The ultrastructural features of wheat interacting with stripe rust fungus were studied by using typical wheat cultivars of high - temperature resistance to rust as experimental material 摘要用典型小麦高温抗?性品种作试材，研究了它们与条?菌互作的超微结构。

The higher concentration of extracellular calcium could influent the stability of microtubules in protoplast . mts in the protoplasts would depolymerize when the extracellular calcium concentration was rising up to lommoi / l . the intercellular washing fluid ( iwf ) of wheat - leaf rust fungus interaction which contains elicitor were used as stimulator to interact with the protoplast of cv 试验结果表明，在小麦叶肉细胞原生质体中，微管骨架呈网络状分布于整个细胞质中；胞外较高的ca ~ ( 2 + )浓度对微管骨架的稳定性有影响，在本试验系统中当胞外ca ~ ( 2 + )达到10mmol / l时，微管骨架即开始发生解聚。
