Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops grown in the world, next to potato. It is used as a fresh vegetable and also can be processed and canned as a paste, juice, sauce, powder or as a whole (Barone and Frusciante, 2007). The ripe fruits are good source of vitamin A, B and C which add wide varieties of colour and flavour to the food. Recently, it started gai...

Fifty fungal isolates were sampled from diseased tomato plants as result of a survey conducted in seven tomato crop areas in Algeria from 2012 to 2015. Morphological criteria and PCR-based identification, using the primers PF02 and PF03, assigned 29 out of 50 isolates to Fusarium oxysporum (Fo). The banding patterns amplified for genes SIX1, SIX3 and SIX4 served to identify races 2 and 3 of Fo ...

Phytohormones such as salicylic acid (SA), ethylene (ET) and jasmonic acid (JA) play key roles in plant defense following pathogen attack. Involvement of these hormones in plant susceptibility following Fusarium oxysporum (Fo) infection has mostly been studied in Arabidopsis thaliana. However, Fo causes vascular wilt disease in a broad range of crops, including tomato (Solanum lycopersicum). Su...

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...

The vast majority of plant disease resistance (R) genes encode nucleotide binding site-leucine-rich repeat (NBS-LRR) proteins, which specifically determine the plant immune response and have been demonstrated to be targets of several microRNA (miRNA) families. The fungus Fusarium oxysporum f. sp. lycopersici (FOL) causes vascular wilt disease in tomato worldwide. Here, we explored a possible ro...

the present investigation was carried out to isolate and characterize antagonistic bacteria against wilt causing fungal pathogen i.e. fusarium oxysporum, from the rhizosphere of tomato. fifty-six bacterial strains were isolated from the rhizosphere soil samples of healthy tomato fields, collected from different locations of faridabad district, haryana, india. out of these, ten isolates were fou...

Aim. Studying of the influence avermectin-containing polyfunctional preparations Avercom and Nova on enhancement resistance to fusarium wilt tomato plants in vitro. Methods. Tomato were cultivated vitro for 30 days presence 25 μl/l Nova. Analysis was carried out by spraying with a conidia suspension Fusarium oxysporum f. sp. lycopersici F. solani. Resistance has been evaluated 15 after inoculat...

Soilborne fungal pathogens cause devastating yield losses and are highly persistent and difficult to control. During the infection process, these organisms must cope with limited availability of iron. Here we show that the bZIP protein HapX functions as a key regulator of iron homeostasis and virulence in the vascular wilt fungus Fusarium oxysporum. Deletion of hapX does not affect iron uptake ...
