A light-induced auxin-inhibitory substance, indolylacetonitrile (IAN), was isolated from light-grown cabbage ( Brassica olearea L.) shoots. The IAN content in cabbage shoots increased in response to light. Cabbage hypocotyl elongation is inhibited by 10 −5M of IAN in 90 min but promoted after 48 hr....
