[Abstract]  We recently established an experimental model system for efficient defense-related cell death using tobacco BY-2 cultured cells treated with culture filtrates of the pathogenic bacterium Erwinia carotovora (E. carotovora) (Hirakawa et al., 2015). Applying this experimental system to transgenic BY-2 cells stably expressing the vacuolar membrane marker GFP-VAM3 (Kutsuna and Hasezawa, 2002) allowed us to monitor changes in vacuolar membrane structures including a decrease of transvacuolar strands during cell death (Hirakawa et al., 2015). Our model system can ... [摘要]  我们最近建立了使用烟草BY-2培养细胞的有效防御相关细胞死亡的实验模型系统,所述培养细胞用致病性细菌欧文氏菌(Erwinia carotovora)( E。carotovora (Hirakawa ,,2015)。将该实验系统应用于稳定表达液泡膜标记物GFP-VAM3的转基因BY-2细胞(Kutsuna和Hasezawa,2002),使我们能够监测液泡膜结构的变化,包括细胞死亡期间跨血管链的减少(Hirakawa et al。 al。,2015)。我们的模型系统可以帮助调查细胞器动力学在国防相关的细胞死亡。在这里,我们显示应用 E的协议。 carotovora过滤到BY-2细胞和共聚焦观察液泡膜动力学和随后的细胞死亡。我们使用细胞周期同步的BY-2细胞来有效地监测内陷的液泡膜,例如在我们最近的报告中的跨血管链(Hirakawa等人,2015);然而,我们不描述本文中的细胞周期同步的协议。对于BY-2细胞同步的逐步方案,请参考先前的方案论文(Nagata和Kumagai,1999; Kumagai-Sano等人,2006)。
