ddRT-PCR for 5NG4 A), EXP’ B) and OsSHR1 C) using serial dilutions of total root RNA. Left, 1D diagram of ddRT-PCR for 5NG4, EXP’ and OsSHR1 in serial dilutions of total root RNA ranging from 1 ng to 1 fg and in a negative control (H₂O). Right, diagrams showing the correlations of the percentages of positive droplets or copies per microliter with the amount (pg) of RNA per reaction. Red bar, threshold for droplet detection
