Abstract: By plotting physical environmental maps in GIS against the geographical location of germplasm collections it is possible to infer environmental characteristics of the very collection sites. Such accrued information may reveal to be usefui in further processes of collecting, characterization, conservation and use for plant genetic resources. Cenargen has been particularly active with this line of research since1996. A pilot study was carried out in 1997 with 11 species of Manihot in this regard. Geographical information from 286 specific collection sites were plotted against the following maps (scale 1:5.000.000) by making use of GIS technology: Major Biomes, Relief Units and Agroecological Zoning (the latter including data on vegetation forms, fertility, texture and drainage of soils). Despite the modest resolution of the maps, the resulting information confirmed in general lines the field records made by the collectors. These maps, in addition to the Northeast Agroecological Zoning map (scale 1:2.000.000), were used in 1998 towards the development of the Brazilian Cassava Core Collection. Ecogeography was a main criterium used to stratify the 4.100 accessions of the Brazilian Germplasm Collection of Cassava. This was possible through the use of those maps in GIS applied to the 5 ecoregional areas of the country holding regional Active Germplasm Banks. The use of environmental maps in GIS, despite the low degree of such maps stands out as an useful ancillary tool in the efforts to characterize and conserve plant genetic resources kept in large germplasm collections.

Tonoplast intrinsic proteins (TIPs) are a subfamily of aquaporins, belonging to the major intrinsic protein family. In a previous study, we have shown that a citrus TIP isoform, CsTIP2;1, is highly expressed in leaves and also transcriptionally regulated in leaves and roots by salt and drought stresses and infection by ?Candidatus Liberibacter asiaticus?, the causal agent of the Huanglongbing disease, suggesting its involvement in the regulation of the flow of water and nutrients required during both normal growth and stress conditions. Here, we show that the overexpression of CsTIP2;1 in transgenic tobacco increases plant growth under optimal and water- and salt-stress conditions and also significantly improves the leaf water and oxidative status, photosynthetic capacity, transpiration rate and water use efficiency of plants subjected to a progressive soil drying. These results correlated with the enhanced mesophyll cell expansion, midrib aquiferous parenchyma abundance, H2O2 detoxification and stomatal conductance observed in the transgenic plants. Taken together, our results indicate that CsTIP2;1 plays an active role in regulating the water and oxidative status required for plant growth and adaptation to stressful environmental conditions and may be potentially useful for engineering stress tolerance in citrus and other crop plants. |
