Pathogen-induced callose deposition in TRV:00 and TRV:GhGLP2 cotton plants. (a, c) Representative photographs and 3D surface plots of callose staining in TRV:00 and TRV:GhGLP2 cotton plants after inoculation with Verticillium dahliae or Fusarium oxysporum at 24, 48 and 72 h post-inoculation (hpi). (b, d) Quantification of total callose in V. dahliae or F. oxysporum inoculated cotton plants. Data represent the means ± SD of three independent biological replicates (n ≥ 10). Student’s t-test, *P < 0.05, **P < 0.01 compared to wild-type or control plants. Bar = 500 μm.
