rpc00111: Arabidopsis thaliana YG1-c callus culture


  • Components

    • A 9-cm plastic Petri dish, containing cells placed on semi-solid medium

  • Notice

    • Subculture the cells to fresh medium immediately after arrival.

    • Do not store the cell culture in a refrigerator and a freezer.

    • Maintain aseptic conditions of the cell culture, and work in a laminar flow cabinet.

  • Method

    • Culture medium: mLS medium, 0.2 mg/L 2,4-D, 0.4% (w/v) gellan gum, pH 5.8 (medium no. 71)

    • Culture conditions: 27°C, dark

    • Subculture: 14–21-day intervals

  • Citation of cell line

    When results obtained by using this cell line are published in a scientific journal, it should be cited in the following manner: “Arabidopsis thaliana YG1-c cell line (rpc00111) was provided by the RIKEN BRC through the National BioResource Project of the MEXT, Japan.”


Arabidopsis YG1-c cell line was established by subculturing the YG1 suspension culture on a semi-solid culture medium. The parent YG1 cell line (rpc00050) was derived from a seedling of Arabidopsis thaliana (L.) Heynh. accession Columbia (Nishikiori et al. 2011 [1], Yoshikawa et al. 2021 [2]). The YG1-c cells are grown on a modified Linsmaier and Skoog (mLS) medium supplemented with 0.2 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D), and solidified with 0.4% (w/v) gellan gum, pH 5.8. Our YG1-c cell culture has been maintained in the dark at 27°C and subcultured at 14–21-day intervals.

Preparation of mLS medium (medium no. 71)

  1. Dissolve the following chemicals in approximately 800 mL of distilled water.



    MS salt mix

    1 bag (1 L)


    30 g

  2. Add following stock solutions, and fill up to approximately 950 mL with distilled water.

    Volume (mL)





    2,4-D (0.2 mg/mL)


  3. Adjust the pH of the solution to 5.8 with KOH (1 N), and fill up to 1 L with distilled water.

  4. Add 4 g of gellan gum to the medium.

  5. Autoclave the medium at 121°C for 20 min.

  6. Pour 30 mL of the medium into a 9-cm Petri dish.


  1. Pick up an appropriate amount of callus cells from a 14–21-day-old culture with a forceps and place the cells onto fresh mLS medium.

  2. Seal the Petri dishes using two rounds of surgical tape.

  3. Incubate cell cultures under the dark condition at 27°C.


  • We send YG1-c cells on semi-solid mLS medium in a 9-cm disposable Petri dish. The cells should be subcultured to fresh mLS medium immediately after arrival.

  • In order to maintain YG1-c callus culture stably, it is essential to observe the growth of cells carefully. Because proliferation of YG1-c cells is affected by culture conditions, such as a room temperature, aeration conditions of the culture and so on, an amount of cells transferred to fresh medium and the subculture intervals may vary from one lab to another. We usually inoculate nine pieces of YG1-c callus (about 3-mm in diameter) on 30 mL of mLS medium in a 9-cm Petri dish, and culture them for 14–21 days.

  • Suspension cultures can be derived from YU-1-c callus cultures by subculturing them into a liquid culture medium. The suspension culture method is the same as rpc00050 YG1.
