| Outline and Purpose of the Course | The summaries of the newly published paper related to the graduate students' works are introduced and discussed with member of laboratory. The newly obtained results are also introduced by graduate students, and are discussed. | ||
| Course Goals |
By taking this course students will further enhance their understanding of: cambium activity in trees; the mechanisms of secondary wall formation in trees; and the mechanisms of the biosynthesis and deposition of cell wall components. |
||
| Schedule and Contents |
3-6 weeks of advanced lectures are planned for each of the topics covered in this course, including the following: 1. Tracking cambium activity in trees and the characteristics of xylem and phloem cells The sessions will focus on activities unique to trees, such as those of the vascular cambium, cork cambium and heartwood, to help students learn the basics of wood formation. 2. Tracking plant cell walls, in particular the secondary wall The seminar sessions will cover the formation process of the cell walls constituting the primary types of plant biomass, using various plant materials as examples. We will focus on the formation process of the secondary wall. 3. Assessment of material properties through the quantitative analysis of cytomorphology The seminar sessions will cover the basic principles of techniques employed to obtain an accurate assessment of the morphological irregularity unique to biomass materials. 4. Synthesis of cellulose microfibrils and high-order structures such as crystals Cellulose microfibrils are the most abundant organic molecules on Earth and manifest a unique crystalline structure and ultrafine fiber morphology. The sessions will focus on various processes related to cellulose microfibrils, including cellular biosynthesis and polymerization, aggregation, crystallization, and deposition on the cell wall. 5. Analysis of the biosynthesis of lignin/hemicellulose and the diversity of their chemical structures In these seminar sessions students will discuss the characteristics of lignin and hemicellulose, constituents of the cell wall, from the perspectives of intracellular metabolism and distribution within the cell wall. 6. Effective use of tropical wood resources and wood physiology for forest conservation The sessions will provide students with an opportunity to examine the physiology and xylem formation of tropical trees?about which very little is known?by comparing them to temperate trees. |

| Evaluation Methods and Policy |
Evaluation will be based on reports, attendance, and active participation in the seminar discussions. Refer to '2017 Guide to Degree Programs' for attainment levels of evaluation. |
||
| Course Requirements | It is desirable that students understand the basic structures of xylem tissue and cell walls in trees as well as the differentiation and development processes in plants. | ||
| Study outside of Class (preparation and review) | Students are required to read the latest research articles related to their own research and present a short report. | ||
