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: The global use of nitrogen fertilizers has increased significantly, but a large amount of nitrogen is lost to the environment. Modifying the distribution of organic nitrogen within plants can enhance grain yield and protein content with reduced fertilizer inputs. Biotechnological approaches, such as manipulating amino acids and ureides distribution, have been successful in improving nitrogen remobilization efficiency in crops. Further research is needed to understand the contribution of other nitrogen recycling mechanisms in crops.

Summary: A genetic framework for salinity tolerance in wheat at the reproductive stage was revealed using genome-wide SNP markers and major adaptability genes. The trait-associated loci were used to predict phenotypes, and their effects were validated. The study also identified loci associated with salt tolerance in synthetic-derived wheat lines and compared them to modern bread wheat lines. Functional genes related to salt tolerance were uncovered, and a genetic interaction network was constructed to reveal correlations among the investigated traits.

Summary: Priming plants to mild elevated temperature improves their tolerance to high-temperature stress later, and this tolerance is maintained for an extended period of time, known as thermomemory. NAC transcription factors ATAF1 and ANAC055 play a core role in thermomemory, with ATAF1 negatively regulating thermomemory and ANAC055 potentially co-regulating it.

Summary: Despite significant advances in understanding salinity tolerance, the application to improve salt tolerance in crops remains limited. Intraspecific and distant relatives' traits introgression have been utilized, but difficulties in introgression and yield penalties still hinder progress. The main limitation is that salinity tolerance is not a primary trait for breeders. Efforts are needed to bridge the gap between research and practical application, such as reassessing old techniques and exploring domestication of salt-tolerant wild species.

Summary: Wheat is a major food source for humans globally, but sustainable strategies are needed to keep up with increasing food demand. Salinity stress affects wheat growth and yield negatively. The AtCIPK16 gene has been identified as an important gene in Arabidopsis thaliana that responds to salinity stress. In this study, the AtCIPK16 gene was cloned into plant expression vectors and transformed into local wheat cultivars. The transgenic wheat lines expressing AtCIPK16 showed better tolerance to salinity stress and higher K+ retention in root tissues compared to the wild type.

Summary: Excessive evaporative loss of water in arid-land agriculture threatens food-water security. Researchers have developed biodegradable superhydrophobic sand (SHS) as a solution to reduce evaporation and increase soil moisture. Field trials have shown that SHS mulch can significantly enhance crop yields, especially under brackish water irrigation. Additionally, SHS technology does not affect the soil-root-rhizosphere microbial communities.
