Transposable Element‐Mediated Structural Variation Drives Flower Colour Diversification in Camellia

Plant Biotechnology Journal, EarlyView.
ABSTRACT The role of transposable elements (TEs) in genome evolution and phenotypic diversification in Camellia remains poorly understood. Here, we present an integrated analysis of genome resequencing data from 237 Camellia accessions and 11 de novo genome assemblies representing all major floral colour types.

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Symmetrical Imidazo[1,5‐a]pyridine Dimers as Novel Organic Light Emitters: Bidirectional Synthesis and Photoluminescence Characterization

European Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
Imidazo[1,5‐a]pyridine dimers are synthesized via a bidirectional strategy and characterized by single‐crystal X‐ray diffraction. The key substitution position for tuning optical properties is identified. Photophysical studies, supported by density functional theory calculations, show fluorescence in the 490–580 nm range, with the most planar system ...

Inhibitors of the Detoxifying Enzyme of the Phytoalexin Brassinin Based on Quinoline and Isoquinoline Scaffolds

Molecules, 2017
The detoxification of the phytoalexin brassinin to indole-3-carboxaldehyde and S-methyl dithiocarbamate is catalyzed by brassinin oxidase (BOLm), an inducible fungal enzyme produced by the plant pathogen Leptosphaeria maculans.
