 The study presents a high throughput Illumina-Ina sec analysis of the T-plant, Chamelea sinensis, which has previously been difficult to culture in vitro and transform. The transcriptum was analyzed at an unprecedented depth, resulting in 127,094 unigenes with an average length of 355 BP and an N50 of 506 BP. This number is 10 fold higher than existing C sinensis sequences deposited in GenBank. Sequence similarity analysis identified 55,088 unigenes that could be annotated with gene descriptions, conserved protein domains, or gene ontology terms. Targeted searches using these annotations revealed the majority of genes associated with several primary and secondary metabolic pathways important to T-quality, such as flavonoid, pheonide, and caffeine biosynthesis pathways. The study validated 13 unigenes related to pheonide and flavonoid synthesis using RT-PCR and QRT-PCR. The transcriptum dataset can serve as an important public information platform for gene expression, genomics, and functional genomic studies in C sinensis.
