Project description:BACKGROUND: Western flower thrips are considered the major insect pest of horticultural crops worldwide, causing economic and yield loss to Solanaceae crops. The eggplant (Solanum melongena L.) resistance against thrips remains largely unexplored. This work aims to identify thrips-resistant eggplants and dissect the molecular mechanisms underlying this resistance using the integrated metabolomic and transcriptomic analyses of thrips-resistant and -susceptible cultivars. RESULTS: We developed a micro-cage thrips bioassay to identify thrips-resistant eggplant cultivars, and highly resistant cultivars were identified from wild eggplant relatives. Metabolomic profiles of thrips-resistant and -susceptible eggplant were compared using the gas chromatography-mass spectrometry (GC-MS)-based approach, resulting in the identification of a higher amount of quinic acid in thrips-resistant eggplant compared to the thrips-susceptible plant. RNA-sequencing analysis identified differentially expressed genes (DEGs) by comparing genome-wide gene expression changes between thrips-resistant and -susceptible eggplants. Consistent with metabolomic analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of DEGs revealed that the starch and sucrose metabolic pathway in which quinic acid is a metabolic by-product was highly enriched. External application of quinic acid enhances the resistance of susceptible eggplant to thrips. CONCLUSION: Our results showed that quinic acid plays a key role in the resistance to thrips. These findings highlight a potential application of quinic acid as a biocontrol agent to manage thrips and expand our knowledge to breed thrips-resistant eggplant.

Project description:Ginseng is one of the well-known medicinal plants, exhibiting diverse medicinal effects. Its roots possess anticancer and anti-aging properties and are being used in the medical systems of East Asian countries. Ginseng is grown in low-light and low-temperature conditions and its growth is strongly inhibited at temperatures above 25 ℃. However, the molecular responses of ginseng to heat stress are currently poorly understood, especially at protein level. Therefore, here we utilized a shotgun proteomics approach to investigate the effect of heat stress on ginseng leaves. Total proteins were isolated from control (25 ℃) and ginseng plants exposed to 35 ℃ for 1 and 3 days and subjected to in-solution trypsin digestion. A total of 3,359 ginseng proteins were identified when searched in an in-house developed RNA-seq (PAC-BIO) database.
Project description:Cold stimulation not only activates the thermogenesis activity of brown adipose tissue (BAT) but also induces browning of white adipose tissue (WAT). To elucidate the mechanisms underlying cold-induced thermogenesis and adipose tissue remodeling, we used RNA sequencing (RNA-seq) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) to examine the transcriptomic and proteomic profiles, respectively, of adipose tissue from mice exposed to cold or thermoneutral temperature. The male C57BL/6J mice were divided into three groups (5 mice/group), two groups were kept at 6 ˚C for 6 h and 24 h, respectively, and the control group were kept at 22 ˚C for 24 h. Subsequently, the BAT and inguinal WAT of each mouse were dissected and subjected to RNA-seq and data-independent acquisition (DIA)-based LC-MS/MS.
