Bacteria deactivate the protein synthesis of host cells to hamper immune reactions. This insight could aid in the development of more resistant plants.

Experiments in Arabidopsis demonstrate that group VII ethylene response factors show differential responses to different stimuli, enabling plants in flood-prone environments to adapt to both submergence-induced hypoxia and reoxygenation upon desubmergence.

Hydrogen sulfide (H₂S) is a gaseous molecule historically regarded as toxic. Nevertheless, increasing evidence has brought to light important physiological roles in both animals and plants. In plants,...

Plant cysteine oxidases (PCOs) are oxygen-sensing enzymes that play an important role in plant responses to low oxygen (hypoxia). PCO-catalysed dioxygenation of the N-terminal Cys of substrates, inclu...

The oxygen-dependent degradation of Ethylene Response Factors VII (ERFVIIs) through the N-degron pathway is central to regulating the transcriptional responses to hypoxia in vascular plants. Plant Cys...

Short summary:This study investigates the evolution of the low-oxygen response in land plants mediated by group VII Ethylene Response Factors (ERFVIIs). We identified conserved transcriptional signatu...

SCF–FBXO31 scans proteins for C-terminal amidation and marks them for subsequent proteasomal degradation.

The diverse aspects of hypoxia. The size of the oxygen bubble correlates with concentration. This collection highlights the importance of hypoxia for plant development and environmental adaptation such as during flooding, in compacted or poorly aerated soils, high altitudes, and within meristematic tissues.

Novel biosensors and concepts from engineering biology expand the toolbox for plant low oxygen biology research

Abstract. Our understanding of how low oxygen (O2) conditions arise in plant tissues and how they shape specific responses has seen major advancement in re
