traumatic acid

… In 1927, B. Wehnelt, a student of Haberland, found a biological method to quantify this hormone by removing seeds from immature kidney bean pods and applying a sample liquid to the inside of the pod, which then rose up. Since then, research into isolating and identifying the substance has progressed rapidly. Using this method, J. English and others from the United States discovered that the wound hormone was present in the pods themselves, which were used as materials for this study. In 1939, they isolated the substance as crystals and identified it as traumatic acid (⊿ 1- decene-1,10-dicarboxylic acid, HOOC-CH=CH-(CH 2 ) 8 -COOH). Its action is promoted by glutamic acid, phosphate, and sucrose, but it has no effect other than inducing cell division when wounded, and does not induce cell division under tissue culture conditions. …
