Plant growth regulators from the edible mushroom Leccinum extremiorientale
TL;DR: Two compounds were isolated from the edible mushroom Leccinum extremiorientale and in the bioassay examining plant growth regulatory activity using lettuce, compound 1 promoted the root growth as low as 100 nmol/paper dose-dependently and inhibited the hypocotyl growth at 1000 nml/paper.
