Why plant cells need heme: Hidden signal reshapes photosynthesis gene control

For plants, light is an important environmental factor not only as a source of energy for photosynthesis, but also as a signal for capturing environmental information.

Copper-based sensor explains key defense signaling in stressed plants

Researchers at the Institute of Transformative Bio-Molecules (WPI-ITbM), Nagoya University, together with collaborators from RIKEN Center for Sustainable Resource Science (RIKEN CSRS) and The University of Osaka, have uncovered a previously unknown mechanism by which plants detect hydrogen peroxide (H₂O₂), a key signaling molecule involved in stress responses and immunity. Published in Nature Communications, the study reveals that plants rely on a copper-dependent sensing system, rather than the previously assumed cysteine-based mechanism, to perceive reactive oxygen species (ROS).

Plant stress and unique cAMP signaling

The molecule cAMP, which plays essential roles in mammalian cells, is less well understood in plants. In a new Science Advances paper, researchers from the Institute of Science and Technology Austria (ISTA) and international collaborators demonstrate that plants use two forms of cAMP in parallel to regulate normal cellular processes and respond to stress, while maintaining crosstalk between them. That crosstalk provides redundancy, so that if one fails, the other can compensate, allowing plants to respond more robustly to a wider range of environmental factors.

Calcium Channels and Intracellular Calcium Signaling: An Early Plant Defense Response against Pests and Pathogens

This review explores the molecular mechanisms underlying Ca2⁺ channel activation, the spatiotemporal dynamics of intracellular Ca2⁺ fluxes, and their crosstalk with phytohormones and other signaling pathways.

Weak OsBRI1 allele in Zhonghua 11 as genetic tool for brassinosteroid signaling research in rice

Zhonghua 11 and Taichung 65 exhibit distinct physiological and molecular responses to brassinosteroids despite their close japonica relationship. A near-isogenic line, d61-zh11, was developed to transfer the classical brassinosteroid (BR)-insensitive mutation into a modern functional genomics background.

Integration of NO and H2S signaling in higher plants

Nitric oxide (NO) and hydrogen sulfide (H2S) have gained significant importance in plant biochemistry and physiology due to their versatile signaling roles.

Fingers for Signaling? A Possible Role of Stromules in Intracellular Communication

In the current study, we tested two alternative hypotheses: stromules might channel metabolic flux from plastids to peroxisomes during jasmonate biosynthesis, or they might serve as conduits for plastid–nucleus retrograde signaling.

A hormone-linked switch helps tea plants withstand cold

Cold snaps can restrict tea growth, damage young leaves, and reduce crop yield and quality, yet the molecular links between hormone signaling and cold defense have remained unclear.

HHO5 orchestrates dose-dependent feedback regulation of organic versus inorganic nitrogen signaling in Arabidopsis

Important regulators of plant N-responses include HRS1 HOMOLOG (HHO) transcription factors (TFs); yet, their redundant repressive mode of action hinders functional analyses.

The BZR1-BLH1-PIF4 feedback module acts as a molecular amplifier for precise thermomorphogenesis in Arabidopsis

Findings define a BZR1-BLH1-PIF4 regulatory axis that modulates the BZR1-PIF4-auxin-BR-BZR1 positive feedback loop, ensuring a balanced thermomorphogenic response to HT.

Plant-to-plant signaling: building networks for resilience to stress, or merely eavesdropping?

The review discusses how improved plant-to-plant and plant-to-microbiome signaling, achieved via research, intervention, and altered practices, can be used to form resilient plant communities that will help us shape our environment and successfully address some of our current and future anthropogenically generated critical challenges.
