Metabolic Profiling of Arabidopsis Thaliana Reveals Herbicide- and Allelochemical-Dependent Alterations Before They Become Apparent in Plant Growth

Isoflavonoids can inhibit the growth of certain plants and are produced by leguminous species such as clover used for cover cropping and weed suppression. Isoflavonoids have, therefore, been suspected of playing a part in chemical weed suppression by legumes. The effects of biochanin A, an isoflavone, and catechin, a phytotoxic flavanol on the growth of Arabidopsis thaliana were studied in a cultivation assay and compared to the effect of the...
