Project description:Potentilla indica and Melastoma dodecandrum lour are medicinal herbs used in traditional Chinese medicine. We sampled the plants from Nanyang Technological University's herb garden for transcriptomics analysis.
Project description:Scutellaria baicalensis Georgi, a perennial herb, is an important medicinal plant that possesses broad pharmacological actions and contains flavonoids with good bioactivities such as anti-inflammation, anti-bacteria and anti-tumor. However, little is known on the molecular processes responsible for the medical properties of this species, owing to the absence of genomic resources such as available sequences of key enzyme genes in biosynthetic pathways. In this study, the RNA sequencing data of S. baicalensis were first generated and used for transcriptome analysis.
Project description:The annual cleistogamous herb Cardamine kokaiensis is an endemic plant along the Kokai River in Japan. We examined the differences in gene expression patterns among cleistogamous (CL), intermediate (INT), and chasmogamous (CH) flower by cross-species microarray analysis using an Arabidopsis thaliana Affymetrix high-density oligonucleotide microarray (GeneChip ATH1). We then discuss the molecular basis of the evolution of cleistogamy. Our results help to clarify the molecular basis of the evolution of plant mating systems that depend on environmental conditions.

Project description:Dendrobium officinale is a traditional medicinal herb with a mount of bioactive components. Alkaloid is one of the major active ingredients of Dendrobium plants, and its immune regulatory effects have been well-studied. A total of 4857 DEGs, including 2943 up- and 1932 down-regulated genes, were identified between the control and MeJA-treated groups. Several shikimate and methylerythritol 4-phosphate pathway genes and a number of MeJA-induced P450 family genes, aminotransferase genes and methyltransferase genes were identified, providing several important candidates to further elucidate the alkaloid biosynthetic pathway of D. officinale. Furthermore, a large number of MeJA-induced transcript factor encoding genes were identified, suggesting a complex genetic network affecting the alkaloid metabolism in D. officinale.
