Intraspecific and interspecific polyploidy of Brazilian species of the genus Inga (Leguminosae: Mimosoideae)

M. F. Figueiredo, Bruno, R. L. A., Silva, A. E. Barros e, Nascimento, S., Oliveira, I. G., and Felix, L. P., Intraspecific and interspecific polyploidy of Brazilian species of the genus Inga (Leguminosae: Mimosoideae), vol. 13, pp. 3395-3403, 2014.

We investigated the karyotypes of 13 species of six sections of the genus Inga (Leguminosae-Mimosoideae) from Brazil. We used conventional Giemsa staining to identify numerical chromosomal variations and looked for karyotypic evolutionary patterns. The karyotypes generally had small chromosomes, varying from metacentric to submetacentric, with a basic number x = 13. Nine of the species showed 2n = 2x = 26 (I. thibaudiana, I. cayennensis, I. ingoides, I. edulis, I. vera, I. subnuda, I. striata, I.

Genetic diversity of Burkholderia (Proteobacteria) species from the Caatinga and Atlantic rainforest biomes in Bahia, Brazil

A. C. Santini, Santos, H. R. M., Gross, E., and Corrêa, R. X., Genetic diversity of Burkholderia (Proteobacteria) species from the Caatinga and Atlantic rainforest biomes in Bahia, Brazil, vol. 12, pp. 655-664, 2013.

The genus Burkholderia (β-Proteobacteria) currently comprises more than 60 species, including parasites, symbionts and free-living organisms. Several new species of Burkholderia have recently been described showing a great diversity of phenotypes. We examined the diversity of Burkholderia spp in environmental samples collected from Caatinga and Atlantic rainforest biomes of Bahia, Brazil. Legume nodules were collected from five locations, and 16S rDNA and recA genes of the isolated microorganisms were analyzed.
