“…The most attractive feature of sand rice is its edibility and nutritional value, although this underutilized crop has not yet been domesticated. The earliest reliable records of sand rice seed consumption, dating to the 7th century, documented that the seed was used as a supplement to the rations of soldiers and local shepherd‐nomads in China . To date, the indigenous people in northwestern China still keep sand rice seed on their menu, where it is consumed as porridge and cold starchy jelly.…”

BACKGROUND Sand rice (Agriophyllum squarrosum) is an underutilized pseudocereal bearing edible seeds. In this study, the phenolics and antioxidant activity of sand rice seeds after cooking and in vitro digestion were extensively investigated. RESULTS Total phenolic content (TPC) of the sand rice seeds was slightly increased whereas total flavonoid content (TFC) decreased after boiling. Furthermore, nine compounds were detected in the uncooked seeds, with hyperoside (169.19 ± 6.59 µg g−1 dry weight (DW)), protocatechuic acid (167.46 ± 7.21 µg g−1 DW), and rutin (83.15 ± 3.26 µg g−1 DW) as the major components. Apart from the bioaccessible phenolics in the aqueous fraction, these compounds retained in the solid residue of the porridge were released to varying degrees during simulated digestion. In addition, these phenolic extracts also exerted considerable antioxidant potency, which was positively correlated with their corresponding TPC, TFC, and phenolic profiles. CONCLUSION These results indicated that both boiling and in vitro digestive treatments could considerably enhance the release of bioactive compounds and thus contribute antioxidant properties to sand rice porridge. These findings suggest that sand rice seed is a potential functional food and an excellent natural antioxidant source. © 2019 Society of Chemical Industry

“…The negative influence of climate change on crop production has motivated scientists improve staple crops by exploitation of the genetic resource available in their wild relatives (Tester and Langridge, 2010; McCouch et al, 2013); however, the simultaneous development of new crops among the neglected and underutilized species will also crucial for sustainable and intensified food production (Mayes et al, 2012; Chen et al, 2014; Zhao et al, 2014). The Amaranthaceae species, sand rice ( Agriophyllum squarrosum ), has been among crops used for army provisions since the Tang Dynasty (AD 618–907) and is still an important component of local food for people inhabiting the Hexi Corridor along the ancient Silk Road in the northwest of China (Gao, 2002; Chen et al, 2014). Due to its high nutritional value and extreme stress tolerance, sand rice represents a suitable alternative food crop, resilient to climate change (Chen et al, 2014; Zhao et al, 2014).…”

“…To thrive in a desert environment, sand rice has evolved many morphological traits and adaptation strategies to mitigate the risk of extinction due to climate variability, such as extreme temperatures, unpredictable precipitation, strong solar radiation, and other environmental stresses (Chen et al, 2014; Zhao et al, 2014). Comparative transcriptome analysis has been used to identify candidate genes related to abiotic stress tolerance and unique traits of this species (Zhao et al, 2014, 2016).…”

The extreme stress tolerance and high nutritional value of sand rice (Agriophyllum squarrosum) make it attractive for use as an alternative crop in response to concerns about ongoing climate change and future food security. However, a lack of genetic information hinders understanding of the mechanisms underpinning the morphological and physiological adaptations of sand rice. In the present study, we sequenced and analyzed the transcriptomes of two individuals representing semi-arid [Naiman (NM)] and arid [Shapotou (SPT)] sand rice genotypes. A total of 105,868 pairwise single nucleotide polymorphisms (SNPs) distributed in 24,712 Unigenes were identified among SPT and NM samples; the average SNP frequency was 0.3% (one SNP per 333 base pair). Characterization of gene annotation demonstrated that variations in genes involved in DNA recombination were associated with the survival of the NM population in the semi-arid environment. A set of genes predicted to be relevant to heat stress response and agronomic traits was functionally annotated using the accumulated knowledge from Arabidopsis and several crop plants, including rice, barley, maize, and sorghum. Four candidate genes related to heat tolerance (heat-shock transcription factor, HsfA1d), seed size (DA1-Related, DAR1), and flowering (early flowering 3, ELF3 and late elongated hypocotyl, LHY) were subjected to analysis of the genetic diversity in 10 natural populations, representing the core germplasm resource across the area of sand rice distribution in China. Only one SNP was detected in each of HsfA1d and DAR1, among 60 genotypes, with two in ELF3 and four in LHY. Nucleotide diversity ranged from 0.00032 to 0.00118. Haplotype analysis indicated that the NM population carried a specific allele for all four genes, suggesting that divergence has occurred between NM and other populations. These four genes could be further analyzed to determine whether they are associated with phenotype variation and identify alleles favorable for sand rice breeding.

Agriophyllum squarrosum (L.) Moq. (A. squarrosum) is an annual fast‐growing psammophyte, producing large amounts of starchy seeds. To assess the potential application of this starch and increase the utilization of its flour, the composition, morphological, thermal, pasting, rheological, and textural properties of the starch are characterized by comparing with maize starch. The amylose content of the starch is 26.31%. Microscopy images reveal that the starch granules have a round shape and most of them are smaller than 1 µm in diameter. The X‐ray diffractogram exhibits a typical A‐type pattern, and the crystallinity is 36.75%. The gelatinization temperature and enthalpy are 64.26–77.60 °C and 14.29 J g−1, respectively. In contrast to maize starch, A. squarrosum starch has lower swelling power and solubility. RVA analysis shows a lower pasting viscosity and no break down at 95 °C. The starch has better cooking and shearing stability during heating and a lower tendency to retrograde during cooling and storage. Unique characteristics such as the extremely small size, and the excellent heating and shearing stability of the starch can contribute to special utilization in food or non‐food industries.
