Photoregulation of phenylalanine ammonia‐lyase (PAL) and chalcone synthase (CHS) in the accumulation of anthocyanin in alpine and prairie ecotypes of Stellaria longipes under varied R/FR
We studied mRNA accumulation and enzyme activity of phenylalanine ammonia‐lyase (PAL) and chalcone synthase (CHS) in alpine and prairie ecotypes of Stellaria longipes . The results show that light is required for the induction of PAL and CHS and accumulation of anthocyanins. Although both the ecotyp...
