“…Millsp.) seedlings with red light showed a protective effect against fungal pathogens in the early plant developmental stage: 12‐ and 24‐hours‐long red light exposure reduced disease wilt of Fusarium udum (Bansod, Sakhare, Deshmukh, & Moharil, 2017). This finding suggests that red light treatment could be effective against fungal pathogens during early plant development.…”

Light is essential for plant life. It provides a source of energy through photosynthesis and regulates plant growth and development and other cellular processes, such as by controlling the endogenous circadian clock. Light intensity, quality, duration and timing are all important determinants of plant responses, especially to biotic stress. Red light can positively influence plant defence mechanisms against different pathogens, but the molecular mechanism behind this phenomenon is not fully understood. Therefore, we reviewed the impact of red light on plant biotic stress responses against viruses, bacteria, fungi and nematodes, with a focus on the physiological effects of red light treatment and hormonal crosstalk under biotic stress in plants. We found evidence suggesting that exposing plants to red light increases levels of salicylic acid (SA) and induces SA signalling mediating the production of reactive oxygen species, with substantial differences between species and plant organs. Such changes in SA levels could be vital for plants to survive infections. Therefore, the application of red light provides a multidimensional aspect to developing innovative and environmentally friendly approaches to plant and crop disease management.

“…It was reported that red light, especially at night, can promote plant defense mechanisms against various phytopathogens (Gallé et al, 2021). Pretreatment with red light for 12 and 24 h reduced the wilt disease caused by F. udum in pigeon pea (Cajanus cajan) seedlings (Bansod et al, 2017). In the case of another fungus, the application of red light reduced the development of lesions by Botrytis cinerea and enhanced the accumulation of the antimicrobial compounds, as well as upregulating antioxidant defense-related and GST genes in grapevine (Vitis vinifera) leaves (Ahn et al, 2015).…”

Plant defense responses against Fusarium infection can be controlled by light. In this study, the effects of nocturnal red light were investigated on glutathione transferases (GSTs) in the leaves of the moderate- and high-Fusarium resistant wheat cultivars, GK Ígéret and GK Arató, respectively. GST activity increased in the light phase during the day, while it decreased after midnight. Since GST activity was lowest at midnight, we examined whether red light application at midnight could prevent the night-time drop in enzyme activity. We found that 15-min-long nocturnal red light application was effective to increase GST activity at dawn. The effects of red light pretreatments on GST expression and activity, as well as the oxidative stress induced by fumonisin B1 (FB1), were investigated. FB1 exposure increased GST activity and the expression of GST genes at dawn but nocturnal red light application in combination with the mycotoxin also increased GST activity and the transcript levels of the selected GSTs in the resistant GK Arató. In addition to its effects on GSTs, it was discovered that, depending on the degree of tolerance, nocturnal red light increased the activity of the major antioxidant enzymes at dawn in both of the chosen wheat genotypes. These decreased FB1’s oxidative stress-causing actions, resulting in lower lipid peroxidation and less cell viability loss when exposed to the mycotoxin. Pretreatment with nocturnal red light enhanced the activity of GST and antioxidant enzymes in wheat plant leaves, contributing to FB1 detoxification and reducing oxidative stress.
