The effects of TgSWO from Trichoderma guizhouense NJAU4742 on the growth of cucumber seedlings. a The growth of cucumber seedlings under different conditions, and the coculture time with NJAU4742 strain was 5 days. CK (the PGM medium + NJAU4742); T1 (the PGM medium + 1% glass fiber + NJAU4742); T2 (the PGM medium + 1% cellulose + NJAU4742); T3 (PGM medium + cucumber seedlings); T4 (PGM medium + cucumber seedlings + 1% cellulose); T5 (PGM medium + cucumber seedlings + NJAU4742); T6 (PGM medium + cucumber seedlings + 1% cellulose + NJAU4742). b The Leaf Area and SPAD values of cucumber seedlings in different treatments. c The Root fresh weight and Shoot fresh weight values of cucumber seedlings in the different treatments. d The expression of TgSWO from NJAU4742 strain under different treatments. All data were normalized to the housekeeping gene Tef1, which was used as an internal control and amplified under the same conditions, and the CK treatment (1 day) with the lowest expression set to 1. Each bar represents the mean of three biological replicates with SE, and statistically significant difference as evaluated by one-way ANOVA: *P < 0.05; **P < 0.01, ***P < 0.001. e Growth conditions of NJAU4742 strain in different mediums with root and cellulose as sole carbon sources
