Due to climate change, there are increasing events of heavy rain and flooding, which can cause hypoxia (lack of oxygen) and the release of toxic iron concentrations in the soil.
Why can some plant species survive this stress better than others? Which molecular mechanisms are responsible for stress tolerance? Are there markers with which stress-tolerant varieties can be selected more quickly?
Our new publication, which was created in cooperation with the University of Vienna (Austria), provides answers to some of these questions. The study pursues a systems biological approach to show which functions membrane-bound peroxidases fulfill regarding oxidative stress, the formation of aerenchyma and the remodeling of the cell wall. Their localisation in microdomains and the interaction with NADPH oxidases are discussed.
