A global review of chromosome number and genome size for the filmy ferns family (Hymenophyllaceae, Polypodiopsida)

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

Hymenophyllaceae compreende um grupo de samambaias com cerca de 450 espécies organizadas em nove gêneros. Nessa família, o tamanho de genoma e número cromossômico têm sido explorados em estudos taxonômicos e evolutivos. Contudo, não existe atualmente uma compilação desses dados. Assim, o objetivo deste trabalho foi compilar dados sobre o número cromossômico e tamanho do genoma para Hymenophyllaceae. Foi construído um panorama destacando os padrões encontrados nos gêneros e subgêneros. Também discutimos as áreas geográficas amostradas e questões metodológicas que permeiam a aquisição de dados. A pesquisa incluiu o número cromossômico e tamanho de genoma para 158 e 15 espécies, respectivamente. Essas características apresentaram uma grande variação, o número cromossômico variou de 2n = 22 a 356 e o tamanho do genoma variou de 2C = 21,47 pg a 73,2 pg. Nos gêneros Callistopteris, Polyphlebium, Vandenboschia, Crepidomanes e Hymenophyllum o valor mais frequente foi 2n = 72 e múltiplos deste, já em Trichomanes e Cephalomanes as espécies apresentaram principalmente 2n = 64 (ou múltiplos), e em Didymoglossum a maioria tem 2n = 68 (ou múltiplos). Por fim, esperamos que esta revisão possa auxiliar no desenvolvimento de pesquisas futuras, proporcionando o melhor entendimento da evolução e taxonomia da família.
