Transient Agrobacterium‐mediated transformations of corollas of wild type (WT) and pODO1:GFP‐ODO1 line 10 (T2) with 35S:NLS‐mCherry were performed as described previously (Moerkercke et al., 2012 (link); Verweij et al., 2008 (link)). After 2 days, GFP (505–550 nm bandpass emission filter, 488 nm excitation) and mCherry (585–615 nm bandpass emission filter, 561 nm excitation) were imaged with a Zeiss LSM 510 inverted microscope (Zeiss, https://www.zeiss.com). Images were analyzed with imagej (https://fiji.sc).
