“…Quinoa grains and leaves both contain a high content of phenolics, although the leaves have a higher protein content than the grains. The consumption of nutrient-rich green leaf quinoa can prevent nutritional deficiencies caused by iron and zinc, and there is higher saponin content in the grains compared with the leaves ( Pathan et al., 2019 ; Villacrés et al., 2022 ). Quinoa grains also contain sufficient micronutrients such as calcium, phosphorus, potassium, copper, iron, and zinc ( Ayasan, 2020 ).…”

The crop production of quinoa (Chenopodium quinoa Willd.), the only plant meeting basic human nutritional requirements, is affected by drought stress. To better understand the drought tolerance mechanism of quinoa, we screened the drought-tolerant quinoa genotype “Dianli 129” and studied the seedling leaves of the drought-tolerant quinoa genotype after drought and rewatering treatments using transcriptomics and targeted metabolomics. Drought-treatment, drought control, rewatering-treated, and rewatered control were named as DR, DC, RW, and RC, respectively. Among four comparison groups, DC vs. DR, RC vs. RW, RW vs. DR, and RC vs. DC, we identified 10,292, 2,307, 12,368, and 3 differentially expressed genes (DEGs), and 215, 192, 132, and 19 differentially expressed metabolites (DEMs), respectively. A total of 38,670 genes and 142 pathways were annotated. The results of transcriptome and metabolome association analysis showed that gene-LOC110713661 and gene-LOC110738152 may be the key genes for drought tolerance in quinoa. Some metabolites accumulated in quinoa leaves in response to drought stress, and the plants recovered after rewatering. DEGs and DEMs participate in starch and sucrose metabolism and flavonoid biosynthesis, which are vital for improving drought tolerance in quinoa. Drought tolerance of quinoa was correlated with gene expression differences, metabolite accumulation and good recovery after rewatering. These findings improve our understanding of drought and rewatering responses in quinoa and have implications for the breeding of new drought-tolerance varieties while providing a theoretical basis for drought-tolerance varieties identification.

“…However, it has not received adequate attention for its importance and unbelievable nutritional values, whereas public awareness of its value and potential does not yet exist (Shams, 2011;Eisa et al, 2017;Zohry, 2020;González et al, 2021). Quinoa has enormous potential; it is not only a gluten-free grain crop (Pereira et al, 2018;Villacrés et al, 2022), but it can also be used as a leafy greens crop (Abd El-Samad et al, 2018a; Pathan and Siddiqui, 2022), a fodder crop (Asher et al, 2020;Yilmaz et al, 2021) and in the food industry (Wang and Zhu 2016; Soliman et al, 2019).…”

It aimed to investigate the effect of applying potassium fertilizer at 90, 140 and 190 kg K 2 O/ha combined with spraying applications of seaweed extract for four times in a 15-day interval starting at 40 days after sowing at rates of 0.0, 1.5 and 3.0 ml/L on the yield, mineral contents and nutritional quality of quinoa grains cv. CICA. A split-plot design was used in three replicates. Results reported that by increasing the application of potassium from 90 to 190 kg K 2 O/ha, gradual increases in all studied parameters of quinoa grains occurred in the seasons of 2016-2017 and 2017-2018, except for class B grain, Mg and fiber contents. Potassium application at 190 kg K 2 O/ha gave the highest significant values of all determined parameters in comparison with treatment of 90 kg K 2 O/ha. In most cases, insignificant differences were detected between potassium fertilizer levels of 140 and 190 kg K 2 O/ha. Spraying seaweed extract at 3.0 ml/L resulted in superiority of all studied characters except class B grain, Mg and fiber contents, followed by 1.5 ml/L treatment with insignificant differences between them in most cases. There were significant differences among spraying seaweed treatments on Ca, Fe, Mn, protein and fiber contents in both seasons, N, P and K during the first season, and grain yield/plant, total grain yield/ha and Zn content during the second season. The interaction between potassium fertilization levels and spraying applications of seaweed extract had significantly different effects on all studied characters during both seasons, except for Mg percentage. It is evident that the application of potassium fertilization at 140 or 190 kg K 2 O/ha combined with the spraying of seaweed extract at 3.0 ml/L caused an apparent enhancement of the yield, mineral contents and nutritional quality of quinoa grains during the two experimental seasons.

“…Additionally, C. quinoa has exceptional nutritional qualities, wide genetic diversity and a great adaptation to different biotic and abiotic stress conditions, such as variable temperatures, high salt concentrations, water deficit, acidic or alkaline soils, among other 12 , 13 . Additionally, quinoa leaves and grains exhibit excellent potential for application in the food and pharmaceutical industries because they have an appreciable phenolic content, a higher content of the antinutrient saponin in the grain, and more nitrates and oxalates in the leaves 14 .…”

Quinoa is a plant commonly-resistance to adverse biotic and abiotic factors. However, this crop can be affected by phytopathogenic fungi. There is a lack of knowledge about the fungi associated with quinoa plants in Colombia. Through morphological and molecular identification in this study were identified four Fusarium species associated with quinoa crops: Fusarium oxysporum, Fusarium graminearum, Fusarium equiseti, and Fusarium culmorum. For this, we collected samples of panicles, leaf tissue, root tissue, and soil for isolation of different isolates of Fusarium. We performed a pathogenicity test of the fungi strains, under greenhouse conditions to evaluate the pathogenicity in seedlings of the Piartal cultivar with two inoculation methods. First inoculating the stem through a nodal wound or second inoculating the abaxial face with a brush. The results indicate the presence of four species with both molecular markers, phylogenetically distributed in these groups. The four species turned out to be pathogenic but with different degrees of virulence with significant differences between F. graminearum and F. oxysporum depending on the inoculation method. This is the first report on the presence of Fusarium species isolated from Quinoa in Colombia.
