Episode 384 - Plants regenerating and fighting off invaders

June 22, 2020

How do plants manage to recover from damage or fungal attacks? What happens when you shoot a laser at some cress? Studying the way plants respond to damage helps us understand their regeneration methods. Plant cells can regenerate to recover from damage, but what controls this process? Fighting off a fungal invasion means an arms race between plants and fungus. Plants like cabbage use a special mustard oil bomb to fight back against fungal invaders. Fungal invaders like white mold can render even the most sophisticate plant defences useless.
