ABSTRACT: The efficiency of maize transformation mediated by Agrobacterium tumefaciens is influenced by various factors. The aim of this study was to test the effect of different concentrations of N6 salts (50% ? half strength, and 100% - full strength) in the infection and cocultivation media on genetic transformation efficiency of the L3 tropical elite maize line. Immature embryos were transformed via A. tumefaciens harboring the binary vector pTF102 containing the genes uidA and BAR under control of the CaMV35S promoter. The efficiency of the transgenic events produced was 3% for full strength and 1.1% for half strength N6 salts. Although under a lower concentration of salts, GUS expression was stronger; under this concentration, regeneration was less efficient. Thus, the results showed that the presence of 100% N6 salts in the infection and cocultivation media favored genetic transformation of the L3 maize inbred line mediated by A. tumefaciens. |

MODIS (Moderate Resolution Imaging Spectroradiometer) data provide coverage of large areas and high periodicity. These characteristics are fundamental for monitoring strategic agricultural crops in Brazil, such as sugarcane. Data mining is a promising approach to enhance remote sensing data analysis. The objective of this work was to apply the decision tree induction technique to classify sugarcane crop in São Paulo, Brazil, by using MODIS data. A classification model with a good accuracy has been obtained. Furthermore, such an induction technique allowed for knowledge discovery through decision rules that are relevant for specialists. The results revealed the adherence of data mining techniques to satellite image classification problems. |
