Manipulating plant oxygen sensing through NCO substitution reveals trade-offs between growth and flooding tolerance
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...

Engineering reduced activity in the oxygen-sensing Arabidopsis thaliana plant cysteine oxidase 4 enzyme results in improved flood resilience
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...
