BACKGROUND Most reports have indicated the antioxidant capacity of quinoa seeds. However, the leaves of Quinoa (Chenopodium quinoa Willd.) are usually worthless and little known about their biological activities. In this study, the antioxidant and immunomodulatory potential of the quinoa leaf extracts were explored. METHODS The crude leaf extracts of quinoa were extracted using water, 50% eth...

Quinoa is a pseudo-grain consumed as a dietary staple in South America. In recent years, consumer demand for quinoa in the developed world has grown steadily. Its perceived health benefits have been cited as a driving force behind this trend, but there are very few human studies investigating the impact of quinoa consumption. The aim of this review was to identify physiological effects of quino...

Despite the large interest in the use of Chenopodium quinoa as a crop on extreme habitats, very little is known about growth response and seed yield under saline conditions. As a prerequisite for its sustainable utilization in salt-affected areas, this study aimed to unravel individual physiological and morphological mechanisms that determine its salt tolerance. Hence, the plants were grown in ...

Heat-shock proteins (HSPs) are ubiquitous proteins with important roles in response to biotic and abiotic stress. The 70-kDa heat-shock genes (Hsp70s) encode a group of conserved chaperone proteins that play central roles in cellular networks of molecular chaperones and folding catalysts across all the studied organisms including bacteria, plants and animals. Several Hsp70s involved in drought ...

As sustainable production of quinoa (Chenopodium quinoa Willd.) increases and its geographic range of cultivation expands, quinoa breeding will allow use of the crop’s wide genetic diversity for cultivar improvement and for adaptation to new agroecosystems and climactic regimes. Such breeding work will require a reliable technique for crossing quinoa plants using hand emasculation. The techniqu...

Quinoa is a crop that originated from the Andes. It has high nutritional value, outstanding agro-ecological adaptability, and low water requirements. Quinoa is an excellent crop alternative to help overcome food shortages, and it can also have a role in the prevention of developed world lifestyle diseases, such as type-2 diabetes, cardiovascular diseases, osteoporosis, inflammatory and autoimmu...

Among potential climate change-adapted crops for future agriculture, quinoa (Chenopodium quinoa), a facultative halophyte plant with exceptional nutritional properties, stands out as a prime candidate. This work examined how quinoa deals with extreme situations during seed rehydration. Quinoa distinguishes itself from other plants in multiple ways. It germinates within minutes, even under extre...

The effect of Chenopodium quinoa seeds on lipid profile, glucose level, protein metabolism and selected essential elements (Na, K, Ca, Mg) level was determined in high-fructose fed male Wistar rats. Fructose decreased significantly LDL [42%, p<0.01] and activity of alkaline phosphatase [20%, p<0.05], and increased triglycerides level [86%, p<0.01]. The analysis of blood of rats fed quinoa indic...

Intraspecific variation in crop responses to global climate change conditions would provide opportunities to adapt crops to future climates. These experiments explored intraspecific variation in response to elevated CO₂ and to high temperature during anthesis in Chenopodium quinoa Wild. Three cultivars of quinoa were grown to maturity at 400 ("ambient") and 600 ("elevated") μmol·mol-1 CO₂ conce...

Cherry leaf roll virus (CLRV), Myrobalan latent ringspot virus (MLRSV) and Strawberry latent ringspot virus (SLRSV) were transferred by budding to woody trees, hybrid Ishtara, peach cv. GF 305 and cv. Lesiberian. Three buffers with antiox...
