The peroxidases, as oxido-reducing enzymes and PR proteins, and esterases of hydrolytic enzymes are deeply involved in
the defensive reactions of plants to various unfavorable factors. There were not found some data on the role of maternal
factor in the response of these enzymes to fungal pathogens. By analyzing the activity of peroxidases and esterases in the seeds
of parental forms - Gloria, Jubiliar, Atlasn?i and reciprocal hybrids F1 varieties, treated with
found differences in patterns of the enzyme expression, based on genotype and variant. Thus, in F1 hybrid seeds Gloria x
Jubiliar, in control, the peroxidases activity was much lower than the other analog. The activity of peroxidases in the F1 hybrid
seeds Atlasn?i x Gloria was much higher than in F1 Gloria x Atlasn?i, both in control and with culture filtrate. Compared with
peroxidases, esterases patterns of expression, depending on the genotype and variation, were more distinguished based on
the presence and the intensity of the different isoforms. So, regulating of the genes expression which encodes peroxidases and
esterases is a way to control the reaction of the tomatoes to
by the matern form.
