Attack and Defence in Plants
Run by School of Natural Sciences
20 Credits or 10 ECTS Credits
Organiser: Dr Anil Shirsat
Overall aims and purpose
This module aims to: 1. Give students an appreciation and understanding of the strategies that plants use to cope with external challenges such as pathogen and pest attack. 2. Give students an appreciation of cutting-edge current research into plant molecular biology by discussing ongoing research within SBS.
The strategies that plants employ to respond to biotic and abiotic stresses are currently the subject of intensive research, much of it at the molecular level. This module examines how higher plants cope with external challenges such as pathogen and pest attack by initiating specific gene expression programmes that act to minimise and overcome the effects of the stress. Topics covered include changes in cell wall protein composition in response to wounding and mechanical stress; the synthesis of phytoalexins; the role jasmonate, systemin, and salicylic acid play in localised and systemic responses; the induction of the systemic acquired resistance response and the use of transgenics to unravel the function of extensin cell wall proteins within the plant. The course will be illustrated with examples of ongoing research that is currently in progress within SBS.
To gain a good mark of 60% or above the student must additionally be able to provide a wide range of appropriate examples when responding to unseen questions.
To gain a mark of 70% or above, the student must show a comprehensive understanding of the lecture material, the answer should be well organised and to the point, and examples from additional reading (not part of the course) should be provided. This answer should give the impression of the student being an authority on the subject.
A threshold mark equates to basic understanding of the lecture material and knowledge of at least parts of the underlying experimental evidence.
Appreciate that the complexity of plant defence responses is a consequence of variations of gene expression.
Research the most recent topics in plant defense and prepare a presentation.
Appreciate that plant defence responses are varied and complex and differentiated in timing.
Demonstrate knowledge of the major pathways involved in plant defence and how they can be studied at the molecular level.
Demonstrate an integrated understanding of the response of the plant to pathogen and pest attack.
Teaching and Learning Strategy
Fourteen lectures dealing with aspects of plant defense against pathogens, pests and wounding
Students should study the Powerpoint presentations and read the online research papers which are integral to understanding this module. Students will also be directed to the relevant primary literature, book sections and internet resources, which they will be expected to read during the allotted private study time
Students will be given a topic related to plant defense and be expected to review the literature and prepare a presentation. The material presented must be new i.e not already covered in the lectures.
