The Brazilian Northeastern dry forest (Caatinga) is one of the diversification centers of Mimosa species. We determined the characteristics of native rhizobia isolates from nodules of Mimosa tenuiflora and Mimosa paraibana grown in pots with soils collected under Caatinga vegetation and compared the restriction ribosomal DNA profiles of the isolates with those of 16 reference strains. All plants formed abundant indeterminate nodules and all nodule isolates formed fast growing colonies. No colony altered the medium to an alkaline reaction and most of them produced low or medium amounts of extracellular polysaccharides. White and creamy colonies predominated among the isolates but orange and green colonies were present. Differences among the isolates from the Mimosa species tested are indicated by the greater phenotypic diversity of those obtained from M. tenuiflora. The analysis of the 16S rDNA gene suggests that the isolates from M. tenuiflora and M. paraibana are closely related and closer to B-rhizobia than to α-rhizobia. However, the similarity with all the tested B-rhizobia reference strains was relatively low suggesting that the isolates may belong to different bacteria species. |

Canchim is a synthetic beef cattle developed in Brazil which have good growth potential and tropical adaptation but suboptimal fat deposition. There are genomic regions associated with fat deposition already described, among them the centromeric region of BTA14. The scope of this work was to identify genomic regions associated with backfat thickness in Canchim (5/8 Charolais + 3/8 zebu) and MA (offspring of Charolais bulls and 1/2 Canchim + 1/2 Zebu cows) populations and to validate the association of haplotypes of the BTA14 with backfat thickness in this population. Thirty animals with extreme phenotypes were genotyped with the 54 K SNP chip, revealing 100 signifi cant SNPs contained in chromosomes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 17, 18, 19, 20, 21, 23, 24, 27, 28 and X. Thirty-four SNPs constituted seven chromosomal regions containing 3 or more SNPs located at intervals shorter than 9 Mb and, among these, ten SNPs in BTA 14 were selected for validation. Genotyping in the population was performed by the TaqMan method in families comprising more than 10 individuals with backfat thickness information at the age of 18 months (644 animals). Validation of the BTA14 SNPs revealed two haplotypes, one in the centromeric region and another in the middle region of BTA14, signifi cantly associated with fat thickness, both with additive effects on backfat thickness. Genes located close to these two regions should be further studied to identify potential mutations involved in backfat deposition.
