peg structure 中文意思是什麼
peg structure
解釋
釘狀構造-
Because of the special biological structure of bryology, it was very difficult to transfer foreign gene into the protonema or gametophyte by agrobacterium - mediated transformation. protoplasts as acceptor, using direct dna transfer methods such as microprojectile bombardment and peg - mediated transformation is becoming a good way
