Northern blot analysis of SnRK2.8 under nutrient-deprived conditions and during a 24-h light-dark cycle. (A) The expression of SnRK2.8 was down-regulated by nutrient deprivation. Shown are Arabidopsis Col-0 roots 6 h and 30 h after deprivation, grown in full nutrient conditions (+NPK) or without K+ (−K), N (−N), and P (−P). (B) Expression of SnRK2.8 in leaves from soil grown Col-0 plants. Each number indicates the time of harvest during one 24-h period. The lights went on at 500 and off at 2100. The rRNA bands in ethidium bromide-stained gels are shown as loading controls.
