大豆子叶内酸性磷酸酶活性的超微结构定位

开花后３５～５０ ｄ 期间和萌发早期（播种后４～８ ｄ）的大豆（Ｇｌｙｃｉｎｅｍ ａｘ Ｌ．）种子中，酸性磷酸酶主要分布在子叶细胞中的蛋白体内；在内质网内也检测到酸性磷酸酶活性。此外，在萌发早期的部分子叶细胞的质膜外侧及其细胞壁基质中可见密集的酸性磷酸酶活性；而且在近质膜的胞质中常见到一些富含磷酸铅沉淀的胞质小泡，似与质膜融合

ULTRASTRUCTURAL LOCALIZATION OF ACID PHOSPHATASE ACTIVITY IN SOYBEAN COTYLEDON CELLS

In the cotyledon cells of the developing seeds (35~50 d after flowering) and the early germinating seeds (4~8 d after sowing) of soybean (Glycine max L.), acid phosphatase (APase) activity was mainly deposited in the protein bodies (PB) and in endoplasmic reticulum (ER). In addition, in the early developing cotylendon cells, the prominent reaction product of APase activity was seen along the plasma membrane, in the cell wall and within the vesicles in the cytoplasm adjancent to the plasma membrane. And some of the vesicles seemed to be fused with the plasma membrane.
