Yoshizawa Lab
Machine-translated · View original
The lab uncovers, starting from genes, how marine microbes live and how they use light.
AboutAbout the lab
Unraveling a vast ecosystem from its genes
The Yoshizawa Lab studies how marine microbes live and what roles they play in ecosystems.
In particular, it focuses on how microbes use sunlight, exploring the relationship between life and light in the setting of the ocean.
The lab combines bioinformatics and molecular biology methods that analyze large volumes of genetic data with field surveys and research cruises.
Using DNA drifting in seawater (environmental DNA), the lab also conducts research that investigates organisms from microbes to large animals all at once.

ResearchResearch themes
Focusing on how marine microbes use light, the lab studies the relationship between life and light and how it changes over time. It combines comprehensive analysis of data such as genomes and metagenomes with field surveys.
*Illustrative imageNovel Ways Microbes Use Light Energy
Using metagenomic analysis and other methods, the lab examines the sequence diversity of proteorhodopsin, which has been found widely in marine bacteria, and how it varies over time and across locations. Through comparative genomics and culture experiments, it also explores the evolution and role of proteorhodopsin.
*Illustrative imageWhy Do Microbes Glow?
Focusing on the color of the light that microbes emit, the lab uses luciferase (the light-emitting enzyme) gene sequences and genomes to study how microbes live by using light and how luciferase has evolved.
*Illustrative imageBioinformatics
The lab analyzes huge datasets such as genomes and metagenomes with information science techniques, in order to find the laws and patterns behind biological phenomena, as well as important genes that are still unknown.
*Illustrative imageGenome Evolution and Ecosystem Mechanisms
By analyzing genome data, gene expression data, and environmental DNA data from new perspectives, the lab explores how the mechanisms of life came about, along with the evolutionary and ecological background behind them.
