Autophagic processes involved in the formation and enlargement of plant vacuoles

我们研究了植物液泡的形成和扩大与自噬过程之间的关系。我们已经表明，大自噬途径有助于扩大预先存在的液泡在拟南芥根细胞。另一方面，中央空泡的前体结构似乎是通过自噬过程形成的，这与传统的大自噬不同。我们已经发现，这样一个新的自噬过程中发挥的作用，在小原生质体，其中中央液泡已被删除的液泡的产生。

We have examined relationship between the formation and enlargement of plant vacuole and autophagic processes. We have shown that the macroautophagy pathway contributes to the enlargement of pre-existing vacuoles in Arabidopsis root cells. On the other hand, the precursor structure of the central vacuole seems to be formed through an autophagic process that is different from conventional macroautophagy. We have revealed that such a novel autophagic process play a role in the generation of vacuoles in miniprotoplasts, in which the central vacuole has been removed.
