دور البرولين في ظل البيئات المتغيرة دراسة مقارنة و مراجعة

Abstract

This study aims to understand the role of proline under changing environmental conditions and to determine its effectiveness in mitigating the damage caused by abiotic stresses such as heat, salinity, and drought. Numerous studies have shown that proline plays a vital role in helping plants adapt to various environmental stresses. Proline functions as a protective osmolyte by enhancing osmotic balance and preventing water loss, thereby strengthening the plant's ability to withstand harsh conditions. Under heat and salt stress, proline accumulates significantly in roots and leaves, contributing to cellular protection against oxidative damage and improving photosynthetic efficiency. During drought stress, proline supports water balance and reduces the damage resulting from decreased cellular water content. Additionally, proline interacts with other compounds, such as cobalt sulfate, to enhance biological responses, reduce oxidative stress, and promote nutrient uptake and osmotic adjustment. Overall, proline serves as a crucial biomarker for assessing plant tolerance to various stresses and plays an important role in supporting plant recovery and resilience under adverse environmental conditions.
