Drought stress is a major abiotic stress which severely reduces the plant growth and limits agricultural productivity. Previous studies have demonstrated that lutein directly synthesized by the carotenoid epsilon-ring hydroxylase gene (LUT1) played crucial roles in regulating drought response. Notwithstanding the myriad studies on LUT1's response to drought stress in certain plant species such as Arabidopsis, the precise function mechanisms within tree species remain ambiguously understood. Our study reveals that under drought stress, TgLUT1, a novel LUT gene instrumental in β-lutein biosynthesis, was markedly up-regulated in Torreya grandis...
