The response of stomata to ring-substituted indolylacetic acids was written by Thomson, A.;Cox, R. C.;Mansfield, T. A.. And the article was included in New Phytologist in 1988.Name: 2-(5-Chloro-1H-indol-3-yl)acetic acid This article mentions the following:
Indol-3-ylacetic acids with substituents in the aromatic ring (Cl, Cl2, Me) have been synthesized and their effect on stomata on isolated Commelina communis epidermis tested. Unlike IAA which induces stomatal opening, all the substituted acids caused closure. The perception mechanism in the guard cells may therefore involve receptors with high specificity for IAA. The ability of guard cells to discriminate IAA from closely related mols. may be higher than in other cellular systems. There was no synergism between the IAA derivatives and ABA. Also, the percentage stomatal closure induced by CO2 was more or less constant regardless of the concentration of substituted IAAs. In the experiment, the researchers used many compounds, for example, 2-(5-Chloro-1H-indol-3-yl)acetic acid (cas: 1912-45-4Name: 2-(5-Chloro-1H-indol-3-yl)acetic acid).
2-(5-Chloro-1H-indol-3-yl)acetic acid (cas: 1912-45-4) belongs to indole derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Name: 2-(5-Chloro-1H-indol-3-yl)acetic acid
