The division of Biosphere Resource Science and Technology consists of a total of 18 professional disciplines including cooperative graduate school programs. The first unit of disciplines, biological resource science, focuses on plant genetics and breeding, crop science, olericulture and floriculture, pomology and postharvest physiology of fruits, animal science, bio-production systems and applied science of food resources. The objectives of this unit are education and research on molecular biology, genetics, physiology and ecology in plants, animals and insects from the viewpoints of practical use, sustainable agriculture production, environmental conservation in natural ecosystems and agro-ecosystems. The second unit of disciplines, biosphere environmental science, focuses on plant parasitic mycology, applied entomology and zoology, environmental soil chemistry, environmental plant biochemistry, forest ecotopology and conservation of regional resources. The objectives of this unit are education and research on comprehensive analysis of biosphere factors and development of their sustainable control and management systems. Also, five professional disciplines of the cooperative graduate school program provide specified topics on plant cell engineering, functional analysis of microorganisms in agro-forest systems, functional physiology of insects, physiology and biochemistry of plant production and conservation genetics.
