Abstract
A light-induced auxin-inhibitory substance, indolylacetonitrile (IAN), was isolated from light-grown cabbage (Brassica olearea L.) shoots. T he IAN content in cabbage shoots increased in response to light. Cabba ge hypocotyl elongation is inhibited by 10(-5)M of IAN in 90 min but p romoted after 48 hr. Light-induced growth inhibition is caused by the degradation of 3-indolylmethylglucosnolathe (IMG) to IAN which is, in turn, converted to the growth hormone indole-3-acetic acid (IAA).
