| Gliricidia sepium (Jacq.) Walp., a legume, is a medium-sized multipurpose plant originaly from Central America. At an economic level, gliricidia can improve water infiltration, increase the soil?s water retention capacity, reduce erosion, and restore the soil?s quality. This species can adapt to very high levels of salt stress (?20 dS m-1). Soil salinity is an environmental limiting factor for plant biomass production worldwide, and one-quarter of the irrigated area in agriculture has a problem with salinity stress. |

| 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... |

| 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. The current study carried out a comprehensive, large-scale, single-omics analysis (SOA) and MOI studies on the leaves of young oil palm plants submitted to water deprivation. After performing SOA, 1955 DE enzymes from transcriptomics analysis, 131 DE enzymes from proteomics analysis,... |

| Oil palm (Elaeis guineensis Jacq.) is one of the World?s most important oilseed crops. Together, palm oil and palm kernel oil, respond to about 35% of the global vegetable oil consumption. In Brazil, there are extensive areas suitable for oil palm cultivation outside the Amazon rainforest. |

| Soil salinity is one abiotic stress that threatens agriculture in more than 100 countries. Gliricidia [Gliricidia sepium (Jacq.) Kunth] is a multipurpose tree known for its ability to adapt to a wide range of soils; however, its tolerance limits and responses to salt stress are not yet well understood. In this study, after characterizing the morphophysiological responses of young gliricidia plants to salinity stress, leaf metabolic and transcription profiles were generated and submitted to single and integrated analyses. RNA from leaf samples were subjected to RNA sequencing using an Illumina HiSeq platform and the paired-end strategy. Polar and lipidic fractions from leaf samples were extracted and analyzed on an ultra-high-performance liquid... |

| Os fungos filamentosos são responsáveis pela produção de vários metabólitos, principalmente em cocultivo, devido às interações microbianas simularem um ambiente complexo de competição ou simbiose, que por sua vez estimula a produção de novos compostos químicos com grande aplicação industrial. Essas interações são facilmente classificadas conforme os efeitos ou ainda as alterações na macromorfologia estrutural do crescimento micelial, mas podem ainda ser complementadas através de ferramentas analíticas robustas. Uma das técnicas que pode ser empregada para esses estudos é a imagem química por espectrometria de massas (do inglês, Imaging Mass Spectrometry, IMS), pois permite informações complementares através da localização química espacial. Desta forma,... |

| Fungi can produce many bioactive metabolites, which are enhanced when challenged in co-culture competition. For a better evaluation of these metabolites, Mass Spectrometry Imaging (MSI) can be used to provide complementary information about the metabolite spatial localization. However, some adaptations are required on available methodologies in MSI for applications in microorganisms, particularly on sample preparation, due to the characteristics of each type of cell that has to be analyzed. The imprinting method has been shown to be a robust method when applied to sample preparation, but to our knowledge it has never been tested for microbial MALDI-MSI. Herein we applied both Classic and Imprinting MALDIMSI to compare and analyze metabolites produced by... |

| Abstract: 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). Samples were extracted and analyzed on a UHPLC-ESI-Q-TOF-HRMS system. Acquired data were processed using XCMS Online and MetaboAnalyst for multivariate and pathway activity analysis. Metabolism was affected by drought stress through clear segregation between control and stressed groups. More importantly, metabolism changed through time, gradually from 7 to... |

| A grande demanda de fonte energética despertou o uso de biodiesel derivados de óleos vegetais, tendo destaque para a cultura do algodão. A torta/farelo do caroço de algodão (TCA), oriundo da etapa de extração do óleo, é rica em proteína, lipídeos e carboidratos. No entanto, a TCA possui compostos, como o gossipol e a lignina, os quais necessitam de tratamento adequado para degradá‑los. A degradação destes compostos utilizando macrofungos tem se destacado, viabilizando assim a sua utilização na nutrição de animais. Portanto, é necessário prospectar os compostos químicos degradados e/ou produzidos após a fermentação com macrofungos. Esse trabalho teve como objetivo a caracterização de metabólitos presentes em TCA após a fermentação estado sólido de... |

| Soil salinity is among the abiotic stressors that threaten agriculture the most, and purslane (Portulaca oleracea 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. Here, a robust salinity stress protocol was developed and used to characterize the morphophysiological responses of young purslane plants to salinity stress; then, leaf tissue underwent characterization by distinct omics platforms to gain further insights into its response to very high salinity stress. |
