Fig. 5: Proline enhances the biological efficacy of HAVs against Sclerotinia stem rot of oilseed rape and improves yield.

From: Plants interfere with non-self recognition of a phytopathogenic fungus via proline accumulation to facilitate mycovirus transmission

Fig. 5

A Symptoms of Sclerotinia stem rot on oilseed rape after spraying with hyphal fragment suspensions of Ep-1PN with and without proline. In the upper panel, grayish-yellow colors signify diseased plants; in the lower panel, grayish-yellow discoloration of stems is evident and caused by S. sclerotiorum. B Application of Ep-1PN with and without proline improved yield and suppressed stem rot in field experiments as compared to controls (proline and water). C The putative model for plant-derived proline-mediated inhibition of fungal non-self recognition reaction to promote mycovirus transmission. The interaction between plants and phytopathogenic fungi results in increasing proline accumulation, which promotes mycovirus transmission between incompatible fungi via inhibition of fungal non-self recognition system. Donor strain Ep-1PN is incompatible with recipient strain 1980. Source data are provided as a Source Data file.
