The Role of Enzymes in Plant Responses to Stress Factors

In the face of an escalating ecological crisis, environmental stress factors exert a significant influence on plant vegetation.This study explores the adaptation mechanisms of plants to new conditions while maintaining their development in the presence of stress factors.Under unfavorable environmental conditions, plants experience stress that may either lead to their complete destruction or to their adaptation to these conditions.Stress in plants results in a weakening of their normal life activity.Thus, the process that begins with a weakening of biosynthesis at the cellular level extends to tissues and organs, eventually disrupting the plant's normal life processes and potentially leading to death.The present research examines ezyme changes in the green leaves of bean plants (Phaselus vulgaris L.), whose seeds were exposed to gamma radiation at doses ranging from 1-300 Gy prior to sowing.To analyze the response of the bean plant, the activities of two enzymes, Pyruvate kinase (PK) and Oxalate Decarboxylase (OAD) were investigated.It was observed that the activity of PK and OAD varies depending on both the developmental stage of the plants (depending on time) and the radiation dose, compared to the control sample.Thus, while the development of plants is accelerated at a certain level of radiation dose, the growth of plants starts to slow down as the dose increases.
