Arachis pintoi é uma leguminosa de pequeno porte, muito utilizada em consórcio com pastagem, na recuperação de áreas degradadas, conhecida pela boa associação simbiótica com bactérias fixadoras de nitrogênio. Apesar do potencial de uso dessa espécie, as informações acerca da seleção de estirpes para amendoim forrageiro adaptadas as condições edafoclimáticas da região amazônica ainda são escassas. Assim, buscou-se avaliar a eficiência simbiótica de rizóbios obtidos de diversos solos da região amazônica para Arachis pintoi cv. Amarillo em casa de vegetação após 45 dias, considerando como controle as cepas SEMIA 6439 e SEMIA 6440 recomendadas pelo Ministério da Agricultura Pecuária e Abastecimento em condições de Cerrado Brasileiro. Para tanto, este trabalho foi elucidado no artigo intitulado Eficiência simbiótica de rizóbios isolados de solos Amazônicos em Amendoim Forrageiro, apresenta resultados da caracterização morfológica, dos testes bioquímicos, bem como da produção de ácido indolacético e da eficiência simbiótica dos isolados testados. |

Understanding vulnerabilities of plant populations to climate change could help preserve their biodiversity and reveal new elite parents for future breeding programmes. To this end, landscape genomics is a useful approach for assessing putative adaptations to future climatic conditions, especially in long-lived species such as trees. We conducted a population genomics study of 207 Coffea canephora trees from seven forests along different climate gradients in Uganda. For this, we sequenced 323 candidate genes involved in key metabolic and defence pathways in coffee. Seventy-one single nucleotide polymorphisms (SNPs) were found to be significantly associated with bioclimatic variables, and were thereby considered as putatively adaptive loci. These SNPs were linked to key candidate genes, including transcription factors, like DREB-like and MYB family genes controlling plant responses to abiotic stresses, as well as other genes of organoleptic interest, such as the DXMT gene involved in caffeine biosynthesis and a putative pest repellent. These climate-associated genetic markers were used to compute genetic offsets, predicting population responses to future climatic conditions based on local climate change forecasts. Using these measures of maladaptation to future conditions, substantial levels of genetic differentiation between present and future diversity were estimated for all populations and scenarios considered. The populations from the forests Zoka and Budongo, in the northernmost zone of Uganda, appeared to have the lowest genetic offsets under all predicted climate change patterns, while populations from Kalangala and Mabira, in the Lake Victoria region, exhibited the highest genetic offsets. The potential of these findings in terms of ex situ conservation strategies are discussed.
