Hundreds of millions of years ago, plants started to colonize the land. But amazingly, they did this without roots. So how on Earth did these early plants feed themselves? It looks like they found some helpful friends: A group of fungi provided them with nutrients from the ground, fossils suggest. Today, the vast majority of plants team up with these so-called mycorrhizal fungi, which live in their roots. In return for nutrients, the plant provides the fungi with carbon in the form of sugar and fats. It’s an age-old symbiosis, and one that continues to fascinate soil scientists. How does the plant-fungi relationship work? Is it love or just a deal? In this episode, Anja learns more from Katie Field, Toby Kiers, Bala Chaudhary and podcast co-producer Matthias Rillig, and explores the world of fungi: How do they travel the world, and what would the world look like from a fungal perspective?
