Abstract: Starch is the most important component in potato tubers, whose structure and composition play key roles in properties of potato storage, processing, and applications. This review identifies the bio ersity of starch content, structure, and physiochemical properties, particularly the amylose and amylopectin content, molecular and granular structure, gelatinization, retrogradation, swelling power, solubility, and digestibility of potato in the past decade. Various functions of major potato starch biosynthesis‐related enzymes, such as AGPase, starch synthase, starch branching enzyme, debranching enzyme, and glucan/water dikinase, are also summarized. The potential utilization of native and modified potato starch in food and medicine fields owing to its high pasting viscosity is also analyzed. This review will contribute to a better understanding of the genetics–structure–functions of potato starch and may provide insights into potential potato starch utilization and further genetic improvement of starch quality.

Abstract: It is known that lysophospholipids (LPLs) may affect rice starch pasting and thermal properties possibly through the formation of an amylose-lipid complex. However, whether these effects of rice LPLs are independent of amylose are still not understood. Here, the ersity of rice flour pasting and thermal properties and their relationship with in idual LPL components in native rice endosperm were studied. Several significant correlations between LPLs and pasting properties, such as cool paste viscosity (CPV), breakdown (BD) and consistency (CS) were clearly evident. Thermal properties generally had no relationship with LPLs except for gelatinization enthalpy. Using partial correlation analysis we found that, irrespective of apparent amylose content, CPV and in idual LPLs were positively correlated, while BD, CS and other in idual LPLs were negatively correlated. This study suggests naturally occurring in idual LPLs can contribute to rice flour pasting and thermal properties, either independently or in combination with amylose.

Abstract: Mineral elements in brown rice grain play an important role in human health. In this study, variations in the content of iron (Fe), zinc (Zn), selenium (Se), cadmium (Cd), and lead (Pb) in 378 accessions of brown rice were investigated, and association mapping was used to detect the quantitative trait loci (QTLs) responsible for the variation. Among seven subpopulations, the mean values of Zn and Cd in the japonica group were significantly higher than in the indica groups. The population structure accounted for from 5.7% (Se) to 22.1% (Pb) of the total variation. Correlation analyses showed that Pb was positively correlated with the other minerals (P < 0.001) except for Se. For the five mineral elements investigated, 20 QTLs, including some previously reported and new candidate loci, were identified. Particularly, three cases of QTL colocalization, i.e. Cd and Pb on chromosome 5, Zn and Pb on chromosome 7, and Se and Pb on chromosome 11, were observed. This study suggested that the identified markers could feasibly be used to enhance desired micronutrients while reducing the heavy metal content in whole rice grain by marker-assisted selection (MAS).

Abstract: Phospholipids (PLs) play a prominent role in both grain cellular structure and nutritional function of cereal crops. Their lyso forms (lysophospholipids, LPLs) often combine with cereal starch to form an amylose-lipid complex (ALC), which may influence starch properties. In this study, 20 rice accessions were grown over two seasons at the same location to explore ersity in LPLs of milled rice. Levels of specific LPLs differed significantly among rice genotypes, demonstrating there is a wide ersity in LPLs in rice grain. The main LPL components were lysophosphatidylcholine (LPC) 16:0 (ranging from 3009.7 to 4697.8 μg/g), LPC18:2 (836.6-2182.3 μg/g), lysophosphatidylethanolamine (LPE) 16:0 (625.7-1139.8 μg/g), and LPE18:2 (170.6-481.6 μg/g). Total LPC, total LPE, and total LPL ranged from 4727.1 to 7685.2 μg/g, from 882.8 to 1809.5 μg/g, and from 5609.8 to 9401.1 μg/g, respectively. Although significant (P < 0.001) environment and genotype × environment (G × E) interactions were detected by analysis of variance (ANOVA), these effects accounted for only 0.7-38.9 and 1.8-6.6% of the total variance, respectively. Correlation analysis between LPL components provided insight into the possible LPL biosynthesis pathway in plants. Hierarchical cluster analysis suggested that the 20 rice accessions could be classified into three groups, whereas principal component analysis also identified three groups, with the first two components explaining 57.7 and 16.2% of the total variance. Further genetic studies are needed to identify genes or quantitative trait loci (QTLs) underlying the genetic control of LPLs in rice grain.

Abstract: Acquiring a complete understanding of rice starch lysophospholipids (LPLs), their biosynthetic pathways and genetic ersity, and the influence of genotype by environment interactions has been h ered by the lack of efficient high-throughput extraction and analysis methods. It was hypothesized a single-step aqueous n-propanol extraction combined with liquid chromatography-mass spectrometry (LC-MS) could be employed to analyze starch LPLs in white rice. The investigation found different grinding methods showed little effect on the final LPL detected, and a simple single-step extraction with 75% n-propanol (8 mL/0.15 g) heated at 100 °C for 2 h was as effective as an onerous multistep extraction method. A LC-MS method was optimized to simultaneously quantify 10 major LPLs in rice starch within 15 min. This method enables total and in idual starch LPL analysis of a large number of rice s les at little cost. This approach could be applied to starch LPLs in other cereals.

Abstract: Uncovering the genetic basis of polyphenol content and antioxidant activity traits in rice accessions is important to improve the nutritional quality of whole grain rice and to ameliorate the increasing nutrition problem of the rice-eating population. In this study, 20 erse rice accessions were planted in Hainan province, China, for 2 years to investigate the effects of genotype, environment, and their interactions on total phenolic (TPC), flavonoid (TFC), proanthocyanidins content (TPAC), ABTS, and DPPH radical scavenging activity by association mapping. Analyses of variance (ANOVA) showed that TPC, TFC, TPAC, ABTS, and DPPH were mainly affected by genetic variance, accounting for >94% of the total variance. The interaction between genotype × environment (G × E) was also highly significant (P 0.96 P < 0.001). Twenty-three putative unique loci were identified by association mapping. Five loci were close to previously identified genes or quantitative trait loci (QTLs). Among them, qPAC7-3 identified for TPAC in 2011 was near to the brown pericarp and seed coat (Rc) gene, and the locus at the qPC4/qFC4/qPAC4/qACA4/qACD4 cluster on chromosome 4 detected in two environments was near to a transcriptional activator A (Ra) gene. Some loci were identified in only one environment, indicating that these QTLs were sensitive to environment. This study provides a primary SNP-resource for further identification of genes responsible for polyhenol contents and antioxidant activity in rice whole grains.

Abstract: As a fundamental component of nucleic acids, phospholipids, and adenosine triphosphate, phosphorus (P) is critical to all life forms, however, the molecular mechanism of P translocation and distribution in rice grains are still not understood. Here, with the use of five different low phytic acid (lpa) rice mutants, the redistribution in the main P-containing compounds in rice grain, phytic acid (PA), lysophospholipid (LPL), and inorganic P (Pi), was investigated. The lpa mutants showed a significant decrease in PA and phytate-phosphorus (PA-P) concentration with a concomitant increase in Pi concentration. Moreover, defects in the OsST and OsMIK genes result in a great reduction of specific LPL components and LPL-phosphorus (LPL-P) contents in rice grain. In contrast, defective OsMRP5 and Os2-PGK genes led to a significant increase in in idual LPL components. The effect of the Os2-PGK gene on the LPL accumulation was validated using breeding lines derived from a cross between KBNT-lpa (Os2-PGK mutation) and Jiahe218. This study demonstrates that these rice lpa mutants lead to the redistribution of Pi in endosperm and modify LPL biosynthesis. Increase LPLs in the endosperm in the lpa mutants may have practical applications in rice breeding to produce "healthier" rice.

Abstract: Waxy (glutinous) rice is widely used in traditional foods, and understanding the genetic bases of its erse physicochemical properties will contribute to breeding of new waxy rice with unique qualities. The objective of this study was to investigate the genetic relationship between the starch biosynthesis related genes and the physicochemical properties of waxy rice using association mapping. A total of 36 molecular markers representing 18 genes were used to genotype 50 waxy rice accessions for which starch properties were previously available. Most of the starch properties differed between high and low gelatinization temperature (GT) groups, whereas most traits were similar between the low-GT indica rice and low-GT japonica rice, suggesting GT was the main determinant of the starch quality of waxy rice. Association mapping indicated that the starch properties of waxy rice were mainly controlled by starch synthase IIa (SSIIa or SSII-3, a major gene responsible for the gelatinization temperature) and SSI. It was found that gene-gene interactions were also important for the genetic control of starch properties of waxy rice. This study suggests that application of the functional SNPs of SSIIa in molecular breeding may facilitate quality improvement of waxy rice.

Abstract: Starch physicochemical properties determine the eating and cooking quality of rice. The genetic ersity in the apparent amylose content (AAC) and pasting viscosity parameters of 20 geographically erse rice accessions were investigated. It was found that AAC and pasting viscosities differed widely among different accessions, but each accession performed relatively stably across two environments. Analysis of variance (ANOVA) indicated that all traits were predominantly controlled by genotypic variance, but the genotype×environment interaction effects were also significant except for AAC and PT. Significant correlations were found for each parameter between 2years (P<0.001). Association mapping identified a total of 22 main-effect quantitative trait loci (QTLs) responsible for all traits except for CPV. This study showed that starch physicochemical properties of rice were highly stable and mainly controlled by genetic factors, and gave insight into the molecular improvement of eating quality using marker assisted breeding with the identified QTLs/genes.

Abstract: Twenty rice accessions were planted in Hainan province, China, for 2 years to investigate the effects of genotype, environment, and their interactions on the Ca, Mg, Na, K, Fe, Zn, and Cu contents in brown rice. Analysis of variance showed that the Ca, Na and K were mainly affected by the genotypic variance, whereas the Fe, Zn and Cu were mainly affected by the environment variance. The genotype × environment interaction effects for Mg, Na, Zn, and Cu were highly significant (P < 0.001), though it only accounted for a small proportion of the total variation (0.5-16.3%). The correlation analyses showed that Mg was significantly positively correlated with K, Fe, and Zn. A total of 9 and 8 single nucleotide polymorphism (SNP) loci were identified in 2011 and 2012, respectively, which were strongly associated with for Ca, Cu, K, Na, and Zn.
