The WRKY gene family plays a unique role in plant stress tolerance. Quinoa is a cultivated crop worldwide that is known for its high stress tolerance. The WRKY gene family in quinoa has not yet been studied. Using a genome-wide search method, we identified 1226 WRKY genes in 15 plant species, seven animal species, and seven fungi species. WRKY proteins were not found in animal species and five fungi species, but were, however, widespread in land plants. A total of 92 CqWRKY genes were identified in quinoa. Based on the phylogenetic analysis, these CqWRKY genes were classified into three groups. The CqWRKY proteins have a highly conserved heptapeptide WRKYGQK with 15 conserved elements. Furthermore, a total of 25 CqWRKY genes were involved in the co-expression pathway of organ development and osmotic stress. The expression level of more than half of these CqWRKY genes showed significant variation under salt or drought stress. This study reports, for the first time, the findings of the CqWRKY gene family in quinoa at the genome-wide level. This information will be beneficial for our understanding of the molecular mechanisms of stress tolerance in crops, such as quinoa.

“…The expression profiles from CqHSFs genes were explored using RNA-seq data. Four CqHsfs upregulated in the expression profile were then validated in the salar ecotype ‘Real-Blanca’ under high temperature (37 °C), and the results showed that CqHsfs3 and CqHsfs9 had a higher expression level after 6 h of heat treatment, while CqHsfs4 and CqHsfs10 showed a higher expression level at 12 h [214].…”

Quinoa (Chenopodium quinoa Willd.) is a genetically diverse Andean crop that has earned special attention worldwide due to its nutritional and health benefits and its ability to adapt to contrasting environments, including nutrient-poor and saline soils and drought stressed marginal agroecosystems. Drought and salinity are the abiotic stresses most studied in quinoa; however, studies of other important stress factors, such as heat, cold, heavy metals, and UV-B light irradiance, are severely limited. In the last few decades, the incidence of abiotic stress has been accentuated by the increase in unpredictable weather patterns. Furthermore, stresses habitually occur as combinations of two or more. The goals of this review are to: (1) provide an in-depth description of the existing knowledge of quinoa’s tolerance to different abiotic stressors; (2) summarize quinoa’s physiological responses to these stressors; and (3) describe novel advances in molecular tools that can aid our understanding of the mechanisms underlying quinoa’s abiotic stress tolerance.

“…Expression of PDV MP gene (gene ID: HM015770.1) in quinoa was investigated at different times after inoculation in different parts of the plant (stem and leaves). As reference gene, we used quinoa actin (gene ID: LOC110724665) in quinoa, as suggested in [17]. Primers for reference and investigated genes were designed in Primer3 software v. 0.4.0 (Primer3Plus, Free Software Foundation, Inc., Boston, MA, USA).…”

Prune dwarf virus (PDV) is a plant RNA viral pathogen in many orchard trees worldwide. Our knowledge about resistance genes or resistant reactions of plant hosts to PDV is scant. To fill in part of this gap, an aim of this study was to investigate reactions to PDV infection in a model host, Chenopodium quinoa. Our investigations concentrated on morphological and ultrastructural changes after inoculation with PDV strain 0599. It turned out that PDV infection can cause deformations in host cells but also induce changes in the organelles, such as chloroplasts in inoculated leaves. Moreover, we also demonstrated specific reactions/changes, which could be associated with both types of vascular tissue capable of effectively blocking the systemic spread of PDV to upper leaves. Furthermore, the relative amount of virus, P1 protein deposition, and movement protein (MP) gene expression consequently decreased in PDV-inoculated leaves.
