Abstract: To analyze the effect of βaminobutyrie acid (BABA) on anthocyanin of leaves of Arabidopsis, 30old plants were sprayed with BABA while the control were sprayed with water. After treated with BABA, the content of anthocyanin was significantly lower than that of control. Furthermore, the results from RTPCR showed that CHS, LDOX, UF3GT were down regulated compared with contro1, while PAL showed an opposite trend. At the same time, the activity of PPO, which played an important role in the degradation of anthocyanin, showed higher level than control. In addition, the antioxidant capacity, the death rate of cells and electrical conductivity of leaves were also decreased with BABA treatment. All results suggested that BABA might inhibit the accumulation of anthocyanin in leaves of Arabidopsis in vitro.

Key words: β-aminobutyric acid
