Blast disease, caused by the Magnapor the oryzae/griseaspecies complex, occurs in a wide rangeof wild and cultivated gramineous plant species including rice, wheat and barley. We inoculated a collection of cultivated (Hordeum vulgaressp.vul-gareL.) and wild (ssp.spontaneum) barley accessions with M. oryzae Oryzapathotype (MoO),Triticumpathotype (MoT) and Pennisetumpathotype (MsP) to quantify the host status of barley, and to identify sources of blast resistance. Unlike wheat, the barleygene pool is rich with sources of complete and partialresistance againstMagnaporthe. Cultivated barleyappeared a nonhost to MsP, whereas wild barleyshowed some degree of susceptibility. All 153 testedrice accessions were resistant to the MoT isolate,suggesting that rice is... |

The chemical composition of wheat kernels (Triticum aestivum L.) directly affects the quality of flour by modifying its functional and technological properties, determining its use by the industry. Field trials were conducted with wheat genotypes BRS 208 and BRS Pardela to evaluate the impact of different forms of urea (conventional, with urease inhibitor, and polymer-protected) and doses of nitrogen applied in topdressing (0, 40, 80 and 120 kg ha-1) in kernel chemical composition and flour technological quality. The experimental design was randomized block with 3x4 factorial structure, with four replications. The data were submitted to analysis of variance (ANOVA) with regression for nitrogen doses, and comparison of means for genotypes and forms of urea... |

Soil-borne wheat mosaic disease (SBWMD) caused by wheat stripe mosaic virus (WhSMV) is one of the most important viral diseases of wheat in Brazil. Farmers have used crop rotation (CR) successfully to reduce the incidence of many diseases in wheat. CR can contribute along with genetic resistance in the management of SBWMD. The objective of this study was to evaluate the effect of CR in SBWMD incidence and wheat yield as compared with wheat monoculture (W). During 2017 and 2018 growth seasons, in a long-term experiment, W and three CR: W1 ? white oats-wheat; W2 ? vetch-white oats- wheat; and W3 ? black oatsbarley-black oats-wheat were evaluated using three wheat cultivars: BRS Parrudo (resistant), BRS Reponte (moderately resistant) and BRS Guamirim... |

In this work, we examined the genetic diversity and evolution of the WAG-2 gene based on new WAG-2 alleles isolated from wheat and its relatives. Only single nucleotide polymorphisms (SNP) and no insertions and deletions (indels) were found in exon sequences of WAG-2 from different species. More SNPs and indels occurred in introns than in exons. For exons, exons+introns and introns, the nucleotide polymorphism Π decreased from diploid and tetraploid genotypes to hexaploid genotypes. This finding indicated that the diversity of WAG-2 in diploids was greater than in hexaploids because of the strong selection pressure on the latter. All dn/ds ratios were < 1.0, indicating that WAG-2 belongs to a conserved gene affected by negative selection. Thirty-nine of... |

A pesquisa sobre bactérias diazotróficas na cultura do trigo tem demonstrado a necessidade de associar bactérias eficientes a genótipos promissores, os quais se beneficiariam dessa associação. Em um experimento com parcelas subdivididas, instalado em condições de campo, em Mococa (SP), empregando os tratamentos: três doses de N (0, 60 e 120 kg ha-1) e três genótipos de trigo (IAC-24, ITD-19 e IAC-355), foi avaliada a ocorrência de microrganismos diazotróficos endofíticos em raízes desinfestadas superficialmente, utilizando-se três meios de cultivo distintos, NFb, JNFb e LGI-P. Somente para o genótipo IAC-355, houve um ajuste linear ascendente da quantidade de bactérias diazotróficas com o aumento na quantidade de N adicionada, apesar de o mesmo genótipo... |
