The invention discloses a method for efficiently converting a
gene module and line for a rice leaf sheath
protoplast, and relates to a
conversion method of the rice leaf sheath
protoplast. The methodcomprises the steps of adding an MMg solution to the rice leaf sheath
protoplast to obtain a rice leaf sheath protoplast suspension; adding
plasmid and a
polyethylene glycol-
calcium solution of whichthe percentage by
mass is 40% to the rice leaf sheath protoplast suspension, performing uniform mixing, and performing standing; and adding a W5 solution, performing uniform mixing, performing
centrifugation, removing supernatant, performing suspension once again and
precipitation on the W5 solution, performing
centrifugation, removing supernatant, adding carbenicillin, performing uniform mixing,and performing culturing to complete transformation of the protoplast. According to the
conversion method of the rice leaf sheath protoplast, preparation,
plasmid concentration, conversion time and the like of the PEG solution are adjusted, so that the conversion efficiency is improved to 80%, intelligent reformation devices can exert functions in 80% of
plant cells, available data can be providedfor research on functions of the devices at the initial stage, and convenience is provided for research on functions of the intelligent reformation devices for crops at the later stage.
