英文摘要	利用透射电镜观察了毛竹 (PhyllostachyspubescensMazel)茎纤维发育过程中次生壁的形成过程。纤维发育早期 ,细胞具有较大的细胞核和核仁 ;细胞质浓稠 ,具有核糖体、线粒体和高尔基体等细胞器。随着纤维次生壁的形成 ,细胞壁加厚 ,细胞质变得稀薄 ,内质网和高尔基体的数量明显增加 ,并且两者共同参与了运输小泡的形成 ;在质膜内侧可观察到大量周质微管分布。随着次生壁的进一步加厚及木质化 ,细胞壁形成宽窄间隔排列的多层结构 ;染色质出现凝集并边缘化 ;细胞器膨大、变形甚至解体 ,而周质微管仍然整齐地排列在质膜内侧 ;在质膜和细胞壁之间可观察到大量壁旁体。结果表明 ,内质网、高尔...; Ultrastructural changes in secondary wall formation of Phyllostachys pubescens Mazel fiber were investigated with transmission electron microscopy. Fiber developed initially with the elongation of cells containing ribosomes, mitochondria and Golgi bodies in the dense cytoplasm. During the wall thickening, the number of rough endoplasmic reticulum and Golgi bodies increased apparently. There were two kinds of Golgi vesicles, together with the ones from endoplasmic reticulum formed transport vesicles. Many microtubules were arranged parallel to the long axis of the cell adjacent to the plasmalemma. Along with the further development of fiber, polylamellate structure of the secondary wall appeared, with concurrent agglutination of chromatin in the nucleus, swelling and disintegration of organelles, while cortical microtubules were still arranged neatly against the inner side of plasmalemma. Lomasomes could be observed between the wall and plasmalemma. The results indicated that the organelles, such as Golgi bodies together with small vesicles, rough endoplasmic reticulum and lomasomes, played the key role in the thickening and lignification of the secondary wall of bamboo fiber, though cortical microtubules were correlative with the process as well.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000165203400003&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 8; 10; 1003-1008; 42
