Genome‐wide and gene‐specific DNA methylation across developmental stages in Pogonomyrmex californicus: A socially polymorphic ant

open access: yesInsect Molecular Biology, EarlyView.
Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

The genomes of two key bumblebee species with primitive eusocial organization [PDF]

open access: yes, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

Gas Chromatography‐Based Methods for Profiling Volatile Off‐Aroma Compounds in Grain Legumes: A Review

open access: yesLegume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

The chemical ecology of armyworms [PDF]

open access: yes, 2013
Moths of the genus Spodoptera are economically important pest insects. The necessity to develop novel control strategies which may be included in integrated pest management schemes has led to the study of chemical communication in several species within ...

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Integrative Metabolomic and Transcriptomic Profiling Reveals the Chemical and Molecular Basis for Aroma Divergence in Isatis Fruits

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Integrative metabolomic and transcriptomic analyses revealed the chemical and molecular basis of aroma divergence in fruits of three Isatis species. Distinct volatile profiles and 44 key aroma‐active compounds defined species‐specific sensory characteristics, while co‐expression analysis identified NAC transcription factors and lipid‐derived pathway ...

Olfaction in mosquitoes [PDF]

open access: yes, 2007
Female mosquitoes are vectors of diseases, affecting both livestock and humans. The host-seeking and identification behaviors of mosquitoes are mediated mainly by olfactory cues. The peripheral olfactory organs of mosquitoes which perceive olfactory cues

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider

open access: yesMolecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

open access: yesAndrology, Volume 14, Issue 4, Page 978-991, May 2026.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.
