O USO DE CARACTERES ECOLÓGICOS E REPRODUTIVOS COMO PREDITORES PARA OS NÍVEIS DE DIVERSIDADE GENÉTICA EM PLANTAS: ABORDAGEM CIENCIOMÉTRICA E META-ANALÍTICA

Abstract

Chloroplastid markers are a class of extremely conserved gene and uniparental inheritance being of great value to better study and understand ecological and evolutionary processes acting in the populations. In addition, it provides data on several parameters, including genetic diversity (number of haplotypes, haplotype diversity, nucleotide diversity, FST). In this way, a scientific and meta-analytic approach was used to evaluate the use of chloroplastid markers in publications that obtained estimates of genetic diversity, the most studied botanical families and their species, as well as their way of life, the IUCN classification. In addition to analyzing and patterns of differentiation in plants addressing ecological and reproductive traits along with phylogenetics. The articles used were found in different databases between 1996 and March 2018. For the scientometry 612 species distributed in 134 families were registered, most of the species studied are classified as NE by the IUCN, showing a shortage of studies for species in categories (LC, NT, VU, EN, CR) with some degree of threat. The results show a growing area and a better understanding of the distribution of publications around the globe. For the meta analysis, 507 angiosperm species distributed in 118 families were registered and phylogenetics was the most influential predictor of genetic diversity.
