Protoplast Cell‐Wall Regeneration: Unlocking New Potential for Genetic Improvement and Tree Breeding

Summary statement The recalcitrance of cell‐wall regeneration in woody plant protoplasts hinders the application of protoplast genetic transformation in woody plant. Establishing an efficient cell‐wall regeneration system for woody plant protoplasts is a key strategy for promoting the application of protoplast transformation in tree genetic improvement and breeding.
