“…Nevertheless, the recent technological breakthroughs in the fields of phenotyping, DNA sequencing and molecular‐assisted breeding are increasingly facilitating the use of these genetic resources for crop improvement. For example, quinoa ( Chenopodium quinoa ), an undomesticated pseudo‐cereal that has gained popularity in developed countries due to its nutritional potential (Cheng, ), displays substantial genetic and phenotypic diversity (Figure ), including accessions with high tolerance to salt stress (Jacobsen et al ., ). The recent publication of two high‐quality quinoa genomes, alongside genomic data for a growing number of accessions and close relatives, provides great promise for detecting the genetic components underlying this species’ elevated salt tolerance (Jarvis et al ., ; Zou et al ., ).…”

Summary Salt stress limits the productivity of crops grown under saline conditions, leading to substantial losses of yield in saline soils and under brackish and saline irrigation. Salt tolerant crops could alleviate these losses while both increasing irrigation opportunities and reducing agricultural demands on dwindling freshwater resources. However, despite significant efforts, progress towards this goal has been limited, largely because of the genetic complexity of salt tolerance for agronomically important yield‐related traits. Consequently, the focus is shifting to the study of traits that contribute to overall tolerance, thus breaking down salt tolerance into components that are more genetically tractable. Greater consideration of the plasticity of salt tolerance mechanisms throughout development and across environmental conditions furthers this dissection. The demand for more sophisticated and comprehensive methodologies is being met by parallel advances in high‐throughput phenotyping and sequencing technologies that are enabling the multivariate characterisation of vast germplasm resources. Alongside steady improvements in statistical genetics models, forward genetics approaches for elucidating salt tolerance mechanisms are gaining momentum. Subsequent quantitative trait locus and gene validation has also become more accessible, most recently through advanced techniques in molecular biology and genomic analysis, facilitating the translation of findings to the field. Besides fuelling the improvement of established crop species, this progress also facilitates the domestication of naturally salt tolerant orphan crops. Taken together, these advances herald a promising era of discovery for research into the genetics of salt tolerance in plants.

“…Currently, food researchers are committed to developing the gluten-free food with just the apropos taste and the texture that would be accepted by consumers, which is a challenging and time-consuming task (Cheng, 2018;Teresa, Silvia, Furio, & Nicoletta, 2015). In baking, the main flow of gluten-free bread is very soft dough (Granza et al, 2018).…”

The viscoelastic properties of soy protein isolate (SPI) were investigated by creep–recovery under creep time (75 s, 150 s, 300 s, and 600 s), shear stress (1 Pa, 6 Pa, 10 Pa, and 20 Pa), and creep temperature (25°C, 50°C, and 80°C). Creep compliance (JC) increased proportionally with creep time from 75 to 600 s and with stress from 1 to 20 Pa, it decreased proportionally with temperature from 25 to 80°C. Results showed that the flow behavior of SPI varied along with creep time, stress, and temperature. Creep compliance data were best‐fitted to 4‐element Burgers model (R2 > .94), the instantaneous compliance (J0), retardation compliance (J1), retardation time (r1), steady‐state viscosity (η0), and recovery (%) have significant changes with creep time, stress, and temperature (p < .05). Adding maltodextrin (MD) accelerated the deformation of SPI. The flexibility and rigidity of SPI molecular chains was dependent on creep time, stress, and temperature. Practical applications In this research paper, we studied the viscoelasticity of SPI using the creep–recovery analysis. The chain flexibility, rigidity, and viscidity of SPI molecules were discussed at creep time, shear stress, and creep temperature. At the same time, the viscoelasticity of SPI adding of MD is also discussed. According to the experiment, this study provides new insights into the viscoelastic properties of SPI and builds a fundamental foundation for the comprehensive utilization of SPI in the food industry.

“…However, it is important to note that the production of the modern varieties requires the utilization of a substantial amount of chemical fertilizers and pesticides, with the adoption of efficient irrigation systems to boot [39,40]. Another major issue of growing modern varieties is the increase in monoculture, continuous cultivation of a uniform crop variety on a particular land, which reduces the genetic diversity of crops and agricultural system, thus increasing the crop vulnerability to agricultural risks, notably disease and pest infestation [1,34].…”

“…With the constant rise in food demand and rapid changes in consumption patterns, radical research approaches are crucial to complement fundamental exploration in improving both major and underutilized (or orphan and neglected) plant species [72,73]. In fact, the past decade saw the emergence of multiple studies on the lesser known plants as one of the prime strategies in strengthening the four pillars of food security, which include the availability, access, utilization, and stability of food [1,74].…”

Agriculture, the largest user of natural resources like water and land in the world, plays a direct role in achieving some of the 17 developed SDGs, especially in terms of water, biodiversity, climate change, poverty, sustainable energy, and cities [3].…”

Rice, the first crop to be fully sequenced and annotated in the mid-2000s, is an excellent model species for crop research due mainly to its relatively small genome and rich genetic diversity. The 130-million-year-old cereal came into the limelight in the 1960s when the semi-dwarfing gene sd-1, better known as the "green revolution" gene, resulted in the establishment of a high-yielding semi-dwarf variety IR8. Deemed as the miracle rice, IR8 saved millions of lives and revolutionized irrigated rice farming particularly in the tropics. The technology, however, spurred some unintended negative consequences, especially in prompting ubiquitous monoculture systems that increase agricultural vulnerability to extreme weather events and climate variability. One feasible way to incorporate resilience in modern rice varieties with narrow genetic backgrounds is by introgressing alleles from the germplasm of its weedy and wild relatives, or perhaps from the suitable underutilized species that harbor novel genes responsive to various biotic and abiotic stresses. This review reminisces the fascinating half-century journey of rice research and highlights the potential utilization of weedy rice and underutilized grains in modern breeding programs. Other possible alternatives to improve the sustainability of crop production systems in a changing climate are also discussed.
