Use of photochemical catalyst-treated water for induction of PR genes in higher plants

Abstract

Recently, we have been engaged to development of novel system for preparation of water rich in reactive oxygen species (ROS), by passing the water through the photochemical apparatus equipped with thin alumina-coated aluminum fibers further coated with titania, UV-A lamps & ultrasonic devices. Data suggested that the processed water contained superoxide, singlet oxygen & hydroxy radicals. In the present study, we treated the growing plants & leaf disks of tomato, tobacco and other species. We observed that expression of PR-genes & other defense & redox-related genes by treatment with photochemically processed water.
