Abstract:
... Physical barriers hinder about 20–25% of the protein from being extracted from whole meal. Heat-induced denaturation and aggregation of protein in quinoa seeds and in whole meal was investigated. Maximally 37% of the protein in seeds covalently aggregate when boiling for 15 min. Although embryonic cell walls surrounding protein bodies remain intact during boiling of seeds, protein aggregation is n ...

Abstract:
... Vascular connection is key to successful graft. Little study has been devoted to the behavior of tracheary elements (TEs), the basic component of vascular bundles, during vascular connection between scion and rootstock. Here we report the structural changes of TEs at the graft interface between two quinoa cultivars, Qaidam White-1 (QW1) and Qaidam Red-1 (QR1). Our results showed that TEs in ungraf ...

Abstract:
... The ability of some halophytic plants such as Chenopodium quinoa to sequester large quantities of salt into epidermal bladder cell (EBC) is considered as one of the traits conferring their salinity stress resilience. In the current study, we used mRNA-seq to characterize transcriptome differences between intact and EBC-free quinoa leaves from plants that were treated with 400 mM NaCl for 4 weeks. ...

Expansion into areas outside their centres of origin requires knowledge of quinoa's physiology and its response to the environment concerning the determination of seed yield and its numerical components to facilitate crop management and breeding. The objectives of the current work were to analyse the determination of seed weight (SW) of different quinoa genotypes adapted to temperate climates (Sea ...
... The survival and adaptation of angiosperms depends on the proper timing of flowering. The weedy species Chenopodium ficifolium serves as a useful diploid model for comparing the transition to flowering with the important tetraploid crop Chenopodium quinoa due to the close phylogenetic relationship. The detailed transcriptomic and hormonomic study of the floral induction was performed in the short- ...

Abstract:
... Soils salinization along with heavy metals contamination is among the serious environmental menaces. The present experiment was conducted to study the combined influence of salinity and nickel (Ni) on growth and physiological attributes of quinoa (Chenopodium quinoa Willd.). Thirty-day-old healthy and uniform seedlings of quinoa genotype A7 were exposed to different concentrations of Ni (0, 100, 2 ...
... BACKGROUND: Quinoa is an increasingly popular seed crop frequently studied for its tolerance to various abiotic stresses as well as its susceptibility to heat. Estimations of quinoa pollen viability through staining methods have resulted in conflicting results. A more effective alternative to stains is to estimate pollen viability through in vitro germination. Here we report a method for in vitro ...

Abstract:
... Quinoa (Chenopodium quinoa) is an important crop that is used as a model host for studying plant viruses. Genome sequences of five partitiviruses (two novel betapartitiviruses, two novel deltapartitiviruses, and one known gammapartitivirus) were identified from 65 quinoa transcriptome datasets. All quinoa transcriptome datasets analyzed in this study contained at least one of these partitivirus ge ...

Abstract:
... Quinoa panicle rot (QPR) is a novel disease that poses a significant threat to quinoa production in China. Typical symptoms on panicles include a film of pale pink, grey‐white, or dark brown mould on the grains during the grain‐filling stage. Furthermore, QPR causes quinoa grain discolouration, unfilling, and malformation. In total, 37 isolates were identified as belonging to three species: Tricho ...

Microwave roasting significantly (p < .05) varied the WAC (1.04 to 1.41 g/g), OAC (1.09 to 0.96 g/g), FC (6.66% to 4.62%), EC (57.06% to 43.18%), and pasting properties of quinoa. Roasted quinoa samples are rich in TPC (78.54 to 105.9 mg GAE/100 g) and AO ...
... Replacement of conventional feedstuffs with inexpensive and non-conventional ingredients such as quinoa may improve animal performance and the quality of their products. Quinoa supplementation is believed to have a good nutritive value as a ruminant feed, but evidence is scarce. The present experiment aimed to evaluate the nutritive value of whole, dried quinoa plant (Chenopodium quinoa) as a feed ...

Abstract:
... Quinoa has a high nutraceutical potential because of the presence of secondary metabolites called saponins, which have industrial and medicinal uses and protect against attacks by pathogens. These compounds are found especially in the seed coat and give the grain a bitter taste; therefore, they must be eliminated before consumption. Despite the potential use in Colombia, there are few studies aime ...
