The papaya (Carica papaya) is a fruit crop of great economic importance throughout the Brazilian northeast, which is responsible for 60% of the national output. Papayas in the states of Ceará and Rio Grande do Norte are affected by lethal yellowing disease, caused by papaya lethal yellowing virus (PLYV). Previous work suggested that PLYV is a putative sobemovirus. To assess the genetic variability of PLYV, foliar samples were collected in October 2008 and October 2009 in commercial fields from Ceará and Rio Grande do Norte states, and total RNA was extracted. Specific primers based on the sequence of a previously characterized PLYV isolate were used for the RT-PCR-based amplification of a 900 bp fragment corresponding to the central region of the viral genome. Fragments from 21 viral isolates were cloned and sequenced. Sequence analyses indicated >97% nucleotide sequence identity among the isolates, 94-100% identity with the previously sequenced PLYV isolate, and a lower but significant identity with sobemoviruses (43-48.5%). These results suggest a low genetic variability among PLYV isolates, and are in agreement with the provisional placement of PLYV in the genus Sobemovirus. Definitive taxonomic conclusions, however, can only be drawn after the determination of the full-length genomic sequence. |

This study aims to evaluate the impact of two complementary public policies, one federal, Low Carbon Agriculture program (ABC), and one from Santa Catarina state, the cattle beef development program of Santa Catarina. By the official rural credit of the ABC program, the federal government aims the sustainability of beef cattle by production practices with potential mitigation of greenhouse gases (GHG). The Santa Catarina state program subsidizes federal program interest. In order to evaluate the impact of these public policies, it was evaluated 170 beef cattle farms in Santa Catarina. The evaluation consisted of visits and application of quantitative and qualitative forms. The farms were distributed in the regions of North plateau, Itajaí Valley, Mountain range, Midwest and West Santa Catarina. The evaluation period was from January 2012 to December 2016, covering the origin of the application of the resources, zootechnical indexes and economic analysis. It was found that 45% of ABC resources were used in pasture establishment and recovery, 18% in paddock subdivisions, 32% in adaptations of management centers and the remainder resources in animal genetic improvement and technical assistance. The evolution of the herd showed 21% increase in the number of animals (P=0.0016), 44% increase in the number of females (P < 0.001), and a slaughter age reduction in 12 months (P=0.0022). The relationship between the value of the projects and the value applied in pastures was positive linear (P < 0.001). There was improvement in knowledge on pasture management and on zootechnical indexes by the farmers after the five years of the programs implementation (P < 0.001). Farmers who joined the program reported unanimity regarding improvements in technical knowledge and management of the activity. It is concluded that public policies have had a positive impact in beef cattle production. Furthermore, the investment on production practices such pasture implantation and recovery, suitable pasture management, reduction on animals slaughter age presents potential to GHG mitigation.
