Comparison of protocols for genomic DNA extraction from velame pimenta (Croton linearifolius), a native species to the Caatinga, Brazil

Abstract: The Caatinga biome occupies some 12% of the Brazilian territory, which is present in at least nine states. The species that constitute its biodiversity have the potential to be used as natural resources, among them are approximately 700 species of the genus Croton. As an example of this potential, the Croton linearifolius specie is used by local communities as a natural insecticide. Associated with the economic potential of the Caatinga species, one must stress the risk of extinction or genetic erosion due to … Show more

“…Because of this great medicinal importance, genetic studies are essential to develop conservation strategies and also products (Alves et al, 2012). For Croton genus there are some research related to genetic diversity (Angelo et al, 2005;Silvestrini et al, 2015;Rinthong et al, 2011;Scaldaferri, 2013Scaldaferri, , 2014Oliveira et al, 2016;Almeida-Pereira et al, 2017;Silva et al, 2018), however, molecular information are still scarce; for species C. urucurana they are almost non-existent and it is necessary to advance in the genetic diversity characterization of this species.…”

“…These methods mainly use detergent-based extraction buffers containing cetyltrimethylammonium bromide (CTAB) [1216], sodium dodecyl sulfate (SDS) [1720] and guanidine [21]. Some methods have included in the CTAB or SDS extraction buffer, sugars such as mannitol [22] or sorbitol [23, 24], antioxidants such as PVP-40 (polyvinylpyrrolidone; molecular weight, 40,000) [3, 5, 11, 25–30], or high salt [31, 32]. Most methods use phenol/chloroform for purification of the extracted DNA; while others add a purification step, by binding the extracted DNA to glass fiber coated plate wells [33] or to an anion exchange column [34].…”

“…A seleção da técnica de extração de DNA, independente dos organismos a serem avaliados, depende da amostra estudada, do tempo necessário para a extração, suporte econômico da técnica (devido aos reagentes e equipamentos utilizados na extração) e mais importante, a qualidade do DNA extraído. Neste sentido, comumente são realizados estudos de comparação e otimização de protocolos para extração de DNA (SCALDAFERRI et al, 2013;DALBOSCO et al, 2015;VIANA et al, 2015;ZORTÉA et al, 2016). Na literatura há registro de diferentes métodos de extração de DNA que têm sido utilizados para formigas cortadeiras (DOYLE & DOYLE, 1990;WALDSCHMIDT et al, 1997).…”

“…Ao utilizar os seis protocolos de extração deste estudo, porém com a espécie de planta Croton linearifolius (Euphorbiaceae), SCALDAFERRI et al (2013) registraram o P1 como o menos eficiente e os demais protocolos como satisfatórios para a extração de DNA de C. linearifolius. Tal contraste é explicado, ao menos em parte, pelas variações entre o material biológico utilizado nesses dois estudos, sendo natural a existência de compostos secundários distintos entre tecidos de vegetais e de insetos.…”
