Solving the mystery of Obake rice in Africa: Population structure analyses of Oryza longistaminata reveal three genetic groups and evidence of both recent and ancient introgression... por Labroo, Marlee R., Clark, Lindsay V., Zhang, Shilai, Hu, Fengyi, Tao, Dayun, Hamilton, Ruaraidh Sackville, Sacks, Erik J.

“…To facilitate the conservation, management, and use of O. longistaminata germplasm, we sought to quantify the population structure and diversity of this species across its geographic range, which includes most of sub-Saharan Africa, and to determine phylogenetic relationships to other AA-genome species of rice present in Africa, including the prevalence of interspecific hybridization between O. longistaminata and O. sativa. …”

Characterization of hemizygous deletions in Citrus using array-Comparative Genomic Hybridization and microsynteny comparisons with the poplar genome por Ríos, Gabino, Naranjo, Miguel A., Iglesias, Domingo J., Ruiz-Rivero, Omar, Geraud, Marion, Usach, Antonio, Talón, Manuel

“…The study of gene content and order into the 39B3 deletion also led to the unexpected conclusion that microsynteny and local gene colinearity in this species were higher with Populus trichocarpa than with the phylogenetically closer Arabidopsis thaliana. This work corroborates the potential of Citrus genomic resources to assist mutagenesis-based approaches for functional genetics, structural studies and comparative genomics, and hence to facilitate citrus variety improvement.…”

Nodulation of the N2-fixing legume narrow-leafed lupin (Lupinus angustifolius L.) por Gregorc, Martin

“…Sequences of a part of the 16S-23S internal transcribed spacer showed that the nitrogen fixing rhizobium of both soils had highest identity to Bradyrhizobium sp in the B. japonicum group. However, a phylogenetic analysis showed good separation of the two clusters formed by the rhizobia of the two soils suggesting that the Bradyrhizobium sp in the Skåne agricultural soils is genetically different from that in the Uppsala perennial lupin soil. …”
