Forewarned is forearmed: rice plants develop tolerance to post-anoxia during anoxic conditions by proteomic changes.

ABSTRACT:

Introduction

In the absence of oxygen (anoxia), plants suffer from an energy shortage. Subsequent return to normoxia could exacerbate the obtained damage through severe oxidative stress. Thus, in nature, post-anoxia is a broad combination of stressors. The efficient recovery after oxygen depletion can occur only by the activation of defensive systems.

Methods

In this study, we analyzed the impact of anoxia and re-aeration on tolerant rice at a proteomic level using two-dimensional gel electrophoresis followed by mass spectrometry. We further used bioinformatic predictions to reveal transcription factors modulating stress-induced gene expression.

Results

Mass spectrometry revealed 82 spots corresponding to 13 and 8 unique proteins in shoots and roots, respectively. Spo
