Comparative transcriptome profiling reveals distinct regulatory responses of secondary defensive metabolism in Datura species (Solanaceae) under plant development and herbivory‐mediated stress

Ecology and Evolution
Differential expression of genes is key to mediating developmental and stress‐related plant responses. Here, we addressed the regulation of plant metabolic responses to biotic stress and the developmental variation of defense‐related genes in four ...

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.

Physiology and Transcriptomics Reveal Divergent Strategies of Mycorrhiza‐Mediated Drought Adaptation in Poplar

Plant, Cell &Environment, EarlyView.
ABSTRACT Mycorrhizal symbiosis shapes plant growth and stress resilience. Here, we compared physiological and molecular responses of poplars (P. x canescens) colonised by Paxillus involutus (Pi) or Cenococcum geophilum (Cg) under control conditions, drought stress and recovery.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

Plant Biology, EarlyView.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.

Regulation of Glandular Size and Phytoalexin Biosynthesis by a Negative Feedback Loop in Cotton

Advanced Science
Plants have evolved diverse defense mechanisms encompassing physical and chemical barriers. Cotton pigment glands are known for containing various defense metabolites, but the precise regulation of gland size to modulate defense compound levels remains ...

Size of chloroplasts in Arabidopsis mesophyll cells affects jasmonate biosynthesis

Plant Biology, EarlyView.
The relationship between chloroplast structure and hormone biosynthesis capacity is poorly understood. This study shows that mutants harbouring giant chloroplasts produce more jasmonic acid upon mechanical stress than wild‐type plants, suggesting that organellar architecture is a previously unrecognized factor associated with plant hormone biosynthesis

Putative involvement of lncRNA, miRNA, and mRNA‐mediated ceRNA network regulation in drought priming to enhance drought tolerance in Nicotiana tabacum

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Drought priming increased the tolerance of Nicotiana tabacum to severe, recurring drought stress by modulating the expression of stress‐related genes via long non‐coding RNAs (lncRNAs), which acted as competing endogenous RNAs (ceRNAs) for microRNAs (miRNAs) and messenger RNAs (mRNAs).

Evaluating putative lncRNA‐mediated ceRNA regulatory network involving miR396 and miR319 in maize leaf growth under Fusarium verticillioides infection

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
The final leaf length of maize (Zea mays) was reduced due to the pathogenic fungus Fusarium verticillioides infection as a result of increased expression of miR396 in the elongation zone and decreased expression of miR319 in the mature zone of maize leaves, leading to antagonistic regulation of the expression of the GRF15 and TCP38, respectively ...
