Peran Chaperone Pada Tumbuhan: Mini Review

Abstract

Plants respond to various conditions in the surrounding environment, whether favorable conditions or vice versa. Abiotic and biotic factors affect plant responses such as temperature, humidity, salinity, insects and pathogens such as viruses and bacteria. Plants have a defense system in tolerancing stress from the surrounding environment, for example heat shock protein (HSP) is a chaperone protein that plays a role in plant defenses when experiencing stress to the temperature. HSP is classified into six families based on their molecular weight, namely HSP100, HSP90, HSP70, HSP60, HSP40, and small HSP. Each has a role in maintaining the stability of plant metabolism. HSP is especially important for correct protein refolding, preventing degradation and denaturation of protein. Key words: plants; chaperone; heat shock protein; refolding; protein denaturation.

Effect of Temperature on the Physiological Response of Enhalus acoroides Seedlings

“…Plants have defences to adapt to high-temperature stress by developing various mechanisms, including the role of Heat Shock Protein (HSP), and under high temperatures, the production of Reactive Oxygen Species (ROS) also increases, and plants must activate their antioxidant defences and protect themselves from stress hot (Purnama et al, 2019). Plant stress due to high temperature, salinity and others can trigger plant defences, especially through molecular mechanisms through protein formation (Wasilah et al, 2019).…”
