Phytomelatonin prevents bacterial invasion
Webb20 jan. 2024 · As in a chemical arms race, Pst can produce coronatine, a phytotoxin that reverts the melatonin-induced stomatal closure, reopening these pores by 4 h after bacterial inoculation. Indeed, co-treatment of melatonin and coronatine inhibits the melatonin-induced stomatal closure in P. notoginseng leaves. Webb16 nov. 2024 · Melatonin has shown high efficacy in protecting plants against viral, fungal and bacterial pathogens along with insects and plant-parasitic nematodes (Moustafa-farag et al. 2024; Vielma et al. 2014 ).
