🧬🌱 REVIEW 🌱🧬 Ferreras-Garrucho et al. explore recent methodological advancements in single cell technologies to unravel the spatio-temporal dynamics of arbuscular mycorrhizal symbiosis, focusing on cell-type-specific plant and fungal transcriptomes. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Fig. 1 (shortened, full legend in paper): Spatio-temporal dynamics of arbuscular mycorrhizal symbiosis at diverging plant scales. (A) Zoomed-in general root colonised by arbuscular mycorrhizal fungi (AMF) is shown, showcasing the extra- and intraradical fungal structures and their spatial localisation within the root layers, as well as the asynchronous nature of the interaction, as distinct colonisation stages are present in the same root. (B) Detail of a general root with exodermis, sclerenchyma, and multiple cortical layers, highlighting the longitudinal organisation of the root zones from root cap to differentiation zone. Darker colouring of the exodermis, endodermis, sclerenchyma, and xylem indicates their increasing level of suberisation, lignification, and/or formation of Casparian strips going from the meristem to the differentiation zone.
