Transcriptomics coupled with Metabonomics for elucidating differences between the components in different varieties Atractylodes

ABSTRACT: Atractylodes macrocephala is a traditional Chinese medicine in China. It is widely used in clinic and the market demand is great. The quality difference between A. chinensis(Bunge) Koidz and A. japonica Koidz.ex Kitam is great, which seriously affects its clinical curative effect. Determination of Atractylosin by High-performance liquid chromatography. Transcriptomics coupled with Metabonomics for elucidating differences between the components in A. chinensis(Bunge) Koidz and A. japonica Koidz.ex Kitam. It was found that ACS, ACC, PAL and NOS were the key genes and metabolites related to the synthesis of atractylodes macrocephala. The decrease of salicylic acid content in A. chinensis(Bunge) Koidz may lead to the decrease of its ability to mediate the elicitor of endophytic fungi, resulting in the down-regulation of the expression of TGAL4 transcription factor and the up-regulation of DOGL3 transcription factor in A. chinensis(Bunge) Koidz cells, which may affect the accumulation of Atractylosin. The study above provides a theoretical basis for elucidating the biosynthesis pathway of atractylosin in A. chinensis(Bunge) Koidz.
