13. Effect of biologically treated petroleum sludge on seed germination and seedling growth of Vigna unguiculata (L.) Walp. (Fabaceae)
The present investigation was carried out to study the response of different concentrations of treated petroleum sludge on seed germination, root and shoot length and tolerance of Vigna unguiculata (L.) Walp. The biologically treated petroleum sludge with bacterial consortium showed 54.8% reduction in total petroleum hydrocarbons. Treated sludge was utilized

14. Evaluation of stress tolerance and fermentative behavior of indigenous Saccharomyces cerevisiae
Sixty six indigenous Saccharomyces cerevisiae strains were evaluated in stressful conditions (temperature, osmolarity, sulphite and ethanol tolerance) and also ability to flocculate. Eighteen strains showed tolerant characteristics to these stressful conditions, growing at 42 ºC, in 0.04% sulphite, 1 mol L-1 NaCl and 12% ethanol. No flocculent characteristi

15. Cloning of Ammopiptanthus mongolicus C-repeat-binding factor gene and its cold-induced tolerance in transgenic tobacco
C-repeat-binding factors (CBFs) are a type of important regulon in stress-related signal transduction pathways that control plant tolerance of abiotic stress. Ammopiptanthus mongolicus is the only evergreen broadleaf shrub in the northwest desert of China. The species shows strong resistance to environmental stress, especially to cold stress. An A. mongolicu

16. O papel modulador do receptor símile a TOLL 2 (TLR2) e da microbiota intestinal na sensibilidade e sinalização da insulina em camundongos / The modulatory role of the Toll-like receptor (TLR)2 and of the gut microbiota in the modulation of the insulin sensitivity and signaling
Environmental factors and host genetics interact to control the gut microbiota, which may have a role in the development of obesity and insulin resistance. TLR2 deficient mice, under germ-free conditions are protected from diet-induced insulin resistance. Diet-induced obese mice, acutely treated with TLR2 oligonucleotide antisense during 4 days showed increa

17. In silico identification of known osmotic stress responsive genes from Arabidopsis in soybean and Medicago
Plants experience various environmental stresses, but tolerance to these adverse conditions is a very complex phenomenon. The present research aimed to evaluate a set of genes involved in osmotic response, comparing soybean and medicago with the well-described Arabidopsis thaliana model plant. Based on 103 Arabidopsis proteins from 27 categories of osmotic s

18. Respostas fisiológicas a dessecação e a re-hidratação em quatro espécies de pteridófitas epifíticas
Epiphytic plants are more sensible to environmental variations than terrestrial plants, especially in relation to water availability. The water then stands out as one of the most important limiting factors. However, some species have evolved the ability to tolerate desiccation, showing a significant adaptive advantage in the occupation of habitats. The aim o

19. Biochemical and physiological responses of sugarcane cultivars to soil water deficiencies
For sugarcane (Saccharum spp.) crops, the effects of an environmental stress, especially water deficiency, may cause severe productivity reduction, inferring negatively in the sugarcane industry. The tolerance of two sugarcane cultivars to a lack of water was made by analyzing the levels of the osmoprotectors, trehalose and free proline, and the biometrical

21. Bioactive compounds and antioxidant capacities in the flavedo tissue of two citrus cultivars under low temperature
Antioxidants production is amongst the physiological responses of plants to protect their tissues from oxidative damages caused by chilling and freezing stresses. Indeed, cold tolerance of plants is related to production of reactive oxygen species (ROS) scavengers to combat oxidative stress. In this study, two citrus cultivars including Citrus sinensis 'Siav

22. CaracterizaÃÃo fenotÃpica de rizÃbios de solo rizosfÃrico de leguminosas nativas do semi-Ãrido cearense / Phenotypic characterization of rhizobia soil rhizosphere of legumes native to semi-arid region of CearÃ
Os diferentes solos e manejos culturais afetam o equilÃbrio entre solo e organismos endÃgenos, os quais, por sua vez afetam a sustentabilidade do solo. Desse modo acredita-se que a diversidade dos organismos do solo tenha uma relaÃÃo estreita com a diversidade de outros organismos, tanto na superfÃcie, quanto no prÃprio solo e que as interaÃÃes dessa

23. Análises moleculares das vias de sinalização de morte celular originadas no retículo endoplasmático / Molecular analyses of cell death pathways signalling originated in the endoplasmic reticulum
Abiotic and biotic stresses are responsible for major losses in agricultural productivity world wise. Therefore, the understanding of mechanisms of plant stress response and adaptation to such conditions should provide the foundation for engineering plant stress tolerance and hence maximizing the yield of crops growing under adverse environmental conditions.

24. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima
