To study the effect of the mixing, three types of starch from Dioscorea sp., Dioscorea piperifolia Humb.var. Wild. and Dioscorea Trífida tubers were mixed in different proportions and their thermal, structuraland rheological properties were characterised. Using thermogravimetric (TG) and differential thermalanalysis (DTA) it was found that all the mixed samples presented enhanced thermal stability. By differ-ential scanning calorimetry (DSC) and viscoamylograph (RVA) techniques it was verified that the amylosecontent from the D. sp. starch influenced the gelatinisation and paste properties of the mixed samples.Furthermore, using scanning electron micrograph (SEM) analysis it was possible to suggest a correlationbetween the size of the starch granules and their relative degree of crystallinity, which was calculatedby the X-ray diffraction (XRD) patterns. The colour analysis revealed that, irrespective of the proportion,the strong tendency to yellow of the native Dioscorea piperifolia predominated in the mixed samples. |

Data integration using hierarchical analysis based on the central dogma or common pathway enrichment analysis may not reveal non-obvious relationships among omic data. Here, we applied factor analysis (FA) and Bayesian network (BN) modeling to integrate different omic data and complex traits by latent variables (production, carcass, and meat quality traits). A total of 14 latent variables were identified: five for phenotype, three for miRNA, four for protein, and two for mRNA data. Pearson correlation coefficients showed negative correlations between latent variables miRNA 1 (mirna1) and miRNA 2 (mirna2) (-0.47), ribeye area (REA) and protein 4 (prot4) (-0.33), REA and protein 2 (prot2) (-0.3), carcass and prot4 (-0.31), carcass and prot2 (-0.28), and backfat thickness (BFT) and miRNA 3 (mirna3) (?0.25). Positive correlations were observed among the four protein factors (0.45?0.83): between meat quality and fat content (0.71), fat content and carcass (0.74), fat content and REA (0.76), and REA and carcass (0.99). BN presented arcs from the carcass, meat quality, prot2, and prot4 latent variables to REA; from meat quality, REA, mirna2, and gene expression mRNA1 to fat content; from protein 1 (prot1) and mirna2 to protein 5 (prot5); and from prot5 and carcass to prot2. The relations of protein latent variables suggest new hypotheses about the impact of these proteins on REA. The network also showed relationships among miRNAs and nebulin proteins. REA seems to be the central node in the network, influencing carcass, prot2, prot4, mRNA1, and meat quality, suggesting that REA is a good indicator of meat quality. The connection among miRNA latent variables, BFT, and fat content relates to the influence of miRNAs on lipid metabolism. The relationship between mirna1 and prot5 composed of isoforms of nebulin needs further investigation. The FA identified latent variables, decreasing the dimensionality and complexity of the data. The BN was capable of generating interrelationships among latent variables from different types of data, allowing the integration of omics and complex traits and identifying conditional independencies. Our framework based on FA and BN is capable of generating new hypotheses for molecular research, by integrating different types of data and exploring non-obvious relationships.
