1. Respuesta de Trigos con la presencia de translocación 2NS/2AS, Rmg8 y Rmg7 a Pyricularia oryzae patotipo Triticum de Paraguay.
RESUMO Poucas fontes de resistência do trigo à Pyricualria oryzae B.C. Couch and L.M. Kohn em trigo são conhecidas, estando a principal ligada a uma translocação do segmento 2NS/2AS de Aegilops ventricosa, seguida por outros genes como Rmg8 e Rmg7 localizados nos cromossomas 2B (trigo hexaplóide) e 2A (trigo tetraplóide), respectivamente. É igualment

2. Rapid Detection of ACTG- and AK-Toxins in Alternaria alternata by LC-ESI-MS/MS Analysis and Antifungal Properties of Citrus Compounds
A methanol-soluble fraction of the dichloromethane extract from the culture broth of A. alternata AT4303 strain afforded the following five known mycotoxins: alternariol, alternariol monomethyl ether, altenusin, altenuene and altertoxin I. A hexane-soluble fraction of the dichloromethane extract yielded the steroids ergosterol and ergosterol peroxide, and al

3. Inheritance patterns and identification of microsatellite markers linked to the rice blast resistance in BC2F1 population of rice breeding
The BC2F1 population was derived from a cross between rice variety, MR219 (susceptible to blast) and Pongsu Seribu 1 (resistant to blast). The objectives of this research were to know the inheritance pattern of blast resistance and to identify the linked markers associated with blast resistance in BC2F1 population. Sixteen microsatellite markers were found a

4. Sweet orange scab with a new scab disease "syndrome" of citrus in the USA associated with Elsinoë australis
Elsinoë fawcettii causes citrus scab and E. australis causes sweet orange scab and there are different pathotypes of each species. Citrus scab is widely distributed, whereas sweet orange scab is limited mostly to southern South America. In 2010, E. australis was detected by PCR in Texas for the first time in the USA and subsequently found in commercial area

5. Characterization of type and genetic diversity among soybean cyst nematode differentiators
The development of soybean cyst nematode, Heterodera glycines Ichinohe, resistant genotypes with high yields has been one of the objectives of soybean (Glycine max (L.) Merrill) breeding programs. The objective of this study was to characterize the pathotype of soybean cyst nematodes and analyze the genetic diversity of ten differentiator lines ('Lee 74', Pe

6. Análise da interação entre citros e alternaria alternata patótipo tangerina / Analysis of the interaction between citrus and Altermaria alternata tangerine pathotype
O patótipo tangerina do fungo Alternaria alternata produz a toxina hospedeiro específica ACT que afeta tangerinas e seus híbridos e causa a doença conhecida como mancha marrom de alternaria (MMA). A toxina ACT causa necrose em plantas susceptíveis, afetando ramos, folhas novas e frutos. Os sintomas incluem pontos marrons a negros circundados por um halo

7. Hot spots for diversity of Magnaporthe oryzae physiological races in irrigated rice fields in Brazil.
Abstract ? The objective of this work was to evaluate the Magnaporthe oryzae pathotype diversity in new commercial irrigated rice fields in the Araguaia River Valley, state of Tocantins, Brazil. The causal agent of rice blast has heavily affected rice production in the region. Despite the efforts of breeding programs, blast resistance breakdown has been reco

8. Performance of the black bean "BRS Valente" in Brazil.
BRS Valente was derived from a triple cross among Emgopa 201-Ouro/Onix/An 512586, and conducted in bulk from F1 to F3. From F4 to F6 the populations were inoculated with Colletotrichum lindemuthianum pathotype 89 (alfa Brasil), and the susceptible plants were eliminated. BRS Valente possesses desirabele grain appearance (size, from and 100 grain weight) and

9. Genetic diversity and virulence pattern in field populations of Pyricularia grisea from rice cultivar Metica-1.
Rice blast is a major yield constraint of the irrigated rice in the State of Tocantins, Brazil. The objective of this investigation was to study the phenotypic and genetic diversity within the pathogen population of Pyricularia grisea in samples collected from four individual farms of rice cultivar Metica-1, under epidemic conditions of leaf blast. A set of

10. Resistance spectra of six elite breeding lines of upland rice to Pyricularia grisea.
The objective of this work was to evaluate the resistance spectra of six elite breeding lines of rice, developed for improved yield and grain quality, in inoculation tests in the greenhouse and in the field. Forty-six isolates of Pyricularia grisea collected from the cultivar Primavera, 31 from the cultivar Maravilha and 19 from six elite breeding lines, tot

11. Infectious bronchitis in Brazilian chickens: current data and observations of field service personnel
The infectious bronchitis virus (IBV) was detected for the first time in Brazil by Hipólito in 1957 in chickens sold life in the municipal market of Belo Horizonte, MG, when commercial poultry production was just starting in that country. The Massachusetts (Mass) serotype was identified. However, the clinical disease was only observed in 1975, when poultry

12. Caracterização de prováveis genes do sistema de secreção tipo III em Escherichia coli de adesão difusa
The diffusely adhering Escherichia coli (DAEC) is a heterogeneous group and less characterized when compared to other pathotypes of E. coli. The fact that some strains are pathogenic and others not, creates doubts about the exact classification of this group. Contributes to it, the lack of molecular markers corresponding to the virulence genes of DAEC. Some
