| Since red alleles (R) of the genes that control grain colour are important for the improvement of preharvest sprouting resistance in wheat and there are three independently inherited loci, on chromosomes 3A, 3B and 3D of hexaploid wheat, it is possible to vary the dosage of dominant alleles in a breeding program. The objective of this work was to evaluate the dosage effect of R genes on preharvest sprouting, in a single seed descent population, named TRL, derived from the cross between Timgalen, white-grained wheat, and RL 4137, red-grained wheat. The study was carried out using sprouting data in ripe ears obtained under artificial conditions in a rainfall simulator over three years. According to the results there is a significant effect on preharvest... |

| Isolates of Salmonella sp (104) from poultry samples were isolated and serotyped where eleven were identified as Salmonella Typhimurium (ST). ST isolates were phenotypically tested by disk diffusion and minimum inhibitory concentration (MIC). Four genes related to enrofloxacin (GyrA, GyrB, ParC and ParE), two to gentamicin (AadA and AadB) and two to ceftiofur (BlaCMY-2 and AmpC) resistance were searched by PCR. Our results showed ST resistance to all three antibiotics tested (18.1% for ceftiofur, 45.4% for gentamicin, and 18.1% for enrofloxacin) according to the diffusion test. In the MIC test, the ST isolates showed higher levels of resistance (27.2% for ceftiofur, 54.5% for gentamicin, and 18.2% for enrofloxacin). Three resistance genes out of four... |

| The sixty-two of the exotic germplasms waxy corn were performed. The agronomic characters were averaged 45 - 52 days to flowerings, opaque and small kernel. Almost all plant aspects were green and less uniformity, unfortunately, downy mildew was susceptible. Three methods for S1 selection were (1) half - sib (HS) (2) full - sib (FS) and (3) S1 (S1) progeny test. Each method was received for two ears. Also, the agronomic characters were recorded, 45 - 52 days to tasseling and 46 - 52 days to silking. Economic yields, green and white weight were 588 - 1,063 and 340 - 631 kg/rai, namely, UPDW-0013 was showed the best of both. Furthermore, UPCW-0004 showed that the best shelling (71.16%). And, cutting trait was UPWC-0002 (66.67%). Afterward, 26 lines are... |

| Abstract: Background: Detection of genes evolving under positive Darwinian evolution in genome-scale data is nowadays a prevailing strategy in comparative genomics studies to identify genes potentially involved in adaptation processes. Despite the large number of studies aiming to detect and contextualize such gene sets, there is virtually no software available to perform this task in a general, automatic, large-scale and reliable manner. This certainly occurs due to the computational challenges involved in this task, such as the appropriate modeling of data under analysis, the computation time to perform several of the required steps when dealing with genome-scale data and the highly error-prone nature of the sequence and alignment data structures needed... |

| The objectives of this study were to analyze changes in gene expression and identify candidate genes and gene networks potentially inhibiting or triggering blossom-end rot (BER) in tomatoes treated with plant growth regulators. ?Ace 55 (Vf)? tomato plants were grown in a greenhouse and sprayed with Apogee (300 mg L?1), abscisic acid (ABA) (500 mg L?1), water (control), or gibberellins 4?+?7 (GA4?+?7) (300 mg L?1) weekly after pollination. The BER incidence rate was zero in Apogee- and ABA-, medium in water-, and high in GA4?+?7-treated plants from 26 to 40 days after pollination (DAP). At 26 DAP, healthy blossom-end fruit tissue still not showing visible BER symptoms was used for transcriptome analysis. Candidate genes potentially inhibiting or triggering... |

| Quantitative Real-time PCR (qRT-PCR) is a powerful technique to investigate comparative gene expression. In general, normalization of results using a highly stable housekeeping gene (HKG) as an internal control is recommended and necessary. However, there are several reports suggesting that regulation of some HKGs is affected by different conditions. The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a serious pest of corn in the United States and Europe. The expression profile of target genes related to insecticide exposure, resistance, and RNA interference has become an important experimental technique for study of western corn rootworms; however, lack of information on reliable HKGs under different... |

| Tropical soils where low phosphorus (P) and aluminum (Al) toxicity limit sorghum [Sorghum bicolor (L.) Moench] production are widespread in the developing world. We report on BRP13R, a multiparental random mating population (MPRMP), which is commonly used in sorghum recurrent selection targeting tropical soil adaptation. Recombination dissipated much of BRP13R?s likely original population structure and average linkage disequilibrium (LD) persisted up to 2.5 Mb, establishing BRP13R as a middle ground between biparental populations and sorghum association panels. Genome-wide association mapping (GWAS) identifed conserved QTL from previous studies, such as for root morphology and grain yield under low-P, and indicated the importance of dominance in the... |

| Blast, caused by the fungus Magnaporthe oryzae, is the most damaging disease in rice. The use of resistance genes in crop breeding programs has been the major, and most sustainable, means for disease control. To identify new resistance genes or alleles to be introduced in breeding lines, a mapping population was developed crossing BRS Esmeralda, an upland cultivar, and Três Marias, a Brazilian landrace internationally recognized as blast resistant. |
