Fig. 5From: SAPK2 contributes to rice yield by modulating nitrogen metabolic processes under reproductive stage drought stressSAPK2 influenced the rate of NO3− influx rate and nitrate concentration. a-b Analysis of NO3− influx rate among WT, sapk2 mutant lines and OE lines under control conditions (a) and drought stress conditions (b). c-d Analysis of nitrate concentration among WT, sapk2 mutant lines and OE lines under control conditions (c) and drought stress conditions (d). Data are shown as means ± SD (n = 20) from three replicates. A student’s t-test was used to generate P values; “**” indicate significance at P < 0.01Back to article page
