“…The sucrose synthase ( SuSy ) gene encodes an enzyme that participates in low oxygen level tolerance [ 75 , 76 ]. The role of Susy is the hydrolysis of sucrose to fructose and UDP-glucose in order to drive ATP production by glycolysis, which is important in oxygen deprivation tolerance [ 77 ].…”

Waterlogging (WL), excess water in the soil, is a phenomenon often occurring during plant cultivation causing low oxygen levels (hypoxia) in the soil. The aim of this study was to identify candidate genes involved in long-term waterlogging tolerance in cucumber using RNA sequencing. Here, we also determined how waterlogging pre-treatment (priming) influenced long-term memory in WL tolerant (WL-T) and WL sensitive (WL-S) i.e., DH2 and DH4 accessions, respectively. This work uncovered various differentially expressed genes (DEGs) activated in the long-term recovery in both accessions. De novo assembly generated 36,712 transcripts with an average length of 2236 bp. The results revealed that long-term waterlogging had divergent impacts on gene expression in WL-T DH2 and WL-S DH4 cucumber accessions: after 7 days of waterlogging, more DEGs in comparison to control conditions were identified in WL-S DH4 (8927) than in WL-T DH2 (5957). Additionally, 11,619 and 5007 DEGs were identified after a second waterlogging treatment in the WL-S and WL-T accessions, respectively. We identified genes associated with WL in cucumber that were especially related to enhanced glycolysis, adventitious roots development, and amino acid metabolism. qRT-PCR assay for hypoxia marker genes i.e., alcohol dehydrogenase (adh), 1-aminocyclopropane-1-carboxylate oxidase (aco) and long chain acyl-CoA synthetase 6 (lacs6) confirmed differences in response to waterlogging stress between sensitive and tolerant cucumbers and effectiveness of priming to enhance stress tolerance.

“…Flavonoids are reported to have plant protective properties through strong antioxidant activity (Agati et al ., ), and elevated concentrations of flavonoids have been described in AM roots (Schliemann et al ., ; Mechri et al ., ; Mollavali et al ., ). A potential contribution of CAT to plant protection against abiotic stress is also supported by reports of the increased salinity or flooding tolerance achieved after exogenous application of CAT to sweet pepper and tomato plants (Yiu et al ., , ).…”

Arbuscular mycorrhizal (AM) symbioses can improve plant tolerance to multiple stresses. We compared three AM fungi (AMF) from different genera, one of them isolated from a dry and saline environment, in terms of their ability to increase tomato tolerance to moderate or severe drought or salt stress. Plant physiological parameters and metabolic profiles were compared in order to find the molecular mechanisms underlying plant protection against stress. Mycorrhizal growth response was determined, and ultrahigh-performance LC-MS was used to compare the metabolic profile of plants under the different treatments. All AMF increased plant tolerance to stress, and the positive effects of the symbiosis were correlated with the severity of the stress. The AMF isolated from the stressful environment was the most effective in improving plant tolerance to salt stress. Differentially accumulated compounds were identified and the antistress properties of some of them were confirmed. We demonstrate that AM symbioses increase plant metabolic plasticity to cope with stress. Some responses were common to all AMF tested, while others were specifically related to particular isolates. Important metabolism reprograming was evidenced upon salt stress, and we identified metabolic pathways and compounds differentially accumulated in mycorrhizas that may underlie their enhanced tolerance to stress.

“…Despite the apparent water availability under ooded conditions, a reduction in leaf RWC was reported in the previous studies, e.g., for sesame (Anee et al 2019), mung beans (Kumar et al 2013) and tomato (Yiu et al 2011). Under ooding stress, ooding-sensitive species become wilted due to the decrease in root hydraulic conductivity and consequently reduction of root water uptake (Kramer and Jackson 1954).…”

Background and aims There is little information about the effect of grass-fungal endophyte symbiota on plant performance under oxygen-limited conditions. This study aimed to investigate the effect of Epichloë endophyte symbiosis and tall fescue genotype on plant responses to oxygen stress in a greenhouse pot experiment.Methods A greenhouse pot experiment was conducted with seven air-filled porosity levels in a sandy loam soil using two genotypes (75C and 75B) of tall fescue (Festuca arundinacea = Schedonorus arundinaceus Schreb.) infected with and without endophytic fungus Epichlöe coenophiala (E+ and E–, respectively). Some selected growth and physiological parameters were determined after nine-month application of the treatments.Results The results showed that E+ plants benefited from endophytic symbiosis and showed slightly higher root and shoot development, more leaf chlorophyll, and lower catalase and ascorbate peroxidase activity than E– plants under poor aeration. The E– plants also coped with poor aeration conditions by forming adventitious roots at the soil surface, aerenchyma formation within the root tissue, and increased alcohol dehydrogenase (ADH) activity.Conclusions The presence of endophyte improved the performance of the genotype E+ 75B under anaerobic conditions, while endophyte had an adverse effect on the performance of the genotype E+ 75C. In general, Epichloë endophyte presence decreased the flooding induced oxidative stress and prevented the formation and over-accumulation of reactive oxygen species in plant cells.
