Project description:Oil palm (Elaeis guineensis Jacq.) is one of the most important oil-producing crops in the world. However, the demand for oil from this crop will increase in the future. A comparative gene expression profile of the oil palm leaves was needed in order to understand the key factors that influence the oil production. Here, we reported an RNA-seq dataset from three different oil yields and three different genetic populations of oil palm. All raw sequencing reads were obtained from an Illumina NextSeq 500 platform. We also provide a list of the genes and their expression levels resulting from the RNA-sequencing. This transcriptomic dataset will provide a valuable resource for increasing oil yield.

Project description:Oil palm (Elaeis guineensis) is a highly productive oil crop and the most consumed vegetable oil globally due to its unique oil characteristics. Palm oil production is affected by abiotic stresses, leading to food security issues and huge economic losses. To understand the oil palm responses to different abiotic stresses at the transcriptional level, we performed RNA-Seq analyses of oil palm leaves treated with drought, high salinity, heat, cold and flood stresses compared with controls. A total of 18 libraries (three biological replicates per treatment) were generated with approximately 843 million of total clean reads after data filtering. Clean reads were mapped to the oil palm reference genome at a total mapping rate of more than 70%. The quantification of expression analysis enabled the identification of potential abiotic stress-responsive genes, co-expressed under multiple abiotic stresses and unigenes that were induced by a specific abiotic stress. The availability of these RNA-Seq datasets will provide a better understanding of the abiotic stress response mechanisms to develop climate-resilient oil palm planting materials.

Project description:Oil palm breeding and seed development have been hindered due to the male parent's incapacity to produce male inflorescence as a source of pollen under normal conditions. On the other hand, a young oil palm plantation has a low pollination rate due to a lack of male flowers. These are the common problem of sex ratio in the oil palm industry. Nevertheless, the regulation of sex ratio in oil palm plants is a complex mechanism and remains an open question until now. Researchers have previously used complete defoliation to induce male inflorescences, but the biological and molecular mechanisms underlying this morphological change have yet to be discovered. Here, we present an RNA-seq dataset from three early stages of an oil palm inflorescence under normal conditions and complete defoliation stress. This transcriptomic dataset is a valuable resource to improve our understanding of sex determination mechanisms in oil palm inflorescence.

Project description:C57Bl/6J mice were put on a low fat diet (10 kcal% palm oil) or high fat diet (60 kcal% palm oil), combined with a low dietary Mg2+ (0.03 w/w% or 0.21 w/w%) for a period of 17 weeks. White adipose tissue was harvested and total RNA isolated using TRIzol, of which 5 samples per group were sent to BGI-China for RNA-Sequencing.

Project description:Oil palm (Elaeis guineensis Jacq.) is the number one source of consumed vegetable oil nowadays. It is cultivated in areas of tropical rainforest, where it meets its natural condition of high rainfall throughout the year. The palm oil industry faces criticism due to a series of practices that was considered not environmentally sustainable, and it finds itself under pressure to adopt new and innovative procedures to reverse this negative public perception. Cultivating this oilseed crop outside the rainforest zone is only possible using artificial irrigation. Close to 30% of the world’s irrigated agricultural lands also face problems due to salinity stress. Consequently, the research community must consider drought and salinity together when studying to empower breeding programs in order to develop superior genotypes adapted to those potential new areas for oil palm cultivation. Multi-Omics Integration (MOI) offers a new window of opportunity for the non-trivial challenge of unraveling the mechanisms behind multigenic traits, such as drought and salinity tolerance. The current study carried out a comprehensive, large-scale, single-omics analysis (SOA), and MOI study on the leaves of young oil palm plants submitted to very high salinity stress. Taken together, a total of 1239 proteins were positively regulated, and 1660 were negatively regulated in transcriptomics and proteomics analyses. Meanwhile, the metabolomics analysis revealed 37 metabolites that were upreg- ulated and 92 that were downregulated. After performing SOA, 436 differentially expressed (DE) full-length transcripts, 74 DE proteins, and 19 DE metabolites underwent MOI analysis, revealing sev- eral pathways affected by this stress, with at least one DE molecule in all three omics platforms used. The Cysteine and methionine metabolism (map00270) and Glycolysis/Gluconeogenesis (map00010) pathways were the most affected ones, each one with 20 DE molecules.

Project description:The beneficial effects of dietary long-chain (LC) n-3 polyunsaturated fatty acids (PUFA) in the prevention and/or treatment of some metabolic disorders result largely from their capacity to regulate the transcription level of many genes involved in metabolic and physiological homeostasis, especially in the liver. In this respect, they are known to bind and activate the Peroxisome Proliferator-Activated Receptor alpha (PPARalpha). The precursor of LC-PUFA, a-linoleic acid (ALA, C18:3 n-3) share some beneficial metabolic effects with its LC derivatives, however its role in gene regulation is poorly documented. Here, we analysed the hepatic transcriptome of mice fed for 5 weeks diets rich in either saturated FA from palm oil (PALM group) or ALA from linseed oil (LIN group). This modification of dietary fatty acid composition in a context of a high fat diet had a subtle but significant effect on the hepatic transcriptome. We identified mainly a group of genes that were upregulated in the LIN vs the PALM group and that include several well-known PPARalpha target genes involved in lipid and xenobiotic metabolism. Liver gene expression was measured in male C57BL/6J mice fed during 5 weeks a high fat diet (51% energy from fat) containing palm oil, rich in saturated fatty acids (n=10) or linseed oil, rich in 18:3 n-3 (n=8)

Project description:Palmitic acid (C16:0) is the most abundant saturated fatty acid in animals serving as a substrate in lipid synthesis and β-oxidation, and in the modification of proteins called palmitoylation. The influence of dietary palmitic acid on protein palmitoylation in the context of metabolic processes remains largely unknown. In this study we performed high-throughput proteomic analyses of the liver membrane fraction in the mouse to examine the influence of a palm oil-rich diet on the level and S-palmitoylation of proteins. For this purpose, mice were fed for 4 or 12 weeks a diet containing 19.1% of palm oil in addition to 4% soybean oil (45% kcal from fat) while 4% soybean oil (10% kcal from fat) was the only fat source in the control diet. Liver functioning and pro-inflammatory responses of the liver and peritoneal macrophages as well as the input of protein S-palmitoylation to these aspects were assessed in parallel. We found that the diet rich in palm oil induced transient accumulation of C16:0 and C18:1 fatty acids in murine liver leading to changes of the level and S-palmitoylation of numerous proteins involved in liver metabolism and selected innate immune responses. The relatively mild negative impact of such diet on liver functioning can be attributed to a lower bioavailability of palm oil-derived C16:0 vs. that of C18:1 and the efficiency of mechanisms preventing liver injury, including dynamic protein S-palmitoylation.
