The G protein-coupled receptor COLD1 promotes chilling tolerance in maize during germination
In this study, a chilling-tolerance gene in maize, ZmCOLD1, was cloned and characterized. This gene encodes a G protein-coupled receptor that is localized to the plasma membrane and the endoplasmic reticulum. A single nucleotide polymorphism (SNP) in ZmCOLD1, SNP2738, was found to confer chilling tolerance and to have promoted maize adaptations during speciation from teosinte. Overexpression of the excellent haplotype ZmCOLD1Hap11 significantly enhanced chilling tolerance, whereas knocking down ZmCOLD1 increased sensitivity to low temperatures during the germination and seedling stages. ZmCOLD1 was associated with an influ...

Oxidized of chitosan with different molecular weights for potential antifungal and plant growth regulator applications
Int J Biol Macromol. 2023 Sep 11:126862. doi: 10.1016/j.ijbiomac.2023.126862. Online ahead of print.ABSTRACTThe application of Chitosan (CS) in drug delivery systems, plant growth promotion, antibacterial potentiality and plant defense is significantly limited by its inability to dissolve in neutral solutions. In this work, CS with different molecular weights (Mw) has been oxidized, yielding five kinds of oxidized chitosan (OCS 1-5) with solubilities in neutral solutions. The results obtained from Fourier Transform Infrared Spectroscopy clearly showed the successful oxidation of the hydroxyl group to form aldehyde and carb...

Novel cellulose derivative containing amino phenyl acetic acid as sustainable adsorbent for removal of cationic and anionic dyes
Int J Biol Macromol. 2023 Sep 2:126687. doi: 10.1016/j.ijbiomac.2023.126687. Online ahead of print.ABSTRACTThe synthesis and characterization of a novel cellulose derivative as a potential sustainable adsorbent for cationic and anionic dyes are described through processing in ionic liquids. Cellulose was solubilized in ionic liquid with tosyl chloride to form tosyl cellulose which reacted with 4-amino phenyl acetic acid through nucleophilic substitution mechanism. The new cellulose derivative was characterized and explored as an effective adsorbent for methylene blue (MB) and methyl orange (MO) removal, and the adsorption ...

Malus baccata (Linn.) Borkh polyphenols-loaded nanoparticles ameliorate intestinal health by modulating intestinal function and gut microbiota
Int J Biol Macromol. 2023 Aug 11:126233. doi: 10.1016/j.ijbiomac.2023.126233. Online ahead of print.ABSTRACTThe aim of this study was to construct the nanoparticles based on Hohenbuehelia serotina polysaccharides and mucin for encapsulation of the polyphenols from Malus baccata (Linn.) Borkh (MBP-MC-HSP NPs), and investigate their effects on intestinal function and gut microbiota in mice. The results showed that MBP-MC-HSP NPs did not have any toxic and side effect by determining organ indexes and hematological parameters. The colonic index, colonic length as well as colonic histology were significantly improved by treatme...

Effects of deacetylation degree of chitosan on the structure of aerogels
Int J Biol Macromol. 2023 Aug 3:126123. doi: 10.1016/j.ijbiomac.2023.126123. Online ahead of print.ABSTRACTChitosan aerogels, obtained by (supercritical) CO2 drying of hydrogels, are novel adsorbents because of their large surface area and high porosity. Intrinsic properties of chitosan such as molecular weight (MW) and degree of deacetylation (DDA) had large impacts on the characteristics of chitosan aerogels. Although there are a few studies about the effects of solely DDA or MW on aerogel structure, none of them has focused on the mutual effects. The study aims to investigate the combined effects of MW and DDA of chitos...

Human RNase 1 can extensively oligomerize through 3D domain swapping thanks to the crucial contribution of its C-terminus
Int J Biol Macromol. 2023 Aug 1:126110. doi: 10.1016/j.ijbiomac.2023.126110. Online ahead of print.ABSTRACTHuman ribonuclease (RNase) 1 and bovine RNase A are the proto-types of the secretory "pancreatic-type" (pt)-RNase super-family. RNase A can oligomerize through the 3D domain swapping (DS) mechanism upon acetic acid (HAc) lyophilisation, producing enzymatically active oligomeric conformers by swapping both N- and C-termini. Also some RNase 1 mutants were found to self-associate through 3D-DS, however forming only N-swapped dimers. Notably, enzymatically active dimers and larger oligomers of wt-RNase 1 were collected he...

Preparation and characterization of poly(3-hydroxybutyrate)/chitosan composite films using acetic acid as a solvent
Int J Biol Macromol. 2023 Jul 24:125970. doi: 10.1016/j.ijbiomac.2023.125970. Online ahead of print.ABSTRACTPoly(3-hydroxybutyrate) and chitosan are among the most widely used polymers for biomedical applications due to their biocompatibility, renewability and low toxicity. The creation of composite materials based on biopolymers belonging to different classes makes it possible to overcome the disadvantages of each of the components and to obtain a material with specific properties. Solving this problem is associated with difficulties in the selection of conditions and solvents for obtaining the composite material. In our ...

Auxin-responsive protein MaIAA17-like modulates fruit ripening and ripening disorders induced by cold stress in 'Fenjiao' banana
Int J Biol Macromol. 2023 Jul 13;247:125750. doi: 10.1016/j.ijbiomac.2023.125750. Online ahead of print.ABSTRACTCold stress severely affects the banana fruit softening and de-greening, significantly inhibiting the ripening processes. However, the mechanism of ripening disorder caused by chilling injury (CI) in banana fruit remains largely unknown. Herein, MaIAA17-like, an Auxin/Indole-3-Acetic Acid (Aux/IAA) family member, was found to be highly related to the softening and de-greening in 'Fenjiao' banana. Its expression was rapidly increased with fruit ripening and then gradually decreased under normal ripening conditions...

Int J Biol Macromol. 2023 Jul 12:125786. doi: 10.1016/j.ijbiomac.2023.125786. Online ahead of print.ABSTRACTThis work aimed to establish a novel membrane consisting of hemostatic polysaccharides, kappa-carrageenan (KC), and carboxymethyl chitosan (CMC) in tandem with polyvinyl alcohol that spun together as a matrix and loaded with tranexamic acid (TXA) as antifibrinolytic agent for further coagulation effect during and after oral surgeries. The electrospinning of KC was done for the first time and in comparison of CMC has better hemostatic efficacy. The effect of the hemostat was investigated by its surface morphology (SEM...

Int J Biol Macromol. 2023 Jun 29:125628. doi: 10.1016/j.ijbiomac.2023.125628. Online ahead of print.ABSTRACTA strain of Bacillus that can tolerate 10 g/L acetic acid and use the volatile fatty acids produced by the hydrolysis and acidification of activated sludge to produce polyhydroxyalkanoate was screened from the activated sludge of propylene oxide saponification wastewater. The strain was identified by 16S rRNA sequencing and phylogenetic tree analysis and was named Bacillus cereus L17. Various characterization methods showed that the polymer synthesized by strain L17 is poly-β-hydroxybutyric acid, which has low cryst...
