Peroxidase activity from callus cells, fruit and root of tomato plant (Lycopersicon esculentum)
Jamaican Journal of Science and Technology
Date of Publication
The activity of peroxidase was examined in callus cells (undifferentiated plant cells), the fruit and root of the tomato plant. Activity was highest in the callus cells, followed by the roots and then the fruit. Callus cells are much more susceptible to attack by pathogens than differentiated plant cells, hence a higher activity is expected in callus cells than in differentiated cells. The roots also had appreciable enzyme activity - more that the fruit but less than the callus cells. The major function of this enzyme is similar to that of extensin peroxidase....
