Fig. 3From: SAPK2 contributes to rice yield by modulating nitrogen metabolic processes under reproductive stage drought stressSAPK2 influenced Nitrate, phosphorus, potassium content in rice grains under reproductive-stage drought. a-c Comparison of nutrient content including total nitrogen (a), phosphorus (b), potassium (c) among WT, sapk2 mutant lines and OE lines in rice seeds under reproductive-stage drought. d-f The expression analysis of SAPK2 under N (d), P (e), and K (f) deprivation. Transcript accumulation was assessed by qRT-PCR. 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
