Brief bio: I have a deep interest in plant molecular biology and biotechnology. Especially, the complex and sophisticated mechanisms of the plant environmental responses are very attractive to me. I have been studying and working in Dr. Kazuko Yamaguchi-Shinozaki’s lab since I was an undergraduate student. The main subject of my research is to elucidate how plants sense and respond to cold stress. I am focusing on molecular mechanisms of cold-inducible expression of the DREB1 genes in Arabidopsis. Previously, I have revealed that Arabidopsis induces the DREB1 expression through two different signaling pathways in response to the cold stress (Kidokoro et al., Plant Cell 2017). In this study, we discovered the regulatory region of the DREB1A promoter, and unexpectedly found that mutation of ICE1 is independent from the DREB1A repression in the ice1-1 mutant plant.
