Expression
1.14.11.9
Pohlia nutans
PnF3H expression levels increase by 2.49fold at 1 h and then slightly decrease to 1.47fold at 24 h with cold treatment. For the simulated drought stress (i.e. 20% PEG 6000), the PnF3H expression levels enhance by 2.39fold at 3 h and the transcript abundance remains high up to 12 h. In the UV-B radiation, the PnF3H expression levels increase and reach the maximum level of 4.57fold at 3 h. After exogenous abscisic acid treatment, the PnF3H expression levels increase quickly and reach the maximum level of 2.57fold at 0.5 h

physiological function
the enzyme plays a role in plant salt stress resistance. PnF3H transcripts are induced by various stress and may play a positive role in stress tolerance
