Abstract
- This article explores the recruitment of arbuscular mycorrhizal (AM) conserved genes for ectomycorrhizal (ECM) symbiosis. ECM symbiosis, which is a more recent form of symbiosis than AM symbiosis, involves the formation of a mantle around the root and an intercellular Hartig net. The study found that ECM host species from the Fagales order maintained the majority of AM-conserved genes, unlike other non-AM hosts. Transcriptome analysis revealed that several of these maintained genes were induced in ECM symbiosis, suggesting that ECM formation recruits AM-derived mechanisms. The study focuses on ECM-only hosts, which are plant species that exclusively engage in ECM symbiosis and have lost the ability to form AM symbiosis. The researchers discovered that ECM-only hosts maintain 64% of the AM-conserved orthologous groups (OGs), highlighting the importance of these genes in ECM symbiosis. They also identified specific genes, such as RAM2, involved in lipid biosynthesis and arbuscule formation in ECM roots. The study suggests that the preservation of AM-conserved genes in ECM-only hosts supports their role in ECM symbiosis. [Extracted from the article]
