A Novel AtKEA Gene Family, Homolog of Bacterial K+/H+ Antiporters, Plays Potential Roles in K+ Homeostasis and Osmotic Adjustment in Arabidopsis

Figure 7

The expression of AtKEAs responds differently to low K+ treatment.

Fourteen-day -old Arabidopsis seedlings (Col-0) were cultured on the 1/2 MS medium or modified MS without K+ (0 mM K+) or supplemented with 1mM or 160mM KCl for 8h. Actin7 gene was used as an internal positive control. The transcript levels of AtKEAs in the untreated control seedlings were set as 1.0. Error bars represent SE (n=3).
