From: The effect of UV-B on Arabidopsis leaves depends on light conditions after treatment
Influence of UV-B on anthocyanins in Arabidopsis leaves. After the specified time period leaves were cut into halves and control and treated halves from 4 different leaves were pooled. Each measurement was repeated at least 3 times. Error bars indicate the standard error. a Anthocyanin content was analyzed by measuring absorbance at 532 nm and normalized to fresh weight in examined leaves. b and c Time-course of the relative expression of genes involved in anthocyanin biosynthesis: (b) PAL1 and (c) CHS normalized for the expression of four housekeeping genes (PDF2, UBC9, UBQ10, SAND). A single dark-adapted overnight control sample from day 0 was used as a reference for calculating relative expression levels
