Technical Summary
Partial resistance is typically multigenic and characterised genetically as QTLs. The mechanisms of partial resistance are only just beginning to emerge. We will dissect partial resistance of crop species focusing on wheat yellow rust. We will identify and characterise resistance to wheat yellow rust by screening diverse potential sources of resistance, including materials generated and organized through WISP (synthetic wheat lines, wild emmer, alien species), global cereal collections, and mutant lines to provide new sources of partial/durable resistance against yellow rust. High density mapping populations will be generated and the genetic basis of enhanced resistance will be determined. In addition, molecular markers will be developed to enable plant breeders to select advantageous alleles. The results from this objective will enable more rapid deployment of partial resistance in agriculture.

| Description | We have shown the effectiveness of a partial resistance gene (Yr36) to UK isolates of yellow rust under field conditions. This knowledge has paved the way for breeders to introduce this resistance (which is thought to be durable) into UK varieties. We have fine mapped a major resistance gene (Yr15) which is of great importance in UK agriculture. We have developed SNP-based markers to accelerate the transfer of this gene into UK germplasm and improve the efficiency of marker assisted selection. We have discovered the emergence of new yellow rust lineages in the UK. These new isolates represent a wider range of genetic diversity than that present in the UK in the past 25 years. We have developed a new method to perform RNAseq directly from yellow-rust infected wheat leaves collected in the field (Field Pathogenomics). This has been done in collaboration with NIAB and TGAC and is opening new avenues for pathogen diagnostics directly from the field. We have cloned three major resistance genes (Yr7, Yr5, YrSP) and have developed perfect markers for breeders to deploy. |
| Exploitation Route | We are currently working with industrial partners to develop low-cost reliable assays to improve the time of detection of new pathogen isolates. |
| Sectors | Agriculture Food and Drink |
| Description | The develop of new near-diagnostic markers for the Yr15 resistance gene are currently being deployed by two commercial breeders and have been recently published. The knowledge gained from our Yr36 work has also made it an alternative gene for use in UK and is currently being pursued. The new marker data for Yr5 will be invaluable for deployment in UK and worldwide. |

| Title | Wheat Expression |
| Description | The majority of RNA-seq expression studies in plants remain underutilised and inaccessible due to the use of disparate transcriptome references and the lack of skills and resources to analyse and visualise this data. We have developed expVIP, an expression Visualisation and Integration Platform, which allows easy analysis of RNA-seq data combined with an intuitive and interactive interface. Users can analyse public and user-specified datasets with minimal bioinformatics knowledge using the expVIP virtual machine. This generates a custom web browser to visualise, sort and filter the RNA-seq data and provides outputs for differential gene expression analysis. We demonstrate expVIP's suitability for polyploid crops and evaluate its performance across a range of biologically-relevant scenarios. To exemplify its use in crop research we developed a flexible wheat expression browser (www.wheat-expression.com) which can be expanded with user-generated data in a local virtual machine environment. The open-access expVIP platform will facilitate the analysis of gene expression data from a wide variety of species by enabling the easy integration, visualisation and comparison of RNA-seq data across experiments. |

| Title | Wheat Training |
| Description | This website provides background information and practical resources to help both budding wheat scientists as well as researchers looking to expand their work into wheat. There is a need to improve crops to feed the world's growing population with the backdrop of climate change. Translation of fundamental plant biology research (e.g. from Arabidopsis thaliana) into crops such as wheat provides a potential route to deal with this challenge. However learning even simple tasks such as growing and crossing wheat plants requires time and effort, while material and methods sections in published articles are often short and cannot substitute teaching aids. This is also true for more complex topics such as the genomics aspect of wheat. |
