Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.
结果表明,受S素营养胁迫的水稻,其根系及叶片的超微结构均发生了显著的变化:低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀,基粒片层松驰、散乱,细胞器减少,线粒体结构被破坏,根系细胞内几乎没有内含物;S浓度高则会使叶片叶绿体基粒片层致密、浓缩,无规则化,根系细胞发生质壁分离。

Under normal temperature.the Ca2+-ATPase activity was found on the innerside of the PM.on the vacuole envelope and the chloroplast envelope,and theenzyme activity declined upon heat stress.The Ca2+-ATPase activity on the vacuoleenvelope,PM.and the chloroplast envelope in both Ca2+-and oxalate-treated peppermesophyll cells was higher than that in the control under the same condition.TheCa2+-ATPase was also found at the granum lamella,and it was activatedsignificantly by exogenous Ca2+ and oxalate treatments.Under heat stress.the Ca2+-ATPase activity declined slowly in both Ca2+- and oxalate-treated mesophyll cells.But La3+ treatment inhibited the enzyme activity under both normal condition andheat stress.
常温下生长的叶肉细胞,在质膜、液泡膜、叶绿体被膜等处有Ca2+-ATPase活性,热胁迫后酶活性下降;外源Ca2+和草酸预处理对辣椒叶肉细胞各种膜上Ca2+-ATPase活性具有促进作用,特别是定位于液泡膜、质膜和叶绿体被膜上的酶活性明显比对照提高;在叶绿体基粒和基质片层上也有酶活性,并且Ca2+和草酸预处理对该部位上的酶活性激活作用更明显;La3+处理的作用与Ca2+和草酸处理的效果相反。
