Desarrollo floral de Acaciella angustissima (Leguminosae: Caesalpinioideae: Acacieae)
نویسندگان
چکیده
Antecedentes: Acaciella (Mill.) Britton & Rose es un género neotropical, cuyas especies se encontraban dentro del subgénero Aculeiferum (tribu Acacieae) debido a similitudes morfológicas. Estudios moleculares reflejan relaciones filogenéticas cercanas con el Calliandra Ingeae). Actualmente carece de estudios desarrollo floral para , lo cual podría proveer evidencias morfológicas relacionadas la historia evolutiva ambas tribus.
 Preguntas: ¿Los patrones angustissima serán similares reportado las tribus Acacieae e Ingeae?
 Especie estudio: Rose

Genetic diversity and mating system of Copaifera langsdorffii (Leguminosae/Caesalpinioideae).
Copaifera langsdorffii, locally known as copaíba, is a valuable tropical tree with medicinal properties of its oil. We studied the genetic variation, genetic structure, and the mating system of trees in stands of C. langsdorffii (Leguminosae/Caesalpinioideae) located in an extensive area between the Pardo and Mogi-Guaçu basins in São Paulo State, Brazil, and their offspring, conserved in an ex ...

Bacteria from nodules of the legume Acaciella angustissima native to the south of Mexico were characterized genetically and their nodulation and competitiveness were evaluated. Phylogenetic studies derived from rpoB gene sequences indicated that A. angustissima is nodulated by Sinorhizobium mexicanum, Rhizobium tropici, Mesorhizobium plurifarium and Agrobacterium tumefaciens and by bacteria rel...
متن کاملHybrid origin of "Bauhinia blakeana" (Leguminosae: Caesalpinioideae), inferred using morphological, reproductive, and molecular data.
Bauhinia blakeana (Leguminosae subfam. Caesalpinioideae tribe Cercideae), or the Hong Kong Orchid Tree, is of great horticultural value. It is completely sterile and is shown here to be the result of hybridization between the largely sympatric species, B. purpurea and B. variegata. Although the analysis of patterns of morphological variation revealed only a few examples of phenotypic intermedia...
متن کاملPatterns and development of floral asymmetry in Senna (Leguminosae, Cassiinae).
The buzz-pollinated genus Senna (Leguminosae) is outstanding for including species with monosymmetric flowers and species with diverse asymmetric, enantiomorphic (enantiostylous) flowers. To recognize patterns of homology, we dissected the floral symmetry character complex and explored corolla morphology in 60 Senna species and studied floral development of four enantiomorphic species. The asym...
متن کاملPost-zygotic reproductive isolation between sympatric taxa in the Chamaecrista desvauxii complex (Leguminosae-Caesalpinioideae).
BACKGROUND AND AIMS Differences in the mating systems and the mechanisms of reproductive isolation between Chamaecrista desvauxii var. graminea and C. desvauxii var. latistipula were examined in the Chapada Diamantina, Brazil. These taxa occur sympatrically, and their populations demonstrate marked morphological differences. The objective of the present work was to determine if reproductive iso...
