14-3-3 proteins regulate the HCHO stress response by interacting with AtMDH1 and AtGS1 in tobacco and Arabidopsis.

Formaldehyde (HCHO) is one of the most essential common carcinogenic environmental pollutants. While 14-3-3 proteins are known to regulate the response of plants to HCHO stress, the regulatory mechanisms responsible for a tolerant phenotype remain unclear. We first performed qPCR analysis of HCHO-treated Arabidopsis and tobacco and determined that the expression of At14-3-3PSI and Nt14-3-3C genes was rapidly upregulated after HCHO stress.

Methods: This was a single-center retrospective study of 449 patients with thoracic esophageal carcinoma who underwent esophagectomy and perioperative ERAS between January 2013 and April 2021.

Overexpression of tomato glutathione reductase (SlGR) in transgenic tobacco enhances salt tolerance involving the S-nitrosylation of GR.

S-nitrosylation, a post-translational modification (PTM) dependent on nitric oxide, is essential for plant development and environmental responsiveness. However, the function of S-nitrosylation of glutathione reductase (GR) in tomato (SlGR) under NaCl stress is yet uncertain. In this study, sodium nitroprusside (SNP), an exogenous NO donor, alleviated the growth inhibition of tomato under NaCl treatment, particularly at 100 μM.

Hydrogen sulfide alleviates oxidative damage under excess nitrate stress through MAPK/NO signaling in cucumber.

Hydrogen sulfide (HS) is emerging as a potential messenger molecule involved in modulation of physiological processes in plants. Mitogen-activated protein kinase (MAPK) and nitric oxide (NO) are essential for abiotic stress signaling. This work investigated the effects of HS and the crosstalk between HS, MAPK and NO in cucumber roots under nitrate stress.

A small proportion of litter-derived nitrogen is assimilated by plant biomass or immobilized in sediments regardless of harvest management as detected by N-labeled Phragmites litter in a constructed wetland.

Emergent aquatic macrophytes play an important role in the removal of nutrients in constructed wetlands (CWs). However, plant biomass supplies litter after the onset of senescence. Although litter-derived nitrogen (N) has been considered a nutrient source for the internal loading that may reduce CW performance, little is known about the quantitative N dynamics associated with litter decomposition.

Physiological response and transcription profiling analysis reveals the role of HS in alleviating excess nitrate stress tolerance in tomato roots.

Soil secondary salinization caused by excess nitrate addition is one of the major obstacles in greenhouse vegetable production. Excess nitrate inhibited the growth of tomato plants, while application of 100 μM HS donor NaHS efficiently increased the plant height, fresh and dry weight of shoot and root, root length, endogenous HS contents and L-cysteine desulfhydrases activities. NaHS altered the oxidative status of nitrate-stressed plants as inferred by changes in reactive oxygen species (ROS) accumulation and lipid peroxidation accompanied by regulation of the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX).
