In order to understand the genetic responses resulting from physiological changes that occur in plants displaying citrus variegated chlorosis (CVC) symptoms, we adopted a strategy of comparing two EST libraries from sweet orange [Citrus sinensis (L.) Osbeck]. One of them was prepared with plants showing typical CVC symptoms caused by Xylella fastidiosa and the other with non-inoculated plants. We obtained 15,944 ESTs by sequencing the two cDNA libraries. Using an in silico hybridization strategy, 37 genes were found to have significant variation at the transcriptional level. Within this subset, 21 were up-regulated and 16 were down-regulated in plants with CVC. The main functional categories of the down-regulated transcripts in plants with CVC were associated with metabolism, protein modification, energy and transport facilitation. The majority of the up-regulated transcripts were associated with metabolism and defense response. Some transcripts associated with adaptation to stress conditions were up-regulated in plants with CVC and could explain why plants remain alive even under severe water and nutritional stress. Others of the up-regulated transcripts are related to defense response suggesting that sweet orange plants activate their defense machinery. The genes associated with stress response might be expressed as part of a secondary response related to physiological alterations caused by the infection. |

The Rural Collective Actions are presented with the aim of facing and overcoming difficulties and particularities of the agricultural business, as well as obtaining gains and advantages, in an environment that suffers from constant transformations. This study investigates which reasons determine the choice of the Rural Collective Action model Rural Warehouse Condominium, under the perspective of the Theory of Logic of Collective Action. For this purpose, we conducted the Statistical Analysis, Multiple Correspondence and Correlation Analysis. The results indicate motivating factors for the rural model through Social, Logistics, Political, Economic, Management and Collective Action Logic variables, being of more significant burden: (i) smaller collective actions are easier to promote collective interest; (ii) rural producers work together to promote common interests; (iii) in a small collective group, individual efforts have a higher influence on results; and, (iv) the smaller is the collective group, the closer is the individual will be to achieving collective benefits. The correlation analysis shows stronger relationships between cost reduction with freight and cost reduction with transport (0.833); and, between the lack of financing lines for small and medium producers and the lack of financing lines for agricultural warehouse (0.741). |
