Fig. 4: Effects of StRAP2.3 transcription on VI activity in cold-stored potato tubers of transgenic lines.

From: StRAP2.3, an ERF‐VII transcription factor, directly activates StInvInh2 to enhance cold-induced sweetening resistance in potato

a1 NBT histochemical staining indicating reduced acid invertase activity in tubers of OE potato plants. b1 NBT histochemical staining showing increased acid invertase activity in tubers of Ri potato plants. a2 Overexpression of StRAP2.3 significantly decreased the activity of vacuolar invertase. b2 RNAi of StRAP2.3 significantly increased the activity of vacuolar invertase. The potato tubers were stored at 4 °C for 30 days. Each data point is the mean value of three readings. The vertical bars represent the standard deviations; **P < 0.01
