PdbNAC1 transcription factor confers salt tolerance by regulating stress-response and secondary wall biosynthesis genes in Populus davidiana × P. bolleana.

Soil salinity represents a major abiotic stress factor that inhibits plant growth and causes substantial yield losses. NAC transcription factors (TFs) play essential roles in plant biological processes and stress responses; however, their functions and underlying mechanisms in salt stress response remain inadequately understood. In this study, we characterized a PdbNAC1 TF from P.

Cadmium (Cd) is a highly toxic non-essential heavy metal that presents substantial risks to plant life. The primary regulators and molecular mechanisms governing Cd tolerance remain incompletely understood. In this study, RNA-seq analysis was performed on Populus davidiana × P.

Constructing Self-Renewing Silicone-Hydrogel Hybrid Coatings with Integrated Fouling Resistant/Release/Killing Mode toward Superior Biofouling Defense.

Silicone hydrogel coatings, which integrate fouling self-release and fouling resistant properties, represent a groundbreaking advancement in environmentally friendly biofouling mitigation, but are still plagued by static fouling conditions and longevity concerns. In this work, Schiff base chemistry and a sol-gel technique is leverage to develop degradable silicone-hydrogel hybrid antifouling coatings by incorporating amphiphilic silicone-based polymers with terephthalaldehyde (TPE) and cinnamaldehyde (CAL). The synergistic combination of flexible Si─O bonds in the polymer backbone and reversible covalent crosslinking imparts exceptional flexibility (hardness of 0.

COF nanotubes/2D nanosheets heterojunction for superior photocatalytic bactericidal activity even at low concentration and weak light.

Microbial fouling is a huge nuisance to equipment operation and human health. Two-dimensional (2D) photocatalytic materials such as g-CN, WSe, and TiCT, show immense potential for solar-driven eradication of microbial fouling. However, limited photon absorption and rapid photogenerated electron-hole recombination curtail their photocatalytic efficiency and availability, resulting in the necessity to operate at high concentration and strong light.

An R2R3-MYB transcription factor PdbMYB6 enhances drought tolerance by mediating reactive oxygen species scavenging, osmotic balance, and stomatal opening.

Drought is a major environmental challenge that hinders the growth and development of plants. R2R3-MYB transcription factors (TFs) play a vital role in mediating responses to abiotic stress; however, their specific functions in Populus davidiana × Populus bolleana hybrid poplar plants remain underexplored. This study focused on PdbMYB6, a novel R2R3-MYB TF identified in P.

Designing a photocatalytic and self-renewed g-CN nanosheet/poly-Schiff base composite coating towards long-term biofouling resistance.

Inhibiting the adhesion and growth of marine microorganisms through photocatalysis is a potentially efficient and environmentally friendly antifouling strategy. However, the undesired "shading effect" caused by resin coatings and microbial deposition reduces the utilization of the catalysts and leads to a failure in the antifouling active substance on the coating surface. Here, we successfully developed a composite coating (DPC-) combining g-CN nanosheet (g-C-NS) photocatalysts with degradable green poly-Schiff base resins, which integrates the dual functions of enhanced dynamic self-renewal and photocatalytic antibacterial activities towards long-term anti-biofouling.

Multi-stimulus Response Behavior of Biomimetic Autocrine Waxy Materials for Potential Self-Constructing Surface Microstructures.

Many functions of terrestrial plant leaves rely on the regenerable epidermal wax layer. Biomimetic autocrine waxy materials (AWMs) inspired by renewable epidermal waxes are attracting increasing attention. However, the growth properties of the wax layer remain unclear, limiting the development of this promising material.

Cinnamaldehyde grafted porous Aerogel-Organ gel liquid infused surface for achieving difunctional long-term dynamic antifouling.

Marine biofouling caused a number of questions about energy consumption and safety. While there were still some challenges in developing an environmentally friendly, non-toxic and long-term antifouling slippery liquid-infused porous surface (SLIPS). Here, we proposed a difunctional antifouling strategy via constructing porous polydimethylsiloxane (PDMS) surface with a layer of aerogel by sol-gel method and grafted cinnamaldehyde chemically.

Antibacterial-renew dual-function anti-biofouling strategy: Self-assembled Schiff-base metal complex coatings built from natural products.

Marine biological fouling has caused huge economic losses and environmental problems. Therefore, it was essential to develop effectively environment-friendly biofouling resistance technology. Here, inspired by the natural module of bacterial secretions, animal and plant extracts, we synthesized Schiff based compounds through Tobramycin (TOB) from Streptomyces and Protocatechualdehyde (PR) from black fern.

Designing a MOF-based slippery lubricant-infused porous surface with dual functional anti-fouling strategy.

Material that resists biofouling adhesion is needed in a complex marine environment, but few of them can combine ultra-low fouling and environmental friendliness. Slippery lubricant-infused porous surface (SLIPS) is such a material, but it lacks the contact-killing ability, which limits its stability and anti-fouling efficiency. Here, we report a metal organic framework (MOF-based) Slippery ionic liquid-infused surface with excellent antifouling performance via synergistic release and contact-killing defense strategy.

Fully Repairable Slippery Organogel Surfaces with Reconfigurable Paraffin-Based Framework for Universal Antiadhesion.

Constructing a slippery lubricant-infused surface (SLIS) whose internal microstructure and surface properties can be fully repaired helps to improve its property stability and extend technological implications but has presented a huge challenge. A class of fully repairable slippery organogel surfaces (SOSs), which uses microstructured paraffin as reconfigurable supporting structure and silicone oil as lubricant dispersion medium, is reported here. Attributed to nearly 90 wt % of silicone oil stored in the slippery organogel system and good compatibility with the paraffin-based framework, SOSs combine continuous lubricity and reliable lubricant storage stability.

Self-Adjusting Lubricant-Infused Porous Hydrophobic Sticky Surfaces: Programmable Time Delay Switch for Smart Control of the Drop's Slide.

Although strategies for smart control of droplets by utilizing slippery surfaces that are typically made by infusing lubricants into porous surfaces are booming, no surface can smartly control the start or stop of droplet sliding without external environmental stimuli. A strategy for how surfaces alone, if constituted by lubricant-infused porous hydrophobic sticky surfaces (LIPHSS) with a specific interface self-adjusting system, can achieve the target of smart control of a drop's slide is presented here. The continuous self-adjustment of the interface formed by droplets and LIPHSS leads to the occurrence of droplet sinking behavior.
