Abstract

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 Alternaria alternata culture, were 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 A. alternata by the matern form.
