“…This effect is reversible for mild hyperosmotic pressure and cells can return to regular cell cycle dynamics, proliferation and migration upon release of the osmotic pressure. This is in agreement with similar phenomena observed previously with bacteria 9 , yeast cells 29 and plant seeds 7 , 8 , but has been barely explored in the context of human cells. Our findings highlight the importance of the local biophysical microenvironment, particularly in human cell niches likely to harbor non-cycling quiescent cells such as lymphatic and blood capillaries in the bone marrow.…”

Biophysical cues such as osmotic pressure modulate proliferation and growth arrest of bacteria, yeast cells and seeds. In tissues, osmotic regulation takes place through blood and lymphatic capillaries and, at a single cell level, water and osmoregulation play a critical role. However, the effect of osmotic pressure on single cell cycle dynamics remains poorly understood. Here, we investigate the effect of osmotic pressure on single cell cycle dynamics, nuclear growth, proliferation, migration and protein expression, by quantitative time-lapse imaging of single cells genetically modified with fluorescent ubiquitination-based cell cycle indicator 2 (FUCCI2). Single cell data reveals that under hyperosmotic stress, distinct cell subpopulations emerge with impaired nuclear growth, delayed or growth arrested cell cycle and reduced migration. This state is reversible for mild hyperosmotic stress, where cells return to regular cell cycle dynamics, proliferation and migration. Thus, osmotic pressure can modulate the reversible growth arrest and reactivation of human metastatic cells.

“…Osmotic pressure is another example of a biophysical cue that modulates cell function. Osmotic pressure changes have been widely associated with growth arrest and proliferation in plants and seeds 7 , 8 , and more recently in bacteria 9 and yeast 10 . In human physiology, osmotic regulation is present in multiple phenomena.…”

“…The salinity and mixed saline-alkaline stresses also reduced seed germination (Debez et al, 2004;Shi & Sheng, 2005). In contrast, the highest levels of salinity and mixed saline-alkaline stresses also reduced seed viability (Murillo-Amador et al, 2002;Vicente et al, 2020). The results of our study showed that seed vigor was less affected by salinity and mixed saline-alkaline stresses than by drought stress (Table 2).…”

“…Limited research has been performed on the effects of drought and salinity stress on the physiological and biochemical characteristics and performance of E. elongata (Lauriault et al, 2005;Martyniak et al, 2017;Meng & Mao, 2013). In addition, the seed germination behavior of plants is the first crucial step for the introduction of a new crop because seed germination is the initial stage in the life cycle of plants and the most sensitive stage to abiotic stress (Patade et al, 2011;Vicente et al, 2020). Based on our previous observations, we assessed seed germination effects of ten E. elongata accessions under drought, salinity and mixed saline-alkaline stresses, and the results showed that EE024 and EE030 were stronger resistance than other eight E. elongata accessions.…”

Elytrigia elongata, a rhizomatous and sparse-type perennial herb of the Triticeae tribe, with stronger drought and salt tolerance, is an important wild genetic resource for wheat variety improvement. However, no precise information about seed germination and biochemical responses of this species to drought, salinity and mixed saline-alkaline stresses is available. Hence, this experiment was conducted to investigate the effects of three abiotic stresses on seed germination and physiological characteristics of two E. elongata accessions. The results showed that drought and mixed saline-alkaline stresses impair seed germination and bud seedling growth of E. elongata. However, seed germination and bud seedling growth were promoted by 50 mmol/L, but inhibited by 100-200 mmol/L salinity treatments. The malondialdehyde (MDA) content was increased and the activities of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) in the bud seedlings were significantly increased (p <.05) with increasing osmotic stress from 0 to −0.4 MPa, and salinity and mixed saline-alkaline from 0 to 150 mmol/L, but reduced at −0.75 MPa osmotic stress and 200 mmol/L salinity and mixed saline-alkaline stresses. Under the same salinity and mixed saline-alkaline treatment, the activities of SOD and CAT of EE030 were higher than those of EE024 except in 200 mmol/L salinity treatment; however, the MDA content of EE030 was lower than that of EE024, except in 150 mmol/L salinity treatment. In conclusion, the results of this study demonstrated that E. elongata seeds are more tolerant to salinity stress than to drought and mixed saline-alkaline stresses, and EE030 seed are more tolerant to three abiotic stresses than are the seeds of EE024.

“…Seed germination is dependent upon a multitude of endogenous and exogenous factors such as temperature. The temperature is the main factor that regulates the germination process of seed (Vicente et al., 2020). There are three cardinal temperatures that germination response to temperature: base, optimal, and ceiling temperature.…”

Sprouts with higher levels of nutrients and lower content of antinutritional substances have been gained a growing interest in the influence on the human's health. The study of the influence of germination temperature and time on the metabolite profiles of sunflower seed was studied by a metabolomics approach based on gas chromatography–flame ionization detection (GC‐FID). Samples were extracted and fractionated covering a wide range of lipophilic and hydrophilic spectra. A total of 90 metabolites were identified by comparison with reference standards. Principal component analysis (PCA) revealed distinct dynamic changes in metabolites with the germinating time. Heatmap and agglomerative hierarchical clustering analysis revealed the differences and similarities among the samples. The germinating sunflower seeds clustered into three major groups. For instance, group I with a high content of sterols, monosaccharide, and amino acids, indicating the germination process, resulted in an increase in amino acids and monosaccharide. Group II had a high content of FAME and FFA. Relative targeted quantification of metabolites visually depicted by heatmap showed decreases in fatty acid methyl ester (FAME) and free fatty acid (FFA), and increases in amino acids, α‐tocopherol, sterols, and γ‐aminobutyric acid (GABA) during germination. Sunflower seeds germinated at 25°C were better for the accumulation of α‐tocopherol, stigmasterol, leucine, proline, methionine, glutamine, and GABA compared with those at 35°C. These results help to better understand how germination conditions change the nutritional quality of germinated sunflower seeds from a metabolite profile view, allowing for the rational screening and usage of germinated sunflower seeds in the food industry.
