β-隐黄质（beta-cry）是柑橘类水果中富含的一种抗氧化剂，在某些疾病尤其是癌症的预防和治疗中起着重要作用。为提高柑橘果皮中β-cry的含量，研究了蓝光（470 nm）和红光（660 nm）LED对温州蜜柑果皮中类胡萝卜素积累和类胡萝卜素合成相关基因表达的影响。结果表明，红光能诱导β-cry的积累，而蓝光对β-cry的积累没有影响。红光下β-cry的积累归因于CitPSY、CitPDS、CitZDS、CitLCYb 1、CitLCYb 2、CitHYb和CitZEP表达的同时增加。本研究结果可为提高柑橘类水果的商品价值和营养价值提供新的策略。
beta-Cryptoxanthin (beta-cry), an antioxidant abundant in citrus fruits, plays an important role in the prevention and treatment of certain diseases, especially cancers. In the present study, to increase the content of beta-cry in citrus flayed, the effects of blue (470 nm) and red (660 nm) light-emitting diode (LED) lights on the accumulation of carotenoids and expression of genes related to carotenoid biosynthesis were investigated in the flavedo of Satsuma mandarin. The results showed that accumulation of beta-cry was induced by red light, while it was not affected by blue light. The accumulation of beta-cry under red light was attributed to simultaneous increases in the expression of CitPSY, CitPDS, CitZDS, CitLCYb1, CitLCYb2, CitHYb, and CitZEP. The results presented herein might provide new strategies to enhance the commercial and nutritional value of citrus fruits.
