Plant growth promoting (a–d) and heat stress mitigation effect (c, d) of phytohormones and other secondary metabolites producing fungal endophyte Paecilomyces formosus LWL1 on japonica rice (Oryza sativa L.) cv. Dongjin under no stress (NS) and prolonged heat stress (HS)
Circle shows the deleterious effect of heat stress on endophytes free rice plant (c). However, the P. formosus LWL1 inoculation significantly reduced the deleterious effect as shown in (d)
