Research Statement

  Pest is one of major causes that decrease crop production, and ways such as an agrochemical and introduction of resistance gene have been used to protect crops from pathogens. There, however, are many demerits in the past ways such as an occurrence of agrochemical-resistant strain of pathogens, concerns about safety and influence to an environment of agrochemicals, long time for generation of new cultivar and an occurrence of resistance-breaking strain of pathogens. Thus, it has been desired to develop novel means for pest-management.
   Plants can not move, thus are always surrounded by many microbes. However, very limited microbes infect plants and cause disease, because plants have evolved sophisticated resistance mechanisms. I hope a clarification of plant resistance mechanism leads to the production of novel type of pathogen-resistant plants. In this study, I will focus on the biosynthesis mechanisms of salicylic acid and jasmonic acid, two major signaling molecules that induce plant defense reactions.

My goal

  Tenure track system enabled young scientists to get their own labs. To make my lab comfortable and active, I think it important to do my best in all of study, teaching and management. Although tenure track position is limited for 5 years, I would like to study what I want to do. And also, I would like to teach my knowledge and experiences to students, and I hope this helps them find a fun in science.
