N2  - Background: Invasive alien species (IAS) are broadly distributed all over the world by disturbing or reducing the growth and development of native vegetation. Lantana camara is basically a noxious weed and have a potential to invade a region's indigenous vegetation. Even after knowing all its harmful effects, there has been a little research on various mechanisms followed by this plant to harm the plant species. Results: Random sampling was performed to take plant samples without any bias, to study various mechanisms carried out in plant species. Chemical fingerprinting of samples were then performed in various abiotic stress conditions (cold and hot) to study changes in L. camara under these stressful conditions in order to find the reason behind the invasiveness of this plant species. Stress indicator like malondialdehyde (MDA)/lipid peroxidation was also performed and increased lipid peroxidation during both extremities showed that plant is experiencing oxidative stress. ROS imaging was performed on the leaves of L. camara, which also showed rise in ROS staining during extreme conditions. Elevated peaks (major and minor) and detection of secondary metabolites like glycine betaine in chemical fingerprinting observed under stressful conditions showed that plant may produce some increased level of metabolites in stress conditions that might play a role in minimizing the oxidative stress that plant is facing. Conclusions: On the behalf of obtained results, it can be assumed that Lantana camara has the capability to survive in or tolerate extreme environmental abiotic stress conditions by producing or agglomerating various stress-reducing metabolites.
