Abstract:
... Aquaporins (AQPs) are one of the most ancient superfamily proteins, which are essential for maintaining the fluid homeostasis of most organisms against various environments. Here, the latest findings for function of AQPs in cell signal transduction in plants are summarized. We also put forward several issues that still need to be addressed in the future. ...

Abstract:
... The application of nanoparticles (NPs) has been shown to be a very effective technology for increasing plant yield. Their use in agriculture has been associated with the reduction of fertilization, but their effectiveness depends on the concentrations applied, physiochemical properties, and plant species. Nevertheless, one of the most common reported effects, independently on the type of NPs, is t ...
aquaporins, etc ; cysteine; hydrogen; mercury; molecular dynamics; permeability; research; Show all 7 Subjects
Abstract:
... Aquaporins (AQPs) transport water molecules across cell membranes. Although most aquaporins are inhibited by mercury ions, AQP6 was reported to be activated by binding mercury ions to residues C155 and C190. Different from C190 and the other pore-line cysteine residues, C155 is located outside the pore, thus not directly affecting the internal pathway by mercury binding to it. The molecular mechan ...

Abstract:
... Plant PIP aquaporins play a central role in controlling plant water status. The current structural model for PIP pH‐gating states that the main pH sensor is located in loopD and that all the mobile cytosolic elements participate in a complex interaction network that ensures the closed structure. However, the precise participation of the last part of the C‐terminal domain (CT) in PIP pH gating rema ...

Abstract:
... Water channels are one of the key pillars driving the development of next-generation desalination and water treatment membranes. Over the past two decades, the rise of nanotechnology has brought together an abundance of multifunctional nanochannels that are poised to reinvent separation membranes with performances exceeding those of state-of-the-art polymeric membranes within the water–energy nexu ...

Abstract:
... Melon cracking is a physiopathy that is associated with both internal and external changes by the alteration of the water balance and nutrient homeostasis in the fruit. Aquaporins are channels for water and other small solutes, and they are potentially involved in the regulation of melon cracking. In this work, we studied the mineral concentration and expression of all aquaporins in non-cracked an ...

Abstract:
... Three aquaporin water channel proteins, AQP3, AQP4 and AQP15 were localized to cells within the kidney of the spiny dogfish, Squalus acanthias, using an immunohistochemical approach. Dogfish kidney has two zones, the bundle zone (including five nephron segment bundles) and the sinus zone (with two major loops). In order to discriminate between the two loops, the cilia occurring in the first proxim ...

Abstract:
... Aquaporin incorporated nanofiltration membranes have high potential for future applications on separation processes. In this study, performance of biomimetic thin-film composite membranes containing Halomonas elongata and Escherichia coli aquaporins with different affinity tags for the removal of micropollutants was investigated.% rejection of the membranes for atrazine, terbutryn, triclosan, and ...

Abstract:
... Membrane-based separation technologies have been emerging in wastewater treatment, especially desalination, in the past few decades at the cost of higher energy consumption despite having energy recovery methods embedded with the separation technology. So, membranes used in these separation technologies are modified to provide high rejection, high water permeability flux at the expense of lower en ...
aquaporins, etc ; Escherichia coli; ambient temperature; biomimetics; desalination; lipids; mutants; permeability; polyamides; polymerization; solutes; Show all 11 Subjects
Abstract:
... Aquaporins are water channel proteins with high permeability and solute rejection, making them ideal components for the preparation of desalination biomimetic membranes. In one strategy, E. coli aquaporin Z (AqpZ) proteoliposomes are immobilized in a polyamide layer formed by interfacial polymerization at the inner surface of hollow fibers. However, once polymerization occurs, the system is almost ...

Abstract:
... Crab-eating frogs (Fejervarya cancrivora) can live in brackish water with a salinity of up to 18‰, although most amphibians are not able to tolerate such high saline environments. To investigate its potential osmoregulation, we conducted experiments in F. cancrivora and F. multistriata. The results showed that F. cancrivora made use of ions (such as Na⁺ and Cl⁻) to increase intracellular concentra ...

Abstract:
... Drought is a major challenge for agricultural production since it causes substantial yield reduction and economic loss. Autophagy is a subcellular degradation and recycling pathway that functions in plant development and responses to many stresses, including drought. In this review, we summarize the current understanding of the function of autophagy and how autophagy is upregulated during drought ...

Abstract:
... Cryopreservation is globally used as a method for long-term preservation, although freeze-thawing procedures may strongly impair the gamete function. The correct cryopreservation procedure is characterized by the balance between freezing rate and cryoprotective agents (CPAs), which minimizes cellular dehydration and intracellular ice formation. For this purpose, osmoregulation is a central process ...
... The water channel feature of the aquaporin (AQP) is considered to be the key in improving the permselectivity of AQP-based thin-film composite (TFC) polyamide (PA) membranes, yet much less attention has been paid to the physicochemical property changes of the PA layer induced by AQP-reconstituted proteoliposomes. This study systematically investigated the roles of proteoliposome constituents (lipo ...
... Plant aquaporins facilitate the transport of water across the inner membranes and play an important role in the response to water loss stress. A citrus NOD26-like intrinsic protein, CsNIP5;1, has been investigated to participate in the regulation of water permeability. In the present study, the expression profile indicated that CsNIP5;1 showed high transcription abundance in conducting tissues. Fu ...

Abstract:
... Outstanding water/ion selectivity of aquaporins paves the way for bioinspired desalination membranes. Since the amino acid asparagine (Asn) plays a critical role in the fast water conduction of aquaporins through hydrogen bonding interactions, we adapted this feature by functionalizing carbon nanotubes (CNTs) with Asn. We also studied a nonpolar amino acid and carboxylate functional groups for com ...

Abstract:
... Reports on importance of aquaporins for plant salt-resistance are rather contradictory. We have studied the consequences of expression of barley (Hordeum vulgare L.) aquaporin gene, HvPIP2;1, in transgenic tobacco plants on their water relations and capacity to grow under salinity. Detection of HvPIP2;1 protein and mRNA by immunolocalization and in situ hybridization, respectively, confirmed that ...
... Intertidal crustaceans like Carcinus maenas shift between an osmoconforming and osmoregulating state when inhabiting full-strength seawater and dilute environments, respectively. While the bodily fluids and environment of marine osmoconformers are approximately isosmotic, osmoregulating crabs inhabiting dilute environments maintain their bodily fluid osmolality above that of their environment by a ...
... MAIN CONCLUSION: A critical investigation into arsenic uptake and transportation, its phytotoxic effects, and defense strategies including complex signaling cascades and regulatory networks in plants. The metalloid arsenic (As) is a leading pollutant of soil and water. It easily finds its way into the food chain through plants, more precisely crops, a common diet source for humans resulting in ser ...

Abstract:
... The early wilting and yellowing of leaves in response to ethylene is the main limitation affecting the vase quality of cut chrysanthemums. Therefore, leaf senescence is the most difficult problem in the post-harvest and production of chrysanthemums. Nevertheless, the molecular mechanism of ethylene on the regulation of post-harvest senescence of cut chrysanthemum leaves is still unclear. In this s ...
