Soybean (Glycine max) is one of the most important agricultural commodities worldwide and a major protein and oil source. Herein, we identified the soybean ubiquitin-conjugating (E2) enzyme gene (GmUBC4; Glyma.18G216000), which is significantly upregulated in response to Anticarsia gemmatalis attack and Meloidogyne incognita-induced galls during plant parasitism by plant nematode. The GmUBC4 promoter sequence and its different modules were functionally characterized in silico and in planta using transgenic Arabidopsis thaliana and G. max lines. Its full-length transcriptional regulatory region (promoter and 5´-UTR sequences, named pUceS8.3 promoter) was able to drive higher levels of uidA (?-glucuronidase) gene expression in different tissues of transgenic A. thaliana lines compared to its three shortened modules and the p35SdAMV promoter. Notably, higher ?-glucuronidase (GUS) enzymatic activity was shown in M. incognita-induced giant cells when the full pUceS8.3 promoter drove the expression of this reporter gene. Furthermore, nematode-specific dsRNA molecules were successfully overexpressed under the control of the pUceS8.3 promoter in transgenic soybean lines. The RNAi gene construct used here was designed to post-transcriptionally downregulate the previously characterized pre-mRNA splicing factor genes from Heterodera glycines and M. incognita. A total of six transgenic soybean lines containing RNAi gene construct were selected for molecular characterization after infection with M. incognita pre-parasitic second-stage (ppJ2) nematodes. A strong reduction in the egg number produced by M. incognita after parasitism was observed in those transgenic soybean lines, ranging from 71 to 92% compared to wild-type control plants. The present data demonstrated that pUceS8.3 is a gene promoter capable of effectively driving dsRNA overexpression in nematode-induced giant cells of transgenic soybean lines and can be successfully applied as an important biotechnological asset to generate transgenic crops with improved resistance to root-knot nematodes as well as other pests.

Land-use/land-cover change (LUCC) is a major cause of environmental transformation. Distant drivers, often associated with emerging markets for specific products, are now being considered one of the main factors of LUCC and are gaining attention in land change science. Consumers show an increasing interest in local and quality food, certified for its origin and its environmental production standards. A kind of agricultural product certification, Geographic Indication, identifies a product as originating from a specific region where a given quality, reputation or characteristic is attributed to its geographical origin. Sustainable land use is potentially an indirect effect of Geographic Indication, as it requires better land management in order to preserve the natural resources associated with the unique characteristics of the certified product. Located in the southern region of the state of Minas Gerais in Brazil is the region of Mantiqueira de Minas, considered one of the most important regions for the production of specialty coffees in Brazil. In 2011, the region?s tradition and reputation were recognized with a Geographic Indication, the second given for coffee regions in the country. To explore the full potential of this area for producing coffees with higher quality and meet the growing demand of this new international market, which aggregates value at specialty coffees, it became fundamental to understand the coffee environments of the region, the ?terroirs? where these coffees are obtained. Geotechnology can give a significant contribution in filling this gap. This work is part of a research project that made a detailed characterization of the region?s coffee agroecosystems. Geotechnologies were employed to map the areas occupied by coffee plantations by using RapidEye satellite images and SPRING and ArcGIS software. All the segments of the environment were characterized and mapped in detail and the relations with coffee quality were evaluated. The results showed that coffee occupies approximately 8% of the region?s total area and is mostly distributed in the hilly areas with higher elevations. They also proved that specialty coffees are more likely to be obtained in altitudes above 1100 m, also being correlated to genotype and to the post-harvest methods employed. These results provide information that allows a better understanding of the factors involved in the expression of coffee quality. They also provide the scientific basis required for obtaining a new Geographic Indication for the Mantiqueira de Minas region, this time a Denomination of Origin (DO), which will certainly aggregate value to the specialty coffees produced in this unique region.
