RESUMO
Traditional Chinese medicine is a treasure of Chinese culture, absorbing the wisdom of the Chinese people. Continuous application of new technologies makes traditional Chinese medicine research advance with the times. After several years of development, high-throughput transcriptome study has become a mature research tool in biology. This paper reviewed the advances in medicine transcriptome study, and compared two sequencing platforms, Roche's GS FLX platform and Illumina's HiSeq 2000 platform. Moreover, this paper introduced medicine transcriptome analysis process, with Panax quinquefolius and Lonicera japonica for examples, showing the characteristics of traditional Chinese medicine transcriptome studies. High-throughput transcriptome studies facilitate traditional Chinese medicine research with overall understand of functional genes, give clear elucidation of metabolic pathways, lay molecular foundation for the traditional Chinese medicine research and offer modern interpretation for traditional Chinese medicine theory. However, the current study faces several difficulties, including weak molecular basis, high sequencing cost and staff shortages in data anaysis. In the future, with the development in sequencing technology, the combination of transcriptome and other genomics, such as proteome and metabolome, will lay a solid foundation for the new high-throughput screening and developing model for the traditional Chinese medicine industry.

Costaria costata, with great commercial and industrial value, typically grows in low intertidal and subtidal retgions in East Asia. The complete mitochondrial genome of C. costata is determined as circular-mapping and AT-rich (65%). The 37,461 bp mitochondrial genome consists of 25 tRNAs, 38 genes (including ORFs) and 3 ribosome genes. The gene arrangement and component are identical to those of Laminaria mitochondrial genomes, which show highly conservative evolution in mitochondrial genomes within the Laminariales. Moreover, the C. costata mitogenome makes full use of nucleotide and genetic information by large amounts of gene overlappings for better adapting the evolution of small genomes.
