Association mapping of drought tolerance indices in wheat: QTL-rich regions on chromosome 4A Scientia Agricola
Ballesta,Paulina; Mora,Freddy; Del Pozo,Alejandro.
ABSTRACT Drought is likely the main abiotic stress that affects wheat yield. The identification of drought-tolerant genotypes represents an effective way of dealing with the continuous decrease in water resources as well as the increase in world population. The aim of this study was to identify single nucleotide polymorphisms (SNP) associated with drought tolerance indices in wheat by using a genome-wide association study (GWAS) under fully irrigated and rain-fed conditions. The drought tolerance indices (i.e., Stress Susceptibility Index, Stress Tolerance Index, Tolerance Index and Yield Stability Index) were calculated based on grain yield, 1,000-kernel weight and kernels per spike. The association panel was genotyped using genotyping-by-sequencing...

Candidate genes for male and female reproductive traits in Canchim beef cattle. Repositório Alice
BUZANSKAS, M. E.; GROSSI, D. do A.; VENTURA, R. V.; SCHENKEL, F. S.; CHUD, T. C. S.; STAFUZZA, N. B.; ROLA, L. D.; MEIRELLES, S. L. C.; MOKRY, F. B.; MUDADU, M. de A.; HIGA, R. H.; SILVA, M. V. G. B.; ALENCAR, M. M. de; REGITANO, L. C. de A.; MUNARI, D. P..
Background: Beef cattle breeding programs in Brazil have placed greater emphasis on the genomic study of reproductive traits of males and females due to their economic importance. In this study, genome-wide associations were assessed for scrotal circumference at 210 d of age, scrotal circumference at 420 d of age, age at first calving, and age at second calving, in Canchim beef cattle. Data quality control was conducted resulting in 672,778 SNPs and 392 animals. Results: Associated SNPs were observed for scrotal circumference at 420 d of age (435 SNPs), followed by scrotal circumference at 210 d of age (12 SNPs), age at first calving (six SNPs), and age at second calving (four SNPs). We investigated whether significant SNPs were within genic or surrounding...

Genome-wide association for growth traits in Canchim beef cattle. Repositório Alice
BUZANSKAS, M. E.; GROSSI, D. A.; VENTURA, R. V.; SCHENKEL, F. S.; SARGOLZAEI, M.; MEIRELLES, S. L. C.; MOKRY, F. B.; HIGA, R. H.; MUDADU, M. A.; SILVA, M. V. G. B.; NICIURA, S. C. M.; TORRES JÚNIOR, R. A. de A.; ALENCAR, M. M.; REGITANO, L. C. A.; MUNARI, D. P..
Abstract. Studies are being conducted on the applicability of genomic data to improve the accuracy of the selection process in livestock, and genome-wide association studies (GWAS) provide valuable information to enhance the understanding on the genetics of complex traits. The aim of this study was to identify genomic regions and genes that play roles in birth weight (BW), weaning weight adjusted for 210 days of age (WW), and long-yearling weight adjusted for 420 days of age (LYW) in Canchim cattle. GWAS were performed by means of the Generalized Quasi-Likelihood Score (GQLS) method using genotypes from the BovineHD BeadChip and estimated breeding values for BW, WW, and LYW. Data consisted of 285 animals from the Canchim breed and 114 from the MA genetic...

Abstract The D-genome progenitor of wheat (Triticum aestivum), Aegilops tauschii, possesses numerous genes for resistance to abiotic stresses, including drought. Therefore, information on the genetic architecture of A. tauschii can aid the development of drought-resistant wheat varieties. Here, we evaluated 13 traits in 373 A. tauschii accessions grown under normal and polyethylene glycol-simulated drought stress conditions and performed a genome-wide association study using 7,185 single nucleotide polymorphism (SNP) markers. We identified 208 and 28 SNPs associated with all traits using the general linear model and mixed linear model, respectively, while both models detected 25 significant SNPs with genome-wide distribution. Public database searches...

Root anatomical traits, which include cortical area, aerenchyma area, and xylem features, influence the absorption and translocation of water and nutrients, oxygen transport and the mechanical strength of the root system. While a number of studies have shown promising functional benefits of anatomical root traits in conferring resource acquisition efficiency, very little is known about the genetic mechanisms underlying natural phenotypic variation of these traits. In this study, we evaluated 336 Oryza sativa accessions selected from the rice diversity panel for 4 root anatomical traits including, root cross-section area, aerenchyma, and xylem features in well-controlled greenhouse environment. Considerable phenotypic variation was observed in all root...
