原丝体 meaning in Chinese
protonemata
Examples
- Protonema ( pl . protonemata ) the young bryophyte gametophyte that develops following spore germination . the mature gametophyte plants develop from buds that form at several points along the protonema
原丝体：苔藓植物中直接由孢子萌发形成的结构称为原丝体。原丝体上形成1个或几个芽体，芽体进一步发育为配子体。 - Isolation of protoplasts from different stage of protonema and cauliform revealed that 15 - 17 days protonema was the best material because of the higher protoplasts output . there was less protoplasts when the protonema was over three weeks old
( 4 )通过对原丝体预处理不同时间观察表明酶解前用0 . 02 tween - 80预处理30min能明显提高原生质体的产量。 - 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。
