Abstract
Lipid peroxidation is a physiological indicator of both biotic and abiotic stress responses, hence is often used as a biomarker to assess stress-induced cell damage or death. Here we demonstrate an easy, quick and cheap staining method to assess lipid peroxidation in plant tissues. In this methodology, Schiff’s reagent, is used to assay for membrane degradation. Histochemical detection of lipid peroxidation is performed in this protocol. In brief, Schiff’s reagent detects aldehydes that originate from lipid peroxides in stressful condition. Schiff’s reagent is prepared and applied to plants tissue. After the reaction, plant tissue samples are rinsed with a sulfite solution to retain the staining color. From this analysis, qualitative visualization of lipid peroxidation in plant tissue is observed in the form of magenta coloration. This reagent is useful for visualization of stress induced lipid peroxidation in plants. In this protocol, Indica rice root, Assam tea root and Indian mustard seedlings are used for demonstration.

Background
Oxidative stress induced by both biotic and abiotic stress factors leads to lipid peroxidation. The peroxidation of unsaturated lipids in membrane is the most apparent symptom of oxidative stress. Lipid peroxidation is a deleterious process in plants, which affects membrane properties, causes protein degradation and limits the capacity of ionic transport, ultimately triggering the cell death process (Yamamoto et al., 2001). Malondialdehyde (MDA) content, which is a byproduct of lipid peroxidation process was found to be enhanced in rice (Ma et al., 2012; Awasthi et al., 2017), Salvinia (Mandal et al., 2013), pea (Yamamoto et al., 2001), Soyabean (Cakmak and Horst, 1991; Du et al., 2010), Indian mustard (Saha et al., 2016) on exposure to stress. The reactive oxygen species (ROS) associated with oxidative stress acts on membrane lipids to decrease membrane stability. Thus making the study of lipid peroxidation an important parameter and our protocol offers a very rapid method for the study. Schiff’s reagent reacts with aldehyde functional group of MDA to give the magenta coloration, thus acting as a key determinant of lipid peroxidation in plant tissues.
