What's New

  • March, 2023
    • New transgenic lines and plasmid vectors have been added in our project. We are waiting for your request.
    • Genome editing constructs for mutating a gene encoding serine racemase.
    • Expression vectors for dominant-negative Sar1.
    • Reporter constructs.
  • December 2022
    • Our plasmid vector for genome editing was used for analyzing gene functions in Starfish. Our resources are always open for the use in organisms other than Ciona. Click here for details.
  • October 2022
    • The transcription factors responsible for the formation of endostyle (the organ suggested to be homologous to vertebrate thyroid gland) were reported. Our knockout vectors were used in this study. Click here for details.
  • July 2022
    • Ciona exhibits metamorphosis after adhesion to substrates with its adhesive organ. The mechanism sensing the mechanical stimuli generated by adhesion, and PKD2 homolog that is involved in this process were reported. Our transgenic lines, reporter constructs and knockout vectors were used in this study. Click here for details.
  • March, 2022
    • Functions of D-serine and serine racemase in Ciona was reported. Our reporter constructs and knockout vectors were used in this study. Click here for details.

About Ciona Intestinalis Transgenic line RESources
