• Heterologous OsTPX expression increased the ability of the transgenic yeast cells to adapt and recover from reactive oxygen species (ROS)-induced oxidative stresses, such as a reduction of cellular hydroperoxide levels in the presence of hydrogen peroxide and menadione, by improving redox homeostasis
• These results suggest that heterologous OsTPX expression increases acquired tolerance to ROS-induced oxidative stress by improving cellular redox homeostasis and improves fermentation capacity due to improved cell survival during fermentation, especially at a high temperature
• Furthermore, high OsTPX expression improved the fermentation capacity of the yeast during glucose-based batch fermentation at a high temperature (40 degrees C) and at the general cultivation temperature (30 degrees C)
• In this study, a putative chloroplastic 2-Cys thioredoxin peroxidase (OsTPX) was identified by proteome analysis from leaf tissue samples of rice (Oryza sativa) seedlings exposed to 0
• The alcohol yield in OsTPX-expressing transgenic yeast increased by approximately 29 % (0
• We found that OsPRX2 was localized in the chloroplast
• OsPRX2 contributes to stomatal closure and improves potassium deficiency tolerance in rice.
• In this study, a rice homologue gene of At2-CysPrxB, OsPRX2 was investigated aiming to characterize the effect of 2-Cys Prxs on the K(+)-deficiency tolerance in rice
• Overexpressed OsPRX2 causes the stomatal closing and K(+)-deficiency tolerance increasing, while knockout of OsPRX2 lead to serious defects in leaves phenotype and the stomatal opening under the K(+)-deficiency tolerance
• Detection of K(+) accumulation, antioxidant activity of transgenic plants under the starvation of potassium, further confirmed that OsPRX2 is a potential target for engineering plants with improved potassium deficiency tolerance
