTUs), to show that endophyte communities have clear biogeographic differences among zones, and within these zones that different tree genotypes have different endophyte communities. Additionally, a second study has now examined the effect of the tree nursery environment on the development of endophyte communities, including the collatoral effect of fungicide spraying to prevent disease on beneficial endophyte diversity. Results from this second study have revealed contrasting amplicon patterns among treatments; this shows that endophyte communities are fundamentally changed by fungicide treatments, including the declining abundance of mutualist or commensal diversity. |
Exploitation Route | The results suggest that the forestry industry should consider locally sourced seeds in order to ensure ecological compatibility between the tree genotype and the endophytes which occur in the local environment. The study also provides information on the potential negative impacts of spraying different types of fungicide, and guidance as to the appropriate use of disease control. |

Description | Engagement has continued through the use of the animated computer game - CALEDON - which combines the scientific results and messaging from the PROTREE project, with a novel interactive learning platform. Players must manage a simulated forest to achieve a series of goals, by developing plantings with different stock types, species and genetic diversity, to generate income and maintain biodiversity, while faced with threats of tree disease (which can be minimised through good decision-making). Our decision to generate a computer game was in direct response to the UK Animal and Plant Health Strategy (Animal and Plant Health in the UK: Building our science capability) Action 4: 'Generate a plan for developing appropriate plant health skills and career pathways'. It has aimed to encourage participation from a next generation of plant health scientists. Details are provided in our entries under Engagement Activities; the game had been showcased at Science Festivals across the UK, has featured in youth magazines as well material for forestry practitioners, and has been listed as an activity for schools curricula. The use of CALEDON continues to expand nationally and internationally. |

Title | Nursery trial PIPITS output with taxonomic assignments from UNITE |
Description | Next Generation Sequencing data from endophytic fungi sampled from healthy leaves of Scots pine in a common garden experiment, using controlled trials to test the impact of registered fungicides on endophyte communities as well as target pathogens. The data was generated from RNA to discriminate living from dead endophyte species. Trees were of known provenance planted; the data can be used to partition the effects of fungicides for different genotype/provenances. |

Impact | Currently working on a draft paper, that describes fungicide effects on endophytes. |
Title | Stability of Bioinformatic/DNA Extraction Protocols for Massive Sequence Data |
Description | Fungal endophytes have been sampled from surface sterilised leaves (Pinus sylvestris) by the Research Fellow (Dr Joanne Taylor). The study is now testing how variability in fungal endophyte diversity, quantified as 'operational taxonomic units' (OTUs), depends on the options for combining DNA extraction protocols and sequencing techniques. A newly developed bioinformatics pipeline* is being used to understand whether endophyte diversity derived from Next Generation Sequencing (NGS) using 454 pyrosequencing, or using Miseq, varies across complimentary DNA extraction protocols, including CTAB or Qiagen DNeasy. Analysis of this data is enabling identification of the DNA extraction methods to achieve maximum diversity for a consistent representation of community structure. This supports the aim of the PROTREE study, to robustly quantifying hidden players (endophytes) in tree disease resistance, and provides a wider understanding of optimisation of sampling for the massive sequence diversity of unidentified fungi. * Bálint, M., P.

Impact | This is a unique optimisation study that is of high relevance at a time when the wider scientific community grapples with biological/ecological interpretation of large numbers of undiscovered taxa that are present in NGS samples, especially within mycology. The impact will be conceptual and methodological, and driven by scientific output (conference presentations, papers). |

Results and Impact | To respond to a strategic need for capacity building around UK plant health, we adapted our planned public programmes to deliver a plant health computer game targeted to young teenagers. PROTREE scientists worked with game designers from a Dundee-based start-up to develop an interactive plant health learning game. The game was launched in September 2016 at the Scottish Learning Festival in Glasgow. Post launch the game has been promoted via 14 online networks within the teaching and forestry communities. Articles about the game have been published in Arb Magazine, Confor, Forestry and Timber News, CRANN, The Observer, The Scotsman and The Week. The game was featured on Radio Five Live. A programme of events to promote the game has now been completed and around 2,000 people have been engaged at seven events across the UK. Alongside the CALEDON game a mobile exhibit was developed for PROTREE and this will be used in conjunction with CALEDON at the Edinburgh (RBGE) and three regional botanic gardens during 2017. |
