It has been shown that a tomato cultivar Gruntovy Gribovsky 1180 transformed with pea lectin gene (psl) has been shown to form a stable associative symbiosis with a Rhizobium leguminosarum bacteria that have fungistatic activity. This provides the protection of the plant root system from the phytopathogen Fusarinm oxysporum f. sp. lycopersici. The survival of the plants transgenic for the psl gene and incubated with rhizobia made up 81.5% after the fungal contamination. The analogous value for the nontransgenic plants was equal to 47.6%.

 

Key words:  fungistatic activity,  pea lectin,  rhizobia,  transgenic tomato.
