The effects of ultraviolet light on anthocyanin accumulation in the adventitious roots of Sedum wrightii..
Several studies have supported the idea that anthocyanin accumulation may be a possible protection mechanism in plants against DNA damage caused by ultraviolet light. The following study explores the accumulation of anthocyanins in the adventitious root tips of Sedum wrightii using various treatments of ultraviolet light. The root tips were grown under four separate sets of conditions: UVA, UVA + low UVB, UVA + high UVB, or the control. Afterwards, the anthocyanins were extracted using acidified ethanol and centrifugation. The absorption of the extract was taken using a Beckman spectrophotometer. The values were converted to nanomoles per miligram of fresh weight and then the groups were compared using data analysis software. The results supported the hypothesized differences that occurred between the groups. The anthocyanin concentrations were significantly higher in the UVB treatments than the other groups.
