水稻单209矮品种的叶片感染白叶枯病菌后,感病细胞超微结构有显著变化。叶绿体膜。系统降解,线粒体肿胀、脊和基质异常,并在感病细孢中常可观察到内陷的质膜和膜系网络结构,此外,在胞质中大量出现颗粒状和纤维状物质。这些物质可能具有抗病功能或者是抗病反应的产物。 The ultrastructural changes of susceptible cells were significantly affected by leaves of the dwarf rice variety 209 single blight. Chloroplast membrane. Systematic degradation, swelling of mitochondria, abnormal ridges and matrices, and often invaginated plasma membrane and membranous network structures were observed in susceptible spores. In addition, a large number of granular and fibrous substances appeared in the cytoplasm. These substances may have disease resistance or are the product of disease-fighting reactions.
