Development and characterization of microsatellite loci for Tabebuia cassinoides (Bignoniaceae)

V. Q. Pretti, Françoso, E., Sforça, D. A., Pinheiro, F., Meyer, D., and Lohmann, L. G., Development and characterization of microsatellite loci for Tabebuia cassinoides (Bignoniaceae), vol. 13, pp. 5601-5605, 2014.

Tabebuia cassinoides (Lam.) DC., popularly known as caxeta, is a tree species that belongs to the plant family Bignoniaceae. This species is endemic to the Brazilian Atlantic Forest and is widely exploited commercially. To date, little is known about its genetic structure, preventing the establishment of adequate management plans for this taxon. The objective of this study was to construct a microsatellite-enriched genomic library for T. cassinoides to select polymorphic loci, and standardize polymerase chain reaction amplification conditions.

Genetic diversity of natural populations of Anemopaegma arvense (Bignoniaceae) in the Cerrado of São Paulo State, Brazil

A. P. Batistini, Telles, M. P. C., Bertoni, B. W., J. Coppede, daS., Môro, F. V., S. França, deC., and Pereira, A. M. S., Genetic diversity of natural populations of Anemopaegma arvense (Bignoniaceae) in the Cerrado of São Paulo State, Brazil, vol. 8, pp. 52-63, 2009.

Catuaba (Anemopaegma arvense), a Bignoniaceae species endemic to Cerrado regions, shows anticancer properties and is widely used as a stimulant in traditional medicine. We evaluated the genetic diversity of seven populations found in the State of São Paulo, using random amplified polymorphic DNA markers. After optimization of the amplification reaction, 10 selected primers produced 70 reproducible bands, with 72.8% polymorphism. The greatest genetic diversity was observed within populations (71.72%).
