Dr. Biancaelena Maserti, Senior Researcher at the Sesto Fiorentino Unit, have been invited to become the guest editor of a Special Issue, titled “Insight into plant response to abiotic stress: the role of Glyoxalase pathway and antioxidant system“, which will be published in the journal Plants (https://www.mdpi.com/journal/plants).
Plant growth and crop productivity are strongly influenced by abiotic stress such as cold, drought, mineral imbalance, heat, ozone.
As a common consequence of plant exposure to abiotic stresses the production of reactive oxygen species (ROS) and methylglyoxal (MG) increase. ROS and MG can react with proteins, lipids and nucleic acids resulting into metabolic dysfunction and death.
To scavenge those toxic compounds plants have a complex network of mechanisms, including the activation of antioxidant enzymes such as SOD, CAT, and those of Halliwell-Asada Cycle to control ROS levels. Glyoxalase system directly detoxify MG or can play a role in oxidative stress response by maintaining gluthathione (GSH) homeostasis.
Several studies have showed that increased plant resistance to abiotic stresses are often correlated with high levels of glyoxalase and antioxidant enzyme activity.
This Special Issue will collect novel research papers and original reviews focusing on the response of glyoxalase system and antioxidant enzymes in plants exposed to abiotic stress, with a particular attention to their possible combined regulatory roles in alleviating oxidative damage and increase plant resistance to abiotic stress.
