Putrescine-responsive post-transcriptional feedback regulation of Arabidopsis ADC2 mediated by 5'-UTR elements
Putrescine (Put) is a bioactive polyamine that contributes to plant growth, development, and stress responses, whereas excessive Put accumulation impairs growth. However, how plants maintain Put levels within an appropriate range remains poorly understood. In Arabidopsis thaliana, expression of the arginine decarboxylase 2 (ADC2) gene is a major determinant of Put abundance. Here, we show that…
