Outline and Purpose of the Course Plant physiology is fundamental to all the fields, both basic and applied, related to plants and has recently seen remarkable progress. This lecture covers the whole field of plant physiology, including topics such as photosynthesis and other metabolisms, transport of nutrients and metabolites, growth and development, environmental responses, and plant hormones.

This lecture bears the same title as Plant Physiology I, offered till SY2020, but its content differs enormously. Lectures 7-10 overlap with Plant Physiology II from the first semester.
I am revising Plant Physiology II to be offered in the first semester in SY2022 to enhance its specialization, and the current course is a prerequisite for it.
Course Goals To understand major points pertaining to the absorption of water and nutrients, the primary metabolism such as photosynthesis, characteristics of growth and development, responses to light, and the synthesis/perception/signal transduction of plant hormones, and to acquire basic knowledge to take on more advanced subjects on plants.
Schedule and Contents One or two weeks will be spent on each (a total of 15 lectures). The topics to be covered are as follows:
1. Plant body plan and plant cell (1 lecture)
2. Uptake and transport of water and nutrients (1 lecture)
3. Photosynthesis (2 lectures)
4. Nitrogen and other metabolism, and translocation (1 lecture)
5. Other primary metabolisms (1 lecture)
6. Plant specialized (“secondary”) metabolisms (1 lecture)
7. Plant hormones (3 lectures)
8. Environmental responses (light) (1 lecture)
9. Embryogenesis and vegetative development (1.5 lectures)
10. Reproduction (1.5 lectures)
11. Plant biotechnology (1 lecture)

Feedback: In each class, a mini-test (with 4-6 questions about the key points of the lecture) will be administered, and the answers will be delivered in the following week's lecture. Comments and explanations are also given.
Evaluation Methods and Policy Assessment is based on attendance (attendance at more than 70% of lectures is essential), mini in-class tests (5% in total), and an exam (report submission: 95%). Assessment criteria and policy are drawn from "Assessment criteria and policy" in the current version of the Faculty of Agriculture Student Handbook.
Course Requirements The lecture assumes that students have basic knowledge of cell biology/molecular biology. It is strongly recommended that students take Cell Biology I beforehand.
Study outside of Class (preparation and review) Lecture content is limited to the key points of each week's topic. In each lecture, relevant chapters/pages from the textbook will be indicated, and it is hoped that students will prepare for and review the lecture accordingly.
