(b) Responses of IbBBX24-OE, IbBBX24-RNAi and WT sweet potato plants grown hydroponically in half-strength Hoagland solution (normal) or half-strength Hoagland solution containing 86 mM NaCl or 30% PEG6000. (c) Responses of IbBBX24-OE, IbBBX24-RNAi and WT sweet potato plants grown in transplanting boxes under control conditions (normal) or subjected to 200 mM NaCl, drought or 200 μM methyl viologen (MV). Representative photographs were taken after stress treatment for 4 wk (salt), 8 wk (drought) or 2 wk (MV). A time-course analysis of the phenotypes of IbBBX24-OE, IbBBX24-RNAi and WT plants grown in transplanting boxes under abiotic stresses is shown in Supporting Information Fig. S1. Data are shown as means±SD (n = 3). **, Significant difference from WT at P < 0.01 based on Student’s t-test (Adopted from Zhang et al., 2021)
