In this study, green synthesis of silver /silver oxide nanoparticles was successfully prepared from Phoenix Dactylifera L aqueous leaves extract. The effect of different volume ratio (% v/v) (Plant extract / Precursor) on the nanoparticles silver /silver oxide nanoparticles formation, optical properties, and catalytic activity for dye degradation was studied. The obtained Ag/Ag2O nanoparticles were characterized using various techniques, such as UV-Visible, FT-IR, XRD, SEM for this purpose. The UV-Vis spectrum shows the absorption at 430 nm associated with Ag/Ag2O NPs. The optical bandgap values were found to be in the range of 3.22 to 4.47 eV for the direct bandgap and 3.73 to 5.23 eV for the indirect bandgap. The functional groups present in plant extracts were studied by FTIR. XRD confirmed the crystalline nature of Ag / Ag2O NP, and its average particle size was between 28.66-39.40 nm. SEM showed that the green synthesized silver/silver oxide nanoparticles have a spherical shape. The purpose of this study, it highlights the high catalytic activity for dye degradation of Ag/Ag2O NPs green synthesized. As a result, the use of Phoenix Dactylifera L aqueous leaves extract offers a cost-effective and eco-friendly method.

“…The TFC of 905 accessions from the primary core collection in Yunnan province, China, was also identified [ 11 ]. In addition, the TFC of less than 20 Indian and South Korean rice varieties was identified [ 12 , 13 , 14 , 15 ]. Therefore, to identify germplasm rich in flavonoids, it is necessary to select more varieties with a wider geographical distribution and greater genetic variation.…”

Flavonoids have anti-inflammatory, antioxidative, and anticarcinogenic effects. Breeding rice varieties rich in flavonoids can prevent chronic diseases such as cancer and cardio-cerebrovascular diseases. However, most of the genes reported are known to regulate flavonoid content in leaves or seedlings. To further elucidate the genetic basis of flavonoid content in rice grains and identify germplasm rich in flavonoids in grains, a set of rice core collections containing 633 accessions from 32 countries was used to determine total flavonoid content (TFC) in brown rice. We identified ten excellent germplasms with TFC exceeding 300 mg/100 g. Using a compressed mixed linear model, a total of 53 quantitative trait loci (QTLs) were detected through a genome-wide association study (GWAS). By combining linkage disequilibrium (LD) analysis, location of significant single nucleotide polymorphisms (SNPs), gene expression, and haplotype analysis, eight candidate genes were identified from two important QTLs (qTFC1-6 and qTFC9-7), among which LOC_Os01g59440 and LOC_Os09g24260 are the most likely candidate genes. We also analyzed the geographic distribution and breeding utilization of favorable haplotypes of the two genes. Our findings provide insights into the genetic basis of TFC in brown rice and could facilitate the breeding of flavonoid-rich varieties, which may be a prevention and adjuvant treatment for cancer and cardio-cerebrovascular diseases.
