It has been reported that several osmotin proteins with antifungal activity possess β‐1,3‐glucanase activity, although there is no conclusive evidence linking these two activities.[52] Additionally, chitinases are another type of PR protein produced by plant cells in response to pathogen infection, capable of hydrolyzing chitin in fungal cell walls.[21] Through the analysis of protein hydrolase activity, we discovered that the GbOSM1 primarily disrupts cells by breaking down the cell walls of fungi, including chitin and glucan (Figure 3h; Figure S12, Supporting Information). The gene discussed is TMEM37; the disease is infection.
