| Asian soybean rust (ASR), caused by the phytopathogenic fungi Phakopsora pachyrhizi, has caused large reductions in soybean (Glycine max) yield in most locations in Brazil where it has occurred since it was first reported in May 2001. Primary efforts to combat the disease involve the development of resistant cultivars, and four dominant major genes (Rpp1, Rpp2, Rpp3 and Rpp4) controlling resistance to ASR have been reported in the literature. To develop new long-lasting soybean ASR resistance genes, we used field experiments to assess ASR leaf lesion type in 11 soybean genotypes (BR01-18437, BRS 184, BRS 231, BRS 232, BRSGO Chapadões, DM 339, Embrapa 48, PI 200487, PI 230970, PI 459025-A and PI 200526) and the 55 F2 generations derived from their... |

| Citrus is the most important fruit crop in Brazil and Citrus tristeza virus (CTV) is considered one of the most important pathogens of citrus. Most citrus species and varieties are susceptible to CTV infection. However, Poncirus trifoliata, a close relative of citrus, is resistant to the virus. In order to better understand the responses of citrus plants to the infection of CTV, we constructed expressed sequence tag (EST) libraries with tissues collected from Poncirus trifoliata plants, inoculated or not with Citrus tristeza virus at 90 days after inoculation, grafted on Rangpur lime rootstocks. We generated 17,867 sequence tags from Poncirus trifoliata inoculated (8,926 reads) and not (8,941 reads) with a severe CTV isolate. A total of 2,782 TCs... |

| ABSTRACT: During the winter seasons of 1997 and 1998, experiments were conducted under irrigation in the experimental area of Embrapa Cerrados Research Center at Planaltina, Federal District and in the experimental area of the Piratininga Region Agricultural Cooperative (Coopertinga), Northwest of Minas Gerais State. The objective was to identify cultivars that present the following characteristics; resistance to diseases, early maturity, high yeld, resistance to lodging, desirable plant height and good market acceptance, to be indicated for cultivation in the Federal District and the Northewest of Minas Gerais State. It was concluded that the cultivar BRS Valente is indicated for these regions, due to its high yield characteristics, erect type, resistance... |
