| Research Abstract |
Juice sacs of Satsuma mandarin, Valencia orange, and Lisbon lemon were cultured in vitro to investigate the possible factors which regulated xanthophyll accumulation in citrus fruit. Xanthophyll accumulation and the expression of genes related to xanthophyll biosynthesis and catabolism were regulated by the treatments of phytohormones, water stress, and light irradiation with LED in the juice sacs. Thus, the results indicated that these factors are important to regulate xanthophyll accumulation in citrus fruit.
