Reactive oxygen species (ROS) generation in tomato plants by Ralstonia solanacearum infection and the role of hydrogen peroxide (H2O2) and nitric oxide in tomato bacterial wilt control were demonstrated. During disease development of tomato bacterial wilt, accumulation of superoxide anion (O2 (-)) and H2O2 was observed and lipid peroxidation also occurred in the tomato leaf tissues. High doses ...

Companion cropping with potato onions (Allium cepa var. agrogatum Don.) can enhance the disease resistance of tomato plants (Solanum lycopersicum) to Verticillium dahliae infection by increasing the expressions of genes related to disease resistance. However, it is not clear how tomato plants physiologically respond to V. dahliae infection and what roles sulfur plays in the disease-resistance. ...

Tomato wilt disease is one of the most destructive fungal diseases infecting tomato plants in Egypt. The caused by

conclusions decreases of tc, ldl and tg may be related to tomato antioxidant effect. this course in human required more investigations. results results showed that in chol group, all lipids increased significantly (p < 0.05) except hdl compared to the control group. tomato and tomato paste supplementation decreased tc, ldl and tg concentration significantly (p < 0.05) compared to chol group. to...

Biological control agents are useful components in the enhancement of plant disease resistance and improvement of soil properties. Effect of biological control agents (BCAs) as a disease control method in plants is hampered by their vulnerability to environmental and edaphic conditions. This study entailed the use of chitosan-silica nanocomposites for delivery of BCAs. Effect of BCAs-nanocompos...

Taiwanese isolates of Phytophthora infestans were examined for mating types and pathogenicity to tomato and potato. A total of 70 isolates, including 68 isolates from tomato and 2 isolates from potato, from six counties of Taiwan were all A1 mating type. Three tomato isolates of P. infestans caused only leaf blight of tomato, while two isolates obtained from potato were able to cause the diseas...

Tomato (Solanum lycopersicum L.) is susceptible to many diseases including bacterial speck caused by Pseudomonas syringae pv. tomato. Bacterial speck disease is a serious problem worldwide in tomato production areas where moist conditions and cool temperatures occur. To enhance breeding of speck resistant fresh-market tomato cultivars we identified a race 0 field isolate, NC-C3, of P. s. pv. to...

Producing tomato is a daunting task as the crop of tomato is exposed to attacks from various microorganisms. The symptoms of the attacks are usually changed in color, bacterial spots, special kind of specks, and sunken areas with concentric rings having different colors on the tomato outer surface. This paper addresses a vision sensing based system for tomato quality inspection. A novel approac...
