Environmental factors and microbe-microbe interactions drive the structure of the core microbiota of terrestrial microalgae
Plants and other photosynthetic organisms interact with their environment and surrounding microbiota through specialized associations. A global core microbiota has been proposed at high taxonomic levels, such as the order level. However, it remains unclear which environmental factors and how microbe-microbe interactions drive variation of this core microbiota at lower taxonomic resolution. Here,…
Environmental influences and complex microbe-microbe interactions play a significant role in shaping the core microbiota of terrestrial microalgae. While broader environmental factors have a limited impact on the overall abundance of these core orders, they do influence the core microbiota at a more granular level. Microbial interactions, specifically within the core microbiota, are crucial in determining the structure and stability of these communities.
By analyzing data from 141 sites in southwestern France, researchers have identified seven bacterial and five fungal orders as the global core microbiota of terrestrial photosynthetic organisms. These findings emphasize the importance of considering both environmental context and microbial interactions when studying the composition of the core microbiota associated with photosynthetic organisms.
