Preference of Atta capiguara (Hymenoptera, Formicidae) for Different Grasses
(Sociobiology, 2011-01-01) [Artigo]
The preference of Atta capiguara for young leaves was evaluated and developed for nine grass species. Hyparrhenia rufa, Paspalum notatum cv Comum and Andopogon gayanus were the most preferred. Paspalum notatum cv Pensacola, ...
Correlações entre caracteres silviculturais durante o crescimento de Eucalyptus grandis Hill ex Maiden
(Revista do Instituto Florestal, 2011) [Artigo]
The species Eucalyptus grandis (Hill) Maiden is the most commercial tree cultivated in Brazil and throughout the world. It is planted as varieties and also as interspecific hybrid clonal plantings. This work is a study of ...
Medicinal Mushroom Growth as Affected by Non-Axenic Casing Soil
(Pedosphere, 2011-04-01) [Artigo]
Ten different casing soils were collected from two soils at two depths (0.2 and 2.0 m below soil surface) to examine the relationships between the physical properties of non-axenic casing soil and yield, number and weight ...
Internal Architecture and Population Size of Acromyrmex subterraneus molestans (Hymenoptera, Formicidae) Nests: Comparison Between a Rural and an Urban Area
(Sociobiology, 2011-01-01) [Artigo]
Ant nests vary in their depth and internal complexity. They can be shallow or reach seven meters down into the soil, with many chambers connected by tunnels. In the case of leaf-cutting ants, the nest protects the colony ...
Seed priming improves endosperm weakening, germination, and subsequent seedling development of Solanum lycocarpum St. Hil.
(Seed Science and Technology, 2011-01-01) [Artigo]
Seed priming is a treatment to improve seed quality and plant growth upon germination and is applied widely to crop species to improve uniformity and yield. The present study aimed to establish a priming protocol for Solanum ...
Protein expression upon desiccation and imbibition of Magnolia ovata A. St.-Hil seeds
(Brazilian Archives of Biology and Technology, 2011-06-01) [Artigo]
The effect of seed drying and imbibition was studied by differential protein expression using two dimensional gel electrophoresis. After drying to a range of water contents, seeds were germinated to assess the viability. ...
The 20S proteasome alpha(5) subunit of Arabidopsis thaliana carries an RNase activity and interacts in planta with the Lettuce mosaic potyvirus HcPro protein
(Molecular Plant Pathology, 2011-02-01) [Artigo]
P>In plants, the ubiquitin/26S proteasome system (UPS) plays a central role in protein degradation and is involved in many steps of defence mechanisms, regardless of the types of pathogen targeted. In addition to its ...
