7-Methyl-DL-tryptophan
Based on 1 Customer Validation
7-Methyl-DL-tryptophan (7-Methyltryptophan) is an anthranilate synthase inhibitor that inhibits tryptophan biosynthesis. 7-Methyl-DL-tryptophan is also a tryptophan analog. 7-Methyl-DL-tryptophan can cause growth inhibition in tobacco, whereas a feedback-insensitive anthranilate synthase confers resistance and can be used as a selective agent to recover transgenic tobacco plants expressing this enzyme.

Biological Activity
Description
In Vitro
7-Methyl-DL-tryptophan (75 µM; 1-6 weeks) completely inhibited the growth of wild-type tobacco seedlings at 3 weeks, whereas ASTIV seedlings maintained a 90-98% survival rate within 6 weeks[1].
7-Methyl-DL-tryptophan (300 µM; 6 weeks) selection from 135 leaf discs yielded ten resistant tobacco lines, with a transformation efficiency of 7.4%[1].
Tobacco lines screened with 7-Methyl-DL-tryptophan (75 µM; 21 days) showed a resistance segregation ratio close to 3:1 in the T1 progeny on 75 µM 7-Methyl-DL-tryptophan, and homozygous T2 lines displayed 100% germination/growth on 75 µM 7-Methyl-DL-tryptophan[1].
