The effects of TgSWO and the different FRDP on cell architecture in the various treatments. a The CLSM analysis results of the root tips from the CK and 75 μM TgSWO treatments, and the white dotted squares represent the change of cell arrangement. b The CLSM analysis results of the root tips from the CK and 200 μM TgSWO treatments, and the white dotted squares represent the change in cell size. Graphics were representative of at least 15 independent roots for every treatment. c The slice analysis results of the root tips in different treatments after treatment with TgSWO and other FRDP for 48 h. SWO (15 µM), ΔCBD (7 µM), and ΔYoaJ (10 µM) were used to treat the cucumber seedlings; CK was without any protein; and the red arrow indicates the cell wall intracellular space
