A V232M missense mutation in rice OsLSZ1, a lycopene β-cyclase, inhibits β-carotene biosynthesis and impairs chloroplast development during seedling stage at low temperatures.

Carotenoids are essential for chloroplast development, with lycopene β-cyclase as the rate-limiting enzyme in the biosynthesis of β-carotene and α-carotene. This study investigates the carotenoid biosynthetic alterations in a low-temperature-sensitiv…
