Abstract The distribution of xanthoxin (Xan), was determined in light-grown, 20-d-old pea (Pisum sativum L. cv. Progress No. 9) seedlings. The cis,trans-xanthoxin (c,t-Xan) and the trans,trans-xanthoxin (t,t-Xan) were more abundant in the young leaves and terminal bud; their concentrations in leaves were 2 - 3 times those in internodes of the same nodes. After the onset of red-light-irradiation, the concentration of both Xan isomers in 7-d-old dark-grown pea seedlings increased after a 12-h lag time. The increased level of Xan was greatest in the terminal bud and decreased to lower parts of the seedlings. The ratio of c,t-Xan to t,t-Xan concentration in the seedlings was about 2:3.
