Outline

This project aims to develop novel techniques to duplicate any regions in the genome, apply selection pressure to any genomic sequences, and introduce mutations throughout the target regions, by fully exploiting CRISPR-Cas system, two-hybrid system, and base editing enzymes in the baker’s yeast as a model system. We will combine these techniques to take a constructive approach to deepen the understanding of adaptive evolution by gene duplication. These techniques will provide an important step toward constraint-free design of evolvable genomes.

Wataru Iwasaki

Bioinformatics for predicting new functions in DNA sequence space

The University of Tokyo

Outline

In the era of genome synthesis, new bioinformatic technologies for predicting new functions in DNA sequence space are needed. The aim of this project to develop such bioinformatic technologies to take full advantage of ever-increasing sequence data. Development of new biotechnological tools for modifying and controlling genomes is also envisioned.

Takehiko Kobayashi

Construction of gene amplification system and chromosomal vector

Outline

We develop a gene amplification system that increases any genes. Moreover, using the amplification system, we make a chromosomal vector that clones ~100 genes. This vector makes it possible to construct heterogeneous physiological systems and to face establishment of artificial cells in the future.

Outline

This project pursues novel technology of autonomous artificial cell reactors. We develop chemical microreactor systems that are capable to actively condense and hold biological macromolecules such as DNA and proteins and also to undergo cell-like morphological changes as growth, fission and division. We also develop new chemical/biological tool boxes in order to newly confer and enhance the functionalities of artificial cell reactors. By implementing cell-free systems for gene-replication and gene-expression in artificial cell reactors, we aim to create artificial cells with the capability of autonomous self-replication.

Outline

JCVI-syn3.0B is a synthetic bacterium established in 2016 on the basis of mycoplasma. Its genome consists only of genes essential for growth. In this study, we will transfer and express various genes into this synthetic bacterium, and experimentally reproduce events which happened in the evolution from primitive cells to eukaryotes, the acquisition of abilities such as motility, cell wall formation, DNA segregation, and membrane remodeling. Furthermore, new cell construction will be performed by free design of the cells.

Outline

For applications of long-chain DNA to cell biology, delivery methods to cells are limited since long-chain DNA has both a bulky 3D structure and a high fragility to the physical stimuli. In this study, we will combine the novel bubble injector and the micro-structure to develop the new long-chain DNA delivery system.
