Comparative proteomics analysis of the responses to cigarette smoke particulate matter in six plant species leaves

Abstract

Abstract Phytoremediation has been recognized to reduce particulate matter (PM) concentration in the air. Plant stress response plays a crucial role in PM removal. In this study, six plants including ornamental and perennial plants were exposed to PM from cigarette smoke for 24 hours. Ornamental plants were Calathea makoyana, Sansevieria trifasciata, and Zamioculcas zamiifolia, where perennial plants Bauhina purpurea, Tectona grandi, and Wrightia religiosa. The initial concentration of PM was 300–320, 400–450, and 500–530 µg m− 3 for PM1.0, PM2.5, and PM10, respectively. The plant response of each plant was compared to determine the plant response of each group and plant against PM stress. The results showed that all plants have different protein expressions. Ornamental plants showed more enrichment in photosynthesis and antioxidant enzymes, whereas perennial plants were in photosynthesis, an antioxidant enzyme, and carbon metabolism. The results suggest the plant response of each plant of an ornamental and perennial plant. This proteomics approach was useful for future studies, especially for phytoremediation.
