1. Advances observed in papaya tree propagation
Resumo O mamoeiro (Carica papaya L.) é uma fruteira de bastante interesse econômico e alimentar em todo o mundo. Sua propagação pode ocorrer tanto por via sexuada como assexuada. Tradicionalmente é propagado por sementes, entretanto, a propagação vegetativa vem sendo frequentemente utilizada com o uso de técnicas de cultura in vitro e ex vitro. Na p

3. Quality and antioxidant potential of byproducts from refining of fruit pulp
Abstract The potential use of byproducts from fruit processing has been evaluated in order to propose new uses as well as reducing costs and environmental impact. Most of the studies are focused on byproducts from primary transformation. However, byproducts from secondary transformation can reserve similar reuse opportunities. The aim of this study was to c

4. Genetic transformation of Brachiaria brizantha cv. Marandu by biolistics
ABSTRACT Brachiaria brizantha is a forage grass well adapted to tropical areas and cultivated in millions of hectares in Brazil. The apomictic mode of reproduction in this species, in addition to differences in ploidy between sexual and apomictic plants, impairs crossbreeding. The development of a methodology to transform apomictic cultivars will provide an

5. Efficient In Vitro Somatic Embryogenesis and Plant Regeneration from Mature and Immature Embryos of Wheat ( Triticum aestivum L.)
ABSTRACT An efficient regeneration system is a pre-requisite for the application of genetic transformation and functional genomics study of important plants. In this study, the effect of different factors (plant growth regulators, casein hydrolysate, aspartic acid and ascorbic acid) on in vitro embryogenesis and regeneration of Arta, Bahar and Zagros cultiva

6. 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

7. Whisker-mediated transformation of peanut with chitinase gene enhances resistance to leaf spot disease
Abstract Peanut (Arachis hypogaea) is an important legume and oilseed crop, native to South America and grown in all tropical and temperate regions of the world. A simplified and rapid direct gene delivery system in peanut was developed by vortexing silicon carbide whiskers with callus and with plasmid harboring chitinase and hygromcin genes. The effects of

8. 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

9. Flooding tolerance and cell wall alterations in maize mesocotyl during hypoxia.
This research aimed to characterize the tolerance to flooding and alterations in pectic and hemicellulose fractions from mesocotyl of maize tolerant to flooding when submitted to hypoxia. In order to characterize tolerance seeds from maize cultivars Saracura BRS-4154 and BR 107 tolerant and sensitive to low oxygen levels, respectively, were set to germinate.

10. 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

11. Análise da via de regulação gênica do miRNA156/SPL na brotação lateral e caracterização molecular do processo de emergência da gema axilar de cana de açucar / Analysis of the role(s) of the miRNA156/SPL pathway on branching/tillering and molecular characterization of sugarcane lateral bud outgrowth
Sugarcane is an economically important biofuel crop that recently has become a target for improvement of sustainable biomaterial production due to its high biomass productivity and built-in containment features. Therefore, studies aiming to improve the production of biomass per area are among the most important issues in sugarcane production. Plant biomass i

12. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality
