Substituted indole-3-acetic acid (IAA) derivatives, plant auxins with potential for use as prodrugs in enzyme-prodrug directed cancer therapies, were oxidised with horseradish peroxidase (HRP) and toxicity against V79 Chinese hamster lung fibroblasts was determined. Rate constants for oxidation by HRP compound I were also measured. Halogenated IAAs were found to be the most cytotoxic, with typical
The present invention provides compounds and compositions capable of stimulating plant growth, regeneration of plant cells and tissues, and transformation of plant cells and tissues, comprising mono- and multi-substituted auxinic analogues of indole-3-acetic acid (IAA) comprising substituent groups such as halo-, alkyl-, alkoxy-, acyl-, acylamido- and acyloxy-groups. The invention relates to a method of using such mono- and multi-substituted auxinic analogues of IAA to affect growth, regeneration or transformation in monocotyledonous and dicotyledonous plants, as well as in transgenic plant tissues. The invention also contemplates the use of these auxinic IAA analogues in the presence of other plant growth regulators, such as cytokinin, etc., to enhance plant growth.

Methods for obtaining plants with decreased responses to auxins by reducing exprssion of endogenous MYB77 genes in plants are disclosed. Also disclosed are methods of using plant MYB77 transcriptional promoter sequences to drive expression of heterologous genes in select plant cells at select times in plant development. Methods of obtaining plants with decreased lateral root formation when grown under nutrient deficient conditions by reducing expression of endogenous MYB77 and transgenic plants with reduced expression of endogenous MYB77 genes in are also provided.
