Title

MOLECULAR AND BIOCHEMICAL ANALYSIS OF OXIDATIVE STRESS AND UV-B RADIATION IN BRASSICA NAPUS

Pages

REACTIVE OXYGEN SPECIES (ROS)Q3

Abstract

 Production of Reactive Oxygen Species (ROS) has an important role in GENE EXPRESSION and metabolism at cellular levels. High concentrations of ROS lead to phytotoxicity, and may oxidase biological molecules such as DNA, proteins and lipids. In this study, the biochemical links and GENE EXPRESSION between senescence and ROS levels was investigated during senescence and in responseto stress in BRASSICA NAPUS. Experimental treatments (oxidative treatments) were 3-Amino 1, 2, 4- Triazole (3-AT), Silver Nitrate (AgNO3) and Ultraviolet-B (UV-B) radiation as well as three combined treatments: pre-treatment of Ascorbic-Acid followed by the each of the above treatments. The results showed, the effect of oxidative treatments both in detrimental effects on physical appearance and in changes in chlorophyll and TBARM (indicating oxidative levels in cell) was reduced by pre-treating the tissues with ascorbic acid. According to northern blot analysis results, it was similar to changes in senescence-enhanced and defense GENE EXPRESSION, indicating that oxidative treatments induced GENE EXPRESSION by increasing ROS levels. This result implies the importance of ROS in genetic signal pathways.
