[Abstract]  Cell suspension cultures have been studied for decades to produce natural molecules. However, the difficulty in generating stably transformed cell lines has limited their use to produce high value chemicals reproducibly and in elevated quantities.

In this protocol, a method to stably transform and maintain Arabidopsis cell suspension cultures is devised and presented in detail. Arabidopsis cell cultures were directly transformed with A. tumefaciens for the overexpression of the CORONATINE INSENSITIVE 1 (COI1) jasmonate receptor. Cell cultures were established after transformation and continuously maintained and tested for the overexpression of COI1. The protocol was also previously used to silence Arabidopsis peroxidases and allows for long ...
[摘要]  [摘要]细胞悬浮培养已经研究了数十年,以生产天然分子。然而,产生稳定转化的细胞系的困难限制了它们用于可再现地和高产量地生产高价值化学品的用途。

在该协议中,设计并详细介绍了稳定转化和维持拟南芥细胞悬浮培养物的方法。直接用根癌农杆菌转化拟南芥细胞培养物,以过量表达可乐宁不敏感1(COI1)茉莉酸酯受体。转化后建立细胞培养物,并连续保持并测试COI1的过表达。该协议以前也曾用于沉默拟南芥过氧化物酶,并允许长期维持转化细胞。提供了在液体和固体培养基中培养维持的详细信息,以及蛋白质表达的证据来证实转化。

所描述的系统为合成生物学研究独立于发育控制的信号传递并获得生物技术和医学领域感兴趣的代谢物提供了强大的工具。

[背景]植物细胞悬浮培养为植物次生代谢产物的生产和去分化组织的研究提供了可行的替代方法(Wu和Ge,2004; Lee等,2010)。数十年来,人们对它们的使用兴趣不断提高,因为它们可以为人类使用的高价值生物技术产品提供连续生产系统。有各种各样的细胞培养物可产生大量具有商业和工业意义的次级代谢产物,例如花青素,甜菜碱,调味剂,甜菊苷等(Rao和Ravishankar,2002)。
