BIO3023 : Plant Pathology

  • Module Leader(s): Dr Ethan Hack
  • Owning School: Biology
Semester 2 Credit Value: 10
ECTS Credits: 5.0


To illustrate the diverse and complex mechanisms and outcomes of interactions between pathogens and plants.
To show how understanding of factors determining epidemic development can be integrated with knowledge of specific disease control methods to develop control strategies that are effective, economic, and environmentally sound.
To consider the continuing challenge of pathogen evolution.
To show how research perspectives drawn from disparate disciplines complement one another.

This module considers both the basic and applied aspects of plant pathology. It introduces plant diseases, then considers how pathogens attack plants, how plants resist attack, how disease epidemics develop and how they can be described quantitatively and predicted, and how diseases are controlled. It shows how our current knowledge of plant pathology has drawn upon a wide range of research methods from disparate disciplines.

Outline Of Syllabus

Introduction: nature of plant diseases and disease resistance; the disease cycle.
Infection: host location, recognition, attachment, and penetration.
Biotrophic interactions: structure and function of haustoria.
How pathogens damage plants.
Principles of disease management.
Epidemiology: plant disease in populations.
Effects of the environment on disease development.
Disease modelling and forecasting.
Disease control with chemicals; the problem of fungicide resistance.
Disease control with resistant plants; genetics of disease resistance.
Integrated disease management.

Computer Practicals
Use of 'LATEBLIGHT' disease simulation program.

Teaching Rationale And Relationship

The lectures explain key concepts and outline illustrative examples. The final lecture is a revision session. The computer practicals helps students develop their understanding of epidemiology by using a realistic simulation model to investigate how key variables influence disease severity. Private study is necessary for students to absorb information presented in lectures, to deepen their knowledge and understanding through reading supporting references, and to analyse and report on the results of the computer practicals.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The exam uses essay questions to assess knowledge, understanding and integration of subject material obtained from lectures and additional reading. The computer practical report tests students' ability to obtain, interpret and contextualise data on disease development and effectiveness of control strategies.
