Chloroplast f and m Thioredoxins Discovered in Nonphotosynthetic Tissues
Date:10/16/2007

and m TRX types may function in redox regulation or in protection against oxidative damage. Other studies have shown that TRXs can function directly as antioxidants or in signaling pathways that sense reactive oxygen species and can thus protect plants against oxidative damage.

Sahrawy and her team are now concentrating on analyzing the specific functions of these TRXs in different stages of plant development and under different physiological conditions. Knowledge of the diverse functions of these versatile proteins may be important in engineering drought and heat tolerant plants and in helping to protect plants against oxidative damage under stress conditions.
