“…To survive and regulate different responses under waterlogging stress, plants modulate numerous morphological, transcriptional and metabolic changes (Bailey-Serres and Colmer, 2014;Bailey-Serres and Voesenek, 2008;Lee et al, 2011;Nanjo et al, 2011;Narsai et al, 2009;Zou et al, 2010). Anaerobic pathways, such as ethanolic fermentation and glycolysis coupled with nicotinamide adenine dinucleotide (NAD) regeneration, respond to fulfil adenosine triphosphate (ATP) needs under waterlogging stress, and adaptive traits such as aerenchyma and adventitious root formation are induced to promote gas diffusion (Colmer and Voesenek, 2009).…”

SummaryGroup VII ethylene response factors (ERFVIIs) play important roles in ethylene signalling and plant responses to flooding. However, natural ERFVII variations in maize (ZmERFVIIs) that are directly associated with waterlogging tolerance have not been reported. Here, a candidate gene association analysis of the ZmERFVII gene family showed that a waterlogging‐responsive gene, ZmEREB180, was tightly associated with waterlogging tolerance. ZmEREB180 expression specifically responded to waterlogging and was up‐regulated by ethylene; in addition, its gene product localized to the nucleus. Variations in the 5ʹ‐untranslated region (5ʹ‐UTR) and mRNA abundance of this gene under waterlogging conditions were significantly associated with survival rate (SR). Ectopic expression of ZmEREB180 in Arabidopsis increased the SR after submergence stress, and overexpression of ZmEREB180 in maize also enhanced the SR after long‐term waterlogging stress, apparently through enhanced formation of adventitious roots (ARs) and regulation of antioxidant levels. Transcriptomic assays of the transgenic maize line under normal and waterlogged conditions further provided evidence that ZmEREB180 regulated AR development and reactive oxygen species homeostasis. Our study provides direct evidence that a ZmERFVII gene is involved in waterlogging tolerance. These findings could be applied directly to breed waterlogging‐tolerant maize cultivars and improve our understanding of waterlogging stress.

“…Understanding the different mechanisms by which plants adapt and respond to environmental stresses may lead to novel strategies for crop improvement. Flooding, a compound abiotic stress that often leads to cellular hypoxia and energy depletion, is responsible for significant crop damage and yield losses in most crops (Bailey-Serres and Voesenek, 2008;Bailey-Serres et al, 2012b;Bailey-Serres and Colmer, 2014;Voesenek et al, 2016). The response of plants to hypoxic stress is highly complex and involves changes in mRNA and protein levels and subsequent biochemical and physiological adaptations.…”

Noncanonical Alternative Polyadenylation Contributes to Gene Regulation in Response to Hypoxia

Stresses from various environmental challenges continually confront plants, and their responses are important for growth and survival. One molecular response to such challenges involves the alternative polyadenylation of mRNA. In plants, it is unclear how stress affects the production and fate of alternative mRNA isoforms. Using a genome-scale approach, we show that in Arabidopsis thaliana, hypoxia leads to increases in the number of mRNA isoforms with polyadenylated 39 ends that map to 59-untranslated regions (UTRs), introns, and protein-coding regions. RNAs with 39 ends within protein-coding regions and introns were less stable than mRNAs that end at 39-UTR poly(A) sites. Additionally, these RNA isoforms were underrepresented in polysomes isolated from control and hypoxic plants. By contrast, mRNA isoforms with 39 ends that lie within annotated 59-UTRs were overrepresented in polysomes and were as stable as canonical mRNA isoforms. These results indicate that the generation of noncanonical mRNA isoforms is an important feature of the abiotic stress response. The finding that several noncanonical mRNA isoforms are relatively unstable suggests that the production of non-stop and intronic mRNA isoforms may represent a form of negative regulation in plants, providing a conceptual link with mechanisms that generate these isoforms (such as alternative polyadenylation) and RNA surveillance.

“…Under flooding conditions, the reduction in oxygen availability can induce a number of physiological imbalances that strongly impact key aspects of the growth, development, and survival of flooded species (Guo, Huang, Xu, & Zhang, 2011;Li et al, 2015). The susceptibility, extent of damage, and lifespan of flooded plants vary widely among species and depend on the ability to invoke a series of morpho-anatomical (production of lenticels, adventitious roots, and aerenchyma), biochemical (increased fermentative metabolism), and physiological (increased ethylene production) adjustments (Bailey-Serres & Colmer, 2014;Herrera, 2013;Voesenek & Bailey-Serres, 2015). Common effects of exposure to flooding stress, especially for sensitive species, include inhibition of root and shoot growth, leaf necrosis, bark damage, increased ROS production, and several other metabolic disorders (Ferner, Rennenberg, & Kreuzwieser, 2012;Gupta & Igamberdiev, 2016;Kreuzwieser & Rennenberg, 2014;Liu, Cheng, Xiao, Guo, & Wang, 2014;Steffens & Rasmussen, 2016;Voesenek & Bailey-Serres, 2015).…”

Anthropogenic activities such as uncontrolled deforestation and increasing greenhouse gas emissions are responsible for triggering a series of environmental imbalances that affect the Earth's complex climate dynamics. As a consequence of these changes, several climate models forecast an intensification of extreme weather events over the upcoming decades, including heat waves and increasingly severe drought and flood episodes. The occurrence of such extreme weather will prompt profound changes in several plant communities, resulting in massive forest dieback events that can trigger a massive loss of biodiversity in several biomes worldwide. Despite the gravity of the situation, our knowledge regarding how extreme weather events can undermine the performance, survival, and distribution of forest species remains very fragmented. Therefore, the present review aimed to provide a broad and integrated perspective of the main biochemical, physiological, and morpho‐anatomical disorders that may compromise the performance and survival of forest species exposed to climate change factors, particularly drought, flooding, and global warming. In addition, we also discuss the controversial effects of high CO2 concentrations in enhancing plant growth and reducing the deleterious effects of some extreme climatic events. We conclude with a discussion about the possible effects that the factors associated with the climate change might have on species distribution and forest composition.
