Developing industrial technologies for “food” and “agriculture” through life science and bioinformatics

The Department of Applied Biological Sciences has three specialized fields: “Plant Sciences,” “Microbiology,” and “Animal and Marine Biology,” and six laboratories. The Department of Applied Bioscience aims to solve issues such as food problems in the face of population growth and climate change by using molecular biology and bioinformatics. We also elucidate and explore the mechanisms of biological phenomena in plants, the diverse organisms that surround them, as well as the functions of the molecules that make up their organisms.

Laboratory of Plant Molecular Physiology

Our group is focused on understanding how plants perceive and respond to environmental signals at the molecular level. We are specifically interested in the functions of chloroplasts, which are responsible for photosynthesis. By understanding chloroplast functions under various environmental stresses, we aim at improving plant stress resistance to increase the yield and quality of agricultural products. Students will study a wide range of plant physiology, including photosynthesis and environmental responses, and learn molecular biology, biochemistry, and cell biology in plants. We also work on applied research using chloroplast engineering.

Takashi SHIINA[Professor/Dean]

Organelle crosstalk in sensing and responding to stresses

Plants may not move in the way animals do; however, they sense the environment and defend themselves without moving. Crosstalk between chloroplasts/mitochondria and the nucleus is crucial for plant cell development and stress responses. Reactive oxygen species (ROS) and Ca2+ signaling have been shown to play a critical role in the organelle crosstalk. We are studying the molecular basis of organellar crosstalk in plant cells, focusing on ROS and Ca2+ signaling. This study would lead to new strategies to increase agricultural productivity.

Function of the chloroplasts for plant life

Photosynthesis is an essential chemical reaction for plant growth and occurs in a crucial organelle - the chloroplast. In response to environmental signals and leaf developmental status, chloroplasts change their morphology and functions dynamically. At the scenes of differentiation and homeostasis of chloroplast, the quality control of proteins, which are performed by many proteases, is necessary for proper chloroplast function. We focus on understanding the chloroplast protein homeostasis through the function of chloroplast proteases, which are necessary for plant growth. Our goal is to understand the regulation system and stress tolerance mechanisms of chloroplast at the molecular level.

Laboratory of Genome Biology

Genome changes were once thought to be rare events. However, now that genome analysis technology has advanced, it has become clear that the genome fluctuates frequently in farms and in the natural field. In our laboratory, we are studying the principles of genome construction and variation in plants and photosynthetic organisms, with a particular focus on the mechanisms of horizontal gene transfer across species barriers. The research results will lead to the understanding of biodiversity and evolution, and also to the development of genetic engineering technology of agricultural crops.

Laboratory of Applied Microbiology

Microorganisms can be found anywhere, and are closely related to food production and agriculture. Applied microbiology is a scientific field that deals with microorganisms and its application for our benefit. We are interested in small molecules produced by microorganisms, such as amino acids and secondary metabolites. Our goals are to improve production yields of such molecules and produce new derivatives with better biological functions. To this end, we explore new microorganisms and their functions, and analyze molecular mechanisms using chemical biology and genetic engineering approaches.

Masaru WADA[Professor/Department Head]

Make microorganisms useful for human

Microorganisms are almost the only natural enemy of humankind, and at the same time, they bring benefits to us. "Applied microbiology" handled by the Faculty of Agriculture is one of the oldest biotechnology, which was established with the development of "brewing science" that manufactures fermented foods. Amino acids used in seasonings and feed additives are produced by fermentation using microorganisms, and we are researching ways to improve their productivity. The nutritional acquisition mechanism of bifidobacteria that are useful for human health are also being investigated.

Analysis of why and how microbes produce bioactive metabolites

Microorganisms are prolific producers of bioactive secondary metabolites, which have been considered to be seeds of pharmaceuticals and agrochemicals. Better understanding of why and how microorganisms produce bioactive metabolites with complex chemical structures is a requisite for exploitation of microbial resources. To address these questions, we study filamentous fungi and their secondary metabolites.

Laboratory of Plant Environmental Microbiology

In nature, plants coexist and grow with many microbes. Some microbes infect plants and cause diseases, some do not cause diseases but are latently infectious, and some infect plants and help their growth. In order to understand these plant-microbe interactions, we are studying the growth and infection mechanisms of viruses and fungi that infect plants, as well as the reaction mechanisms by which plants recognize and counteract these viruses and fungi. Through these studies, we aim to establish control technology for plant growth.

Masanori KAIDO[Professor]

Research on the strange cohabitants called viruses

Most organisms, from bacteria to humans, are infected with viruses. And plants, too. Plant viruses use clever means one after another to spread the infection systemically. However, infection does not necessarily mean sick. In many cases, viruses coexist with the plants, or even help the growth of the host plants. I am exploring the underlying mechanisms.

How do fungi manipulate plants?

Plants live together with many fungi. In some cases, fungi inhibit plant growth, while in other cases they promote it. My research focuses on the molecules that fungi secrete during symbiosis and parasitism, and is to elucidate what molecules they use to manipulate plants.

Laboratory of Animal Science

The gastrointestinal tract plays a crucial role in physiological functions of animals such as the digestion/absorption of nutrients and immunity, among others. Thus, a gastrointestinal tract under dysbiotic conditions can cause several gastrointestinal disorders, as well as systemic diseases of the brain and metabolism. At the Laboratory of Animal Science, we investigate the functions and processes of the gastrointestinal tracts of animals using array research fields such as microbiology, immunology, and nutrition. Our laboratory aims to contribute to a healthy life in humans and animals by seeking information on how to make the gastrointestinal tract “healthy”. Our research includes not only wet-lab work but also dry-lab, in silico work, using computers.

Ryo INOUE[Professor]

Making humans and animals healthier through gastrointestinal tracts

The malfunctioning of the gastrointestinal tract can cause not only gastrointestinal disorders, but also systemic diseases of the brain and metabolism. My research group investigates the functions and processes of the gastrointestinal tracts of humans and animals by analyzing their gut microbiotas and mucosal immunity. The experimental subjects of my research group are primarily livestock and humans.

Search for novel gene expression mechanism

The genetic information is coded on DNA. The pre-mRNAs transcribed from genes are interrupted by non-coding sequences, so called ‘introns’. The introns are cut out by splicing and the spliced mRNA is translated into correct protein. For years, I have shown that seemingly unnecessary introns are actually important. I will teach basic chemistry, immunology and a bit molecular biology.

There are so many unknown things and events in hydrosphere, that’s why we call it the last frontier on the planet. We are investigating biochemical and ecological aspects of those fascinating biome in hydrosphere, including ocean and freshwater. We are also interested in foods provided by fisheries, its process and nutrition.

Taro MASUDA[Professor]

We have to take minerals from foods. Similarly, there are many enzymes that require some metals for its function. Aquatic organisms have vast diversity, and their molecule, too. I’m interested in such kind of enzymes with tremendous function that is accomplished by the interaction with metals. Also, I’m studying about ecology and phylogeography on mountainous stream fauna.

Studying the life histories of fish to conserve resources

The information about the life history of organisms, which includes their birth, reproduction, and eventual death, plays a crucial role in various fields. It serves as the foundation for determining appropriate management strategies for fisheries resources and the conservation of rare species, among other applications. Our research primarily focuses on fish species, aiming to uncover life history characteristics such as lifespan, growth patterns, and reproductive periods. We also emphasize the significance of nursery habitats in coastal areas. Furthermore, we are committed to sharing our research findings with the community and integrating them into both social and school education.

Metabolism in plastids and the unique lipid, “urushiol”

Chloroplasts are well-known as the site of photosynthesis, but they are also essential chemical factories for various compounds, such as starch, fatty acids, amino acids, isoprenoids, and plant hormones. Among these, we are particularly interested in a lipid called urushiol. Urushiol is a lipid produced only by Toxicodendron genus and is the main component of lacquer. In Japan, urushiol has been an essential material of the lacquer culture since the Jomon period (B.C.7000). It is thought that urushiol is produced by the cyclization of fatty acids produced in the plastids (chloroplasts), but the biosynthetic pathway and accumulation mechanism are still unclear. By clarifying the biosynthetic pathway of urushiol, we hope to play a role in the continuation of lacquer culture.
