1. Cuerpos y espacio en un mito de origen alternativo
Abstract: The present article explores Doris Lessing's novel The Cleft (2007) by means of conceptualizations of space and the body that highlight their instability and ever-changing qualities, resulting from their socially constructed nature. The Cleft revisits the myth of origin of humankind through the interpretation of ancient manuscripts that a Roman Sen

2. Interspecific hybrids between Paspalum plicatulum and P. oteroi: a key tool for forage breeding
ABSTRACT Grama-tio-pedro (Paspalum oteroi Swallen) is a rare stoloniferous grass of the Plicatula group of Paspalum, well adapted to continuous grazing in areas subject to seasonal flooding in the Pantanal region, in central western Brazil. The species is a facultative apomictic (asexual reproduction by seed) tetraploid, sporadically cultivated on Pantanal f

3. Mating type loci analysis indicates that Villosiclava virens, the casual agent of false smut disease of rice, is a homothallic fungus
Villosiclava virens (anamorph: Ustilaginoidea virens) was isolated from infected rice plants, where it caused false smut. Similar to other ascomycetes, the sexual compatibility of V. virens is controlled by the mating type (MAT) locus. In this study, we applied a PCR-based approach to screen mating type genes in the single asexual spore isolate. Our results

4. Self-sterility in the hexaploid Handroanthus serratifolius (Bignoniaceae), the national flower of Brazil
Polyploidization is common among angiosperms and might induce typically allogamous plants to become autogamous (self-compatible, relying on sexual self-fertilization) or apomictic (achieving asexual reproduction through seeds). This work aimed to determine whether neopolyploidy leads to the breakdown of the self-incompatibility system in the hexaploid non-ap

5. Aspectos morfofisiológicos na clonagem de Eucalyptus benthamii / Morphophysiological aspects in the cloning of Eucalyptus benthamii
Dentre as poucas espécies de Eucalyptus que apresentam aptidão ao cultivo em regiões de baixas temperaturas e a geadas frequentes, destacam-se genótipos de Eucalyptus benthamii que representam opções para futuros plantios florestais em diferentes regiões brasileiras. Porém, existem poucas informações quanto a obtenção de mudas clonais, e se focar

6. Mixed reproduction systems in Opuntia monacantha (Cactaceae) in Southern Brazil
The Cactaceae have morphological and physiological adaptations associated with their life histories that are reflected in different modes of reproduction and multiplication. The reproductive phenology, preferential reproductive mode, and the sexual and asexual multiplication of Opuntia monacantha were investigated between 2003 and 2006 in two restinga (sandy

7. A anêmona-do-mar Diadumene Stephenson, 1920: um cnidário com potencial invasor na Baía de Paranaguá, PR, Brasil / The sea anemone Diadumene Stephenson, 1920: a cnidarian with an invasion potential in Paranaguá Bay, PR, Brazil
A great number of sea anemones of the genus Diadumene Stephenson, 1920 were found fixated on natural and artificial substrates at the Paranaguá Bay. In 1989, in a study conducted at the same location, the number of anemones of this genus, not identified to a specific level, was much lower. The great abundance of anemones that has currently been observed may
