Project description:To investigate effects of intake of mulberry leaf extracts on hypercholesterolemia, we performed gene expression profiling on rat liver by microarray analysis. Microarray analysis revealed that mulberry leaf extracts up-regulated the gene expression involved in suppression of cholesterol synthesis and stimulation of innate-adaptive Immunity. Mice were fed a high-cholesterol diet without/with orally administration of mulberry leaf extracts for 4 weeks. Livers were taken for RNA extraction and hybridization on Agilent microarrays.
Project description:Bacterial wilt, caused by the soil-borne bacterium Ralstonia solanacearum, is a lethal disease of mulberry, but the molecular mechanisms of the host resistance responses to R. solanacearum remain unclear. In order to better understand molecular resistance mechanisms to R. solanacearum in mulberry, we set out to define the changes in gene expression of resistance and susceptible mulberry cultivars after inoculation with R. solanacearum. Susceptible cultivar YSD10, resistance cultivar KQ10 and YS283 were inoculation with R. solanacearum, mulberry root samples were collected at 1 dpi and non-treated control in all cultivars. Then we performed RNA-Seq analyses on all mulberry root samples using Illumina HiSeq 2000.
Project description:Mulberry (Morus atropurpurea) is an important economic woody tree with rapid growth rate and large biomass, which had great potential for heavy metals remediation. To further understand the mechanisms involved in cadmium accumulation and detoxification in mulberry, we carried out a transcriptomic study to get insights into the molecular mechanisms of the mulberry response to cadmium stress using RNA-seq analysis with BGISEQ-500.
Project description:Ciboria carunculoides is a major fungal pathogen that infect of mulberry fruit causing popcorn disease leading extensive damage and productivity loss. In spite of such a major impact, mulberry fruit response to C. carunculoides infection is yet to be witnessed. We carried out a transcriptomic study to get insights into the molecular mechanisms and dynamics of the mulberry fruit response to the C. carunculoides infection using RNA-seq analysis with Illumina HiSeq 2000.
Project description:Autotetraploid carries several phenotypic changes with larger leaves and fruit compared to diploid. To analysis of phenotypic changes in mulberry autotetraploids on the transcriptome, we performed RNA-Seq analyses on mulberry leaf samples of diploid and autotetraploids using Illumina HiSEq 2000.
Project description:Mulberry (Morus alba L.) is considered a millenary medicinal plant and a food source for silkworms. Different M. alba extracts offer a variety of biological and pharmacological properties that are largely attributed to stilbenoids, a small group of phenylpropanoids, including resveratrol and oxyresveratrol. These are naturally present in non-renewable parts of mulberry trees, impeding their efficient extraction. As a way to bypass this spatiotemporal restriction, we generated cell suspensions from mulberry leaf petioles and demonstrated that the combined use of methyl jasmonate and two different types of cyclodextrins were able to elicit a high production of resveratrol and oxyresveratrol. As oxyresveratrol-producing enzymes are still unknown, we improved the structural and functional annotation of the mulberry genome by integrating short and long-read sequencing data and combined it with time series transcriptome, metabolite and proteome data in response to cell elicitation to identify a complete set of phenylpropanoid and stilbenoid related genes. These included 23 stilbene synthase (STS) genes and a group of six p-coumaroyl-CoA 2'-hydroxylases (C2’Hs), all being highly co-expressed with resveratrol and oxyresveratrol production. We transiently transformed grapevine (Vitis vinifera L.) calli and Nicotiana benthamiana plants to functionally validate the role of C2’Hs in the first committed step of oxyresveratrol synthesis, which provides an alternative substrate for STSs by hydroxylating p-coumaroyl-coA into 2’4’-dihydroxycinnamoyl-CoA. Finally, we offer tools for genomic and transcriptomic exploration also in the context of jasmonate elicitation aiding in the characterization of novel stilbenoid-modifying and regulatory genes in the Morus genus.
Project description:To investigate effects of intake of mulberry leaves on hyperlipidemia, we performed gene expression profiling on rat liver by microarray analysis. Microarray analysis revealed that mulberry leaves up-regulated the genes involved in alpha-, beta-, and omega-oxidation of fatty acids, mainly relating to peroxisome proliferator-activated receptor signaling pathway, and down-regulated the gene expression involved in lipogenesis. Furthermore, the genes relating to response to oxidative stress were up-regulated in rats administrated mulberry leaves.
