| 摘 要： | 以枯斑三生烟为材料,用细胞化学沉淀法测定了TMV侵染对烟草叶片细胞中Ca^2＋分布的影响,并探讨了Ca^2＋在植物抗病性中的作用。结果发现,枯斑三生烟健叶中的Ca^2＋主要分布于细胞间隙和液泡,接种TMV后,细胞间隙中的Ca^2＋逐渐向细胞内转移,在接种后48h,Ca^2＋主要分布于过敏性坏死细胞和近坏死区细胞,远坏死区细胞间隙缺Ca^2＋;以后由于枯斑停止发展,在接种后96h远坏死区细胞逐渐恢复钙稳态。

| Abstract: | Tobacco "Samsun NN" was used to examine the effects of TMV innoculation on the distribution of soluble Ca~(2+) in tobacco leaves via potassium pyruantimonate technique. The results indicated that the Ca~(2+) in healthy leaves mainly distributed in intercellular spaces and vacuoles. After innoculated with TMV, intercellular Ca~(2+) transported into cytosal and accumulated only in and around lesions of hypersensitive reaction site. Later on, as lesions stopped extending, the Ca~(2+) a bit far from the lesions would gradually return to normal state. |
