| 摘 要： | 花粉萌发、花粉管生长是植物有性生殖的重要环节,包含许多复杂的生理过程。微丝是细胞骨架重要组成成分,很多研究表明微丝在花粉萌发、花粉管内原生质流动(Justus et al.,2004)、花粉管顶端生长(Li et al.,2001)等方面具有重要的作用。花粉管

| Abstract: | Microfilament skeleton plays important role during the process of pollen development and pollen tube growth.We observed the distribution of microfilaments in the pollen and pollen tube of Cunninghamia lanceolata by phalloidin labeling fluorescence and confocal laser scanning microscope.The images showed different distribution of microfilaments during pollen germination process.At the early stage of pollen germination,filiform microfilaments occurred in the pollen cytoplasm,and formed thick F-actin bundles a... |
