1. MUDANÇAS ESTRUTURAIS E ESPACIAIS NA AGRICULTURA
Resumo De uma região onde até finais do século XIX apenas a pecuária despontava como atividade de maior rentabilidade, a porção sul do Estado de Goiás se transformou em um dos principais centros do agronegócio nacional. Além da pecuária, destaca-se a produção de soja, milho, cana-de-açúcar e a avicultura. Essa transformação envolveu diferente

2. Establishment of an Embryonic Tip Regeneration System of Soybean
ABSTRACT In order to establish an optimal soybean embryonic tip regeneration system that can serve as soybean genetic transformation receptor, and be used for the study of genetic function verification, the influences of single factor on the adventitious bud of embryonic tip induction, elongation and rooting stage, are researched and compared.The single fact

3. Impact of particle size, thermal processing, fat inclusion, and moisture addition on starch gelatinization of broiler feeds
The present study evaluated the effect of feed particle size, thermal processing different levels of fat inclusion and of moisture addition on the amount of gelatinized starch in a corn-soybean broiler diet. The different processing factors were combined in a 2 x 4 x 4 x 2 factorial arrangement in a three randomized block design consisting of three productio

4. Bivalent RNA interference to increase isoflavone biosynthesis in soybean (Glycine max)
In this work, a bivalent RNA interference (RNAi) plant-transformation vector was constructed to silence both the flavanone 3-hydroxylase (F3H) gene and the flavone synthase II (GmFNSII) gene in soybean (Glycine max). Two further unit RNAi vectors were constructed for each of these two genes. RNAi-mediated suppression of these genes effectively regulated flav

5. Introduction of the rd29A: AtDREB2A CA gene into soybean (Glycine max L. Merril) and its molecular characterization in leaves and roots during dehydration
The loss of soybean yield to Brazilian producers because of a water deficit in the 2011-2012 season was 12.9%. To reduce such losses, molecular biology techniques, including plant transformation, can be used to insert genes of interest into conventional soybean cultivars to produce lines that are more tolerant to drought. The abscisic acid (ABA)-independent

6. Indução do promotor GmNAC6 por elicitores de estresses e mapeamento de regiões reguladoras / Induction of the promoter GmNAC6 by elicitors of stress and mapping of regulatory regions
NAC domain-containing proteins are unique to plants and comprise a large gene family of transcriptional factors implicated in diverse aspects of plant development and stress responses. The GmNAC6 was recently identified as a downstream component of the ER (endoplasmic reticulum) stress- and osmotic stress-induced NRP (N-rich proteins)-mediated cell death sig

7. Soybean genetic transformation: a valuable tool for the functional study of genes and the production of agronomically improved plants
Transgenic plants represent an invaluable tool for molecular, genetic, biochemical and physiological studies by gene overexpression or silencing, transposon-based mutagenesis, protein sub-cellular localization and/or promoter characterization as well as a breakthrough for breeding programs, allowing the production of novel and genetically diverse genotypes.

8. Identificação e caracterização de genes codificantes de proteínas ricas em glicina ligantes de RNA em soja (Glycine max (L.) Merril)
Molecular information on plant developmental process, as well as detailed knowledge of the interaction between stress conditions and plant response to environmental factors are essential for understanding the adaptive response. Glycine-Rich Proteins (GRP) have the amino acid glycine well represented in their primary structure. The genes encoding GRPs are dev

9. Soybean cultivar BR-16-AHAS tolerance to the herbicide imazapyr.
The objective of this work was to evaluate the effect of the transgenic soybean BR-16-AHAS genetic constitution on the tolerance to the herbicide imazapyr. BR-16-AHAS was crossed with ten other genotypes. The experimental design was a complete randomized block, in a 2x12x3 factorial arrangement, with two sowing periods (winter and summer), twelve crossing gr

10. Padronização de metodologias de regeneração, via embriogênese somática e organogênese, e de aclimatização de soja (Glycine max (L.) Merrill) / Methodology standardization for regeneration via somatic embryogenesis and organogenesis and for acclimatization of soybean (Glycine max (L.) Merrill)
Different methodologies for in vitro regeneration have already been developed for several soybean cultivars. However, this species has proven to be recalcitrant to tissue culture and its in vitro morphogenetic response has been considered genotype dependent. Taking into account the need to develop reliable protocols for regeneration and acclimatization in so

11. Resistance to Anticarsia gemmatalis Hübner (Lepidoptera, Noctuidae) in transgenic soybean (Glycine max (L.) Merrill Fabales, Fabaceae) cultivar IAS5 expressing a modified Cry1Ac endotoxin
Somatic embryos of the commercial soybean (Glycine max) cultivar IAS5 were co-transformed using particle bombardment with a synthetic form of the Bacillus thuringiensis delta-endotoxin crystal protein gene cry1Ac, the beta-glucuronidase reporter gene gusA and the hygromycin resistance gene hpt. Hygromycin-resistant tissues were proliferated individually to g
