Fig. 5From: The genetic architecture of phosphorus efficiency in sorghum involves pleiotropic QTL for root morphology and grain yield under low phosphorus availability in the soilExpression profile of SbPSTOL1 genes found near QTLs for grain yield and root morphology (Fig. 3d) via quantitative RT-PCR. Whole root systems of the parents cultivated in nutrient solution with low-P for 13 days were collected, frozen, and used for quantitative RT-PCR. Expression was assessed using the 2-ΔΔCT method [69]. Different letters indicated statistical differences by the t-test (p-values ≤0.05). Error bars are shownBack to article page
