“…The effects of global climate change and its influence on the growth and productivity of crop plants are poised to promulgate significant socioeconomic impacts on the global population and the environment. A warming climate will be unsuitable for plant growth and productivity, because it reduces the soil's potential to capture and retain water and maintain its fertility [1,2]. These effects will not only be detrimental to the environment, but will advance tremendous strain on the entire ecosystem due to the multifaceted origins and variable impacts.…”

The global population is on the path of an increasing trajectory with a simultaneous decline in arable land resources through salinization and desertification that have resulted mainly from climate change and other anthropogenic activities. Rising temperatures will cause changes in the entire ecosystem, resulting in significant alterations in global climate paradigms and a threat to food security. This review focuses on how the highly resilient Chenopodium quinoa Willd. can sustainably mitigate some of the detrimental impacts, such as starvation, and support or provide ecosystem services. In comparison, compared with the traditional staple food crops, quinoa has remarkable tolerance to abiotic stresses and is highly nutritious, with a unique balance and higher amounts of nutrients, and can therefore be an important crop for food security and nutritional adequacy. This crop has the potential to ameliorate global challenges with respect to increase in global population, effects of climate change, desalinization, phytoremediation, satisfying nutrient deficiency, and alleviating poverty.

Chenopodium quinoa Willd. (quinoa) originated from the Andean region of South America, and is a pseudocereal crop of the Amaranthaceae family. Quinoa is emerging as an important crop with the potential to contribute to food security worldwide and is considered to be an optimal food source for astronauts, due to its outstanding nutritional profile and ability to tolerate stressful environments. Furthermore, plant pathologists use quinoa as a representative diagnostic host to identify virus species. However, molecular analysis of quinoa is limited by its genetic heterogeneity due to outcrossing and its genome complexity derived from allotetraploidy. To overcome these obstacles, we established the inbred and standard quinoa accession Kd that enables rigorous molecular analysis, and presented the draft genome sequence of Kd, using an optimized combination of high-throughput next generation sequencing on the Illumina Hiseq 2500 and PacBio RS II sequencers. The de novo genome assembly contained 25 k scaffolds consisting of 1 Gbp with N50 length of 86 kbp. Based on these data, we constructed the free-access Quinoa Genome DataBase (QGDB). Thus, these findings provide insights into the mechanisms underlying agronomically important traits of quinoa and the effect of allotetraploidy on genome evolution.

“…Quinoa was chosen as a suitable candidate for this study because it exhibits the attributes of drought resistance, sustainability in the context of global changes and high economic potential (Gonz alez, Eisa, Hussin, & Prado, 2015). Unfortunately, no reports are available on the potential application of P. indica root symbiosis on C. quinoa up to now.…”

This study aimed to evaluate the ability of Piriformospora indica to colonize the root of Chenopodium quinoa and to verify whether this endosymbiont can improve the growth, performance and drought resistance of this species. The study delivered, for the first time, evidence for successful colonization of P. indica in quinoa. Hence, pot experiment was conducted in the greenhouse, where inoculated and non-inoculated plants were subjected to ample (40%-50% WHC) and deficit (15%-20%WHC) irrigation treatments. Drought adversely influenced the plant growth, leading to decline the total plant biomass by 74%. This was linked to an impaired photosynthetic activity (caused by lower g s and C i /C a ratio; stomatal limitation of photosynthesis) and a higher risk of ROS production (enhanced ETR/A gross ratio). P. indica colonization improved quinoa plant growth, with total biomass increased by 8% (controls) and 76% (drought-stressed plants), confirming the growth-promoting activity of P. indica. Fungal colonization seems to diminish drought-induced growth hindrance, likely, through an improved water balance, reflected by the higher leaf w w and g s .Additionally, stomatal limitation of photosynthesis was alleviated (indicated by enhanced C i /C a ratio and A net ), so that the threat of oxidative stress was minimized (decreased ETR/A gross ). These results infer that symbiosis with P. indica could negate some of the detrimental effects of drought on quinoa growth, a highly desired feature, in particular at low water availability.
