ABSTRACT
This study is conducted to examine the effects of Tomato yellow leaf curl virus (TYLCV) geminivirus
infection on nitrogenous constituents, proline, nitrate reductase, phenylalanine ammonia lyase activity,
total phenol content, glutathione, lipid peroxidation (MAD) and also activities of superoxide dismutase
(SOD; EC 1.15.1.1), peroxidase (POD; EC 1.11.1.7) and catalase (CAT; EC 1.11.1.6) were estimated in
both healthy and infected tomato plants. Infected plants showed reduction in total protein and nitrate
reductase. Besides these, TYLCV infection caused an increase of total-N, amino-N, proline content in
leaves, stems and roots, and also increase of phenylalanine ammonia lyase activity, total phenol
content, glutathione, lipid peroxidation and activities of antioxidant enzymes in leaves were detected
compared with healthy plants.
