Summary: We studied the stress response mechanism of quinoa, a dicotyledonous cereal, by subjecting it to different stress treatments. Through high-throughput sequencing, we identified known/novel genes and miRNAs in quinoa, and predicted their target genes involved in stress response. Our findings showed that reactive oxygen species homeostasis, hormone signaling, cell wall synthesis, transcription factors, and other factors play important roles in the abiotic stress response of quinoa.

Summary: This study compared the effects of osmotic, salt, and combined stress on the morphology and anatomy of photosynthetic organs in young quinoa plants. The results showed that salt stress of 100 to 200 mM NaCl did not have a critical impact on the growth of quinoa plants, while the plants were able to withstand salt stress at an intensity of 300 mM NaCl. However, adaptation mechanisms were violated at a salt stress intensity of 200 mM NaCl, and significant changes in water balance were observed at 300 mM NaCl, possibly due to damage to cell structures.

Summary: The halophyte quinoa responds to salinity stress by altering the protein composition of guard cells, with differential expression of proteins involved in signaling pathways and stress responses. Upregulated proteins in response to salt treatment include those related to ABA signaling and sucrose-starch metabolism, while high levels of aspartic proteinase are associated with mitigating oxidative stress induced by saline conditions.

Summary: Soil salinity, drought, and increasing temperatures have negative effects on crop productivity, with combined stress having a higher impact than individual stresses. This study found that the growth and yield of four quinoa genotypes were significantly decreased when exposed to combined drought, salinity, and high-temperature stress. The genotypes differed in their physiological and biochemical responses, with Puno and Titicaca showing higher tolerance compared to Vikinga. The findings highlight the importance of selecting and breeding quinoa varieties that can withstand multiple environmental stresses.
