摘要: In previous research here, 3,5-diiodo-4-hydroxybenzoic acid (DIHB) was shown to promote the elongation of roots cress (Lepidium sativum) seedlings growing in light, and inhibit auxin-induced production ethylene this tissue. Although DIHB is a cofactor for oxidation indole-3-acetic (IAA) by horse-radish peroxidase, it inhibits decarboxylation [1-14C]IAA segments excised from roots. The inhibition tissue does not, therefore, arise reduction IAA levels. These findings are discussed relation effects on root growth.
