Fig. 3From: Transcriptome analysis of sweet potato responses to potassium deficiencyConfirmation the selected genes from transcriptomic profiles by real-time PCR. The sweet potato seedlings roots conducted with HK and LK for 14 d and used for qPCR verification. The experiments were repeated three times. The error bars represent ± SE. n = 3, HK: sufficient K; LK: Low-K+ treat; R: RootBack to article page
