The soybean-Bradyrhizobium symbiosis can be highly efficient in fixing nitrogen, but few genomic sequences of elite inoculant strains are available. Here we contribute with information on the genomes of two commercial strains that are broadly applied to soybean crops in the tropics. B. japonicum CPAC 15 (=SEMIA 5079) is outstanding in its saprophytic capacity and competitiveness, whereas B. diazoefficiens CPAC 7 (=SEMIA 5080) is known for its high efficiency in fixing nitrogen. Both are well adapted to tropical soils. The genomes of CPAC 15 and CPAC 7 were compared to each other and also to those of B. japonicum USDA 6T and B. diazoefficiens USDA 110T. Differences in genome size were found between species, with B. japonicum having larger genomes than B. diazoefficiens. Although most of the four genomes were syntenic, genome rearrangements within and between species were observed, including events in the symbiosis island. In addition to the symbiotic region, several genomic islands were identified. Altogether, these features must confer high genomic plasticity that might explain adaptation and differences in symbiotic performance. It was not possible to attribute known functions to half of the predicted genes. About 10% of the genomes was composed of exclusive genes of each strain, but up to 98% of them were of unknown function or coded for mobile genetic elements. In CPAC 15, more genes were associated with secondary metabolites, nutrient transport, iron-acquisition and IAA metabolism, potentially correlated with higher saprophytic capacity and competitiveness than seen with CPAC 7. In CPAC 7, more genes were related to the metabolism of amino acids and hydrogen uptake, potentially correlated with higher efficiency of nitrogen fixation than seen with CPAC 15. Several differences and similarities detected between the two elite soybean-inoculant strains and between the two species of Bradyrhizobium provide new insights into adaptation to tropical soils, efficiency of N2 fixation, nodulation and competitiveness.

AbstractResin tapping is an activity that aims to extract resin from trees, and thususe this product industrially. The species most used for resin tapping in Brazil is Pinus elliottiivar, elliottii. The extracted resin is basically composed of rosin and turpentine, which are used by thechemical industry. Although the main resin processes currently used are well known, new systems must be tested, such as the closed system and new compositions of stimulating pastes. These new processes and the new compositions of stimulatingpastes can make the resintappingeven more efficient and profitable. Therefore, our goal was to evaluate the effect on resin production withdifferentcompositions of stimulant pastes in resin extraction, in a closed "borehole" resin system,at differentcollection times, intrees from a population of 10-year-old Pinus elliottiivar. elliottiiplanted in Itapetininga, São Paulo. According to results, the effect of stimulating paste 4 (30% jasmonate, 4% naturoil and water) and paste 6 (30% jasmonate, 4% adhesive spreader and water) was evident in the highest production average resin per tree. Resin tappingin a closed process can be a good alternative for producers to better control the resin production system. The development of the chemical industry thatuses products derivedfrom resin and the growth of different markets, with considerable social, economic and environmental impacts, depends on future research and generation of technology for the production of resin and its derivatives. ResumoA resinagem é uma atividade que visa extrair a resina de árvores, e assim utilizar esse produto industrialmente. A espécie mais utilizada para resinagem no Brasil é o Pinus elliottiivar.elliottii. A resinaextraída é composta basicamente por breu e terebintina que são utilizados pela indústria química. Apesar de serem bem conhecidos os principais processos de resinagem utilizados atualmente, novos sistemas devem ser testados, como por exemplo, o sistema fechado e novascomposição de pastas estimulantes. Esses processos novos e a novas composições das pastas estimuladoras podem tornar a atividade da resinagem cada vez mais eficiente e rentável. Sendo assim, objetivamosavaliar o efeito na produção de resina comnovas composição de pastas estimulantes na extração de resina,em um sistema fechado de resinagem ?borehole?,em diferentes épocas de coleta, em árvores de uma população de Pinus elliottiivar. elliottiide 10 anos de idade plantadas em Itapetininga,SãoPaulo. De acordo com os resultados observados, ficou evidenciado o efeito da pasta estimuladora 4 (30% de jasmonato, 4% de naturóleo e água) e a pasta 6 (30% de jasmonato, 4% de espalhante adesivo e água), na maior produção média de resina por árvore.A produção de resina emum processo fechado pode ser uma boa alternativa para os produtores controlarem melhor o sistema produtivo de resina. O desenvolvimento da indústria química que utilizada produtos derivados da resina e o crescimento de diferentes mercados, com osconsideráveis impactos sociais, econômicos e ambientais, depende de futuras pesquisas e geração de tecnologia para produção de resina e seus derivados. ResumenLa resinación es una actividad que tiene como objetivo extraer resina de losárboles, y así utilizar industrialmente este producto. La especie más utilizada para resinas en Brasil es Pinus elliottiivar. elliottii. La resina extraída está compuesta básicamente porcolofonia y trementina,que son utilizados por la industria química. Aunque los principales procesos de resinas utilizados actualmente son bien conocidos, se deben ensayar nuevos sistemas, como el sistema cerrado y nuevas composiciones de pastas estimulantes.Estos nuevos procesos y las nuevas composiciones de las pastas estimulantes pueden hacer que la actividad resinera sea aún más eficiente y rentable. Por lo tanto, nuestro objetivo fue evaluar el efecto sobre la producción de resina con nuevas composiciones de pastas estimulantes en la extracción de resina, en un sistema cerrado de resina "borehole", en diferentes tiempos de recolección, en árboles de una población de Pinus elliottii var. elliottii de 10 años plantada en Itapetininga, São Paulo. De acuerdocon los resultados observados, el efecto de la pasta estimulante 4 (30% jasmonato, 4% aceite natural y agua) y la pasta 6 (30% jasmonato, 4% esparcidor de adhesivo y agua) se evidenció en la mayor producción promedio de resina por árbol. La producciónderesina en unprocesocerrado puede ser una buena alternativa para que los productores controlen mejor el sistema de producción de resina.
