RESUMO - A estrutura genética da raça Hampshire de pedigree do Brasil foi analisada por meio de registros do Pig Book Brasileiro, pelo método de amostragem. O número de granjas passou de oito, em 1973, para 17 em 1980, totalizando 42 no citado período, com 3.548 registros emitidos. Para as granjas existentes neste período, a duração média de atividade de registro foi de 3,10 anos e o tamanho médio dos planteis 1,5 macho e 6,5 fêmeas. Os rebanhos que apresentaram maior contribuição de machos para a raça foram: o grupo de progenitores importados e as granjas Seara, SC, Raquel, SC, Emboque, PR e Cruzeiro do Sul, PR. O macho importado de PBB 1053 e o brasileiro de PBB 247 foram os de maior relacionamento direto com a raça (10,2%), seguindo por ordem os machos PBB 1557 (9%) e PBB 1740 (8,6%). As fêmeas com maior relacionamento foram a PBB 1555 (6,7%) importada e a PBB 1369 (6,7%), brasileira. A consanguinidade total acumulada ate 1980 foi de 3,13% correspondendo a um incremento de 0,81% por geração. O índice de subdivisão de raça foi de 0,33 meses, sendo as idades médias dos machos e fêmeas, quando do nascimento de suas progênies, 27,6 e 31,2 meses, respectivamente. A reposição média de machos do próprio plantel, considerando todas as granjas, foi de 66,7%. Foram classificadas como Elite 33,33%, como Multiplicadoras 22,22% e como Mistas 44,45%, do total de nove granjas incluídas na amostra. ABSTRACT - The breed structure of the pedigree Hampshire in Brazil was analysed from records of the Brazilian Pig Book, and by the pedigree samplinq method. The number of herds for the 1973 to 1980 period was 42, changing from eight in the first year to 17 in the last year. The total number of records was 3,548 for eight years. During the period, the average existence of the herds in the Pig Book was 3.10 years and the herd average size was 1.5 boars and 6.5 sows. The most important herds, accordíng to their genetic contribution for the breed were: the group of imported progenitors, plus the herds Seara, SC, Raquel, SC, Emboque, PR and Cruzeiro do Sul, PR. The imported boar PBB 1053 and the brazilian boar PBB 247 presented the largest direct relationship to the breed (10.2%), followed by the boars PBB 1551(9%) and PBB 1740 (8.6%).The sows with largest relationship were the imported PBB 1555 (6.7%) and the brazilian PBB 1369 (6.1%). The total inbreeding up to 1980 was 3.13%, corresponding to an increasing of 0,81% por generation. The strains breed subdivision index was 0.33, meaning the inexistence of a natural strain formation, within the breed. The average generation length was 29,4 months and the averege age of the males and females, when the progeny was bom, corresponded to 21.6 e 31.2 months, respectively. The average replacement rate of boars from the own herd, considering all the farms, was 66.7%. The 33.33% of the farms were classified as Elite, the 22.22% as Multiplier and the 44.45% as mixed, from a total of nine farms in the sample.

Our goal is to acquire critical molecular data on the Asian soybean rust (ASR) infection process in susceptible and resistant soybean cultivars. To define specific molecular events in the soybean plant that are associated with ASR resistance and susceptibility, we detected gene expression over a 7-day time course in both ASR- and mock-infectecd leaves from susceptible and resistant (Rpp2) cultivars by using Affymetrix Soybean GeneChip microarrays. Statistical analysis showed that l ,516 and 894 genes in the susceptible and resistant cultivars, respectively, significantly changed expression. Most genes were differentially expressed within the first 3 days after infection (dai), followed by a 2-day time period in which very few genes were differentially exprcssed. After 4 dai, host gene expression diverged again between mock- and ASR-infected leaves. Arabidopsis homologs were identified for 1,302 and 773 differentially regulated genes in the susceptible and resistant cultivars, respectively, which allowed us to perform functional classification. These analyses revealed that genes with functions in metabolism and disease/defense were statistically overrepresented in both the susceptible and resistant cultivars gene lists. ASR-regulated genes involved in signal transduction and energy generation were overrepresented in the susceptible cultivar, while genes with functions in transport and transcription were overrepresented in the resistant cultivar. ASR-regulated genes involved in post-transcriptional regulation or with no known function were underrepresented in both cultivar?, and genes involved in cell structure, growth and development, and protein synthesis appeared to be underrepresented in the resistant cultivar.
