Tbe rep gene of Bean golden mosaic virus (BGMV) is essential for virus replication, and rep gene rnutations with amino acid codons cbanges in the putative NTP-binding rnotif D262R (MI) was created. Phaseolus vulgaris rransforrnation was achieved with a helium driven particle acceleration device. Tbe vector contained the bar gene [resistance to arnmonium glyphosinate (AG)] and besides the rep gene mutant. A total of J 7 initial - R(O) - transformants were analyzed. From the R(O) plant M1/4, which had mutation MI, six progeny plants with resistance to AG were obtained, and four remained BGMV symptomless after inoculation. From tbese four plants, a total progeny of 127 R(2) plants were inoculated. Of the 35 progenies of plant M 1/4/l, only three plants showed syrnptoms. From the other 92 plants, 72 had symptoms. Two plants out of 20 in the nontransgenic control plants remained symptornless. |

The production and emission of CO2 in native, pasture and cultivated areas is a result of microbiological activity and mineralization of organic matter, and depends on favorable environmental factors, such as temperature, availability of water and of land use. The results of this work show that the no tillage system (NT) has the potential to mitigate 37.7% of C-CO2 efflux from cultivation of soy compared to conventional tillage (CT). The temperature of the soil accounted for 65% of the variability of the flux of CO2-C in CT. The variation of soil moisture explained 73 and 51% of the flux of CO2-C in CT and NT, respectively. These results indicate that soil moisture and soil temperature were controlling factors of CO2-C emissions from soil to atmosphere because these parameters directly affect soil microbial activity. The results also show that the active pasture had the highest outflows of soil CO2-C to the atmosphere in relation to forests and degraded pasture in Western Pará. Furthermore, it was shown that both the pastures and forests have seasonality in the fluw, which mainly related to precipitation patterns and water potential between soil and air. We observed a strong correlation between the efflux and soil moisture of both capoeira and in the pastures, as the soil temperature was a controlling factor of the active efflux only in the pasture. The average fluw of CO2-C obtained in pasture active was 218.9 mg C m-2 h-1 value of 40.7% higher than the primary forests and 155.5 mg C m-2 h-1. Finally, the results presented here suggest that the conventional tillage and pasture management are activities strongly associated to human enhance biogeochemical changes in the balance of carbon in these ecosystems, since the efflux of CO2-C is related to soil primary productivity of these ecosystems.
