Project description:Asterids is one of the major plant clades comprising of many commercially important medicinal species. One of the major concerns in medicinal plant industry is adulteration/contamination resulting from misidentification of herbal plants. This study reports the construction and validation of a microarray capable of fingerprinting medicinally important species from the Asterids clade.
Project description:Plant growth-promoting rhizobacteria (PGPR) are soil microbes that can promote plant growth and/or increase plant resistance to one or multiple stress conditions. These natural resources are environmentally friendly tools for reducing the use of chemical fertilizers and pesticides and for improving the nutritional quality of plants, including pharmacological metabolites. Coriander (Coriandrum sativumL.), commonly known as cilantro or Chinese parsley, is a worldwide culinary and medicinal plant with both nutritional and medicinal properties. Little is known about how PGPR may promote plant growth or affect metabolite profiles in coriander. Here, by usingAeromonassp. H1 that is a PGPR strain, we investigate how coriander yield and quality could be affected by PGPR with transcriptome insights.
Project description:Panax japonicus C. A. Mey. is a rare and endangered Class II important protected wild medicinal plant in China with a wide range of pharmacological activities. The development of the fruit is special, only the apical capitulum can develop into fruit normally, and the colour trait changes during the maturation process showed a pattern from green to red and from red to purple-black.
Project description:Pinellia (Pinellia ternata (Thunb.) Breit.), as important medicinal plant, has been used to treat various ailments for a long time. The sixteen ploid plant (2n=16*13=208) Pinellia T2Plus line was obtained from an octoploid (2n=8*13=104) T2 line by chromosome-doubling technique. Compared with T2 line, the content of various medicinal components (polysaccharide, guanosine, adenosine and ephedrine) was increased in T2Plus line. In this study, the transcriptome of T2 line and T2Plus line were characterized by RNA sequencing (RNA-seq) technology. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enrichment analysis on differential expressed unigenes (DEGs) revealed that multiple metabolic pathway were enriched significantly, such as ‘Starch and sucrose metabolism’, ‘Purine metabolism’, ‘Photosynthesis’ and six transcription factors (MYB, WRKY, bHLH, LBD lateral organ boundaries domain (LBD), HD-ZIP homeodomain-zipper (HD-ZIP) and ERF Ethylene-responsive factor (ERF) ) play a key role in difference of transcriptome between T2 line and T2Plus line. These metabolic pathways and transcription factors may play an important role in the difference of medicinal components and epigenetic features between these two Pinellia cultivars. This conclusion provides a robust theoretical basis for the mechanism of the formation of medicinal ingredients in Pinellia cultivars.
Project description:In this study, we aim to present a global transcriptome analysis of medicinal plant, Catharanthus roseus. We generated about 343 million high-quality reads from three tissues (leaf, root and flower) using Illumina platform. We performed an optimized de novo assembly of the reads and estimated transcript abundance in different tissue samples. The transcriptome dynamics was studied by differential gene expression analyses among tissue samples.

Project description:Transcriptome analysis of medicinal plant Ajowan (Trachyspermum ammi L.)
Project description:In this study, we aim to present a global transcriptome analysis of medicinal/spice plant, Crocus sativus. We generated about 206 million high-quality reads from five tissues (corm, leaf, Tepal, stamen and stigma) using Illumina platform. We performed an optimized de novo assembly of the reads and estimated transcript abundance in different tissue samples. The transcriptome dynamics was studied by differential gene expression analyses among tissue samples.
Project description:We investigated the effects of the crude extract of a South African medicinal plant, Cotyledon orbiculata, on cell survival of colon (HCT116) cancer cell lines. Using RNASeq, we discovered that the extract interfered with mRNA regulatory pathways. Here, we found that the extract of Cotyledon orbiculata, a South African medicinal plant, had an anti-proliferative effect in cancer cells, mediated by apoptosis induced by alternative splicing of hnRNPA2B1 and BCL2L1.
