Proteome Analysis of the ROF-FKBP Mutants Reveals Functional Relations among Heat Stress Responses, Plant Development, and Protein Quality Control during Heat Acclimation in Arabidopsis thaliana.

ABSTRACT: In the present study, a differential screening following heat stress acclimation was performed in Arabidopsis thaliana WT and ROF-FKBP mutated plants using mass spectrometry, and the results were used to understand and analyze the effect of the ROF PPIases during thermotolerance acquisition in plants. Our data highlight the central role of these two PPIases in heat stress and point to their direct or indirect effect on other proteins participating in cellular functions such as protein folding and quality control, cell division, photosynthesis, and other metabolic and signaling processes. Specifically, the heat stress response, protein folding, and protein ER processing pathways are enhanced following a 37 °C acclimation period independent of the mutation state. However, at 37 °C, an
