The vertical broken lines indicate the incubation times used in examining the effect of X-radiation on the activity of the tryptophan to lAA enzyme system. Figure 6. The in vitro conversion of tryptophan to auxin by cell-free homogenates made from rnung bean seedlings immediately after X-irradiation. The lower curve gives the relative amounts of lAA formed, the upper curve ¥ 5 rbntgens xlO^ The radiation sensitivity in vivo of the tryptophan-I AA enzyme is shown in Figure 6. Unusually low doses of X-rays inhibited the conversion of tryptophan to lAA. An almost identical response to irradiation was shown using the.
