Cytoplasmic line effects for birth weight and preweaning growth traits in the Asturiana de los Valles beef cattle breed
No full textA total of 15,645 records of birth weight (BrW), weaning weight (WW) and average daily gain(ADG) from 6055 cows belonging to 2121 different dam lines were analyzed to quantify the contribution of cytoplasmic line (l) effects to phenotypic variance of preweaning growth traits in a sample of Asturiana de los Valles beef cattle breed. Only dam lines with 2 or more cows having performance records in the database were used. Bayesian estimates were obtained fitting eight different univariate and multivariate models defined depending on the inclusion or not of the permanent maternal environment (c) and the l effects. Univariate models that included
both the c and the l effects had the best fit with data (assessed by computing the logarithm of the conditional predictive ordinate; logCPO) for BrW and ADG while for WW this was the case for the model that only included the c effect. For multivariate models, the best fit with data was obtained for the model that only included the c effect (logCPO= −245,899) while the second “better” model was that which only include the l effect value(logCPO=−241,108). In general, whatever the estimation model used, estimates of heritability for the direct (h2) and maternal (m2) genetic effects and the genetic correlation between them (ram) obtained in the current study for BrW were slightly higher (ram more negative)than the most recent estimates reported in the breed. However, this is not true for WW and
ADG when multivariate estimation models include the l effect. In these cases, estimates of h2 and m2 forWWand ADG tend to be lower and ram less negative than those previously estimated.
In conclusion, the cytoplasmic line may have a marginal effect on growth performance in
beef cattle but not sufficient in magnitude to justify including the l effect in models in beef improvement schemes
Introgression and pyramiding into common bean market class fabada of genes conferring resistance to anthracnose and potyvirus
No full textAnthracnose and bean common mosaic (BCM) are considered major diseases in common bean crop causing severe yield losses worldwide. This work describes the introgression and pyramiding of genes conferring genetic resistance to BCM and anthracnose local races into line A25, a bean genotype classified as market class fabada. Resistant plants were selected using resistance tests or combining resistance tests and marker-assisted selection. Lines A252, A321, A493, Sanilac BC6-Are, and BRB130 were used as resistance sources. Resistance genes to anthracnose (Co-2 ( C ), Co-2 ( A252 ) and Co-3/9) and/or BCM (I and bc-3) were introgressed in line A25 through six parallel backcrossing programs, and six breeding lines showing a fabada seed phenotype were obtained after six backcross generations: line A1258 from A252; A1231 from A321; A1220 from A493; A1183 and A1878 from Sanilac BC6-Are; and line A2418 from BRB130. Pyramiding of different genes were developed using the pedigree method from a single cross between lines obtained in the introgression step: line A1699 (derived from cross A1258 × A1220), A2438 (A1220 × A1183), A2806 (A1878 × A2418), and A3308 (A1699 × A2806). A characterization based on eight morpho-agronomic traits revealed a limited differentiation among the obtained breeding lines and the recurrent line A25. However, using a set of seven molecular markers linked to the loci used in the breeding programs it was possible to differentiate the 11 fabada lines. Considering the genetic control of the resistance in resistant donor lines, the observed segregations in the last backcrossing generation, the reaction against the pathogens, and the expression of the molecular markers it was also possible to infer the genotype conferring resistance in the ten fabada breeding lines obtained. As a result of these breeding programs, genetic resistance to three anthracnose races controlled by genes included in clusters Co-2 and Co-3/9, and genetic resistance to BCM controlled by genotype I + bc-3 was combined in the fabada line A3308

«Nuestro puesto está en el hogar.» Los campamentos femeninos en Asturias durante el primer franquismo (1938-1945)
Get PDFOne of the most popular and advertised initiatives aimed at young people and children during the Francoist period were the summer camps. They tried to build an ideal society there, with no social classes or nationalisms and with a perfect performance of the gender roles imposed by the Francoist authorities. In this paper I will focus on
the ofcial speech and activities addressed to female children and young women in these summer camps, which were specially designed to familiarise them with their future social roles: motherhood and housekeeping. To do so, I will use as an example the ones located in Asturias between 1938 and 1945.Una de las iniciativas más populares y anunciadas destinadas a las juventudes durante el Franquismo fueron los campamentos y albergues de verano. En ellos se trataba de construir una sociedad ideal y armónica a pequeña escala, sin clases ni nacionalismos periféricos y en la que funcionaran perfectamente los roles de género impuestos por el Estado franquista. En este artículo me centraré en analizar el discurso o cial y las actividades dirigidas a las niñas y jóvenes en estos campamentos, que estaban especialmente concebidos para orientarlas hacia su destino social: la maternidad y el cuidado del hogar. Para ello tomaré como ejemplo los organizados en Asturias entre 1938 y 1945. Las fuentes utilizadas son fundamentalmente hemerográ cas, provenientes de los diarios falangistas asturianos La Nueva España y Voluntad, aunque también haré referencia a algunos documentos del Fondo de la Delegación Provincial de la Sección Femenina conservados en el Archivo Histórico de Asturias
Screening of enzymatic activities in non-Saccharomyces cider yeasts
Get PDFThe activities of polygalacturonase, pectin lyase, b-glucosidase, b-xylosidase and protease were determined using solid media in 420 wild non-Saccharomyces cider
strains identified by internal transcribed spacer-restriction fragment length polymorphism.
The identified species corresponded to Hanseniaspora valbyensis, Hanseniaspora
uvarum, Hanseniaspora osmophila, Metschnikowia pulcherrima, Candida
parapsilosis and Pichia guilliermondii. The most common activity exhibited was that of b-glucosidase (33%), with all the analyzed species having some strains able to develop this activity. Strains of M. pulcherrima showed the greatest capacity to produce b-glucosidase and protease. b-xylosidase was detected in 17 yeast strains belonging to the genera Hanseniaspora, Pichia and Metschnikowia. All of the tested species have some strains with the capacity to develop b-xylosidase activity, except for C. parapsilosis. No strains were able to secrete pectin lyase, while polygalacturonase activity was observed in eightHanseniaspora strains. Only two strains, belonging to the species H. uvarum and M. pulcherrima, developed three enzymatic activities, namely b-glucosidase, b-xylosidase and protease

No evidence that wild red deer (Cervus elaphus) on the Iberian Peninsula are a reservoir of Mycobacterium avium subspecies paratuberculosis infection
No full textThe potential role of red deer (Cervus elaphus) as a reservoir of Mycobacterium avium subspecies paratuberculosis (MAP) infection is largely unknown. A total of 332 wild red deer were investigated using post-mortem examination, bacteriology and serology. Only three animals (1.12%) were found to have lesions on histopathological examination and no MAP bacteria were recovered on culture. The results suggest it is unlikely that wild red deer make a significant contribution to the maintenance of MAP infection in the region. The cross-reactivity of the ELISAs used indicates this diagnostic modality is ineffective in the detection of MAP infection in this species. The implications of these results for the control of this important pathogen in both livestock and wildlife are discussed
