Core Viewpoint - The article discusses the symbiotic relationships between plants and soil microorganisms, specifically focusing on arbuscular mycorrhizal fungi and rhizobia, highlighting their evolutionary significance and molecular mechanisms involved in symbiotic interactions [2][3][4]. Group 1: Symbiotic Relationships - Plants have formed beneficial symbiotic relationships with soil microorganisms, such as nitrogen-fixing bacteria (rhizobia) and nutrient-providing fungi (mycorrhizae) [4]. - Approximately 80% of terrestrial plants have the ability to form mycorrhizal symbiosis, which enhances phosphorus absorption [2]. - Leguminous plants evolved a specific symbiotic system with rhizobia around 60 million years ago, allowing them to fix atmospheric nitrogen into usable forms [2]. Group 2: Common Symbiotic Signaling Pathway (CSSP) - The core genes and regulatory modules governing these two symbiotic systems are highly concentrated in a molecular pathway known as the Common Symbiotic Signaling Pathway (CSSP) [3]. - Understanding the CSSP is crucial for decoding plant-microbe interactions and is considered a theoretical foundation for achieving a green agricultural revolution [3]. Group 3: Molecular Mechanisms - The study published in Science reveals that the Formin family protein SYFO2 mediates the molecular mechanism of rhizobial infection in leguminous plants [4][6]. - SYFO2 is essential for the formation of infection threads, which allow rhizobia to enter host cells, and its transcription is regulated by the specific transcription factor NIN [6]. - The same gene also plays a role in the intracellular infection process of mycorrhizal fungi in legumes and is conserved in non-leguminous crops like tomatoes, indicating potential for engineering nitrogen-fixing capabilities in these crops [6][7]. Group 4: Future Implications - The research elucidates the common mechanisms for establishing symbiosis between bacteria and fungi in plant cells, providing new insights for enhancing or designing crop relationships with beneficial microorganisms [7].
