Effect of the substitution of a carboxymethyl group for a hydrogen atom on position 1 or 2 of the indole nucleus, on the growth of wheat coleoptile segments grown for 20 hrs

Effect of the substitution of a carboxymethyl group for a hydrogen atom on position 1 or 2 of the indole nucleus, on the growth of wheat coleoptile segments grown for 20 hrs. Comparison with IAA and indole. Dubouchet, Jacques; Seguin, Alain; Vebrel, Joel; Laude, Bernard (Lab. Physiol. Veg., Inst. Sci. Nat., Besancon 25030, Fr.). C. R. Acad. Sci., Ser. 3, 299(19), 819-22 (French) 1984. CODEN: CRASEV. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Effect of indol-1-yl-acetic acid [24297-59-4] and indol-2-yl-acetic acid [32588-36-6] on the elongation of dark or light grown wheat coleoptile segments was investigated. Comparative bioassays were carried out with indole [120-72-9] and indol-3-yl-acetic acid [87-51-4]. The substitution of a CH2COOH group for a H atom on position 1 or 2 of the indole nucleus makes the mol. able to promote auxin activity. The importance of the increase in cell length depends on the structure and on the concn. of the mol.

ISSN: 0584-8539. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 27 IR and NMR spectroscopy showed the structural differences between 1-, 2-, and 3-indolylacetic acids (I-III, resp.). The conventional mass spectra of I-III and their Me esters were very similar; however, the Me esters could be differentiated by MIKE and CID-MIKE techniques on the mol. ion. .
