Provedor de dados: 100
Autores: Martínez,María A.; Duarte,Leticia; Baños,Heyker L.; Rivas,Aramis; Sánchez,Adayakni.
In order to update the presence of species of mirid predators and their impact on solanaceous crops of interest, samples were taken from tomato and tobacco in open fields and from tomato in covered crops of selected locations of Mayabeque and Las Tunas Provinces every seven days. In each sampling, mirid specimens were counted and collected for their subsequent identification and determination of incidence. The results showed the presence of the species Nesidiocoris tenuis Reuter, Macrolophus praeclarus (Distant) and Cyrtopeltis = Engyatus varians (Distant). The mirids were present in most samples taken in tomato and tobacco, while the incidence remained over 40% in both crops.

The tobacco drying greenhouses, in general, are made without any coating that ensures thermal insulation and avoid heat losses, resulting in a large consumption of firewood during the drying of the tobacco. The study aims to develop an economically viable project to the producer, to avoid excessive heat loss through the walls and ceiling of a tobacco dryer, aimed at fuel economy, reduced drying time and reduces costs in process. For the current project, we considered changes of Brazilian theoretical mode, where we developed a thermal insulation system in a dryer, reaching satisfactory results, with a large reduction in energy losses and firewood consumption, resulting in a decrease in the costs of the proceedings in general. Thus, began for the development...

The antioxidative defense system is involved in the premature senescence in transgenic tobacco (Nicotiana tabacum NC89)
Provedor de dados: 48
Autores: Liu,Yu; Wang,Lu; Liu,Heng; Zhao,Rongrong; Liu,Bin; Fu,Quanjuan; Zhang,Yuanhu.
BACKGROUND: &amp;#945;-Farnesene is a volatile sesquiterpene synthesized by the plant mevalonate (MVA) pathway through the action of &amp;#945;-farnesene synthase. The &amp;#945;-farnesene synthase 1 (MdAFS1) gene was isolated from apple peel (var. white winterpearmain), and transformed into tobacco (Nicotiana tabacum NC89). The transgenic plants had faster stem elongation during vegetative growth and earlier flowering than wild type (WT). Our studies focused on the transgenic tobacco phenotype. RESULTS: The levels of chlorophyll and soluble protein decreased and a lower seed biomass and reduced net photosynthetic rate (Pn) in transgenic plants. Reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) and superoxide radicals (O2._) had higher levels...

Biology of Corecoris dentiventris Berg, 1884 (Hemiptera, Coreidae) in tobacco culture (Nicotiana tabacum)
Provedor de dados: 57
Autores: CALDAS,B.-H. C.; REDAELLI,L. R.; DIEFENBACH,L. M. G.
Corecoris dentiventris Berg, 1884 (HEM., Coreidae) represents a pest in the tobacco culture in Southern Brazil. Nymphs and adults cause the wilting and twisting of the tobacco leaves due to their sucking habit. There are very few works about this species and these are restricted to concise description of the adult morphology, records of host plants and enumeration of injuries. The present investigation aims to study the life cycle of this bug. The experiment was carried out in a tobacco culture (Virginia type, var. K 326) implanted in the experimental area of the Departamento de Fitossanidade of the Universidade Federal do Rio Grande do Sul, in Porto Alegre, RS. The life cycle was studied in field conditions, in nylon cages, from egg clusters oviposited by...

Autores: Meneghini,A.C.; Koenigkam-Santos,M.; Pereira,M.C.; Tonidandel,P.R.; Terra-Filho,J.; Cunha,F.Q.; Menezes,M.B. de; Vianna,E.O.
Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused by tobacco smoking with COPD exclusively caused by environmental or occupational exposures. For this cross-sectional study, COPD patients were recruited from outpatient clinics and formed two groups: non-smoker COPD group (n=16) with exposure to biomass smoke who did not smoke cigarette and tobacco smoker COPD group (n=15) with people who did not report biomass smoke exposure. Subjects underwent...

Autores: Conway,S.G.; Roizenblatt,S.S.; Palombini,L.; Castro,L.S.; Bittencourt,L.R.A.; Silva,R.S.; Tufik,S.
To evaluate the effect of smoking habits on sleep, data from 1492 adults referred to the Sleep Institute were accessed and divided into 3 categories of smoking status: current, former and non-smokers. Categories of pack-years (&lt;15 and ≥15) defined smoking severity. The association of smoking status and smoking severity with sleep was analyzed for sleep parameters, especially apnea and hypopnea index (AHI) ≥5, more than 5% of total sleep time (TST) spent with oxyhemoglobin saturation (SaO2) &lt;90%, and arousal index. The arousal index was higher among current (21 ± 17) and former smokers (20 ± 17) than non-smokers (17 ± 15; P &lt; 0.04). Former smokers had a higher percent of TST at SaO2 &lt;90% than non-smokers (9 ± 18 vs 6 ± 13; P &lt; 0.04). Former...

Cloning and sequence analysis of tomato cpDNA fragments: towards developing homologous chloroplast transformation vectors
Provedor de dados: 61
Autores: Berger,Irving Joseph; Carraro,Dirce Maria; Bock,Ralph; Azevedo,Ricardo Antunes; Carrer,Helaine.
With the view of developing chloroplast transformation vectors based on homologous targeting regions for tomato (Lycopersicon esculentum L.), plastid DNA fragments of tomato cv. IAC-Santa Clara were cloned and analyzed. Isolation and cloning of PstI/SalI chloroplast fragments into the pBlueScript vectors yielded the plasmids pIJB1 and pIJB2 with cpDNA fragments of 8.6 kb and 6.4 kb, respectively. DNA sequencing and computer analyses revealed that the tomato sequences cloned display from 93 to 100 % of identity to the respective fragments in tobacco, which is more pronounced in coding regions. The intergenic spacers are somewhat less conserved suggesting that evolutionary divergences occurred mainly in these putative non-coding regions. The most remarkable...

Complementing firewood with alternative energy sources in Rio Pardo Watershed, Brazil
Provedor de dados: 65
Autores: Dessbesell,Luana; Farias,Jorge Antonio de; Roesch,Fábio.
ABSTRACT: Wood is the primary energy source for grains and Tobacco drying in the Rio Pardo Watershed (RPW). The amount of firewood produced in the RPW is not enough to supply the demand. Recently, an automatized supply system was introduced in the region enabling the use of sawdust and pellets. In this context, this study aims to compare firewood, sawdust and pellets as energy sources for Tobacco curing in air-forced curing systems. Energetic density was used to estimate the biomass consumption in Tobacco curing. The consumption of biomass is lower for pellet, followed by firewood and sawdust. Pellets and sawdust could complement firewood in the region; however, research is necessary to ascertain the economic feasibility.
