    Biosynthesis of Flavonoids in Arabidopsis. In this work, we show that the rol1 mutants contain a modified flavonol glycosylation profile. A detailed analysis of the rol1-2 allele revealed aberrations in cell shape, which result in oversized cotyledon pavement cells that lack typical lobes and have ...

  • The Modified Flavonol Glycosylation Profile ... - Plant Cell

    Jun 01, 2008 · Flavonoids are secondary metabolites known to modulate plant growth and development. A primary function of flavonols, a subgroup of flavonoids, is thought to be the modification of auxin fluxes in the plant. Flavonols in the cell are glycosylated, and the repressor of lrx1 ( rol1 ) mutants of Arabidopsis thaliana , affected in rhamnose biosynthesis, have a modified flavonol glycosylation profile.
