The role of plant-derived smoke and karrikinolide in abiotic stress mitigation: An Omic approach

Abstract

Plant-derived smoke has the potential to be used in tissue culture, agriculture, and ecological restoration. Karrikin is an active constituent of plant-derived smoke and a strong germination stimulant. Karrikin and strigolactone share comparable signaling pathways and exhibit structural similarities. Smoke and its active ingredients promote seed germination as well as other physiological activities, such as seedling growth and abiotic stress mitigation. Additionally, plant-derived smoke and karrikin maintain oxidative equilibrium by controlling the cell's antioxidant machinery. In order to reduce abiotic challenges such oxidative damage, drought, and heavy metal stress, plant derived smoke as well as karrikin interacts with a number of phytohormones. Various genomics studies have been progressed in revealing the mechanism of action of plant derived smoke and karrikin in mitigation of abiotic stresses in plants. This review article focuses on the role of plant-derived smoke and karrikinolide in improving stress tolerance.
