APS 206 Biotechnology and Food Security

Level 2
Semester 1A
Credits 10
Recommended Requisite APS119 Comparative Physiology or APS137 Plant Physiology, Reproduction and Growth
Teaching Staff Dr Jonathan Graves, Professor Richard Leegood, Professor Julie Scholes
Co-ordinator Professor Richard Leegood


This course will:
• consider agricultural productivity, crop protection, breeding and genetic engineering of plants and will provide an introduction to:
• the production of agricultural crops.
• the biotic and abiotic factors which can affect productivity.
• the use of breeding and genetic manipulation to improve crop performance.
• Non-food uses of crops (e.g. plastics, biofuels)


This course will consist of three topics: agricultural productivity, crop protection, and breeding and genetic engineering of plants. These emphasise the production of agricultural crops, the biotic and abiotic factors which can affect productivity and the use of breeding and genetic manipulation to improve crop performance. Biotic factors include such topics as weeds, insect pests and pathogens and sink-source relationships in crop plants. Abiotic factors include economic constraints, the structure of canopies and light interception, effects of pesticides on the environment, genetic manipulation to provide resistance to pests and pathogens and the use of fertilisers and other chemicals. The course will also consider non-food uses of crops, such as generation of plastics or use of crops for biofuels.


Professor Julie Scholes (JDS)
Crop Protection 5 lectures

These lectures will examine various aspects of crop protection in developed and developing countries. Topics will include a consideration of the need for crop protection and aspects of the biological, chemical and biotechnological control of weeds, and diseases.

Professor Richard Leegood (RCL)
Agricultural Productivity 6 lectures

These lectures will cover a number of topics in agricultural productivity, including the importance of crops as sources of starch and protein, factors affecting crop production, crop canopies and light interception, sink-source relationships in crop plants, the genetic manipulation of proteins and carbohydrates, and the evolution and breeding of modern wheats, and non-food uses of crops, such as biofuels.

Dr Steve Rolfe (SAR)
Biotechnology and Agriculture 6 lectures

These lectures will examine the benefits and problems associated with traditional plant breeding techniques and genetic engineering. Particular emphasis will be placed on the expanding rold of genetic engineering in crop protection and production. Ethical issues will be presented for discussion.

DELIVERY METHOD: 18 sessions. 17 lectures plus the last session will be devoted to a class discussion.


ASSESSMENT METHOD: 1½ hour examination. Essay type questions.

FEEDBACK: During the module, lecturers will provide a set of short answer questions for formative feedback. These require you to consider high level concepts and ideas. Students can receive feedback on performance in examinations by arranging a meeting with their personal tutor at the start of the following Semester.
