Project description:We show that an abrupt waterlogging treatment of Arabidopsis thaliana plants triggers a systemic ROS and calcium wave response, and that the waterlogging-triggered ROS wave response is dependent on RBOHD, calcium-permeable channels GLR3.3 and GLR3.6, and aquaporin PIP2;1 proteins. We further show that waterlogging stress is accompanied by a rapid systemic transcriptomic response that is evident as early as 10 min following waterlogging initiation and is partially dependent on RBOHD. Interestingly, the abrupt waterlogging stress resulted in the triggering of a rapid hydraulic wave response and the transient opening of stomata on leaves. Taken together, our findings reveal that the initiation of waterlogging stress in plants is accompanied by rapid systemic transcriptomic and physiological responses that involve the ROS, calcium, and hydraulic waves. These findings reveal that systemic plant responses to waterlogging stress are rapid and at least partially dependent on cell-to-cell signaling mechanisms.

Project description:Global gene expression was compared between roots of cotton plants (variety Sicot 71) flooded for 4 hours and roots of unflooded cotton plants. Global gene expression was also compared between leaves of cotton plants (variety Sicot 71) flooded for 24 hours and leaves of unflooded cotton plants. Waterlogging stress causes yield reductions in cotton (Gossypium hirsutum L.). A major component of waterlogging stress is the lack of oxygen available to submerged tissues. While changes in expressed protein, gene transcription and metabolite levels have been studied in response to low oxygen stress, little research has been done on molecular responses to waterlogging in cotton. We assessed cotton growth responses to waterlogging and assayed global gene transcription responses in root and leaf cotton tissues of partially submerged plants. Waterlogging causes significant reductions in stem elongation, shoot mass, root mass, and leaf number. At the global gene expression level waterlogging significantly alters the expression of 1012 genes (4.2% of genes assayed) in root tissue as early as 4h after flooding. Many of these genes are associated with cell wall modification and growth pathways, glycolysis, fermentation, mitochondrial electron transport and nitrogen metabolism. Waterlogging of plant roots also altered global leaf gene expression, significantly changing the expression of 1305 genes (5.4% of genes assayed) after 24h of flooding. Genes associated with cell wall growth and modification, tetrapyrrole synthesis, hormone response, starch metabolism and nitrogen metabolism were affected in leaf tissues of waterlogged plants. Implications of these results for the development of waterlogging tolerant cotton are discussed. Keywords: Stress Response Plants of cotton cultivar Sicot 71 were grown to the two-leaf stage in tubs. For stress treatments plants were either watered as normal or flooded with water to completely submerge the root system. At four and twenty-four hours post-flooding samples of root or leaf tissue were taken from control and flooded plants. Total RNA was extracted from each tissue sample and assayed on cotton Affymetrix chips. Two biological replications were used for each comparison.

Project description:Gene expression analysis by high-throughtput RNA-sequencing from roots of waterlogged jatropha (Jatropha curcas). Six leaf stage seedlings (~30 d.o.) were subjected to 24 h of soil waterlogging. 4 samples, 2 conditions (24 h nonstress and 24 h waterlogging stress) and 2 independent biological replicates of 2 mRNA pools

Project description:Waterlogging leads to major crop losses globally, particularly for waterlogging sensitive crops such as barley. Waterlogging reduces oxygen availability and results in additional stresses, leading to the activation of hypoxia and stress response pathways that promote plant survival. Although certain barley varieties have been shown to be more tolerant to waterlogging than others and some tolerance-related QTLs have been identified, the molecular mechanisms underlying this trait are mostly unknown. Transcriptomics approaches can provide very valuable information for our understanding of waterlogging tolerance. Here, we surveyed 21 barley varieties for the differential transcriptional activation of conserved hypoxia-response genes under waterlogging, and selected five varieties with different levels of induction of core hypoxia-response genes. We further characterized their phenotypic response to waterlogging in terms of shoot and root traits. RNA-sequencing to evaluate the genome-wide transcriptional responses to waterlogging of these selected varieties led to the identification of a set of 98 waterlogging-response genes common to the different datasets. Many of these genes are orthologs of the so-called ‘core hypoxia response genes’, thus highlighting the conservation of plant responses to waterlogging. Hierarchical clustering analysis also identified groups of genes with intrinsic differential expression between varieties prior to waterlogging stress. These genes could constitute interesting candidates to study ‘predisposition’ to waterlogging tolerance or sensitivity in barley.

Project description:Potato, the most important non-cereal crop, is highly water and space efficient but susceptible to abiotic stress such as heat, drought, or flooding. Due to climate change the likelihood of such stresses to occur, individually, sequentially, or simultaneously, has dramatically increased. While we have detailed insights into plant responses to single stresses in some model plants, the understanding of acclimation to multiple abiotic stresses in crops is still very limited. Here we present a comprehensive molecular and physiological profiling of potato (Solanum tuberosum, cv. Desirée) under both single and multiple abiotic stresses (heat, drought, and waterlogging), designed to mimic realistic future scenarios. Daily phenomics analysis enabled monitoring of the acclimation responses over time. In parallel, leaf samples were taken throughout the 28-day experiment for multi-omics analysis including transcriptomics, metabolomics, proteomics, and hormonomics. At the end of the period, critical metabolites of tuber samples were analysed. To facilitate the multi-omics analyses, the dataset was integrated with expert knowledge, an approach that is increasingly necessitated in the development of high-throughput pipelines in agricultural research. Waterlogging had immediate and most dramatic effects, and surprisingly, the responses were similar to drought stress. In contrast, distinct stress signatures at morpho-physiological, metabolic, and molecular levels were found in response to heat or drought stress and to a combination of both.

Project description:Purpose: To gain a better understanding of the molecular mechanisms that enable de novo AR primordia emergence upon waterlogging, the RNA sequencing-based transcriptomic responses of two contrasting cucumber genotypes, Zaoer-N (waterlogging tolerant) and Pepino (waterlogging sensitive), which differed in their abilities to form AR were compared. Conclusion: This research broadens our understanding of the mechanism underlying waterlogging-triggered ARs emergence, and provides valuable information for the breeding of cucumber with enhanced waterlogging tolerance.
