407: Fungus Facilitates Phototroph Feeding

Probably the last episode of the year. See you in the next! This episode: Fungus living inside plants helps them form partnerships with nitrogen-fixing bacteria! Download Episode (5.9 MB, 8.5 minutes) Show notes: Microbe of the episode: Prevotella intermedia Takeaways Plants are very good at acquiring carbon, but they can often use some help with other nutrients. Many form partnerships with microbes such as nitrogen-fixing bacteria or mycorrhizal fungi that can help gather nutrients from the soil better than the plants' own roots. In this study, legume plants could form a partnership with nitrogen-fixing bacteria in its roots, but a fungus living inside the plant could enhance this partnership even more, increasing the amount of nitrogen acquired and influencing the community of microbes around the plant roots in ways favorable to all partners.
