The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.
Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

It is showed that MG132 significantly reduced the germination rate and tube growth. Furthermore, MG132 treatment lead to vacuolization occurred both in tube cytoplasm and generative cell. While DMSO and non-proteasome inhibitor E-64 do not have similar effects. FTIR analysis revealed that MG132 treatment markedly reduced the contents of wall-bound proteins and pectin at the apex of tube.
结果表明：MG132显著抑制青扦花粉萌发和花粉管生长，并导致花粉管形态异常，主要表现为花粉管亚顶端出现液泡化，并且液泡随着培养时间的延长而扩大到整个花粉管，花粉管濒临死亡；而DMSO以及非蛋白酶体抑制剂E-64不产生类似结果；半薄切片结果表明，MG132处理后不仅花粉管细胞质发生液泡化，生殖细胞也发生液泡化；FTIR分析进一步表明，MG132处理后，花粉管顶端的细胞壁蛋白和果胶质含量大幅度下降。
