Genetic and phenotypic association of the carnauba palm tree evaluated by inter-simple sequence repeat and biometric traits

The carnauba palm Copernicia prunifera is the third most important non-timber forest species in Brazil; it is mainly known for the production of carnauba wax. We examined intrapopulation genetic diversity and correlated genotypic and phenotypic traits of 28 trees from a coastal location in Rio Grande do Norte state. Phenotypic variables tree height, diameter at brea.. Read More»

Naturally fragmented but not genetically isolated populations of Podocarpus sellowii Klotzsch (Podocarpaceae) in southeast Brazil

    F.R. Gonçalves, F.A. Vieira and D. Carvalho

In southeastern Brazil, the majority of the riparian ecosystems are fragmented and degraded mainly due to human activities. The perennial gymnosperm Podocarpus sellowii Klotzch is a typical tree species from a gallery forest in the rupestrian area. Ten alloenzymatic loci were used to estimate the allelic frequency of 232 individuals distributed in eight subpopulatio.. Read More»

Increased relatedness among the neighboring plants from seedling to adult stages in carnaúba wax palm

    F.A. Vieira, R.F. Sousa, C.G. Fajardo and M.M. Brandão

The objective of this study was to assess the spatial genetic structure (SGS) at different life stages (cohorts) in a remnant population (N = 101) of Copernicia prunifera in the semiarid region of northeastern Brazil. Using seven inter-simple sequence repeat molecular markers, we were able to analyze 93 loci with 100% polymorphism. Seedlings had the highest level of.. Read More»

Genetic diversity of Annona crassiflora (Annonaceae) in northern Minas Gerais State

    L.G. Cota, F.A. Vieira, A.F. Melo Júnior, M.M. Brandão, K.N.O. Santana, M.L. Guedes and D.A. Oliveira

Genetic diversity analyses of tropical tree species are relevant to landscape management, plant genetic resource inventory, and biological conservation of threatened species. Annona crassiflora is an endangered fruit tree native to the Cerrado biome that is threatened by reduction of natural populations and fruit extraction. We examined the intra- and interpopulatio..

Mating system and intrapopulational genetic diversity of Copernicia prunifera (Arecaceae): a native palm from Brazilian semiarid

The aim of this study was to investigate the mating system and genetic diversity of the palm Copernicia prunifera using inter-simple sequence repeat markers. We found that the C. prunifera has multiple inflorescences with hermaphroditic flowers and pollen viability of 62%. Outcrossing rates at the population level (N = 267) produced a multilocus outcrossing rate (tm.. Read More»

Anthropization as a determinant factor in the genetic structure of Copernicia prunifera (Arecaceae)

This study uses ISSR molecular markers to characterize the demographic pattern, and spatial genetic structure (SGS) at different life stages of development (cohorts) in a natural population of Copernicia prunifera in the Rio Grande do Norte State, Brazil. All individuals were sampled and georeferenced in a 0.55-ha plot. The demographic analyses showed a clustered pa.. Read More»
