茎叶体 meaning in English

cormus

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
由于藓类植物特殊的生物学结构用农杆菌侵染其原丝体或者茎叶体很难实现转化，以原生质体作受体是藓类植物转化的常用途径。
Here we studied the relationship of various factors and the quality of protoplasts . which maybe could be the basic of moss gene targeting . results showed : inoculated the spores onto diferrent kinds of media , such as ms , benecke and knop , we found that there was no difference when the spores germinated and differentiated into cauliform soon
通过对立碗藓的无菌培养和原生质体操作发现： ( 1 )立碗藓孢朔接种在无菌ms 、 benecke 、 knop培养基上，均可萌发产生原丝体，但不久便分化为茎叶体，很难长期保持其原丝体状态，不同培养基条件下原丝体状态有所不同。
