Response of turnip (Brassica rapa) to UV-B irradiation

The response of plants to stress such as UV-radiation or drought highly depends on the species, cultivar, plant organ, developmental stage, and furthermore, is influenced by ecophysiological interactions. In this study, turnip plants were exposed to UV-B and phenolic compounds, anthocyanins and the activity of phenylalanine ammonia-lyase were assessed. The results showed that anthocyanin compound was declined, however, some phenolic compounds, and campherol, Isolutein, and quercetin increased. It seems that UV stress can induce phenolics, but not through PAL activation
