The tonoplast intrinsic aquaporin (TIP) subfamily of Eucalyptus grandis: Characterization of EgTIP2, a root-specific and osmotic stress-responsive gene

Aquaporins have important roles in various physiological processes in plants, including growth, development and adaptation to stress. In this study, a gene encoding a root-specific tonoplast intrinsic aquaporin (TIP) from Eucalyptus grandis (named EgTIP2) was investigated. The root-specific expression of EgTIP2 was validated over a panel of five eucalyptus organ/tissues. In eucalyptus roots, EgTIP2 expression was significantly induced by osmotic stress imposed by PEG treatment. Histochemical analysis of transgenic tobacco lines (Nicotiana tabacum SR1) harboring an EgTIP2 promoter:GUS reporter cassette revealed major GUS staining in the vasculature and in root tips. Consistent with its osmotic-stress inducible expression in eucalyptus, EgTIP2 promoter activity was up-regulated by mannitol treatment, but was down-regulated by abscisic acid. Taken together, these results suggest that EgTIP2 might be involved in eucalyptus response to drought. Additional searches in the eucalyptus genome revealed the presence of four additional putative TIP coding genes, which could be individually assigned to the classical TIP1-5 groups. © 2013 Elsevier B.V.

Cartografia temática do atlas de sensibilidade ambiental a derramamentos de óleo do litoral paulista

The objective of this paper is the elaboration and implementation of procedures in a cartographic representation related by fundamental of thematic cartography and graphic semiology for the standardization of the Environmental Oil Spill Sensitivity Maps supported by a Geographic Information Systems (GIS) for handling and modeling of a large number of variables. These make up the Environmental Sensitivity Atlas to Oil Spills in Coastal Paulista, and that represents the phenomena that occur in geographic space accurately so as to highlight the importance of each element in the evaluation and protection of areas of greater sensitivity oil. The composition of the cartographic documents considers the Littoral Sensitivity Index (LSI), biological resources and the resources for human use that could be negatively impacted. Thus, the information contained in each map was carefully evaluated before implementation, so that the cartographic representations of various resources, environments, and other ISLs, the reader should issue an immediate message that could be understood clearly, without requiring prior knowledge of specialized. Another aspect was the distribution harmoniously all the elements contained in the document, so that information could be enough without overwhelming it. It was also taken a certain care, so each symbol could be used properly in order that there is no conflict in the information.
