Molecular Link between Leaf Coloration and Gene Expression of Flavonoid and Carotenoid Biosynthesis in Camellia sinensis Cultivar 'Huangjinya'.

ABSTRACT: 'Huangjinya' is an excellent albino tea germplasm cultivated in China because of its bright color and high amino acid content. It is light sensitive, with yellow leaves under intense light while green leaves under weak light. As well, the flavonoid and carotenoid levels increased after moderate shading treatment. However, the mechanism underlying this interesting phenomenon remains unclear. In this study, the transcriptome of 'Huangjinya' plants exposed to sunlight and shade were analyzed by high-throughput sequencing followed by de novo assembly. Shading 'Huangjinya' made its leaf color turn green. De novo assembly showed that the transcriptome of 'Huangjinya' leaves comprises of 127,253 unigenes, with an average length of 914 nt. Among the 81,128 functionally annotated unig
