Description

The principles of plant development, including the basic anatomy of higher plants, and how they grow, respond to external stimuli and reproduce. Relationship between these concepts and developments in agriculture and biotechnology.

To introduce the principles of plant growth and development, including the cellular basis of primary and secondary plant growth of vascular plants, transport processes within the plant body, physiology of acquisition of vital resources (water, minerals and carbon), and how they grow and reproduce. An overview of the responses of plants to external stimuli and adverse growth conditions will also be provided. The relevance of plant physiology principles to the exciting developments in agriculture and biotechnology will be explored where appropriate.

Learning Outcomes

As a student in this course, I will develop the ability to:
* Understand the scientific practice and principles of plant functional and developmental biology (Graduate Attribute 1: Mastery of discipline), and how knowledge about these concepts is relevant to traditional and contemporary realities of Māori society (Graduate Attribute 4: Biculturally competent and confident) and has led to improved productivity in modern agriculture (Graduate Attribute 2: Employable, innovative and enterprising): (assessment items: short revision quizzes and final exam).
* Understand basic skills in plant laboratory science and interpret experimental data (Graduate Attribute 2: Employable, innovative and enterprising): (assessment items: lab reports).
* Access and utilise the scientific literature on plant physiology (Graduate Attribute 1: Mastery of discipline and 2: Employable, innovative and enterprising): (assessment items: short library research assignments on selected lab session topics)

Transferable Skills / Pūkenga Ngaio
As a student in this course, I will develop the following skills:
1. Completing tasks in a laboratory. Important in many science-related courses and jobs. We will have lab. instructions on what is required in each lab. session. (Graduate Attribute 2: Employable, innovative and enterprising): (assessment items: lab reports).
2. Providing required information in a written form of acceptable standard. This is necessary in most science-related courses and jobs. We will provide feedback on lab reports and short library research assignments on selected lab session topics. (Graduate Attribute 2: Employable, innovative and enterprising): (assessment items: lab reports and research assignments).
3. Synthesising information. In everyday life and in many job situations you will be required to read information from different sources, construct your own understanding and shape your own viewpoint. In lectures we will discuss recent research papers in a group environment and this will develop your abilities to identify the essential elements of research outputs - you will then use in report writing. (Graduate Attribute 2: Employable, Innovative and Enterprising): (assessment items: lab reports, tests and exam).

Timetable Note

Lecture topics
There are 2 lectures per week for this course in TERMS 3 and 4. Please check the latest details on CIS.

Whole Plant Physiology (9 lectures by David Leung)
Introduction to the course
Cellular basis of primary and secondary plant growth:
-construction of the basic plant body plan during embryogenesis
-development and roles of primary and secondary meristems
The structures and functions of the phloem and xylem, including discussion on secondary xylem
Acquisition of water and mineral resources
         

Acquisition of carbon – photosynthesis, respiration, Flowering, (7 lectures by Samarth)

1. Photosynthesis – Introduction + light reactions + ATP synthesis
2. Photosynthesis – carbon assimilation I/II + CAM plants
3. Photosynthesis – Regulation + physiological considerations/stress
4. Flowering: Introduction + Florigen
5. Seasonal cues for flowering (Photoperiod + Vernalisation)
6. Internal cues for flowering (Phase Change + Sugar + Phytohormone)
7. Flower development + Biotechnological applications of studying flowering


Plant Growth and Development (8 lectures by Claudia and Chanusha)
Introduction to signals and signal transduction
Hormones
Examples for signal transduction and hormones in plants:
1) Seed development, dormancy and germination
2) Seedling responses to light and gravity
3) Fruit development, Senescence, including fruit ripening, and abscission
4) Plant immunity and growth cross talk between salicylic acid and jasmonic acid

Laboratory Work
The laboratory manual containing the Information on the laboratories is available on Learn. You will also be provided with a hard copy of this manual in the first lab class. You should read the information about a particular laboratory class before coming to the lab class.
* There are 6 labs in total that are run during TERMS 3 and 4 .
* There is only one laboratory stream.
* Lab class will not run every week.
* Two of the laboratory classes (Lab 5 and 6) that you will conduct require plants to be measured after a 24 h treatment. You will need to come back to the lab for about 1 h on the afternoon of the following day after the lab. The time when the lab will be opened is flexible to suit people’s timetables.

Passing the Course
In BIOL, we require a satisfactory level of achievement in both the theoretical aspects of the discipline and in practical activities. This means you must attend all class activities and submit all items of assessment unless you have a very good reason not to (e.g. medical reasons). A student must achieve a combined score of at least 40% in both in-course assessment and tests/exams (as defined in the course outline), AND a total score of at least 50%, to be awarded a passing grade (C or better). If you fail to achieve the 40% minimum requirement, a grade of D will be awarded, even if your total score is greater than 50%.
