The study was focused on changes in protein content and
peroxidase activity in pea roots subjected to infection with Rhizobium
leguminosarum and to low temperature. The amount of protein and
peroxidase activity were shown to change in the course of interaction
with nodular bacteria and to depend on the temperature and root zones
susceptibility to rhizobia. It was concluded that changes in the
content of soluble protein and peroxidase activity witness adaptation
changes in pea seedlings, which facilitate normal course of metabolic
processes and ensure regulation of plant interaction with Rhizobium in hypothermal conditions.
Key words: peroxidase activity,
legume-rhizobial symbiosis, hypothermia, soluble protein
