A multiOMICs approach shed light on the higher yield phenotype and abiotic stress tolerance in tobacco lines expressing the carrot lycopene β-cyclase1

Project description:Recently we published a set of tobacco lines, expressing the Dacucus carota (carrot) DcLCYB1 gene, with accelerated development, increased carotenoid content, and plant yield. Due to this, expression of DcLCYB1 might be of general interest in crop species as a strategy to accelerate plant development and increase biomass production under adverse field conditions. However, to follow this path, a better understanding of the molecular basis of this phenotype is essential. Here, we combine OMICs (RNAseq, proteomics, metabolomics, and lipidomics) and stress experiments to advance our understanding on the broader effect of the LCYB expression on the tobacco genome and metabolism.

A multi-OMICs approach sheds light on the higher yield phenotype and enhanced abiotic stress tolerance in tobacco lines expressing the carrot lycopene β-cyclase1 gene

Project description:Here, we combine OMICs (RNAseq, proteomics, and metabolomics) approaches to advance our understanding of the broader effect of LCYB expression on the tobacco genome and metabolism. DcLCYB1 gene with accelerated development, increased carotenoid content, photosynthetic efficiency, and yield might be of general interest in crop species as a strategy to accelerate development and increase biomass production under field conditions. Upon DcLCYB1 expression, the tobacco genome (~2000 genes), proteome (~700 proteins), and metabolome (26 metabolites) showed a high number of changes in the genes involved in metabolic processes related to cell wall, lipids,glycolysis, and secondary metabolism. Gene and protein networks revealed clusters of interacting genes and proteins mainly involved in ribosome and RNA metabolism and translation. In addition, abiotic stress-related genes and proteins were mainly upregulated in the transgenic lines. This was well in line with an enhanced stress (high light, salt, and H2O2) tolerance response in all the transgenic lines compared with the wild type. Altogether, our results show an extended and coordinated response beyond the chloroplast (nucleus and cytosol) at the genome, proteome, and metabolome levels, supporting enhanced plant growth under normal and stress conditions. This final evidence completes the set of benefits conferred by the expression of the DcLCYB1 gene, making it a very promising bioengineering tool to generate super crops.

A Multi-OMICs Approach Sheds Light on the Higher Yield Phenotype and Enhanced Abiotic Stress Tolerance in Tobacco Lines Expressing the Carrot <i>lycopene</i> β<i>-cyclase1</i> Gene.

Project description:Recently, we published a set of tobacco lines expressing the Daucus carota (carrot) DcLCYB1 gene with accelerated development, increased carotenoid content, photosynthetic efficiency, and yield. Because of this development, DcLCYB1 expression might be of general interest in crop species as a strategy to accelerate development and increase biomass production under field conditions. However, to follow this path, a better understanding of the molecular basis of this phenotype is essential. Here, we combine OMICs (RNAseq, proteomics, and metabolomics) approaches to advance our understanding of the broader effect of LCYB expression on the tobacco transcriptome and metabolism. Upon DcLCYB1 expression, the tobacco transcriptome (~2,000 genes), proteome (~700 proteins), and metabolome (26 metabolites) showed a high number of changes in the genes involved in metabolic processes related to cell wall, lipids, glycolysis, and secondary metabolism. Gene and protein networks revealed clusters of interacting genes and proteins mainly involved in ribosome and RNA metabolism and translation. In addition, abiotic stress-related genes and proteins were mainly upregulated in the transgenic lines. This was well in line with an enhanced stress (high light, salt, and H2O2) tolerance response in all the transgenic lines compared with the wild type.

Small RNA loci annotation in cacao, spinach and carrot

Project description:Cacao, spinach and carrot are three important crops with high valuable markets. For these species there isn't already an available genome-wide annotation of small rna. Here, for the first time, we sequenced and annotated small RNAs.

Global changes in gene expression in Caco-2 cell line by treatment with extract from iodine-biofortified carrot and lettuce

Project description:Whole genome microarray data were analyzed to describe the changes in gene transcription profile in human Caco-2 cancer cells under the influence of the extract from iodine-biofortified and non-fortified carrot and lettuce. These iodine-biofortified vegetables can be used as a functional food. Four-condition experiment: iodine-biofortified carrot, non-fortified carrot, iodine-biofortified lettuce, non-fortified lettuce vs. Caco-2 colorectal adenocarcinoma cell line. Three biological replicates and three technical replicates.

Transcriptome evaluation of gene expression changes during carotenoid accumulation in the storage root of carrot (Daucus carota)

Project description:In this study, a cross species hybridization (CSH) approach was used to evaluate whole transcriptome changes during carotenoid accumulation in the storage root of carrot (Daucus carota). Carotenoids are isoprenoid compounds providing red, yellow and orange color to plants. Previous gene expression analyses of carotenoid accumulation in non-model plant species have primarily used a candidate gene approach. Since global transcriptome analyses require extensive genome sequence, in the absence of these genomic resources an alternate approach uses platforms developed for model plant species. To assess transcriptome patterns associated with carotenoid pigmentation in carrot storage root, two carrot sibling inbred lines, B8788, true breeding for orange color and B8750, true breeding for white root color, were hybridized to the Medicago Affymetrix GeneChip microarray. Near isogenic recombinant inbred lines B8788 and B8750, derived from a cross between white rooted wild carrot (QAL) and orange-rooted B493 were used for comparative analyzes to minimize background genetic differences. B8788 is true breeding for orange color whereas B8750 is true breeding for white storage root color. Carrots were grown in three pots for each genotype under greenhouse conditions and carrots were selected arbitrarily from these pots for harvest. Roots were harvested at approximately 11 weeks post planting when carotenoid accumulation becomes apparent in the storage root. Storage root tissue from sixteen individual carrot roots was pooled into three one-gram tissue pools of four carrots for each genotype.
