Fig. 6 From:通用电气nome-wide identification and analysis of high-affinity nitrate transporter 2 (NRT2) family genes in rapeseed (Brassica napusL.) and their responses to various stresses Heat maps ofBnNRT2family genes expression profiles responding to macronutrient deficiency simulated in hydroponics. For this assay, rapeseed seedlings were cultivated in hydroponics cultures containing low N, low P or low K nutrient solution. Seedlings reared under full nutrient conditions were regarded as control samples, andP = 0.05 was used as the threshold to identify significant differences in expression between different conditions. Significant treatments are marked with asterisks. CK: full nutrient condition, LN: N deficiency, LP: P deficiency, LK: K deficiency, L: leaf, R: root Back to article page
