Plants as sessile organisms are constantly under attack by herbivores, rough environmental situations, or mechanical pressure. These challenges often lead to the induction of wounds or destruction of already specified and developed tissues. Additionally, wounding makes plants vulnerable to invasion by pathogens, which is why wound signalling often triggers specific defence responses. To stay competitive or, eventually, survive under these circumstances, plants need to regenerate efficiently, which in rigid, tissue migration-incompatible plant tissues requires post-embryonic patterning and organogenesis. Now, several studies used laser-assisted single cell ablation in the Arabidopsis root tip as a minimal wounding proxy. Here, we discuss their findings and put them into context of a broader spectrum of wound signalling, pathogen responses and tissue as well as organ regeneration.

基于目标细胞消融的洞察力,有助于伤口愈合和修复模式。

作为固着生物的植物经常受到食草动物,恶劣的环境状况或机械压力的攻击。这些挑战通常导致伤口的诱导或已经指定和发育的组织的破坏。此外,伤口使植物易受病原体侵袭,这就是为什么伤口信号通常触发特定的防御反应的原因。为了在这些情况下保持竞争力或最终生存,植物需要有效地再生,而在刚性,组织迁移不相容的植物组织中,需要胚胎后的模式和器官发生。现在,几项研究在拟南芥的根尖使用激光辅助单细胞消融作为最小的损伤替代。在这里,我们讨论了他们的发现,并将它们置于更广泛的伤口信号传导环境中,
