The lab takes on genome editing of plant organelles and sorghum genes.
AboutAbout the lab
Understanding plants from the perspective of genes
The Plant Molecular Genetics Lab conducts research that deepens our understanding of plants through analysis at the microscopic level of genes.
Among plant organelles such as chloroplasts and mitochondria, the lab studies how mitochondria are maintained through fission and fusion.
The lab also focuses on genome editing research that targets and rewrites the unique genomes carried by organelles.
The lab is also studying the genes that determine agriculturally important traits in sorghum, a cereal crop.
Key terms
- Organelle
- A small structure within a cell that carries out a specific function, such as chloroplasts and mitochondria
- Genome editing
- A technology that cuts or rewrites sequences at targeted locations in a genome to alter how genes function
- Biomass crop
- A crop grown so that the plant itself can be used as a raw material for fuel or other resources

ResearchResearch themes
The lab conducts research aimed at deepening understanding of plants through analysis at the microscopic level of genes. It works on research into plant organelles (chloroplasts and mitochondria) and research into the genes that determine agricultural traits in sorghum, a cereal crop.
*Illustrative imageResearch on Plant Organelles
Chloroplasts and mitochondria are intracellular organelles responsible for processes such as respiration and photosynthesis. The lab investigates how mitochondria are maintained through fission and fusion, and places particular emphasis on genome editing of the unique genomes that organelles carry.
*Illustrative imageGenes That Determine Agricultural Traits in Sorghum
Sorghum is one of the world's five major cereal crops, yet it still has considerable room for improvement. For traits that are important when it is used as a biomass crop, the lab aims to isolate the causal genes, clarify their functions, and apply them to breeding.
