Mutants of Silene pratensis which are unable to O-glycosylate isovitexin in the petals often possess leaves with a typically curled shape. These leaves are mainly found on the elongated flower stem and not in the rosette. Increased light levels stimulate the occurrence of the aberrant leaf shape. In older plants a rosette-tied O-glycosylation may get lost which results in curled rosette leaves.
