Abstract: Arbuscular mycorrhizal symbiosis (AMS) arose in land plants more than 400 million years ago, perhaps acting as a major contributor to plant terrestrialization. The ability to engage in AMS is evolutionarily conserved across most clades of extant land plants, including early diverging bryophytes. Despite its broad taxonomic distribution, little is known about the molecular components that underpin AMS in early diverging land plants as the mechanisms regulating the symbiosis were primarily characterized in angio… Show more

“…The fourth argument in favor of AM symbiosis as a synapomorphy of the embryophytes has been obtained by comparing the transcriptomic reprograming induced by AM fungi colonization across plant species. Originally conducted by comparing the expression of well-known genes from the angiosperms with their orthologs from the liverwort Lunularia cruciata ( Delaux et al, 2015 ), these comparisons were recently expanded to genome-wide analyses between Marchantia paleacea and multiple angiosperms ( Sgroi and Paszkowski, 2020 ; Rich et al, 2021 ). These independent analyses identified multiple molecular functions and biological processes such as the carbohydrate metabolism, upregulated in most, if not all, of the investigated species ( Rich et al, 2021 ).…”

“…As for angiosperms, measurement of the total phosphorus and nitrogen content in tissues of M. paleacea colonized or not by AM fungi revealed a significant improvement of the plant nutrient uptake through symbiosis ( Humphreys et al, 2010 ). In addition, the phosphate and ammonium transporters found regulated during AM symbiosis in L. cruciata and M. paleacea belong to the same gene families as the angiosperm symbiotic transporters, although the phosphate transporter clusters in a different subclade ( Delaux et al, 2015 ; Sgroi and Paszkowski, 2020 ; Rich et al, 2021 ). The homology of these processes across embryophytes can now be tested with the reverse-genetic tools available for M. paleacea .…”
