56Department of Applied BiologyCreating new plants based on knowledge of basic plant science in order to contribute to the development of a sustainable societyI investigate the molecular mechanisms by means of which plants protect themselves from salinity stress (high-salt environments) using the experimental methods of molecular biology, molecular genetics, and plant physiology. I hope to develop innovative technology to generate salt-resistant crops in order to increase agricultural yields in salt-affected areas.Associate Professor Horie took his current position in 2010 after working as a researcher at the University of California, San Diego, and as an assistant professor on special contract with the Institute of Plant Science and Resources at Okayama University. His research centers on the basic molecular physiology of plants and plant genetic and cellular engineering based on it.I expect that my lab’s research could become an important element in avoiding food and energy shortages that are expected in the near future if we can apply knowledge obtained from basic plant science to breed salt-tolerant plants.Outlook for researchMany of the students in my lab choose to pursue careers with companies whose work involves plants. Graduates also tend to be interested in working for companies that develop distinctive environmental technologies or in becoming teachers.Outlook for students after graduationWe analyze the target Na+ transporter that is essential for plant salt tolerance in the oocyte expression system of Xenopus laevis. We are attempting to produce mutagenized Na+ transporters, which we expect to increase the salt tolerance of the host plants.My lab focuses on rice and plants in the genius Arabidopsis for molecular physiological studies using wild-type and Na+ transporter-mutant plants. The picture shows an example of a hydroponic culture of rice plants.Tomoaki HorieAssociate ProfessorDepartment of Applied BiologyUtilizing Agrobacterium tumefaciens, which carries out genetic engineering on its ownI am carrying out research on how to use A. tumefaciens, which has the ability to insert its own DNA into the chromosomes of plants, to develop DNA insertion methods for numerous crops; research to infect plants with A. tumefaciens to create useful substances; and research to alter A. tumefaciens through genetic engineering to give the bacterium new capabilities.Associate Professor Nogawa took his current position after working as an assistant professor at the Nagaoka University of Technology and as an assistant professor in the Faculty of Textile Science and Technology at Shinshu University. His principal areas of research are genetic engineering and applied microbiology focusing on plants and microorganisms.In addition to creating plants that do not need pesticides, we can create raw materials for industry and pharmaceuticals. Through the use of genetically modied plants, these substances will be created using only solar energy and CO2.Outlook for researchWhile many graduates are employed by food companies, others work at computer and chemical companies and as public ocials, for example as plant protection ocers.Outlook for students after graduationBranching in this mulberry tree has been increased from a state of apical dominance through the increase in expression of cytokinin due to genetic modication.A.tumefaciens is injected into a turnip.DNA from A. tumefaciens has caused this turnip to turn green.Masahiro NogawaAssociate ProfessorTransformantUntransformant
