Rice embryos are rich in high-quality protein, lipid, vitamins and minerals, representing the most important nutritional part of brown rice. However, the molecular mechanism of rice embryo development is poorly understood. In this study, two rice cultivars with contrasting embryo size (the giant embryo cultivar Dapeimi and the normal embryo cultivar 187R) were used to explore excellent genes controlling embryo size, and the developed near-isogenic lines (NILs) (NIL-D, which has the giant embryo phenotype, and its matching line, NIL-X) were used to explore transcript and metabolic properties in the earlier maturation stage of giant embryo development under natural conditions. The map-based cloning results demonstrated that Dapeimi is a novel allelic mutant of the rice GIANT EMBRYO (GE) gene, and the functional mutation site is a single cytosine deletion in the exon1. A total of 285 differentially accumulated metabolites (DAMs) and 677 differentially expressed genes (DEGs) were identified between NIL-D and NIL-X. The analysis of DAMs indicated that plants lacking GE mainly promoted energy metabolism, amino acid metabolism, and lipid metabolism pathways in the rice embryo. Pearson correlation coefficient showed that 300 pairs of gene-metabolites were highly correlated. Among them, OsZS_02G0528500 and OsZS_12G0013700 were considered to be key genes regulating L-Aspartic acid and L-Tryptophan content during rice giant embryo development, which are promising to be good candidate genes to improve rice nutrition. By analyzing rice embryo development through a combination of strategies, this research contributes to a greater understanding of the molecular mechanism of rice embryo development, and provides a theoretical foundation for breeding high-nutrition varieties.

“…By means of non-targeted metabonomics analysis, the metabolites in embryonic rice of giant embryo rice "Shangshida 5" and common cultivated rice "Chao 2-10" were compared. It was found that the content of beta-alanine in " Shangshida 5" was 18.71 times higher than that in "Chao 2-10" (Guo et al, 2019). The contents of 8 vitamin E homologues in brown rice, endosperm of common cultivated rice and "Shangshida 5" were determined by high performance liquid chromatography.…”

Giant embryo rice is a special kind of functional rice which can produce eutrophic rice. It conforms to people's concept of food consumption and healthy life. Giant embryo rice and its intensively processed products have been widely used in food, medicine, health products and other fields. They have extremely important scientific significance and economic value, and have become one of the most nutritional and health-care functional rice in the future. In recent years, a series of important advances have been made in the research of giant embryo rice. The special nutrients, agronomic characteristics and products developed by giant embryo rice have attracted the attention of rice breeders and consumers at home and abroad. In this paper, the research contents and new advances in the creation and breeding of giant embryo rice germplasm, the characteristics of nutrient changes, important agronomic traits and the processing and utilization of giant embryo rice were summarized, and the application prospect of giant embryo rice was prospected, all of which could provide important reference for the development and sustainable utilization of giant embryo rice.

“…Understanding of natural variations and underlying mechanisms as well as factors governing temporal and spatial change patterns is fundamental for the identification of key metabolites for rational food quality design on nutritional and sensory quality of edible crop parts, including seeds, fruits, and tubers. Plant metabolomics has been widely used to investigate metabolomes of mature and developing seeds in several major food crops, particularly in rice [ 60 , 61 , 62 , 63 , 64 ], allowing us to understand what we eat, how they are formed, and how they are changed in the process of food crop development and food processing. Plant metabolomics studies have been also employed to identify common and/or specific macro- and micro-nutrients and quality associated components in food crops [ 32 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 ], their availability after cooking [ 70 , 72 , 73 ], and to discover biomarkers for future crop quality improvement.…”

“…Metabolomics (GC-MS and UHPLC-MS/MS) has been used to elucidate nutritional traits of newly released rice cultivars as well, in which the giant embryo rice “Shangshida No. 5” is found to contain more nutrients and bioactive compounds (such as reduced arabinose, β-alanine, glutathione, VB6, xylitol, and xylose) in addition to previous known GABA than its control cultivar “Chao2-10” [ 64 ], rendering “Shangshida No. 5” a suitable cultivar for potential rice improvement for nutritional quality.…”

Plant metabolomics plays important roles in both basic and applied studies regarding all aspects of plant development and stress responses. With the improvement of living standards, people need high quality and safe food supplies. Thus, understanding the pathways involved in the biosynthesis of nutritionally and healthily associated metabolites in plants and the responses to plant-derived biohazards in humans is of equal importance to meet people’s needs. For each, metabolomics has a vital role to play, which is discussed in detail in this review. In addition, the core elements of plant metabolomics are highlighted, researches on metabolomics-based crop improvement for nutrition and safety are summarized, metabolomics studies on plant natural products including traditional Chinese medicine (TCM) for health promotion are briefly presented. Challenges are discussed and future perspectives of metabolomics as one of the most important tools to promote human nutrition and health are proposed.
