Prerequisites

  • Molecular Biology BIOL2201, Biochemistry BIOL2191.

Corequisites

  • None

Excluded Combination of Modules

  • None.

Aims

  • To give the student a thorough understanding of the interactions between plants and their major pests and pathogens, with an emphasis on understanding those interactions at the molecular level.
  • To outline how modern technology is developing new methods of protecting crops against pests and pathogens, and to set this new technology in the context of modern agriculture.
  • To conduct a supervised investigation of an area within Biological Sciences where knowledge obtained by laboratory experimentation is important.

Content

  • Molecular techniques in plant breeding.
  • Genome analysis.
  • Marker assisted gene isolation.
  • Interaction of plants with pathogens: cell signalling.
  • The oxidative burst.
  • PR proteins, cell wall modification, phytoalexins.
  • Systemic responses.
  • Fungicides.
  • Constitutive and induced defences.
  • The role of secondary metabolism.
  • The wounding response.
  • Digestive systems in phytophagous insects.
  • Detoxification mechanisms in insects.
  • Genetics and evolution in the host-predator interaction.
  • Molecular technologies for protection of plants against insects.
  • BT toxins, plant defensive proteins, other strategies.
  • Transgenic technologies: protection of crops against viruses.
  • protection of crops against nematodes.
  • Environmental impact of insect-resistant GM crops.

Learning Outcomes

Subject-specific Knowledge:
  • By the end of this module each student should be able to: Appreciate how the life cycles of microorganisms make them suitable candidates for carrying out biotechnological processes.
  • Describe the different systems used for producing recombinant proteins in microorganisms or cell cultures, and understand their advantages and limitations.
  • Understand the principles of plant genetic engineering technologies, and how they are applied to the production of transgenic crops.
  • Appreciate the evolution and deployment of cell and tissue and organ culture systems for higher mammals.
Subject-specific Skills:
  • Critically assess selected aspects of the role of biotechnology in industry and society.
Key Skills:

    Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

    • Taught Component: Teaching and learning in this component is primarily through the means of lectures and seminars.
    • Skills will be acquired through the searching, retrieval and presentation of data.
    • Knowledge will be summatively assessed through a written examination.
    • Understanding will be assessed by means of a multiple choice question test at the end of the module to ensure students have understood the material presented.
    • Project Component: Teaching and learning in this component is primarily through supervised individual laboratory work.
    • Skills will be acquired through advanced practical work and through the searching, retrieval and presentation of relevant data.
