“…Bambara groundnut (Vigna subterranea) (Mayes et al, 2019;Tan et al, 2020), winged bean (Psophocarpus tetragonolobus) (Adegboyega et al, 2019;Tanzi et al, 2019) and amaranth (Amaranthus spp.) (Sarker et al, 2020;Jamalluddin et al, 2021) have high fiber content and nutrients, such as protein, carbohydrates, unsaturated fatty acids, and essential minerals. They are thus good candidates to supplement food systems to overcome malnourishment in adults and children (Talabi et al, 2022).…”

“…Breeding programs have been developed to produce improved varieties of NUS crop species by initially characterizing germplasm. The African Orphan Crops Consortium (AOCC), in global partnership with biotechnology industries and research institutions, has initiated plans to assemble the genome sequence of 101 traditional African food crops for genetic improvement (Jamnadass et al, 2020;African Orphan Crops Consortium, 2022). To date, the genomes of at least 29 orphan crops in nine families have been sequenced, including Fonio (Digitaria exilis) (Abrouk et al, 2020), African eggplant (Solanum aethiopicum), breadfruit (Artocarpus altilis), apple-ring acacia (Faidherbia albida), Bambara groundnut (Vigna subterranea), jackfruit (Artocarpus heterophyllus), lablab (Lablab purpureus), marula (Sclerocarya birrea) and moringa (Moringa oleifera) (Chapman et al, 2022).…”

The recent Russia–Ukraine conflict has raised significant concerns about global food security, leaving many countries with restricted access to imported staple food crops, particularly wheat and sunflower oil, sending food prices soaring with other adverse consequences in the food supply chain. This detrimental effect is particularly prominent for low-income countries relying on grain imports, with record-high food prices and inflation affecting their livelihoods. This review discusses the role of Russia and Ukraine in the global food system and the impact of the Russia–Ukraine conflict on food security. It also highlights how diversifying four areas of agrifood systems—markets, production, crops, and technology can contribute to achieving food supply chain resilience for future food security and sustainability.

“…Additionally, they are a low-cost source of protein, minerals, and vitamins; they represent a source of nutrition for many centuries in Asia, Africa, Central, and South America. Furthermore, the genus Amaranthus has a diverse genetic pool and has the ability to withstand drought stress, making it an ideal crop for ensuring nutritional security in a climate-changing planet ( Jamalluddin et al, 2021 ). From a medical perspective, the crude extract of Amaranthus plants contains alkaloids (betacyanins and betaxanthin), polyphenols (flavonoids, steroids, catechuic acid, and tannins), terpenoids (cerasinone and norecasantalic acid), and saponins depending on the plant maturity stage, cultivar type, and geographical location ( Peter & Gandhi, 2017 ).…”

The present work aimed at differentiating five Amaranthus species from Saudi Arabia according to their morphology and the ability in nanoparticle formulation. Biogenic silver nanoparticles (AgNPs) were synthesized from leaf extracts of the five Amaranthus species and characterized by different techniques. Fourier-transform infrared spectroscopy (FT-IR) was used to identify the phyto-constituents of Amaranthus species. The nanoparticles (NPs) were characterized by UV-visible spectroscopy, dynamic light scattering (DLS), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX). The antibacterial activity of the synthesized NPs was tested against Staphylococcus aureus, E. coli, Klebsiella pneumoniae and Pseudomonas aeruginosa using the agar well diffusion method. Spherical NPs varying in size and functional groups from the five plant species were demonstrated by TEM, DLS and FTIR analysis, respectively. Variations in NPs characteristics could be related to the phytochemical composition of each Amaranthus species since they play a significant role in the reduction process. EDX confirmed the presence of Ag in plant fabricated AgNPs. Antibacterial activity varied among the species, possibly related to the NPs characteristics. Varied characteristics for the obtained AgNPs may reflect variations in the phytochemical composition type and concentration among Amaranthus species used for their fabrication.

Amaranth (Amaranthus spp.) is a highly nutritious, underutilized vegetable and pseudo-cereal crop. It possesses diverse abiotic stress tolerance traits, is genetically diverse and highly phenotypically plastic, making it an ideal crop to thrive in a rapidly changing climate. Despite considerable genetic diversity there is a lack of detailed characterization of germplasm or population structures. The present study utilized the DArTSeq platform to determine the genetic relationships and population structure between 188 amaranth accessions from 18 agronomically important vegetable, grain, and weedy species. A total of 74, 303 SNP alleles were generated of which 63, 821 were physically mapped to the genome of the grain species A. hypochondriacus. Population structure was inferred in two steps. First, all 188 amaranth accessions comprised of 18 species and second, only 120 A. tricolor accessions. After SNP filtering, a total of 8,688 SNPs were generated on 181 amaranth accessions of 16 species and 9,789 SNPs generated on 118 A. tricolor accessions. Both SNP datasets produced three major sub-populations (K = 3) and generate consistent taxonomic classification of the amaranth sub-genera (Amaranthus Amaranthus, Amaranthus Acnida and Amaranthus albersia), although the accessions were poorly demarcated by geographical origin and morphological traits. A. tricolor accessions were well discriminated from other amaranth species. A genome-wide association study (GWAS) of 10 qualitative traits revealed an association between specific phenotypes and genetic variants within the genome and identified 22 marker trait associations (MTAs) and 100 MTAs (P≤0.01, P≤0.001) on 16 amaranth species and 118 A.tricolor datasets, respectively. The release of SNP markers from this panel has produced invaluable preliminary genetic information for phenotyping and cultivar improvement in amaranth species.
