Role of inoculum sources in Rhynchosporium population dynamics and epidemics on barley

Lead Research Organisation: Rothamsted Research
Department Name: Plant Biology & Crop Science

Abstract

Rhynchosporium leaf blotch of barley, caused by the fungus Rhynchosporium secalis, is of increasing importance in world agriculture. It is the most serious disease on winter and spring barley in the UK, causing substantial losses nationally, despite expenditure of £50M per year on fungicides. The disease is difficult to control with fungicides, as the fungus can exist for a long period in the crop without causing symptoms. A severe epidemic may then emerge without warning. The sources of infection responsible for such epidemics are not well understood. We have recently discovered, for instance, that contaminated seed may be an important primary source of the disease. This project aims to clarify the origin and early dynamics of epidemics using molecular techniques (quantitative PCR) that can detect and quantify the DNA of the pathogen in barley plants before symptoms occur. The same techniques can also detect genetic characteristics of the fungus, such as mating type, virulence, and genes responsible for resistance to fungicides. Each season, epidemics will be monitored on both winter (October-sown) and spring (March-sown) barley. Work will also be done on historical spring barley samples archived at Rothamsted over 150 years, and on samples from current crops from at least 10 sites in England, Scotland and Ireland. We aim to study short-term and long-term changes in the pathogen population. Knowledge from this project will be combined with new information from related projects being funded by BBSRC LINK, Defra, HGCA and SEERAD (at ADAS, and in Scotland, SAC and SCRI) to develop guidelines for crop husbandry and agronomic practices to reduce R. secalis population size and genetic variation to achieve sustainable control of rhynchosporium disease of barley.

Technical Summary

Rhynchosporium secalis causes a polycyclic disease (many pathogen generations per season), which is an increasing problem on both winter and spring barley crops in the UK. Rhynchosporium control has been eroded during the last two decades by the ability of R. secalis to break down host resistance genes and to develop resistance to several classes of fungicides. To achieve more sustainable control, a better understanding of factors affecting R. secalis population dynamics is required. New methods to detect and quantify R. secalis DNA during the long symptomless phase early in epidemics now make it possible to study factors affecting R. secalis population dynamics over the whole season. Task 1 will test the hypothesis that seed-borne inoculum of R. secalis plays an important role in the development of rhynchosporium epidemics on barley crops each season. PCR-based assays will be used to monitor the development of R. secalis in different host plant tissues (seed, roots, stem and leaves) at regular intervals throughout the growing season, even in the absence of disease symptoms. To determine whether sexually-produced ascospores might also be a source of infection and variation in the pathogen population, spore samplers will be used to examine potential production of air-borne ascospores in different locations. AFLP fingerprinting will be used to assess the genetic structure of R. secalis populations in relation to location, cultivar (host resistance factors) and inoculum source (e.g. seed, debris). Virulence testing, using the UK Cereal Pathogen Virulence Survey will also provide genetic information about sources. Task 2 will test whether quantification of early symptomless R. secalis (by PCR) can be used to predict rhynchosporium epidemic severity and understand barley cultivar resistance, irrespective of environmental and agronomic factors. Short-term dynamics will be studied using samples from untreated and fungicide-treated plots in commercial trials (different cultivars at >20 locations in England, Scotland, Ireland) at a few specific stages during the growing season. R. secalis population dynamics will be assessed by observing changes with time in amounts of DNA by quantitative PCR. PCR results will be compared with visual assessments on epidemic (symptom) development in the same plots. To better understand relationships between early symptomless and later symptomatic infection, work will be done with genotypes from a mapping population selected as representative of different resistance phenotypes. Task 3 will test hypotheses (e.g. genetic changes in R. secalis populations) to explain the increase in severity of rhynchosporium epidemics since the mid 20th century. Rothamsted has a long-term experiment on continuous cultivation of spring barley since 1852. At the end of each season, leaf/stem material and grain have been archived. This material will also be used to investigate changes in the incidence of R. secalis in leaf and seed samples and to monitor the frequency of specific alleles associated with important traits (e.g. mating type, virulence) over the 150 year period. Results will be compared with available environmental and agronomic data. Task 4 will use the knowledge gained during this project and other related projects to develop guidelines for improved husbandry and deployment of cultivar resistance and fungicides to achieve a more sustainable control of rhynchosporium epidemics.

Description 1. The discovery that Rhynchosporium secalis can colonise barley crops extensively throughout the cropping season (from seed to seed) in the absence of visual symptoms has completely changed the understanding of the disease by industry (implications for use of fungicides, breeding programmes, AHDB barley cultivar Recommended List).

2. Markers associated with new sources of resistance to R. secalis have been identified in a barley mapping population, and methods to screen material for resistance have been improved. These findings have been exploited in a Technology Strategy Board project (SIBLINGS), led by a breeding company (KWS-UK).

3. Work with the 150-year barley archive at Rothamsted has provided unique insights into the long-term dynamics of R. secalis on barley crops (temporal patterns in the amounts of R. secalis DNA are similar to those recorded in the Defra/AHDB barley disease surveys since the 1970s). It has also provided information about the long-term dynamics of other barley pathogens.
Exploitation Route This project involved close collaboration with industry partners, who gained the following benefits from it:

Scottish Agronomy. Rhynchosporium is the most economically damaging disease of barley in the UK. As one of the largest advisory/trials groups in the UK, it is important that any information that sheds new light on the disease is disseminated through advisors, allowing them to implement any changes to disease management that may benefit growers. This project has identified seed borne transfer of the disease as significant, and identified new diagnostic tools to track movement of the disease. This will make it easier and quicker to screen for new, more resistant barley varieties and potentially reduce the requirement for fungicides.

AHDB Cereals & Oilseeds. The project has provided new information on the symptomless infection and colonisation of barley by Rhynchosporium. AHDB is funding a number of research and development projects on Rhynchosporium which will benefit from the knowledge gained and methods developed during this project. The results of the project have been communicated to growers through updating The Barley Disease Management Guide and events such as Cereals.

DuPont. DuPont have been delighted in the outcome of this project and the valuable insight it has given to the lifecycle of Rhynchosporium. This better understanding of the sources of inoculum and development of the disease has re-ignited discussion on control of the disease and has led to a number of theories as to how existing and future chemicals might be better used. This has led DuPont to become part of the TSB project to build upon this research to explore some of the theories relating to chemical usage whilst others further the genetic research.

Agrii. The barley crop is an important part of our customers' rotations, allowing early entry for winter oilseed rape which is the most effective break crop. However it tends to be treated less carefully than winter wheat and can therefore deliver variable yields, decreasing overall profitability. Agrii's involvement in this project has allowed us to better understand the most challenging part of barley management, i.e. reliable disease control, and enable us to advise our customers how to achieve better consistency in this crop's performance.

KWS. KWS UK Ltd led a Technology Strategy Board project entitled 'Symptomless Infection of BarLey: resIstance breediNG and integrated crop protection Strategies (SIBLINGS)'. The project consortium includes SCRI and University of Hertfordshire. This project aims to deliver more effective control of Rhynchosporium of barley through understanding its life cycle. The project uses new knowledge about the symptomless infection of barley obtained in this BBSRC LINK project to develop new varieties that are more durably resistant to Rhynchosporium and therefore protected against yield loss. Novel molecular and microscopy methods using GFP-tagged pathogen isolates will be used to generate knowledge of resistance mechanisms. The project consortium includes DuPont and Agrii, who will develop crop protection strategies which are strategically well directed for increased yield response and risk reduction. The proposal therefore represents a novel approach to both breeding for durable resistance and more effective crop protection with existing chemicals, whilst informing discovery strategies.
