MU fluorescence due to β-glucuronidase (GUS) activity in switchgrass seedlings days after a 3-day cocultivation with Agrobacterium harboring pCambia1305.1, pCambia1305.2 and a control. The number of days after cocultivation is shown on the x axis, and the 4-methylumbelliferone (MU) fluorescence per seedling is shown on the y axis. Standard errors are shown for each measurement.
