非生物胁迫对生态系统和作物产量产生巨大影响，全球变暖可能导致更频繁和更强烈的胁迫。然而，由于潜在的信号通路的复杂性，以及逆境在自然界中经常以组合的方式发生，我们对植物如何适应非生物逆境的认识仍然缺乏。在这里，我们使用具有最小调节网络冗余的植物，多形地豆，研究了7种非生物胁迫如何单独和联合影响表型，基因表达和生物途径的活性。令人担忧的是，我们没有看到模式生物之间对非生物胁迫的基因表达守恒的证据，这表明每个物种都有独特的策略来应对非生物胁迫。有趣的是，我们观察到某些压力能够抑制其他压力，而特定的组合可以阐明新的转录组反应。最后，我们提供了两个在线数据库来研究Marchantia的非生物胁迫响应和昼夜基因表达数据。
Abiotic stress has a dramatic impact on ecosystems and the yield of crops, and global warming will likely result in more frequent and intense stresses. However, due to the complexity of the underlying signalling pathways and the fact that stresses often occur in combinations in nature, our knowledge of how plants acclimatize to abiotic stress is still lacking. Here, we used a plant with minimal regulatory network redundancy, Marchantia polymorpha, to study how seven abiotic stresses alone and in combination affect the phenotype, gene expression, and activity of biological pathways. Worryingly, we see no evidence of conservation of gene expression to abiotic stress between model organisms, suggesting that each species develops unique strategies to cope with abiotic stress. Interestingly, we observed that certain stresses are able to suppress others, while specific combinations can elucidate novel transcriptomic responses. Finally, we provide two online databases to study abiotic stress responses and diurnal gene expression data in Marchantia.
