[0039] 3.1 Preparation of protoplasts
[0040] Taking 2g of the young leaves of S. rotundum as an example, the specific steps are as follows:
[0041] S1: select the young leaves of Trichophyllum rotifera, wash them with sterile seawater, and raise them temporarily to obtain raw material 1;
[0042] S2: Soak the raw material 1 obtained in S1 in the pretreatment solution to obtain raw material 2;
[0043] S3: Take out the raw material 2 obtained in S2, after absorbing the water, cut the raw material 2 into 0.2cm 2 Add 10mL enzyme solution for enzymolysis to obtain enzymolysis tissue;
[0044] S4: Filter the enzymolyzed tissue obtained in S3 with a 200-mesh sieve to obtain a filtrate;
[0045] S5: Centrifuge the filtrate obtained in S4 at 70×g for 5 min, discard the supernatant, suspend the precipitate with W5 solution, centrifuge, discard the supernatant, and obtain the precipitate;
[0046] S6: Suspend the precipitate obtained in S5 with 2 mL of MMG solution to obtain the ...
