Abstract

The specific inhibitors of cytoskeleton and histochemical stain were used to investigate formation of cell polarization during the early development of conchospores in Pyropia haitanensis. Polarized conchospores w ere observed tw ice: Anterior-posterior axis is formed in migrating conchospores. After migration,conchospores adhere to the substratum and then apical-basal axis is established. Meanw hile,composition of mucilage around conchospores w as studied,and acidic polysaccharides and sulfated polysaccharides w ere found at the rear end in migrating conchospores and basal portion of up-righted conchospores. These results indicate that mucilage is involved in formation and maintenance of the cell polarization in conchospores. Inhibitors of cytoskeleton prevented the released conchospores from germinating through disturbing the anterior-posterior axis formed in migrating conchospores. It w as found that they also affected the establishment of apical-basal axis for abnormal germinations in the inhibitors-treated migrated conchospores. These results indicate that cytoskeleton and mucilage are involved constantly in tw ice cell polarization formation of conchospores in P. haitanensis.

海棠螺孢子细胞极化过程中的细胞骨架和黏液

利用细胞骨架特异性抑制剂和组织化学染色研究了海檀焦皮螺孢子发育早期细胞极化的形成。在冰上观察到两极分化的螺孢子:在迁移的螺孢子中形成了前后轴。贝壳孢子迁移后附着在基质上，形成顶基轴。同时，研究了螺孢子周围黏液的组成，在迁移螺孢子的后端和直立螺孢子的基部发现了酸性多糖和硫酸多糖。这些结果表明，黏液参与了螺孢子细胞极化的形成和维持。细胞骨架抑制剂通过干扰螺孢子迁移过程中形成的前后轴来阻止释放螺孢子的萌发。研究发现，它们还影响了经抑制剂处理的迁移螺孢子异常萌发的顶基轴的建立。这些结果表明，海棠螺孢子的冰细胞极化形成过程中持续参与了细胞骨架和粘液的形成。
