Fusarium wilt caused by Fusarium oxysporum f.sp. Lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. In order to increase the tolerance to this disease, a triple structure containing PR1, chitinase and glucanase genes controlled by 35S promoter was transferred to tomato. Eight days after planting on pre-culture me...

BACKGROUND Tomato spotted wilt virus (TSWV) has a very wide host range, and is transmitted in a persistent manner by several species of thrips. These characteristics make this virus difficult to control. We show here that the over-expression of the mitochondrial alternative oxidase (AOX) in tomato and petunia is related to TSWV resistance. RESULTS The open reading frame and full-length sequen...

A DNA cassette containing an Arabidopsis C repeat/dehydration-responsive element binding factor 1 (CBF1) cDNA and a nos terminator, driven by a cauliflower mosaic virus 35S promoter, was transformed into the tomato (Lycopersicon esculentum) genome. These transgenic tomato plants were more resistant to water deficit stress than the wild-type plants. The transgenic plants exhibited growth retarda...

In an attempt to improve stress tolerance of tomato (Lycopersicon esculentum) plants, an expression vector containing an Arabidopsis C-repeat/dehydration responsive element binding factor 1 (CBF1) cDNA driven by a cauliflower mosaic virus 35S promoter was transferred into tomato plants. Transgenic expression of CBF1 was proved by northern- and western-blot analyses. The degree of chilling toler...

Salinity stress affects morpho-physiological and biochemical traits of plants. The transgenic Bt plants play a significant role in pest control, but their response and ability to cope with environmental stresses still need to be evaluated. Therefore, effect of salinity stress at 0, 50, 100, 150, and 200 mM on morphological, physiological, and molecular traits of T3 transgenic tomato plants cont...

abiotic stress such as cold and drought has adverse effects on plants growth and development. abiotic stress resistance is one of the most important goals in plant breeding. this goal can be achieved through transcription factor gene transfer to plants. recent studies show many successes in improving abiotic stress resistance by use of transcription factor gene transfer. the objective of the re...

Tomato polygalacturonase is a cell wall enzyme secreted in large amounts during tomato fruit ripening. Polygalacturonase is synthesized as a glycoprotein precursor that undergoes numerous cotranslational and post-translational processing steps during its maturation, yielding three isozymes in tomato fruit, PG1, PG2A, and PG2B. To investigate the physiological roles of the three isozymes and the...

Tomato is an important economic crop with nutritional and scientific value for study. Due to its agronomic importance and sensitivity to biotic and abiotic stresses, using new methods in breeding this crop is necessary. In this study, the effects of some factors, such as pre-cultivation time (1, 2, 3 and 4 days), Agrobacterium concentration (OD600nm = 0.4, 0.6, 0.8, and 1), inoculation time (5,...
