Project description: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.

Project description:Transcriptome analysis was performed on the rhizome tissues of Atractylodes macrocephala under different treatments. The four treatments were: sterile water irrigation alone, FS root irrigation, FS and AM201 root irrigation, and FS combined with methyltobuzin (TM) root irrigation. And the differential genes between AM201 and FO groups were identified and compared, which helps to reveal the resistance mechanism of AM201 to Atractylodes macrocephala root rot disease
Project description:The nematode Caenorhabditis elegans was treated with extracts of the Traditional Chinese Medicine plants Cuscuta chinensis and Eucommia ulmoides from the L4 stage. In aged worms (on the 7th and 12th day of adulthood) different health parameters were determined. Besides the prolongation of lifespan, we found that C. chinensis improved the swimming behavior, pharyngeal pumping rate, stress resistance, mechanosensation and memory of aged C. elegans. Furthermore, the extract treatment reduced the autofluorescence, which is a known biomarker of ageing. Thus, we concluded that C. chinensis is an overall healthspan enhancer. In contrast, the E. ulmoides extract specifically enhanced the lifespan and stress resistance of aged C. elegans, but did not improve any other health aspect. To reveal the mechanism behind the healthspan enhancing effects of C. chinensis, the transcriptome of treated and untreated C. elegans on the 12th day of adulthood was analysed. For comparison purposes, E. ulmoides treated nematodes were included in the analysis.
Project description:Pistacia chinensis Bunge is known as dioecious, but we have found wild monoecious individuals. In order to screen the candidate genes which may influence the sex expression or floral phenotypic differences of P. chinensis, the inflorescence buds for different sex types associated with the sex differentiation were selected and tested for small RNA sequencing. Sex-specific differentially expressed small RNA were discovered, combined with real-time PCR data, the regulation patterns of various sex types were first revealed. Our study represents the first detailed analysis of small RNA sequencing, providing more clues for understanding the mechanism of sex determination on P. chinensis.
