Requisites

Pre-requisite: BIO1101 or BIO1100 or Students must be enrolled in one of the following Programs: GCSC or GDSI or MSCN.

Rationale

Plant-microbe interactions are a central feature of the life of plants and range from advantageous symbiotic associations through to pathogenic disease states. An understanding of these interactions is essential for both commercial plant production and native vegetation management. This course examines the defining features of the most critical associations and highlights their dynamic nature.

Synopsis

The principal groups of micro-organisms which interact with plants are surveyed, particularly the fungi. Symbiotic interactions (notably those with nitrogen fixing bacteria and mycorrhizal fungi), the role of endophytes and the significance of the rhizosphere are described. A major emphasis is placed on the nature of plant pathogenesis, the disease cycle and the genetics and physiology of plant disease resistance.

This course contains a highly recommended residential school for both external and on-campus students (non-attendance will mean the student misses both an element for assessment preparation and an element of assessment).

Objectives

On successful completion of this course students should be able to:

  1. integrate knowledge of the major taxonomic classes of eukaryotic microorganisms involved in plant-microbe interactions
  2. critically evaluate the principal factors underlying plant-microbe interactions and the importance of plant-microbe symbiotic relationships in the life of plants
  3. apply expertise in the principles of plant pathogenesis
  4. display competency in laboratory and glasshouse work related to the analysis of plant-associated micro-organisms
  5. report scientific information and research results in a clear, concise and rigorous manner.

  1. This will be an open examination. Students will be provided further instruction regarding the exam by their course examiner via 精东传媒appDesk. The examination date will be available via UConnect when the official Alternate Assessment Schedule has been released.

Important assessment information

  1. Attendance requirements:
    It is the students' responsibility to attend and participate appropriately in all activities scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration. All students undertaking this course are highly recommended to attend the residential school as the residential school is linked to an assessment or an element of assessment preparation.

  2. Requirements for students to complete each assessment item satisfactorily:
    Due to COVID-19 the requirements for S2 2020 are:
    To satisfactorily complete an individual assessment item a student must achieve at least 50% of the marks for that item.

    Requirements after S2 2020:
    To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    Due to COVID-19 the requirements for S2 2020 are:
    To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course.

    Requirements after S2 2020:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course.

    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items but failed to achieve a passing Final Grade by 5% or less of the total weighted marks.

    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure (point

  5. Method used to combine assessment results to attain final grade:
    The final grades for students will be assigned on the basis of the weighted aggregate of the marks obtained for each of the summative assessment items in the course.

  6. Examination information:
    Due to COVID-19 the requirements for S2 2020 are:
    An Open Examination is one in which candidates may have access to any printed or written material and a calculator during the examination.

    Requirements after S2 2020:
    In a Closed Examination, candidates are allowed to bring only writing and drawing instruments into the examination.

  7. Examination period when Deferred/Supplementary examinations will be held:
    Due to COVID-19 the requirements for S2 2020 are:
    The details regarding deferred/supplementary examinations will be communicated at a later date.

    Requirements after S2 2020:
    Any Deferred or Supplementary examinations for this course will be held during the next examination period.

  8. 精东传媒app Student Policies:

Assessment notes

  1. Harvard (AGPS) is the referencing system required in this course. Students should use Harvard (AGPS) style in their thesis to format details of the information sources they have cited in their work. The Harvard (AGPS) style to be used is defined by the USQ Library's referencing guide.

  2. As part of the highly recommended residential school, students may be expected to complete a combination of laboratories, practical classes and assessment as advised by the course examiner.
