Molecular cloning of glutathione reductase from Oryza sativa, demonstrating its peroxisomal localization and upregulation by abiotic stresses

Acta Biochim Pol. 2023 Jan 8;70(1):175-181. doi: 10.18388/abp.2020_6441.

Abstract

Abiotic stress is a major constraint on crop productivity and in the agricultural field, multiple abiotic stresses act synchronously leading to substantial damage to plants. A common after-effect of abiotic stress-induced damage in plants is an increased concentration of reactive oxygen species (ROS) leading to oxidative damage. Glutathione reductase (GR) plays a significant role in curtailing ROS. Apart from the GR enzyme, the peroxisome as an organelle also plays a significant role in ROS homeostasis. Here, we report a peroxisome localized GR, whose expression was found to be upregulated by various abiotic stresses. The in silico analysis also revealed that the peroxisomal localization of GR could be a common phenomenon in angiosperms, suggesting that it could be a suitable candidate against abiotic stress combinations.
