Bioethanol strains of Saccharomyces cerevisiae characterised by microsatellite and stress resistance BJM
Reis,Vanda Renata; Antonangelo,Ana Teresa Burlamaqui Faraco; Bassi,Ana Paula Guarnieri; Colombi,Débora; Ceccato-Antonini,Sandra Regina.
Abstract Strains of Saccharomyces cerevisiae may display characteristics that are typical of rough-type colonies, made up of cells clustered in pseudohyphal structures and comprised of daughter buds that do not separate from the mother cell post-mitosis. These strains are known to occur frequently in fermentation tanks with significant lower ethanol yield when compared to fermentations carried out by smooth strains of S. cerevisiae that are composed of dispersed cells. In an attempt to delineate genetic and phenotypic differences underlying the two phenotypes, this study analysed 10 microsatellite loci of 22 S. cerevisiae strains as well as stress resistance towards high concentrations of ethanol and glucose, low pH and cell sedimentation rates. The...

Can WRKY transcription factors help plants to overcome environmental challenges? Genet. Mol. Biol.
Finatto,Taciane; Viana,Vívian Ebeling; Woyann,Leomar Guilherme; Busanello,Carlos; Maia,Luciano Carlos da; Oliveira,Antonio Costa de.
Abstract WRKY transcription factors (TFs) are responsible for the regulation of genes responsive to many plant growth and developmental cues, as well as to biotic and abiotic stresses. The modulation of gene expression by WRKY proteins primarily occurs by DNA binding at specific cis-regulatory elements, the W-box elements, which are short sequences located in the promoter region of certain genes. In addition, their action can occur through interaction with other TFs and the cellular transcription machinery. The current genome sequences available reveal a relatively large number of WRKY genes, reaching hundreds of copies. Recently, functional genomics studies in model plants have enabled the identification of function and mechanism of action of several WRKY...

Impact assesment of Cyclone Sally on the almost atoll of Aitutaki (cook Islands) by remote sensing ArchiMer
Loubersac, Lionel; Dahl, Arthur; Collote, Pascal; Lemaire, Olivier; D'Ozouville, Laurent.
Damage from tropical cyclones can have major consequences for coral reef structure and ecology, as well as for human communities and human uses of coral reef resources. Remote sensing with high resolution multispectral satellite images can be used to asses large scale cyclone damages on coral reef areas. SPOT images of the almost atoll of AITUTAKI (Cook Islands) taken in june 1986 and february 1987 after the passage of Cyclone Sally near the island in january, were transformed and subjected to a textural analysis, and then compared to asses damage on the reefs and lagoon.New shallow sand and rubble deposits showed increased reflectance, while lower reflectance seemed associated with damage to reef structure, scouring in the lagoon, deposits of terrestrial...

Inbreeding and building up small populations of stingless bees (Hymenoptera, Apidae) Zoologia
Nogueira-Neto,Paulo.
A study of the viability of small populations of Hymenoptera is a matter of importance to gain a better zoological, ethological, genetical and ecological knowledge of these insects, and for conservation purposes, mainly because of the consequences to the survival of colonies of many species of bees, wasps, and ants. Based on the Whiting (1943) principle, Kerr & Vencovski (1982) presented a hypothesis that states that viable populations of stingless bees (Meliponini) should have at least 40 colonies to survive. This number was later extended to 44 colonies by Kerr (1985). This would be necessary to avoid any substantial amount of homozygosis in the pair of chromosomic sexual loci, by keeping at least six different sexual gene alleles in a...

Structural static and modal frequency simulations in a coffee harvester’s chassis AGRIAMBI
Silva,Evandro P. da; Silva,Fábio M. da; Andrade,Ednilton T. de; Magalhães,Ricardo R..
ABSTRACT Coffee harvesters are subject to stresses and vibrations in their structure, originating from engines and harvesting system. These structures must be designed to avoid rupturing of the components due to fragility of the materials, inadequate geometries, or the phenomenon of resonance, which increases the displacements/deformations of the components. In this scenario, the main objective of this study is to analyse the results of stresses and displacements from two static simulations and to present results of natural vibration frequencies from two modal simulations in a self-propelled coffee harvester. For this purpose, 20 modal shapes were generated, considering coffee harvester reservoir as empty and full. The simulations were carried out using...
