Abstract
Cold stress is a major factor limiting production and geographic distribution of rice (Oryza sativa). Although the growth range ofjaponicasubspecies has expanded northward compared to modern wild rice (O. rufipogon), the molecular basis of the adaptation remains unclear. Here we reportbZIP73, a bZIP transcription factor-coding gene with only one functional polymorphism (+511？G>A) between the two subspeciesjaponicaandindica, may have facilitatedjaponicaadaptation to cold climates. We show thejaponicaversion of bZIP73 (bZIP73Jap) interacts with bZIP71 and modulates ABA levels and ROS homeostasis. Evolutionary and population genetic analyses suggestbZIP73has undergone balancing selection; thebZIP73Japallele has firstly selected from standing variations in wild rice and likely facilitated cold climate adaptation during initialjaponicadomestication, while theindicaallelebZIP73Indwas subsequently selected for reasons that remain unclear. Our findings reveal early selection ofbZIP73Japmay have facilitated climate adaptation of primitive rice germplasms.
