MetabolomicsUltra-High Mass Resolving Power, Mass Accuracy, and Dynamic Range MALDI Mass Spectrometry Imaging by 21-T FT-ICR MS

Detailed characterization of complex biological surfaces by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) requires instrumentation that is capable of high mass resolving power, mass accuracy and dynamic range. Fourier transform ion cyclotron resonance mass sp...

TranscriptomicsTranscriptional response of susceptible and tolerant citrus to infection with Candidatus Liberibacter asiaticus
Candidatus Liberibacter asiaticus (Las), a non-culturable phloem-limited bacterium, is the suspected causal agent of Huanglongbing (HLB) in Florida. HLB is one of the most devastating diseases of citrus and no resistant cultivars have been identified to date, though tolerance has been suggested in ...

TranscriptomicsCharacterization of the transcriptomes of genetically diverse Listeria monocytogenes exposed to hyperosmotic and low temperature conditions
A screening process was used to determine hyperosmotic as well as cold stress tolerance of a diverse set of Listeria monocytogenes strains and was based on the capacity to grow at sub lethal levels of NaCl and 4M-BM-0C. Analysis of gene expression in cells adapted to cold and hyperosmotic stress rev...

TranscriptomicsGene expression in Citrus sinensis (L.) Osbeck following infection with the bacterial pathogen Candidatus Liberibacter asiaticus causing Huanglongbing in Florida
Huanglongbing (HLB) (=citrus greening) is a destructive disease of citrus which is caused by a fastidious, phloem-inhabiting bacterium of the genus Candidatus Liberibacter. Large-scale analysis of gene expression changes in ‘Valencia’ orange leaves were studied during the course of 19 weeks after i...

TranscriptomicsTranscriptomic and phenotypic responses of L. monocytogenes with different growth efficiencies under acidic conditions
A screening process was used to determine the aciduric capacities of a diverse set of Listeria monocytogenes strains and was based on the capacity to grow at pH 5.0 in the presence 4 different organic acids. Food and clinical isolates tended to be more resistant but strain genetic groupings were fou...

GenomicsGenome-wide location analysis of BMP (SMAD1) in mouse erythroid progenitors co-occupted with lineage specific regulators (GATA1, GATA2)
Lineage regulators direct BMP and Wnt pathways to cell-specific programs during differentiation and regeneration Mouse G1E or G1ER cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell...

GenomicsGenome-wide location analysis of WNT (Tcf7l2) and BMP (SMAD1) in human hematopoeitic progenitors co-occupied with lineage specific regulators (GATA1, GATA2)
Lineage regulators direct BMP and Wnt pathways to cell-specific programs during differentiation and regeneration. This represents the human CD34 ChIP-seq portion of this dataset. Human hematopoietic cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitati...

ProteomicsIdentification of proteins using iTRAQ and VIGS revealed that three proteins were involved into cold response in bread wheat
iTRAQ-based quantitative proteomic and liquid chromatography tandem mass spectrometry (LC-MS/MS) methods were applied to identify protein spots involved in cold responses in wheat. By comparing the differentially accumulated proteins from the derivatives (UC1110 x PI 610750), as well as the F10 reco...

TranscriptomicsPhysiology and genetic activity of Listeria monocytogenes during multi-hurdle stress induced cell death
The physiological basis of the hypothesis that temperature is the primary governing factor of bacterial cell inactivation under otherwise non-growth permissive conditions was investigated. Application of simultaneous low pH (pH 3.5) and low water activity (aw = 0.9; 2.5 M NaCl) conditions, applied t...
