Effect of BPBT Gene Silencing on Morphology of Petunia Seedlings.

Five-day-old (A) and 10-d-old (B) control and BPBT RNAi-10 seedlings grown under normal light/dark (12 h/12 h) conditions on half-strength MS medium. Five-day-old knockout seedlings exhibited fused (E) or supernumerary (D) cotyledons more frequently than controls (C). Etiolated 10-d-old seedlings of BPBT RNAi-10 grown on half-strength MS medium show elongated hypocotyls ([F] and [G]) in comparison with the control. Values are the average of 13 measurements. Bars indicate sd.
