Abstract Carotenoid cleavage dioxygenases (CCDs) form hormones and signaling molecules. Here we show that a member of an overlooked plant CCD subfamily from rice, name Zaxinone Synthase (ZAS), can produce zaxinone, novel apocarotenoid metabolite in vitro. Loss-of-function mutants ( zas ) contain less exhibit retarded growth showed elevated levels strigolactones (SLs), hormone determines architecture, mediates mycorrhization facilitates infestation by root parasitic weeds, such as Striga spp....
In seed plants, strigolactones (SLs) regulate architecture and induce mycorrhizal symbiosis in response to environmental cues. SLs are formed by combined activity of the carotenoid cleavage dioxygenases (CCDs) 7 8 from 9-cis-β-carotene, leading carlactone that is converted cytochromes P450 (clade 711; MAX1 Arabidopsis) into various SLs. As Physcomitrella patens possesses CCD7 CCD8 homologs but lacks MAX1, we investigated if PpCCD7 together with PpCCD8 form how deletion these enzymes...
Strigolactones are key regulators of plant development and interaction with symbiotic fungi; however, quantitative tools for strigolactone signaling analysis lacking. We introduce a genetically encoded hormone biosensor used to analyze strigolactone-mediated processes, including the study components involved in perception/signaling complex structural specificity sensitivity natural synthetic strigolactones Arabidopsis, providing insights into stereoselectivity perception. Given high...
The excessive application of synthetic fertilizers can result in severe environmental risks, while composting green and fresh feedstocks provide slow-release nutrients. Therefore, the aim current investigation was to study effects eight individual combination treatments azolla compost NPK (control = no fertilizer compost; 100% full recommended dose as follows: 165 kg N ha−1, 37 P2O5 ha−1 50 K2O ha−1; 70% NPK; 40% (5 t DM ha−1); 50% + 30% 60% compost) on rice growth, productivity nutrient...
The study aims to describe phageome of soil rhizosphere M.oleifera in terms the genes encoding CAZymes and other KEGG enzymes.Genes rhizospheric virome wild plant species Moringa oleifera were investigated for their ability encode useful (Kyoto Encyclopedia Genes Genomes) enzymes resist antibiotic resistance (ARGs) soil.Abundance these was higher microbiome than bulk soil. Detected viral families include family Potyviridae as well tailed bacteriophages class Caudoviricetes that are mainly...
The metagenomic whole genome shotgun sequencing (mWGS) approach was used to detect signatures of the rhizosphere microbiomes Dipterygium glaucum and surrounding bulk soil microbiomes, differential microbial responses due watering. Preliminary results reflect reliability experiment rationality grouping microbiomes. Based on abundance non-redundant genes, bacterial genomes showed highest level, followed by Archaeal Eukaryotic genomes, then, least abundant viruses. Overall indicate that most...
Obesity is a worldwide epidemic associated with many health problems. One of the new trends in care emphasis on regular exercise and healthy diet. Zeaxanthin (Zea) carotenoid beneficial effects human health. The aim this study was to investigate whether combination Zea had therapeutic obesity induced by an HFD rats. Sixty male Wistar rats were randomly divided into five groups twelve: fed standard diet; high-fat diet (HFD); Zea; Exc; both Exc. To induce obesity, for twelve weeks. Then,...
Epidemiological studies have shown that the consumption of a high-fat diet (HFD) is positively related to development obesity. Lycopene (LYC) can potentially combat HFD-induced obesity and metabolic disorders in rats. This study aimed investigate effect LYC on syndrome assess its anti-inflammatory antioxidant effects liver adipose tissue rats fed an HFD. Thirty-six male Wistar albino were divided into three groups. Group Ι (the control group) was normal diet, group ΙΙ received HFD for 16...
The functional processes and mutual benefits of the wild plant Moringa oleifera its rhizosphere microbiome were studied via metagenomic whole-genome shotgun sequencing (mWGS) in comparison with a bulk soil microbiome. results indicated high gene abundance four KEGG categories, “Cellular Processes”, “Environmental Information Processing”, “Genetic “Metabolism”, Most enriched enzymes rhizobacteria are assigned to pathway “Amino acids metabolism”, where soil-dwelling microbes use amino as...
Due to its stimulating qualities and advantageous effects on the human body, coffee is important both consumers researchers.The roasting procedure method used prepare brew are two of most crucial factors affecting infusion's properties Caffeine (1,3,7-Trimethylpurine-2,6-dione) an alkaloid found in beans.The global demand commercial advertising have contributed increasing average consumption three cups per day.This study aims compare caffeine content antioxidant activity different types...
Aspergillus niger is a dangerous pathogen for many plants. It major cause of the destruction, rotting and decomposition plant tissues. Toxicity caused by A. can be inhibited mutation decreasing destructive effect on An 18S rDNA molecular tool was used to identify strains. Sodium azide (NaN3) chemical mutagen that disturbs fungal enzymatic activity causes microbial production cellulose-degrading enzymes, mycotoxin production. Different concentrations sodium were treat (30, 40 50 µM). The...
Moringa oleifera (or the miracle tree) is a wild plant species widely grown for its seed pods and leaves, used in traditional herbal medicine. The metagenomic whole genome shotgun sequencing (mWGS) approach was to characterize antibiotic resistance genes (ARGs) of rhizobiomes this surrounding bulk soil microbiomes figure out chance consequences highly abundant ARGs, e.g., mtrA , golS soxR oleC novA kdpE vanRO parY rbpA horizontally transfer human gut pathogens via mobile genetic elements...
Metagenomic analysis referring to CAZymes (Carbohydrate-Active enZymes) of CAZy classes encoded by the most abundant genes in rhizosphere versus bulk soil microbes wild plant Moringa oleifera was conducted. Results indicated that microbiome signatures and corresponding datasets differ between two types. class glycoside hydrolases (GH) its α-amylase family GH13 rhizobiome were proven be among families. The bacteria harboring these include phylum Actinobacteria genus Streptomyces...
The coast of the Red Sea in Jeddah City is home to a unique microbial community that has adapted extreme environmental conditions. Therefore, it essential characterize this microbiome predict how changes will affect it. aim study was conduct metagenomic sequencing 16S rRNA and ITS genes for taxonomic classification soil samples associated with halophytic plants Tamarix aphylla Halopeplis perfoliata. Fifteen were collected triplicate enhance robustness minimize sampling bias. Firstly,...
Bisphenol A (BPA) in drinking water sources is a significant concern society because BPA one of the endocrine disruption compounds (EDCs) that can cause hazards to human health even at extremely low concentration levels. This study investigated leaching potential from bottles five brands bottled Jeddah, Saudi Arabia, using high-performance liquid chromatography with diode array detector (HPLC-DAD). To best our knowledge, this first evaluate level city Jeddah. The separation was carried out...
