Isoxaben does not affect cell plate formation. Cell division in moss protonemata expressing mScarlet-CSLD6 (magenta in merge) and mEGFP-tubulin (green in merge), stained with aniline blue for callose (blue in merge). (A) Cell treated with 20 µM isoxaben. (B) Cell treated with 20 µM Isoxaben and 25 µM LatB. Images are single focal plane confocal images from a time-lapse acquisition. Scale bar, 5 µm. Time stamp, min:sec.
