Over-expression of CYP78A98, a cytochrome P450 gene from Jatropha curcas L, increases seed size of transgenic tobacco

Electron. j. biotechnol; 19 (1), 2016
Background: Jatropha curcas L. (further referred to as Jatropha), as a rapidly emerging biofuel crop, has attracted worldwide interest. However, Jatropha is still an undomesticated plant, the true potential of this shrub has not yet been fully realized. To explore the potential of Jatropha, breeding and ...

The effects of ethylene on the HCl-extractability of trace elements during soybean seed germination

Electron. j. biotechnol; 18 (5), 2015
Background Ethylene is capable of promoting seed germination in some plant species. Mobilization of metals such as Fe, Cu, Mn, and Zn in mature seeds takes place when seeds are germinating. However, whether ethylene is involved in the regulation of soybean seed germination and metal element mobilization ...

Avaliação dos compostos bioativos presentes na semente de Passiflora spp. e sua influência sobre marcadores bioquímicos, oxidativos e inflamatórios de camundongos submetidos à dieta hiperlipídica

O consumo de dieta hiperlipídica e consequente acúmulo de lipídios nos adipócitos é uma condição associada ao estresse oxidativo e à perpetuação de um quadro inflamatório de leve intensidade que leva ao desenvolvimento de doenças crônicas não transmissíveis. Uma vez que alguns componentes ...

Association between biometric characteristics of tomato seeds and seedling growth and development

Electron. j. biotechnol; 18 (4), 2015
Background The size and weight of tomato seeds depend on genetics and can be modified by environment and management. In some species, a strong relation has been described between physical aspects of the seeds and the quality of the corresponding seedlings, but this cannot be considered a general rule. Th...

Enriquecimiento diferencial de Pseudomonas spp. en el rizoplano de distintas especies cultivadas
Selective enrichment of Pseudomonas spp. in the rhizoplane of different plant species

Rev. argent. microbiol; 47 (2), 2015
En contraste con la simbiosis entre rizobios y leguminosas, la especificidad de las Pseudomonas en la colonización radicular parece menos estricta. Sin embargo, estudios sobre la diversidad bacteriana del nicho rizosférico resaltan la influencia de la especie vegetal en la selección específica de cie...

Inhibitory effect of lotus seedpod oligomeric procyanidins on advanced glycation end product formation in a lactose-lysine model system

Electron. j. biotechnol; 18 (2), 2015
Background Industrial food processing induces protein glycation modifications and toxic advanced glycation end products (AGEs) which affect human health. Therefore, it is of interest to monitor AGEs in food processing. The present study was carried out to investigate the influence of lotus seedpod oligom...

Hidrolisado proteico da semente de cupuaçu como fonte de peptídeos inibidores da enzima conversora da angiotensina I

Peptídeos com ação inibitória da enzima conversora da angiotensina I (ECA) podem ser obtidos a partir de diversos alimentos e exercer efeito anti-hipertensivo. O cupuaçu (Theobroma grandiflorum S.), fruto nativo da Amazônia, possui sementes comestíveis contendo proteína de reserva similar à do c...

Pleiotropic effects of the sdw1 locus in barley populations representing different rounds of recombination

Electron. j. biotechnol; 17 (5), 2014
Background In the present study populations, representing different rounds of recombination were used for the analysis of phenotypic effects associated with the sdw1/denso locus. Other studies have mostly focused only on one type of population. Many different QTLs mapped at the same position as the sdw1/...

Amassamento durante o manejo do cultivo: efeito no rendimento e na qualidade de sementes de soja

Biosci. j. (Online); 30 (4), 2014
Com o objetivo de avaliar a produção e a qualidade fisiológica de sementes de soja produzidas em diferentes linhas amassadas pelo rodado do trator durante as aplicações de agrotóxicos, foi realizado um experimento no município de Jari – RS, durante a safra 2008/2009. Foi determinada a altura das...

Segregation distortion in homozygous lines obtained via anther culture and maize doubled haploid methods in comparison to single seed descent in wheat (Triticum aestivum L. )

Electron. j. biotechnol; 17 (1), 2014
Background The quality of wheat grain depends on several characteristics, among which the composition of high molecular weight glutenin subunits, encoded by Glu-1 loci, are the most important. Application of biotechnological tools to accelerate the attainment of homozygous lines may influence the proport...
