MetabolomicsMetabolomics reveals an involvement of pantothenate for male production responding to the short-day stimulus in the water flea, Daphnia pulex
Under favorable conditions, the micro-crustacean Daphnia pulex produces female offspring by parthenogenesis, whereas in response to various unfavorable external cues, they produce male offspring to induce sexual reproduction (environmental sex determination: ESD). We recently established a suitable ...

TranscriptomicsIdentify differentially expressed genes in 14-day-old pkl seedlings
CHD3 proteins are ATP-dependent chromatin remodeling factors that are components of diverse multisubunit complexes that can either repress or activate gene expression. In plants, the CHD3 protein PICKLE (PKL) is necessary for repression of seed-specific genes during germination and promotes depositi...

TranscriptomicsGlycine max Transcriptome or Gene expression
Soybean (Glycine max, cv Williams82) leaf petiole explants exposed to 25 ul/l ethylene for 0 to 72 h. Explants were prepared from 21 day-old greenhouse grown plants. Leaf abscission zones (LAZ) consisted of 2 mm of tissue collected below the leaf blade. The petioles (NAZ) consisted of approximately ...

GenomicsGlutamine methylation on Histone H2A is an RNA Polymerase I dedicated modification
Nucleosomes are decorated with numerous post-translational modifications capable of influencing many DNA processes. Here, we describe a new class of modification, methylation of glutamine, occurring on yeast histone H2A at position 105 (Q105) and human H2A at Q104. We identify Nop1 as the methyltran...

GenomicsVitamin C induces Tet-dependent DNA demethylation in ES cells to promote a blastocyst-like methylome [MeDIP-Seq]
DNA methylation is a heritable epigenetic modification involved in gene silencing, imprinting, and the suppression of retrotransposons. Global DNA demethylation occurs in the early embryo and the germline and may be mediated by Tet (ten-eleven-translocation) enzymes, which convert 5-methylcytosine (...

Transcriptomics17b-Trenbolone study
We investigated the genomic transcriptional response of female fathead minnows (Pimephales promelas) to an acute (4 day) exposure to 0.1 or 1.0 µg/L of, 17β-trenbolone (TB), the active metabolite of an anabolic androgenic steroid used as a growth promoter in cattle and a contaminant of concern in ...

ProteomicsA novel dual histone mark reader ZCWPW2 regulates meiotic recombination through lactylation and transcriptional control in humans and mice
Meiotic recombination ensures proper chromosome segregation and genetic diversity during gametogenesis, and its disruption leads to infertility. It is known that the dual histone methylation writer–reader system, in which PRDM9 deposits H3K4me3 and H3K36me3 marks at nucleosomes to specify recombinat...

MetabolomicsEvaluation of ambient mass spectrometry tools for assessing inherent postharvest pepper quality

Horticulturists are interested in evaluating how cultivar, environment, or production system inputs can affect postharvest quality. Ambient mass spectrometry approaches enable analysis of minimally processed samples under ambient conditions and offer an attractive high-throughput alternative for ...

TranscriptomicsNeurotoxicogenomic investigations to assess mechanisms of action of the munitions constituents RDX and 2,6-DNT in Northern bobwhite (Colinus virginianus) (part 5 of 10)
Munitions constituents (MCs) including hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), 2,4,6-trinitrotoluene (TNT), and TNT derivatives are recognized to elicit aberrant neuromuscular responses in many species. The onset of seizures resulting in death was observed in the avian model Northern bobwhite...
