Apparent Amylose Content (AAC), regulated by the Waxy gene, represents key determinant of rice cooking properties. In occidental countries high AAC most requested market class but availability molecular markers allowing specific selection varieties is limited.In this study, effectiveness available in predicting was evaluated a collection 127 accessions (125 japonica ssp. and 2 indica ssp.) characterized values from glutinous to 26%. The analyses highlighted presence several different allelic...
Although most rice cultivars have whitish kernel, some varieties a red testa. Aim of this work was to compare the total antioxidant capacity (TAC) and chemical composition (namely tocols, gamma-oryzanols, polyphenols) white rices. In addition, effect milling cooking on antioxidants investigated in both Dehulled showed TAC more than three times greater dehulled its high essentially characterized by presence proanthocyanidins (PA) associated phenolics. Milling caused significant loss TAC, even...
Rice quality is mainly related to the following two starch components, apparent amylose content (AAC) and resistant (RS). The former affects grain cooking properties, while RS acts as a prebiotic. In present study, Genome Wide Association Scan (GWAS) was performed using 115 rice japonica accessions, including tropical temperate genotypes, with purpose of expanding knowledge genetic bases affecting AAC. High phenotypic variation recorded for traits, which positively correlated. Moreover, both...
The relationship between ethylene production and both seed dormancy germination was investigated using red rice (weedy rice) as a model species. Both fully dormant after-ripened (non-dormant) naked caryopses were incubated with or without inhibitors of synthesis [aminoethoxyvinylglycine (AVG)] perception [silver thiosulfate (STS)], in the presence natural precursor 1-aminocyclopropane-1-carboxylic acid (ACC). kinetics emissions measured sensitive laser–photoacoustic system. Dormant did not...
The aim of this research was to evaluate β-glucan-enriched flours, obtained from barleys with either normal or waxy starch, for their effects on the glycaemic index (GI) and quality bread. Rheological results confirmed that when barley flour included in dough overall bread slightly worsened. However, positive consequences glycaemia were starch barley: GI all-wheat (82.8 ± 7.2) significantly reduced (57.2 7.9) 40% wheat substituted (6.0% 0.1 β-glucan final blend). In contrast, effect (GI:...
Abscisic acid (ABA) is commonly assumed to be the primary effector of seed dormancy, but conclusive evidence for this role lacking. This paper reports on relationships occurring in red rice between ABA and dormancy. Content free dry imbibed caryopses, both dormant after-ripened, effects inhibitors, ability applied revert dormancy breakage were considered. The results indicate: (i) no direct correlation content with status seed, either or imbibed; (ii) different sensitivity non-dormant that...
Germination data are discrete and binomial. Although analysis of variance (ANOVA) has long been used for the statistical these data, generalized linear mixed models (GzLMMs) provide a more consistent theoretical framework. GzLMMs suitable final germination percentages (FGP) as well longitudinal studies time-courses. indices (i.e., single-value parameters summarizing results assay by combining level rapidity germination) other with Gaussian error distribution can be analyzed too. There are,...
Red rice fully dormant seeds do not germinate even under favorable germination conditions. In several species, including rice, seed dormancy can be removed by dry-afterripening (warm storage); thus, and non-dormant compared for the same genotype. A weedy (red) genotype with strong was used mRNA expression profiling, RNA-Seq, of dehulled caryopses (here addressed as seeds) at two temperatures (30 °C 10 °C) durations incubation in water (8 h 8 days). Aim study to highlight differences...
Rice represents one the most important foods all over world. In Europe, Italy is first rice producer and Italian production driven by tradition quality. All main grain quality traits, like cooking properties, texture, gelatinization temperature, chalkiness yield, are related to content composition of starch seed-storage proteins in endosperm shape. addition, a number nutraceutical compounds allergens known have significant effect on determination. To investigate genetic bases underlying...
Abstract Red rice ( Oryza sativa L.) dispersal units (florets) were dry-afterripened for 0–8 weeks and subsequently incubated at 30°C in polyethylene glycol (PEG) solutions with water potentials from 0 to − 1.6 MPa. Germination percentages rates increased dry-afterripening potential of the incubation medium. The seed population exhibited a normal distribution base (Ψ b , i.e. minimum allowing germination) among individual seeds, characterized by three parameters: hydrotime constant (θ H ),...
BACKGROUND: Structurally different areas may occur in the endosperm of barley grain, and they can be visually classified as either mealy or steely. Barleys with a high proportion grains that are mostly steely often show uneven physical–chemical modification during malting. To study relationship between steeliness modification, two samples cv. Scarlett contrasting malting quality were analysed. RESULTS: The proportions 77% 46% samples, which then defined sample sample, respectively. showed...
Abstract While red rice ( Oryza sativa L.) can remain dormant and viable for many years when fully imbibed, the environmental factors that stimulate germination or induce secondary dormancy in field have not been characterized. In this study, interactions between extent of dry-afterripening temperature evaluated as possible factors. Red dispersal units (florets) were afterripened 0–10 weeks at 30°C incubated water 1, 5, 15, 20, 25, 30 35°C 2 weeks; then, all ungerminated florets transferred...
Abstract Mapping quantitative trait loci (QTLs) responsible for malting quality traits in barley populations has been the main genetic approach to breeding. A ‘winter × spring’ doubled haploid population ‘Nure’ ‘Tremois’, where such were segregating, recently developed. Our objective was map QTLs from 2 years of trials two contrasting locations. found on six chromosomes, with a cluster chromosome 1H. For wort viscosity and malt extract, favourable alleles at 5H carried by winter feeding...
Naked barleys are less yielding than the hulled ones while reason for this difference has not been definitely clarified. To investigate effect of nud gene on yield, a barley doubled haploid (DH, Proctor × Nudinka) population was initially tested in three environments and QTL study run entire as well two nud/NUD DH subpopulations. Among agronomic traits studied, found at locus chromosome 7H only yield thousand grain weight (TGW), second 6H, although contributed by naked parent. Other QTLs TGW...
The genus Populus represents one of the most economically important groups forest trees. It is composed by approximately 30 species used for wood and non-wood products, phytoremediation biomass. Poplar subjected to several biological environmental threats although, compared annual crops, we know far less about genetic bases biotic stress resistance. Woolly poplar aphid (Phloeomyzus passerinii) considered a main pest cultivated poplars in European American countries. In this work present two...
Basic features of seed dormancy are illustrated. The overall regulatory network governs metabolism and development, it is coordinated by plant hormones. A functional model focused on abscisic acid (ABA), the foremost hormone in dormancy, used as a framework to critically discuss literature. Gibberellins (GAs) have main role germination, ABA – GAs balance typical feature state: dominates during prevail through germination. Thus, literature converges toward envisaging development switch...
