Project description:BACKGROUND:Mulberry dwarf (MD), which is caused by phytoplasma, is one of the most serious infectious diseases of mulberry. Phytoplasmas have been associated with diseases in several hundred plant species. The inability to culture phytoplasmas in vitro has hindered their characterization at the molecular level. Though the complete genomes of two phytoplasmas have been published, little information has been obtained about the proteome of phytoplasma. Therefore, the proteomic information of phytoplasmas would be useful to elucidate the functional mechanisms of phytoplasma in many biological processes. RESULTS:MD phytoplasmas, which belong to the 16SrI-B subgroup based on the 16S DNA analysis, were purified from infected tissues using a combination of differential centrifugation and density gradient centrifugation. The expressed proteome of phytoplasma was surveyed by one-dimensional SDS-PAGE and nanocapillary liquid chromatography-tandem mass spectrometry. A total of 209 phytoplasma proteins were unambiguously assigned, including the proteins with the functions of amino acid biosynthesis, cell envelope, cellular processes, energy metabolism, nucleosides and nucleotide metabolism, replication, transcription, translation, transport and binding as well as the proteins with other functions. In addition to these known function proteins, 63 proteins were annotated as hypothetical or conserved hypothetical proteins. CONCLUSIONS:Taken together, a total of 209 phytoplasma proteins have been experimentally verified, representing the most extensive survey of any phytoplasma proteome to date. This study provided a valuable dataset of phytoplasma proteins, and a better understanding of the energy metabolism and virulence mechanisms of MD phytoplasma.

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:Background: Witches’ broom disease of Mexican lime (Citrus aurantifolia L.), which is caused by the phytoplasma “Candidatus Phytoplasma aurantifolia”, is a devastating disease that results in significant economic losses. Plants adapt to abiotic stresses by regulating gene expression at the transcriptional and post-transcriptional levels. MicroRNAs (miRNAs) are a recently identified family of molecules that regulate plant responses to environmental stresses through post-transcriptional gene silencing. Methods: Using a high-throughput approach to sequence small RNAs, we compared the expression profiles of miRNAs in healthy Mexican lime trees and in plants infected with “Ca. Phytoplasma aurantifolia”. Results: Our results demonstrated the involvement of different miRNAs in the response of Mexican lime trees to infection by “Ca. Phytoplasma aurantifolia”. We identified miRNA families that are expressed differentially upon infection with phytoplasmas. Most of the miRNAs had variants with small sequence variations (isomiRs), which are expressed differentially in response to pathogen infection. Conclusions: It is likely that the miRNAs that are expressed differentially in healthy and phytoplasma-infected Mexican lime trees are involved in coordinating the regulation of hormonal, nutritional, and stress signalling pathways, and the complex interactions between them. Future research to elucidate the roles of these miRNAs should improve our understanding of the level of diversity of specific plant responses to phytoplasmas.

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.
