Abstract: | In the present work the responses of β-glucosidase in leaves of tomato plants subjected to various stress factors of both
pathogenic (fungi, bacteria, viruses) and abiotic origin (heat shock) were studied. Biochemical and cytochemical methods were
applied. It was established that an increase of β-glucosidase activity is induced uniquely by fungal pathogens. The cytochemical
tests confirm the finding. Hence, the conclusion can be drawn that β-glucosidase response is a specific character of fungal
pathogenesis in tomato; probably, the enzyme is involved in plant — fungi recognition. The data are in accordance with our
previous results on tobacco and wheat — stress stimuli systems. |
