A stress recovery signaling network for enhanced flooding tolerance in Arabidopsis thaliana

Flooding is a sequential stress where tolerance is strongly dependent on viability underwater and during the post-flooding period. In the Arabidopsis thaliana accessions Bay-0 and Lp2-6, different rates of submergence recovery correlate with submergence tolerance and fecundity. A genome-wide assessment of ribosome-associated transcripts in Bay-0 and Lp2-6 revealed a signaling network regulating recovery processes following flooding to hasten the return to pre-stress homeostasis.渍涝胁迫是一种序贯性胁迫，其耐受性强弱高度依赖于植株在淹水阶段及涝后恢复期的存活活力。在拟南芥（Arabidopsis thaliana）生态型Bay-0与Lp2-6中，不同的淹涝恢复速率与淹涝耐受性及繁殖力显著相关。针对Bay-0与Lp2-6的核糖体结合转录本（ribosome-associated transcripts）开展全基因组分析后，研究人员揭示了一套调控涝后恢复过程、加速植株恢复至胁迫前内稳态的信号网络。
