Pectin From Fruit Peel Waste: A Sustainable Source for Production of Active Packaging Films
Composite film prepared using PVA, pectin form passion and lime peel had excellent mechanical, optical, thermal and bioactive properties. This film was used to pack strawberries and plums during chilled storage. Active film could significantly increase the shelf life of both the fruits. ABSTRACTPectin from lemon and passion fruit peels was studied for its potential to serve as a source of biopolymer for preparation of active film. To develop a packaging film appropriate for fruits, different combinations of polyvinyl alcohol (PVA), pectin from lemon and passion fruit peel and rosemary essential oil (REO) were evaluated. Ex...

Wildfire Smoke Exposure during SARS-CoV-2 Vaccination Impairs Immunity via Natural Killer Cell derived IL-13
Wildfires are increasing in intensity, duration, and frequency with smoke plums affecting the lives of millions over large geographic areas. The immune modulatory effects of wildfire smoke are unclear. We previously showed that a major wildfire smoke component, ozone, inhibited dendritic cell lymph node homing (an essential process in vaccine immunity) by suppressing NK cell-derived IFN- γ expression in mice.

Screening and characterization of biocontrol bacteria isolated from Ageratum conyzoides against Collectotrichum fructicola causing Chinese plum (Prunus salicina Lindl.) anthracnose
Chinese plum (Prunus salicina Lindl.) is a nutritionally and economically important stone fruit widely grown around the world. Anthracnose, caused by Collectotrichum spp., is one of the primary biotic stress factors limiting plum production. Medicinal plants may harbor rhizospheric or endophytic microorganisms that produce bioactive metabolites that can be used as anthracnose biocontrol agents. Here, 27 bacterial isolates from the medicinal plant A. conyzoides with diverse antagonistic activities against C. fructicola were screened. Based on morphological, physiological, biochemical, and molecular characterization, 25 of t...

Genes, Vol. 14, Pages 2035: A High-Quality Reference Genome Assembly of Prinsepia uniflora (Rosaceae)
This study introduces a meticulously constructed genome assembly at the chromosome level for the Rosaceae family species Prinsepia uniflora, a traditional Chinese medicinal herb. The final assembly encompasses 1272.71 megabases (Mb) distributed across 16 pseudochromosomes, boasting contig and super-scaffold N50 values of 2.77 and 79.32 Mb, respectively. Annotated within this genome is a substantial 875.99 Mb of repetitive sequences, with transposable elements occupying 777.28 Mb, constituting 61.07% of the entire genome.

Genes, Vol. 14, Pages 1679: Genome-Wide Identification and Expression Profiling Analysis of SWEET Family Genes Involved in Fruit Development in Plum (Prunus salicina Lindl)
an Wang
SWEETs (sugars will eventually be exported transporters) play a vital role in longer-distance sugar transportation, and thus control carbon flow and energy metabolism in plants. SWEET genes have been identified in various plant species, but their functions in fruit development remain uncharacterized. Here, we isolated 15 putative PsSWEETs from the Prunus salicina genome. For further analysis, comprehensive bioinformatics methods were applied to determine the gene structure, chromosome distribution, phylogeny, cis-acting regulatory elements, and expression profiles of PsSWEETs. qRT-PCR analysis suggested that th...

Changes of water-soluble inorganic sulfate and nitrate during severe dust storm episodes in a coastal city of North China
Environ Pollut. 2023 Aug 4;335:122288. doi: 10.1016/j.envpol.2023.122288. Online ahead of print.ABSTRACTDust storms are one of the largest sources of non-exhaust emissions in China, which can adversely affect air quality and human health during long-distance transportation. To study the influence of dust storms on aerosol particle composition, samples of fine aerosol (PM2.5) were collected before, during, and after the severe dust storm episodes in a coastal city of North China. Then the water-soluble inorganic ions in the filters were analyzed. The results showed that the chemical composition varied significantly in diffe...

Reconnoitring the antioxidant and antibacterial potential of different fruits after tannin acyl hydrolase mediated biotransformation
ABSTRACTCondensed and hydrolyzable tannins are secondary metabolites present in almost every plant part. Tannase enzyme acts on hydrolyzable tannins to produce gallic acid and tannase-mediated end-products with immense therapeutic potential. Seven different fruits with significant presence of hydrolyzable tannin content were selected to check for phenol, tannin, and hydrolyzable tannin contents.Prunus domestica had the maximum phenol content, that is, 85.4 ± 0.207, followed bySyzygium cumini,Fragaria ananassa,Rubus fruticosus, andPsidium guajava. Plum showed the maximum number of hydrolyzable tannins. Fruit extracts we...
