Molecular Interplay between Non-Host Resistance, Pathogens and Basal Immunity as a Background for Fatal Yellowing in Oil Palm ( Jacq.) Plants.

An oil palm ( Jacq.) bud rod disorder of unknown etiology, named Fatal Yellowing (FY) disease, is regarded as one of the top constraints with respect to the growth of the palm oil industry in Brazil. FY etiology has been a challenge embraced by several research groups in plant pathology throughout the last 50 years in Brazil, with no success in completing Koch's postulates.

Multi-omics Analysis of Young L. Plants' Responses to High NaCl Doses Reveals Insights into Pathways and Genes Responsive to Salinity Stress in this Halophyte Species.

Unlabelled: Soil salinity is among the abiotic stressors that threaten agriculture the most, and purslane ( L.) is a dicot species adapted to inland salt desert and saline habitats that hyper accumulates salt and has high phytoremediation potential. Many researchers consider purslane a suitable model species to study the mechanisms of plant tolerance to drought and salt stresses.

Insights from a Multi-Omics Integration (MOI) Study in Oil Palm ( Jacq.) Response to Abiotic Stresses: Part Two-Drought.

Drought and salinity are two of the most severe abiotic stresses affecting agriculture worldwide and bear some similarities regarding the responses of plants to them. The first is also known as osmotic stress and shows similarities mainly with the osmotic effect, the first phase of salinity stress. Multi-Omics Integration (MOI) offers a new opportunity for the non-trivial challenge of unraveling the mechanisms behind multigenic traits, such as drought and salinity resistance.

Insights from a Multi-Omics Integration (MOI) Study in Oil Palm ( Jacq.) Response to Abiotic Stresses: Part One-Salinity.

Oil palm ( 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.

Metabolic effect of drought stress on the leaves of young oil palm (Elaeis guineensis) plants using UHPLC-MS and multivariate analysis.

The expansion of the oil palm in marginal areas can face challenges, such as water deficit, leading to an impact on palm oil production. A better understanding of the biological consequences of abiotic stresses on this crop can result from joint metabolic profiling and multivariate analysis. Metabolic profiling of leaves was performed from control and stressed plants (7 and 14 days of stress).

Metabolite characterization of fifteen by-products of the coffee production chain: From farm to factory.

Approximately 11.4 million tonnes of solid by-products and an increased amount of waste water will be generated during the 2020/21 coffee harvest. There are currently no truly value-adding uses for these potentially environmentally threatening species.

Targeted Metabolomics of Xylose-Fermenting Yeasts Based on Mass Spectrometry.

Mass spectrometry is a sensitive and selective analytical technique that enables detection and quantitation of low abundance compounds in a complex sample matrix. Targeted metabolomics allows for quantitative analysis of metabolites, providing kinetic information of production and consumption rates, an essential step to investigate microbial metabolism. Here, we describe a targeted metabolomics protocol for yeast samples, from sample preparation to mass spectrometry analysis, which enables the identification of metabolic fluxes after xylose consumption.

New Protocol Based on UHPLC-MS/MS for Quantitation of Metabolites in Xylose-Fermenting Yeasts.

Xylose fermentation is a bottleneck in second-generation ethanol production. As such, a comprehensive understanding of xylose metabolism in naturally xylose-fermenting yeasts is essential for prospection and construction of recombinant yeast strains. The objective of the current study was to establish a reliable metabolomics protocol for quantification of key metabolites of xylose catabolism pathways in yeast, and to apply this protocol to Spathaspora arborariae.

Development and validation of an RP-HPLC method for quantification of cinnamic acid derivatives and kaurane-type diterpenes in Mikania laevigata and Mikania glomerata.

MIKANIA GLOMERATA and MIKANIA LAEVIGATA (Asteraceae) are medicinal plants popularly named 'guaco' in Brazil. The leaves of both species are used to treat respiratory diseases, with coumarin (CO) and kaurane-type diterpenes being regarded as the bioactive constituents. A new and simple RP-HPLC method was developed and validated for the simultaneous quantification of CO, O-coumaric (OC), benzoylgrandifloric (BA), cinnamoylgrandifloric (CA) and kaurenoic (KA) acids in the species.
