Plant Genome Breeding Lab
Machine-translated · View original
A lab that aims to solve social challenges through genome breeding of sorghum.
AboutAbout the lab
Using genome information to breed varieties that answer social challenges
The Plant Genome Breeding Lab uses plant genome information to develop crop varieties suited to solving the challenges of modern society.
The lab regards breeding as a form of "manufacturing" and aims to develop varieties that address challenges such as reducing carbon dioxide, energy, and marine plastic waste.
The main crop is sorghum, and the lab also works on rice.
On the lab's website, it is also introduced under the name "Sazuka Lab."
Key terms
- Sorghum
- A large grass crop native to northeastern Africa. Its seeds, juice, and stems and leaves can all be used.
- Heterosis
- In a broad sense, the term for cases where the first-generation hybrid of a particular cross combination produces high biomass.
- Biorefinery
- Manufacturing and chemical technology that uses sugars or biomass as raw materials, as an alternative to petrochemicals.

The lab focuses on the crop sorghum as a key solution to challenges such as reducing carbon dioxide and creating biorefineries. Its research is end-to-end, from genetic analysis using large-scale genome data to cultivation in the field.
*Illustrative imageGenetic analysis of the mechanism of heterosis
The lab uses large-scale genome data to genetically analyze heterosis, in which the first-generation hybrid of a particular cross combination produces high biomass. It suspects that genes controlling flowering time and internode length are involved, and is testing whether this model is correct.
*Illustrative imageGenes of high-sugar sorghum and a new variety
High-sugar sorghum stores sweet juice in its stem, like sugarcane. The lab identified the location of the high-sugar locus and developed a new variety, "Enryu" (炎龍), that combines high sugar content with high biomass.
