Overexpression of a Novel Component Induces HAK5 and Enhances Growth in Arabidopsis

Figure 2

Role of At4g18280 in salt stress and K+-deficiency. (a) Gene expression of HAK5 (crisscross bars) and At4g18280 (white bars) under salt stress. Three-day-old Col-0 seedlings germinated on control media were transferred onto control media or media containing 100 mM NaCl and grown for 7 days prior to analysis. Values are log2 ratios relative to the control condition. Error bars indicate standard error for three biological replicates with three technical replicates. Each sample contained more than 15 seedlings. Statistically significant differences ( ) compared to each control sample are indicated as asterisks. (b) Primary root lengths of Col-0 (black bars) and FOX1 (dotted bars). Three-day-old seedlings germinated on control media were transferred onto control media or media lacking K+ (−K) and grown for 11 days prior to measurement. Error bars indicate standard error ( ). Statistically significant differences ( ) compared to Col-0 are indicated as an asterisk. (c) Image of Col-0 and FOX1 on −K. Three-day-old seedlings germinated on control media were transferred onto −K and grown for 11 days prior to imaging.
