Plant Resource Genomics Lab
Machine-translated · View original
The lab searches genomes for genes involved in plant stress tolerance.
AboutAbout the lab
The right plant in the right place, from its genes
The Plant Resource Genomics Lab studies the characteristics of various plants, especially stress tolerance and the genes involved in it.
The lab aims to use plants wisely for sustainable production that requires little labor or resources.
Using pearl millet, asparagus, Arabidopsis thaliana, and other plants as materials, the lab investigates genes with genomics and molecular biology methods, and also grows the plants in fields to evaluate their traits.
The lab belongs to the Asian Natural Environmental Science Center and is located within the Institute for Sustainable Agro-ecosystem Services in Nishitokyo City.
Key terms
- Stress tolerance
- The ability of plants to survive and grow in harsh environments such as drought, salt, and heat
- Genomics
- A research field that reads and analyzes an organism's entire set of genetic information (the genome) as a whole
- Transcription factor
- A protein that switches other genes on or off and thereby regulates their activity
- Dioecy
- A plant trait in which individual plants are divided into those bearing only male flowers and those bearing only female flowers

View More ↗ResearchResearch themes
The lab aims to clarify various plant traits, especially stress tolerance, identify the genes involved, and advance the development and use of the right plant in the right place. It uses methods such as gene cloning, genome sequencing, and genome editing, and also conducts field cultivation and evaluation.
*Illustrative imagePearl millet genes
The lab studies genes of pearl millet, a cereal crop highly tolerant of drought and heat, in collaboration with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in India. It tests the effects of genes involved in days to flowering and yield, aiming to improve crop growth and yield.
*Illustrative imageGenes for sex and color in asparagus
Asparagus is a dioecious crop, and growing only male plants is better suited to cultivation. The lab studies the function of the transcription factor MYB35, a candidate gene for sex determination, and also investigates the causal gene in varieties that rarely accumulate the purple pigment (anthocyanin).
*Illustrative imageVIP1 in Arabidopsis thaliana
The Arabidopsis thaliana transcription factor VIP1 temporarily accumulates in the nucleus when cells are exposed to low osmotic pressure or physical stimuli such as touch. The lab examines the roles of VIP1, its related genes, and the mechanisms that regulate them by creating plants lacking these genes.
