|Semester 2 Credit Value:||10|
Modules in microbiology and genetics
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.
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.
Use of 'LATEBLIGHT' disease simulation program.
On completing the module students should have enhanced their knowledge, understanding, and appreciation of:
How pathogens attack and damage plants and how plants resist them;
Factors influencing the severity of plant disease outbreaks;
The advantages, limitations, and interrelations of different disease control methods;
How disease epidemiology and pathogen population biology influence control strategies;
The diversity of approaches to understanding plant diseases at the cellular and organismal levels, and the advantages and potential pitfalls of these approaches;
How current knowledge is being and may potentially be used to improve disease control.
Through using a disease simulation program, students should have developed their ability to interpret factors influencing disease severity and to develop strategies of disease management.

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.
The format of resits will be determined by the Board of Examiners
|Written Examination||120||2||A||80||2 essays from 4|
|Written exercise||2||M||20||Report on Computer Practicals|
The exam uses essay questions (choice of 2 from 4) 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.
