I am a plant molecular biologist with a strong interest in how organelle genomes shape plant reproduction and adaptation. After completing my bachelor’s, master’s, and doctoral studies at the University of Tsukuba, I joined Tohoku University as a research assistant professor in the Graduate School of Agricultural Science. My research centers on cytoplasmic male sterility (CMS) and its restoration mechanisms, particularly in tomato. During my doctoral work, I identified the mitochondrial gene orf137 as the cause of CMS through mitochondrial genome editing, and more recently, I have been investigating how nuclear-encoded factors such as mitochondrial RNA polymerases contribute to fertility restoration. By combining genome editing, organelle genome assembly, and transcriptome analysis, I aim to unravel the complex interactions between the nucleus and mitochondria that govern plant fertility.
