Summary: This study investigated the effects of exogenous sorbitol on maize seedlings under PEG-simulated drought stress. Exogenous sorbitol significantly alleviated the growth inhibition caused by PEG-simulated drought stress. The seedlings treated with PEG plus 10 mM sorbitol showed better growth than those treated with PEG, 100 mM sorbitol, and PEG plus 100 mM sorbitol. The application of exogenous sorbitol enhanced the accumulation of osmotic substances and improved antioxidant systems to improve drought tolerance.

Summary: The study found that polyethylene glycols or polyethylene glycol monomethyl ethers can induce the association of integral membrane protein with detergent particles, and the extent of association is related to the energy level of particles in aggregates. Polymers are more effective precipitants for more hydrophilic particles, with the capacity per weight for solvent molecules increasing with molecular weight. Larger PEG(MME)s have stronger precipitation effects, and the depletion force of entropic origin accelerates particle association.

Summary: In this study, a facile and effective method for enhancing the hydrophilicity and antifouling performance of polyamide nanofiltration membranes was developed by introducing a crosslinking network derived from epoxy and polyethylene glycol. The modified membranes showed decreased water contact angle, as well as lower flux decline ratio and higher flux recovery ratio, indicating excellent long-term antifouling properties.

Summary: Plasma-assisted grafting of different molecular weight PEG compounds onto the LDPE surface improved adhesion between LDPE and Al, significantly enhancing wettability. Surface modifications were confirmed through XPS and FTIR, while adhesion characteristics were analyzed using peel tests, showing a significant increase in peel resistance with PEG solution.

Summary: Climate change will increase the frequency of drought, heat waves, and wildfires. The study analysed the effects of fire recurrence and induced water stress on seed germination and root cell division in Pinus pinaster Aiton. Results showed that osmotic stress and fire recurrence did not significantly influence the germination index of the seeds. However, high PEG concentration inhibited root growth after germination, while moderate PEG concentration induced cytogenetic anomalies, particularly in areas exposed to fire. Fire recurrence seemed to reduce the water stress response, negatively impacting cell division and root growth.

Summary: The CrPIP2;3 gene plays a significant role in response to high salt-alkaline and high osmotic stress by regulating water homeostasis, rather than serving as an ROS transporter, influencing various physiological processes in plant cells.

Summary: This study reveals that the inefficiency of bioconjugation reactions, such as protein PEGylation, is caused by the excluded volume effect (EVE) between methoxy poly(ethylene glycol) (mPEG) and proteins. The researchers found that this EVE leads to the self-assembly of proteins and reactive mPEG into separate protein-rich and mPEG-rich domains. By adding unreactive low-molecular weight mPEG as a co-solvent, the association between the larger protein and reactive mPEG can be promoted, resulting in improved reaction efficiency.

Summary: The study found that drought stress has a significant impact on the growth and physiological indices of passion fruit. Drought stress induced by PEG can significantly decrease fresh weight, chlorophyll content, and root vitality, while increasing the contents of soluble protein, proline, and malondialdehyde. The activities of antioxidant enzymes showed an increasing trend and then a decreasing trend, with the highest value at the sixth day of drought stress. Among all the stress treatments, 20% PEG had the most significant effect on passion fruit seedlings.

Summary: This study systematically explored the use of polyethylene glycol (PEG) with different molecular weights and concentrations as a pore modifier in protein purification membranes, improving water flux, BSA rejection, and antifouling properties. The results showed that different types of PEG had varying effects on membrane performance and revealed the relationship between porogen and membrane property-performance.

Summary: Drought stress has a negative impact on maize growth and yield. This study aimed to identify drought-tolerant maize varieties and found that local accessions BI3, SB5, DS2, and MN3, as well as the hybrid variety H, showed tolerance to drought stress. Increasing levels of Polyethylene glycol 6000 caused a decrease in germination characteristics and growth parameters. The drought tolerance indexes indicated that H, SB5, DS2, MN3, and BI3 are drought-tolerant maize varieties.
