Endoplasmic reticulum (ER) is the most multitalented and adaptable compartment in plant cells. Recently, a wound-inducible organelle, which is derived from ER and designated the ER body, was found in Arabidopsis. Wounding and methyl jasmonate induce many ER bodies in rosette leaves, which have no ER bodies under normal conditions. In contrast, tender seedlings have a wide distribution of the ER bodies especially in all the epidermal cells, which are easily stressed by the external environment. The ER bodies play a role in a novel and unique type of endomembrane system that is involved in the response of plant cells to environmental stress and wounding.

源自内质网的可诱导伤口的细胞器：抗环境胁迫的植物策略？

内质网（ER）是植物细胞中功能最丰富且适应性最强的区域。最近，在拟南芥中发现了一种可诱导伤口的细胞器，该细胞器起源于ER，被命名为ER体。伤口和茉莉酸甲酯会在莲座叶中诱导许多ER体，而在正常条件下则没有ER体。相比之下，嫩苗的ER体分布广泛，尤其是在所有表皮细胞中，这很容易受到外部环境的压力。ER体在新型独特的内膜系统中起作用，该系统参与植物细胞对环境胁迫和伤害的反应。
