Section outline

      • Comprehensive gene expression analysis using the next-generation sequencer has made it possible to obtain information on genes whose expression increases during sexual reproduction induction by ACC treatment. These genes are expected to function in the formation of sexual germ cells and to contribute to the development of oxidative stress tolerance. Therefore, we plan to analyze the functions of these genes using genome editing, which is currently under development.

      • Based on the findings obtained from Neopyropia yezoensis, we would like to elucidate the reproductive mechanism of other useful red algae. First, we plan to examine whether the effect of ACC can be seen in other red algae.

      • Red algae are considered to be primitive eukaryotes based on the fact that fossils similar in morphology and reproductive organs to existing red algae have been discovered in the strata from more than 1 billion years ago, as well as on the molecular phylogenetic analysis using DNA base sequences. Therefore, we believe that knowledge of the reproductive mechanism of red algae is important not only for contributing to their sustainable production but also for understanding the evolution of the reproductive mechanism of eukaryotes.
