Ethylene-mediated nitric oxide depletion pre-adapts plants to hypoxia stress
Sjon Hartman,Zeguang Liu,Hans van Veen,Jorge Vicente,Emilie Reinen,Shanice Martopawiro,Hongtao Zhang,Nienke van Dongen,Femke Bosman,George W. Bassel,Eric J. W. Visser,Julia Bailey-Serres,Julia Bailey-Serres,Frederica L. Theodoulou,Kim H. Hebelstrup,Daniel J. Gibbs,Michael J. Holdsworth,Rashmi Sasidharan,Laurentius A. C. J. Voesenek +18 more
TL;DR: Hartman et al. show that passive ethylene entrapment during root submergence enhances NO-scavenger PHYTOGLOBIN1, ERFVII stability and promotes subsequent hypoxia tolerance and identifies key regulatory targets for early stress perception that could be pivotal for developing flood-tolerant crops.
Signal Dynamics and Interactions during Flooding Stress.

TL;DR: The production of reactive oxygen species (ROS) in plant cells during flooding and directly after subsidence, during which the plant is confronted with high light and oxygen levels, is characteristic for this abiotic stress.

TL;DR: In this article, the root growth in compacted soil is instead actively suppressed by the volatile hormone ethylene, which acts as an early warning signal for roots to avoid compacted soils, which is relevant to research into the breeding of crops resilient to soil compaction.
The role of ethylene in metabolic acclimations to low oxygen.
TL;DR: It is suggested that ethylene could play an important role in the induction of autophagy and promote reactive oxygen species amelioration, thereby contributing to enhanced survival during flooding, hypoxia, and reoxygenation stress.

Oxygen-dependent proteolysis regulates the stability of angiosperm polycomb repressive complex 2 subunit VERNALIZATION 2
Daniel J. Gibbs,Hannah M. Tedds,Anne-Marie Labandera,Mark Bailey,Mark D. White,Sjon Hartman,Colleen Sprigg,Sophie L. Mogg,Rory Osborne,Charlene Dambire,Tinne Boeckx,Zachary Paling,Laurentius A. C. J. Voesenek,Emily Flashman,Michael J. Holdsworth +14 more
TL;DR: It is shown thatVRN2 is degraded via the N-end rule pathway, which prevents ectopic accumulation of VRN2 in the absence of appropriate environmental stimuli, and a mechanism for post-translational regulation of VRn2 stability is revealed that could potentially link environmental inputs to the epigenetic control of plant development.
