1. Alternative methodologies for genotyping polymorphisms in the CAST and CAPN1 genes in beef cattle
ABSTRACT The objectives of this study were to genotype single nucleotide polymorphisms (SNP) AF159246:g.2959A>G (CAST/DdeI) and AF248054.2:g.6545C>T (CAPN4751) in beef cattle by PCR-RFLP (Polymerase Chain Reaction - Restriction Fragment Length Polymorphism), using the restriction enzyme DdeI for both SNP, and describe the use of these genotyping methodologie

2. Detection of Snps in the Melanocortin 1-Receptor (MC1R) and Its Association with Shank Color Trait in Hs Chicken
ABSTRACT The melanocortin 1 receptor (MC1R) gene plays a key role in controlling the deposition of melanin. In mammals, the MC1Rgene is regarded as a major candidate gene in the control of melanin formation. In domestic animals, the MC1R gene mainly controls the expression of coat, skin, and plumage color in mammals and birds. In order to breed chickens with

3. Genetic diversity and nonparametric statistics to identify possible ISSR marker association with fiber quality of pineapple
Abstract: Due to the increasing search for renewable resources, plant fibers have become an alternative when creating new products. Studies demonstrate the potential use of pineapple fibers in composites. The objective of this work was to evaluate the genetic diversity and verify any association between ISSR (Inter Simple Sequence Repeats) bands and quality

4. Development and validation of SNP assays for the selection of resistance to Meloidogyne incognita in soybean
Abstract This work aimed to develop and validate individual SNP molecular markers previously identified in a genetic association study of resistance to Meloidogyne incognita in soybean using a microarray panel. The markers identified in the array were converted in single TaqMan® markers. The single markers were used to create an SNP genotyping protocol and

5. Molecular marker assisted selection for increasing inbreeding in S1 populations of cassava
Abstract The objective of the present work was to use MAS in self-pollinated cassava populations for obtaining individuals with high inbreeding (f) aimed at rapid development of partial inbred lines. Three progenies (F0222, F1378 and F1662) were self-pollinated, generating a total of 233 S1 individuals. The progenies and the S1 individuals were evaluated in

6. Association of candidate genes for fatty acid content in soybean by temperature-switch PCR (TSP) genotyping
Abstract The development of molecular markers is essential for improvement of soybean cultivars with modified fatty acid content. The objective of this study was to identify and validate SNP markers in candidate genes for fatty acid content in soybean. Six candidate genes (ARAF, PDAT, ABI3, FAD2-1b, FAD3B, and FAD3C) were selected. Alignment of gene sequence

7. Allele dosage of PVY resistance genes in potato clones using molecular markers
Abstract Potato virus Y (PVY) is considered one of the most important pathogens in potato crop. The objective of this study was to estimate the allele dosage of Ry genes and select clones with multiple copies of resistance alleles to be used as parents in potato breeding programs. Seven clonal families were genotyped, including five parents with resistance t

8. Oleic acid variation and marker-assisted detection of Pervenets mutation in high- and low-oleic sunflower cross
Abstract High-oleic sunflower oil is in high demand on the market due to its heart-healthy properties and richness in monounsaturated fatty acids that makes it more stable in processing than standard sunflower oil. Consequently, one of sunflower breeder’s tasks is to develop stable high-oleic sunflower genotypes that will produce high quality oil. We analy

9. Polymorphisms and their Haplotype Combinations in the Lysozyme Gene Associated with the Production Traits of a Chinese Native Chicken Breed
ABSTRACT Animal lysozymes, which have been studied in many of invertebrate and vertebrate species, have been characterized and demonstrated to be immune-associated molecules, digestive enzymes and multifunctional molecules. The purpose of this study was to detect the connection between lysozyme-gene polymorphism and the production traits of a Chinese native

10. QTL mapping for yield components and agronomic traits in a Brazilian soybean population
Abstract The objective of this work was to map QTL for agronomic traits in a Brazilian soybean population. For this, 207 F2:3 progenies from the cross CS3035PTA276-1-5-2 x UFVS2012 were genotyped and cultivated in Viçosa-MG, using randomized block design with three replications. QTL detection was carried out by linear regression and composite interval mappi

11. Genome selection in fruit breeding: application to table grapes
ABSTRACT Genomic selection (GS) has recently been proposed as a new selection strategy which represents an innovative paradigm in crop improvement, now widely adopted in animal breeding. Genomic selection relies on phenotyping and high-density genotyping of a sufficiently large and representative sample of the target breeding population, so that the majority

12. Molecular-assisted selection for resistance to cassava mosaic disease in Manihot esculenta Crantz
The geminivirus complex known as cassava mosaic disease (CMD) is one of the most devastating viruses for cassava (Manihot esculenta Crantz). The aim of this study was to use molecular-assisted selection (MAS) to identify CMD-resistant accessions and ascertain promising crosses with elite Brazilian varieties. One thousand two hundred twenty-four accessions we
