图5. 不同磷水平下供体玉米碳磷代谢基因表达情况(平均值±标准偏差)。LP和HP分别代表低磷和高磷处理。AMD和NMD代表供体植物接种AM真菌和不接种对照处理。柱形上方标示不同字母代表相应处理之间在5%水平有显著性差异。“#”表示相同接种处理不同磷水平之间在5%水平差异显著。Pht1;2, Pht1;6, 磷转运蛋白基因; PEPC, 磷酸烯醇式丙酮酸羧化酶基因; G3PT, 甘油-3-磷酸转运蛋白基因; TC289, 无机焦磷酸化酶基因; MAS1, 苹果酸合酶基因。

Fig. 5. Expression of genes relevant to C and P metabolism in maize roots from donor compartment under different P levels (mean ± SD). LP and HP refer to low P level (10 mg?kg-1) and high P level (100 mg?kg-1) respectively. AMD and NMD represent donor plants with and without AM fungus. Different letters above the columns indicate significant difference (p < 0.05) between corresponding treatments. # indicates significant difference (p < 0.05) between different P levels. Pht1;2, Pht1;6, P transporter genes; PEPC, phosphoenolpiruvate carboxylase gene; TC289, inorganic pyrophosphatase gene; G3PT, glycerol- 3-phosphate transporter gene; MAS1, malate synthase gene.
