BAG9 Confers Thermotolerance by Regulating Cellular Redox Homeostasis and the Stability of Heat Shock Proteins in Solanum lycopersicum.

BAG9 Interacts with Hsp20s and Maintains Hsps Stability under Heat Stress We next identified BAG9-interacting proteins by applying yeast two-hybrid screens. To further investigate whether heat-induced oxidative stress caused the oxidation of functional proteins, SDS-PAGE was used to analyze protein oxidation among proteins isolated from total proteins. Involvement of BAG9 in Tomato Thermotolerance Transcript analysis of 10 I SlBAGs i under heat stress was conducted to determine whether heat stress induced BAG gene expression. Thus, BAG9 played a crucial role in response to heat stress by regulating cellular redox homeostasis and the stability of heat shock proteins. [Extracted from the article]
