57Division of Gene ResearchHiroshi OgasawaraAssistant ProfessorUnderstanding the development of biofilms to explore the survival strategies of bacteria based on genomic informationIn the natural environment, many bacterial species form biofilms, and communicate with each other. We are carrying out research to bacteria attached to solid surfaces to understand which genes work in which ways as they develop into biofilms. We believe our research will play a useful role in the future development of medicines targeting bacteria which are harmful to the industrial and medical fields. Assistant Professor Ogasawaratook his current position in 2011 after working as a Research Fellow at the Research Center for Micro-nano Technology and department of Frontier Bioscience in Hosei University. He explores the network of gene expression related to the biolm formation in bacteria. Bacteria, which can adapt to numerous environments, do not always express all of the genes present in their genomes. To clarify the mechanism by which bacteria express express certain genes depending on specic conditions, it will become possible to utilize the capabilities of each bacterium to maximum eect. Outlook for researchWhile many graduates are employed by food companies, they can also pursue careers at phamaceutical and biotech companies.Outlook for students after graduationExamination of the culture conditions that activate gene expression . Bacteria have the ability to quickly regulating of their genes in response to external environmental changes.An electron micrograph of Bacillus subtilis. Many bacteria form biolms.We analyse details of genes involved in the biolm formation of bacteria based on genomic information.Division of Gene ResearchElucidating genome functions for food productionI use DNA sequencing technology that has shown significant technical advancement in recent years to carry out research that contributes to the selective breeding of crops. My lab has used plant materials ranging from rice and mulberries to tropical crops obtained in collaboration with Okinawa Prefecture to carry out research into the efficient breeding of new varieties.Hideo MatsumuraAssociate ProfessorAssociate Professor Matsumura took his current position in January 2010 after working as a senior researcher at the Iwate Biotechnology Research Center. His areas of research include functional genomics for large-scale analysis of gene expression and plant breeding.I hope to utilize genomic information to improve breeding systems so that we can achieve stable food production.Outlook for researchI hope that graduates will pursue careers in research or food-related businesses.Outlook for students after graduationWe collaborate with Okinawa Prefecture to understand the papaya’s sex determination mechanism.A DNA sequencer can be used to sequence isolated genes.
