Enhancing crop yield by using Rubisco activase to improve photosynthesis under elevated temperatures

Area of Science:

• Agricultural Science
• Plant Physiology
• Biochemistry

Background:

• Global population growth necessitates increased agricultural productivity.
• Elevated temperatures and heat stress negatively impact plant biomass and crop yield.
• Rubisco activase (RCA) thermo-sensitivity hinders photosynthesis under heat stress.

Purpose of the Study:

• To review the need for improved RCA thermo-tolerance for crop yield under climate change.
• To discuss RCA structure, regulation, and limitations at elevated temperatures.
• To provide a perspective on RCA research for enhancing crop yield.

Main Methods:
