The purpose of plant tissue culture
and the current condition
A study of tree structure, growth, and function and how these are related to the environment.
What are trees? How can trees survive in a changing environment? This lecture will introduce the
related anatomical and physiological characteristics of the trees.
Food crops, including cereals, beans and tuber crops have been globally traded in the 21st
century. To know how the balance of food supply and demand have been changed is very
important to predict future agriculture and food industry. In this lecture The food demand,
production, and a self-sufficiency ratio in Japan and the world will be shown using statistical
data.

Freezing tolerance of tea plant
(Camellia sinensis L. var Yabukita)
Freezing tolerance (FT) is an important adaptive measure used by perennials to resist
environments with subzero temperatures. This mechanism is defined as the ability of such
plants to survive extracellular freezing, which is frequent in species found in locations where
freezing events are severe and of long duration (Sierra-Almedia et al., 2010). In the present
seminar class, at first, tea plant is generally introduced with its vulnerability to frost damages
from the micrometeorological perspective. Second, we show how to evaluate FT of tea plant
based on the results from our case study at an experimental tea garden in Kochi Prefecture in
Japan. Third, we will present the seasonality of FT in tea using two measures, electrolyte
leakage and the ice nucleation temperature of tea leaves.

Work Accidents and Occupational
Safety Management in Japanese
Forestry
Forestry is the most dangerous occupation in Japan because of its high accidents’ rate. As
working condition has been improved by introduction of high performance forestry machines
and rejuvenation of forestry workers, the features of accidents have been changing for the
last decade. This lecture aims to learn characteristic working conditions of mountainous
forestry, to understand the changes of working accidents, and to discuss desired occupational
safety managements for work safety in Japanese forestry.
Oxidative protein folding systems in
plant cells
Disulphide transfer pathways play critical roles in the development of protein storage
organelles and the biogenesis of chloroplasts. Disulphide bond formation requires the
cooperative function of disulphide-generating enzymes and disulphide carrier proteins. This
lecture focuses on recent advances in our understanding of the mechanisms and functions of
the various disulphide transfer pathways involved in oxidative protein folding in the
endoplasmic reticulum and chloroplasts of plants.
Current fish disease problems in
Kochi Prefecture, Japan
Koi herpesvirus disease by Cyprinid herpesvirus 3, coldwater disease by Flavobacterium
psychrophilum, and white spot disease by Cryptocaryon irritans have been experienced in
Kochi Prefecture, Japan. CyHV-3 causes lethal disease in common and koi carp, but
mortality by this disease has not been reported since 2011 in any rivers. Common carp
harboring CyHV-3 DNA without producing infectious virus inhabited the Kagami River, the
Monobe River, and the Wajiki River in 2013, indicating the possibility that CyHV-3 may be
reactivated in the carrier carp in future. Ayu is a popular angling fish in Japan. A large
number of artificial juvenile ayu reared in hatcheries are released every year in the Kagami
River to enhance ayu stocks. In late June 2014, there was a mass die-off of ayu in the upper
reaches of the Kagami Dam, and coldwater disease is thought to have been responsible. In
fact, F. psychrophilum isolates were detected in normal-appearing ayu over 2014 and 2015,
and were almost identified as genotype A/G-C with strong pathogenicity to ayu. The Nomi
Bay is a famous production area of greater amberjack. Mortality by white spot disease
occurred in the bay in early October and late November 2015. The greater amberjack fry
imported from southern China was suspected as the source of the causative agent.

Feeding regulatory mechanism in
animals
Animals can not live without feeding. Additionally, the feeding is critical in the animal growth
and production. Many researchers have interest in this research field. However, the
mechanism underlying the regulation of feeding has not been clarified yet.
The theme of this seminar is to introduce the current topic in the studies of feeding
regulation in animals. For the explanation, the topic is focused on the neuropeptides in the
brain. Finally, the new findings in the feeding regulation of chicks are introduced as an
example of domestic animals.

Shale Revolution in the US and
International Energy Market
The crude oil price has been dropping dramatically, because of the change of the
global demand and supply. While the global demand has been decreasing, the global
supply has not been decreasing. It is said the global surplus of oil demand is 1.5 million
barrels per day.
The crude oil production has been creasing in the US, owing to the shale
revolution, though it has recently decreased. The US is the oil import country, but
it is exporting the crude oil produced in the US. These factors give the impact to
the global energy market.
In this course we analyze the relations between the shale revolution in the US and the
international energy market.

Applied and Basic Enzymology
(Part 1)
Some basidiomycetes (white-rot fingi) are the only known organisms that can completely
break down the recalcitrant plant cell wall constituent lignin to carbon dioxide and water.
Lignin is a heterogeneous biopolymer that occurs in woody and vascular tissues, and highly
resistant towards chemical and biological degradation. In this lecture, an overview of the
properties of basidiomycetous mushrooms and the lignin-degrading enzymes produced by
basidiomycetes will be discussed.

In the multi-stage theory of carcinogenesis, carcinogenesis can be divided into four stages:
tumor initiation, tumor promotion, malignant conversion, and tumor progression. Chemical
compounds that possess tumor promoting activity are known as tumor promoters. This
lecture will provide an overview of chemistry and biology of naturally-occurring tumor
promoters, and their application for medicinal drugs.
Allelopathy is one expression of the general phenomenon of chemical interaction and is
probably of widespread significance in the functioning of natural communities. In fact, a
number of plants repress inhibitory effects on the growth of neighboring or successional
plants by releasing allelopathic chemicals into the soil, either as exudates from living tissues
or by decomposition of plant residues. Although allelopathic science is a relatively new field
of study, there exists convincing evidence that allelopathic interactions between plants play a
crucial role in both natural and manipulated ecosystems.

Signal transduction system of
bacteria.
In this lecture, I will explain about signal transduction system of bacteria. Living organisms
sense and respond to environmental conditions using an array of signal transduction systems.
Protein phosphorylation is a key mechanism by which environmental signals are transmitted
to cause changes in protein expression or activity in both eukaryotes and prokaryotes. I will
introduce an outline of protein kinases and protein phosphatases in bacteria.
Intracellular amino acid recycling
Eukaryotic cells possess degradative organelle called vacuole (in microorganism and plants) or
lysosome (in animals). Upon nitrogen starvation, these organelles degrade cytosolic proteins
via autophagic pathway. Generated amino acids are exported to the cytosol for protein
synthesis. Autophagic protein degradation has attracted increasing attentions in recent years
because of its pathological implications and therapy potentials. The basic research using
yeast cells has provided great progress in understanding the molecular basis of autophagy.
This lecture will provide the basic of molecular mechanism and physiology of autophagy. I will
also focus on the molecular machinery of amino acid transport system across the
vacuolar/lysosomal membrane and their emerging physiological significance as recent topics.
The fine structure of wood and wood
properties
Wood is a human- and eco-friendly material. Therefore, wood material market is also
increasing and demands are higher. Especially, surfacial uses are increasing, such as car
interior, cell phone casing, lump shade and so on. Many physical and chemical modifications
of wood meeting these demands, adding high values, are carried out for more and more
applications.
In this lecture, I will introduce novel materials made from wood. These materials have special
properties such as optical transparency, self-healing, moisture control and so on. This
lecture will focus not only on the utility value of these properties, but also on how the
mechanism that changes the fine structure of wood, is linked to each property.
Functions and potentials of paper
Recently, the consumption of paper is decreasing and decreasing because of the spread of
electronic devices such as smart phones. However, paper is used in everywhere in our daily
life and we can give various functions to paper. In this class, I will introduce the bases paper
production technique, types, history of paper and current situation of paper industry. Then,
some cutting-edge papers will be introduced, for example, paper which have gas barrier
ability and can be used as plastic films and we will consider the potential of paper.

Bacterial wilt caused by Ralstonia solanacearum is one of the most devastating bacterial plant
diseases on more than 200 plant species in the tropics, the subtropics, and warm temperature
regions worldwide. R. solanacearum is a soil-borne bacterium that normally invades plant
roots from the soil through wounds or natural openings where secondary roots emerge,
colonizes intercellular spaces of the root cortex and vascular parenchyma, and eventually
Biofilm formation by Ralstonia
solanacearum , leading to its virulence enters xylem vessels and spreads up into stems and leaves through the xylem. During
colonization in intercellular spaces of tomato plants, R. solanacearum strain OE1-1 forms
biofilms on tomato cells, contributing to its virulence. In this seminar, I elucidate mechanisms
of biofilm formation by R. solanacearum cells, leading to an innovative development of control
system on the bacterial wilt disease.

Arsenic is a toxic metalloid element and it is well known that arsenic exposure causes lung
and skin cancer, and birth defects. Arsenic polluted groundwater has been identified in more
than 70 countries worldwide, including Bangladesh, India, China, Vietnam, and Cambodia. As
many as 200 million people live in areas of high geogenic arsenic contamination, and many
have no other drinking or irrigation water supply, especially during the dry season. Moreover,
increasing irrigation of crop land with arsenic enriched groundwater results in elevated
arsenic content of soil and rice, causing further exposure risk even to the people in arsenic
unaffected areas. This class will make a commentary on arsenic issues in groundwater and
soil.
Aquaculture is emerging as a revolution in agriculture of global importance to humankind;
however, aquaculture farms in enclosed coastal regions of temperate areas are threatened by
blooms of harmful algae. When proliferating in coastal waters, the harmful algae sometimes
cause mass mortality of cultured and wild fish. The economic damage to the aquaculture
industry is severe and occasionally exceeds \1 billion.
I, in this lecture, explain the ecological and physiological characteristics of harmful algae and
hope that you’ll understand how harmful algae form blooms.
