The Circadian Oscillator Affects Both Glutathione Homeostasis and Its Response to Salt Stress in Arabidopsis thaliana

Plant, Cell &Environment, Volume 49, Issue 8, Page 5421-5434, August 2026.
ABSTRACT Glutathione, including reduced glutathione (GSH) and oxidized glutathione (GSSG), is the major non‐protein thiol‐based redox buffer. There are diurnal rhythms in total glutathione level and in this work, we investigate whether these oscillations might be indicative of circadian regulation of total glutathione homeostasis.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, Volume 49, Issue 8, Page 5849-5865, August 2026.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

COL2-dependent photoperiodic floral induction in Nicotiana sylvestris seems to be lost in the N. sylvestris × N. tomentosiformis hybrid N. tabacum

Frontiers in Plant Science
IntroductionPlants are sessile organisms that maximize reproductive success by adapting to their environment. One of the key steps in the reproductive phase of angiosperms is flower development, requiring the perception of multiple endogenous and ...

RNA interference in crop protection: opportunities and challenges during the transition to commercialization

Pest Management Science, Volume 82, Issue 7, Page 5971-5986, July 2026.
RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.

Simulating long‐term soil carbon sequestration and wheat productivity under biochar amendments in saline‐irrigated sandy soils

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract Improving carbon sequestration in sandy soils under saline irrigation is essential for sustaining agricultural productivity in marginal environments. This study addressed two key questions: (i) can biochar, alone or combined with organic amendments, enhance soil carbon storage and fertility under saline irrigated?

Seed Floras in Seabird Nests and the Possibility of Adhesion to Seabird Feathers via Their Nests

Plant Species Biology, Volume 41, Issue 4, July 2026.
Nests are important links between seabirds and plants, and are thought to initiate epizoochory of seabirds. 24 seed species were found in pelagic seabird nests, and 16 species of them had the potential to adhere to seabirds. Our finding indicates an overlooked pathway for the long distance dispersal of plants; epizoochory mediated by nests.

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).
