    Plant hormones in arbuscular mycorrhizal symbioses (Research in Context)

    Although >80% of species form arbuscular mycorrhizal symbioses, the roles of plant hormones in the associations are still being determined. Foo et al. critically review recent progress in our understanding of the roles of strigolactones, auxin, abscisic acid, ethylene, jasmonic acid and salicylic acid in mycorrhizal symbiosis, and present new evidence for a novel role for […] More

    Mechanisms behind optimal defence patterns (Invited Review)

    The optimal defence hypothesis (ODH) predicts that tissues that contribute most to a plant’s fitness and have the highest probability of being attacked will be the parts best defended. In general, young tissues show stronger induced defence responses and contain higher basal levels of specialized defensive metabolites than other older plant parts. In this review, […] More
