This study shows how ethylene biosynthesis shifts spatially during nodule initiation in Medicago truncatula, with specific ACS genes regulating infection and nodule formation.

The paper investigates auxin and tryptophan responses in the alga Penium margaritaceum, finding shared physiological and transcriptomic responses between auxin and tryptophan.

This study shows that C-terminally encoded peptides (CEPs) and their receptor CRA2 regulate both root nodulation and arbuscular mycorrhizal symbiosis (AMS) in legumes by controlling phosphate homeostasis and strigolactone biosynthesis.

This study shows GA and BR are necessary for tomato stem elongation under low R:FR light, with IAA enhancing GA's effect.

This study shows nitrate inhibits nodule formation in Medicago truncatula by reducing ACC SYNTHASE 10 expression, linking ethylene biosynthesis to nitrate's regulatory effect on nodulation.

The paper shows that non-nodulating relatives of Parasponia lost key symbiosis genes, challenging the hypothesis that nodulation evolved independently multiple times.
