Boosting Drought Resilience in Rice: The Priming Effects of Zaxinone and Its Mimics.

ABSTRACT: Climate change increasingly threatens global agriculture, with drought emerging as a major constraint on crop productivity. Plants activate complex adaptive responses, involving genetic, physiological, and hormonal networks, to cope with water deficit. Among these, carotenoid-derived phytohormones, abscisic acid, and strigolactones regulate drought responses through modulation of stomatal conductance, antioxidant defenses, and hormonal crosstalk. Zaxinone, an apocarotenoid metabolite, and its synthetic analogs Mimic of Zaxinone 3 (MiZax3) and MiZax5 have recently emerged as plant growth regulators and SL biosynthesis inhibitors in Oryza sativa. This study investigates the effects of zaxinone and its mimics on rice drought encompassing morphometric, ecophysiological, biochemical, and molecu
