Plant hormones in arbuscular mycorrhizal symbioses: an emerging role for gibb…

† Background and Aims: Arbuscular mycorrhizal symbioses are important for nutrient acquisition in >80% of terrestrial plants. Recently there have been major breakthroughs in understanding the signals that regulate colonization by the fungus, but the roles of the known plant hormones are still emerging. Here our understanding of the roles of abscisic acid, ethylene, auxin, strigolactones, sal…
