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 由于蘚類植物特殊的生物學結構用農桿菌侵染其原絲體或者莖葉體很難實現轉化,以原生質體作受體是蘚類植物轉化的常用途徑。
