In the current research, unique Nano-Embedded Fungus (NEF), made by the synergic association of silver nanoparticles (AgNPs) and endophytic fungus (Piriformospora indica), is studied, and the impact of NEF on black rice secondary metabolites is reported. AgNPs were synthesized by chemical reduction process using the temperature-dependent method and characterized for morphological and structural features through UV visible absorption spectroscopy, zeta potential, XRD, SEM-EDX, and FTIR spectroscopy. The NEF, prepared by optimizing the AgNPs concentration (300 ppm) in agar and broth media, showed better fungal biomass, colony diameter, spore count, and spore size than the control P. indica. Treatment with AgNPs, P. indica, and NEF resulted in growth enhancement in black rice. NEF and AgNPs stimulated the production of secondary metabolites in its leaves. The concentrations of chlorophyll, carotenoids, flavonoids, and terpenoids were increased in plants inoculated with P. indica and AgNPs. The findings of the study highlight the synergistic effect of AgNPs and the fungal symbionts in augmenting the secondary metabolites in leaves of black rice.

Rice is the most popular food variety globally and is consumed as a staple food due to its high nutritional value. It is primarily black rice because of its rich anthocyanin levels, carbs, lipids, proteins, dietary fibres and minerals. Consumers are increasingly more aware of consuming healthy foods to maintain good health. Because of the strong demand from consumers, cultivars are now more interested in developing black rice due to its high anthocyanin content. The rice appears black because of the presence of anthocyanin in rice bran. Lysine, tryptophan and other essential amino acids are found in black rice. It also contains many antioxidants, the first line that protects against free radical damage and helps maintain good health. This rice type offers several health advantages and may reduce the risk of several ailments, including chronic ones. There are several health benefits associated with eating black rice. Atherosclerosis is lessened, the digestive system is strengthened, high blood pressure is stabilized, allergies are lessened, the body is cleansed, diabetes is better controlled, weight loss is more manageable and cancer development is slowed. It is now used in different food industries as a substitute for wheat due to its high nutritional profile, increasing protein digestion and decreasing starch digestion. This variety is also gluten-free and gluten-sensitive consumers can consume it. Black rice's history, chemical makeup and nutritional and functional qualities are all examined in this study. Black rice scientifically verified therapeutic benefits are the focus of this study paper.

“…ZnO-NPs are the most prominent NPs widely used in plant science research, and ZnO-NPs are also utilised to reduce the effects of salt stress and boost the rate of seed germination. (Mahajan et al, 2019;Mishra, 2020;Ragab et al, 2022). Our study aims to investigate the response of a landrace and salt-tolerance rice genotype Kargi and CSR 30 under different concentrations of NaCl levels and ZnO-NPs during the germination and seedling phase.…”

Salinity stress had a direct impact on rice (Oryza sativa L.) growth and physiological features throughout the early stages of development. The current study aimed to investigate the influence of Zinc oxide nanoparticles (ZnO-NPs) in the rice germination stage during salinity stress because the germination and seedling stage is critical for the correct development and growth of plants. The different concentrations of NaCl and ZnO NPs (T1 -60 mM NaCl, T2 -80 mM NaCl, T3 -100 mM NaCl, T4 -60 mM NaCl+50 ppm ZnO NPs, T5 -80 mM NaCl+50 ppm ZnO NPs and T6 -100 mM NaCl+50 ppm ZnO NPs) improve the germination rate in rice during salinity stress. We conducted our experiment in a landrace of rice Kargi and salinity tolerance rice variety CSR 30. The current study’s findings reveal that ZnO NPs have a significant effect in reducing salt stress during rice germination.
