1. Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing t

2. Plant diversity in hedgerows amidst Atlantic Forest fragments
Hedgerows are linear structures found in agricultural landscapes that may facilitate dispersal of plants and animals and also serve as habitat. The aim of this study was to investigate the relationships among diversity and ecological traits of woody plants, hedgerow characteristics (size, age, and origin), and the structure of the surrounding Atlantic Forest

3. Interações ecológicas em Malpighiaceae no cerrado: compartilhamento de guildas de herbívoros e variações nos resultados da interação formiga-planta / Ecological interactions in Malpighiaceae in the Cerrado: sharing of guilds from herbivores and variations in the results of ant-plant interaction
Ecological interactions represent essential tools for a better understanding of natural communities, having in animal-plant relationships important models for study. For that, become needful phenological analyses of plants, capable of demonstrating the flowering strategies and with it the ways of temporal organization of resources available for herbivores. T

4. Relações planta-animal num sistema de integração lavoura-pecuária / Plant – animal relationships in an animal – crop integration system
Este trabalho buscou estudar um sistema de integração lavoura-pecuária com diferentes alturas de pastos, no período de inverno, e seus reflexos sobre a dinâmica da pastagem e o desempenho animal. O experimento foi conduzido em uma pastagem de aveia + azevém manejada sob diferentes intensidades de pastejo. O delineamento experimental foi de blocos ao ac

5. Interactions etween ants, fruits and seeds in the cerrado : the role of ants in the biology of seeds and seedlings / Interações entre formigas, frutos e sementes em solo de cerrado : o papel de formigas na biologia de sementes e plantulas
Our knowledge about seed dispersal systems has been improved considerably in the last few years. An increasing number of studies has shown that the process of plant regeneration is often much more complex than we realize, including several different agents across subsequent steps of seed dispersal. For instance, ants may reshape the seed shadow after seeds f

6. Feeding ecology of small mammals from Cerrado in southeastern Brazil / Ecologia alimentar de pequenos mamíferos de áreas de cerrado no Sudeste do Brasil
The herbivorous mammals in the Neotropics has been studied focusing on larger frugivorous species. However, small rodents and marsupials can perform the role of important selective agents by their trophic relationships. The objectives of this work were to describe the diet of some small mammals in natural remnants of Cerrado, to verify the existence of seaso

8. Receptor-like kinases from Arabidopsis form a monophyletic gene family related to animal receptor kinases
Plant receptor-like kinases (RLKs) are proteins with a predicted signal sequence, single transmembrane region, and cytoplasmic kinase domain. Receptor-like kinases belong to a large gene family with at least 610 members that represent nearly 2.5% of Arabidopsis protein coding genes. We have categorized members of this family into subfamilies based on both th

9. Grasshopper crop and midgut extract effects on plants: an example of reward feedback.
Acid extracts and a resultant fraction from solid-phase extraction (SPE) of Romalea guttata crop and midgut tissues induce sorghum (Sorghum bicolor var. Rio) coleoptile growth in 24-h incubations an average of 49% above untreated controls. When combined with plant auxin, indole-3-acetic acid (IAA), the SPE fraction shows a synergistic reaction, yielding incr

10. Acyl-homoserine lactone quorum sensing in Gram-negative bacteria: A signaling mechanism involved in associations with higher organisms
Recent advances in studies of bacterial gene expression have brought the realization that cell-to-cell communication and community behavior are critical for successful interactions with higher organisms. Species-specific cell-to-cell communication is involved in successful pathogenic or symbiotic interactions of a variety of bacteria with plant and anim

11. Comparative Analysis of SET Domain Proteins in Maize and Arabidopsis Reveals Multiple Duplications Preceding the Divergence of Monocots and Dicots1[w]
Histone proteins play a central role in chromatin packaging, and modification of histones is associated with chromatin accessibility. SET domain [Su(var)3-9, Enhancer-of-zeste, Trithorax] proteins are one class of proteins that have been implicated in regulating gene expression through histone methylation. The relationships of 22 SET domain proteins from

12. Evolutionary relationships of a plant-pathogenic mycoplasmalike organism and Acholeplasma laidlawii deduced from two ribosomal protein gene sequences.
The families within the class Mollicutes are distinguished by their morphologies, nutritional requirements, and abilities to metabolize certain compounds. Biosystematic classification of the plant-pathogenic mycoplasmalike organisms (MLOs) has been difficult because these organisms have not been cultured in vitro, and hence their nutritional requirements hav
