Conversion of isatin to isatate as related to growth promotion in Avena coleoptile and pisum stem sections.
Isatin, (indole 2,3-dione), which promotes elongation of Pisum stem sections at concentrations exceeding 0.1 mm, promotes elongation of Avena coleoptile sections only at higher concentrations, exceeding 1 mm. Aged isatin solutions are more active than fresh solutions, due to the slow, spontaneous conversion to isatate (o-aminophenylglyoxylate). A concentration of 0.1 mm aged isatin is as active in Avena coleoptile sections as in peas. Isatate has been independently synthesized and its auxin activity in both Avena coleoptile and Pisum stem sections confirmed. The synthetic isatate is more effective than isatin in both systems. This suggests that the auxin activity of isatin is due to its conversion to isatate.
