Heat shock (HS) leads to the activation of molecular mechanisms, known as HS-response, that prevent damage and enhance survival under stress. Plants have a flexible and specialized network of Heat Shock Factors (HSFs), which are transcription factors that induce the expression of heat shock proteins. The present work aimed to identify and characterize the Glycine max HSF repertory in the Soybean Genome Project (GENOSOJA platform), comparing them with other legumes (Medicago truncatula and Lotus japonicus) in view of current knowledge of Arabidopsis thaliana. The HSF characterization in leguminous plants led to the identification of 25, 19 and 21 candidate ESTs in soybean, Lotus and Medicago, respectively. A search in the SuperSAGE libraries revealed 68 tags distributed in seven HSF gene types. From the total number of obtained tags, more than 70% were related to root tissues (water deficit stress libraries vs. controls), indicating their role in abiotic stress responses, since the root is the first tissue to sense and respond to abiotic stress. Moreover, as heat stress is related to the pressure of dryness, a higher HSF expression was expected at the water deficit libraries. On the other hand, expressive HSF candidates were obtained from the library inoculated with Asian Soybean Rust, inferring crosstalk among genes associated with abiotic and biotic stresses. Evolutionary relationships among sequences were consistent with different HSF classes and subclasses. Expression profiling indicated that regulation of specific genes is associated with the stage of plant development and also with stimuli from other abiotic stresses pointing to the maintenance of HSF expression at a basal level in soybean, favoring its activation under heat-stress conditions.

The variety Cabemet Sauvignon has revealed in the São Francisco Valley (9°02' S; 40°11' W) a high potential of quality, but with some limitations on its adaptation to this "terroir". The rootstocks with effective aftinity are yet unknown and the material with many virus infections makes difficult its culture, particularly in terms ofyield, which generally is very low. With the objective to maximize the behaviour ofthis variety in this terroir, a field trial was installed in Vinibrasil - Vinhos do Brasil, SA to compare the relations "variety x rootstock", with 5 clones (15, 169, 191,337 and 685) combined with 6 rootstocks (IAC-313, IAC-572, 1103-P, 420-A, 101-14 e S04). After seven harvests (two per year) consistent differences in yield were observed, mainly due to the rootstock. These disparities are due to the number of clusters and their medium weight. Autochthonous rootstocks (obtained at the Instituto Agronômico de Campinas), were those that generated the highest yield, with the IAC-313 the most productive. With regard to rootstocks commonly used in temperate climates, the 1103-P was one that showed behaviour closer to the Brazilian rootstock. The rootstocks with lower yields were generally the 101-14 Mgt and 420-A. At the qualitative level, we found only minor differences and not always in the same direction between the different rootstocks. There were no significant differences in average yield or quality among the different clones. Overall, the sensory analysis of wines produced from the clones, indicates the clones 337 and 685 as being the most agreeable, especially in the parameters of the aroma. The colour intensity is another parameter where those two clones have higher comparative values. In another way, the clone with lower colour intensity is the 191, which shows the lower content of red anthocyanins. These results show the possibility to growth C. Sauvignon in tropical semi-arid climate, with acceptable yields and high quality. On the another hand, in the establishment of new vineyards it is essential to choose the correct combination (clone x rootstock) and especially the appropriate rootstock.
