However, currently, less than 3% of the described Pteridophyta species have genome size estimates reported in databases, and only around one third of these are tropical species, although the tropics are home of 86% of fern diversity. The region of Timor-Leste, included in one of the 25 hotspots of biodiversity, is considered one of the richest areas of the world in terms of pteridophyte species. Nonetheless, biodiversity-driven research focused on this territory\u2019s biodiversity is scarce. This study presents novel 2C-values for 15 species of ferns collected in Timor-Leste, using flow cytometry. Furthermore, one species of the lycophyte Palhinhaea cernua (L.) Vasc. &amp; Franco, was also studied and its estimated genome size compared to a previous report. Estimates ranged from 10.45 pg in Selliguea feei Bory to 29.7 pg in Microsorum punctatum (L.) Copel, and are considered medium-size genomes. The data was compared with previous reports for closely related species. These are the first 2C-values for two families and seven genera of ferns, increasing the number of pteridophytes with reported C-values from 292 to 307.<\/jats:p>","DOI":"10.36253\/caryologia-1628","type":"journal-article","created":{"date-parts":[[2023,5,1]],"date-time":"2023-05-01T12:00:03Z","timestamp":1682942403000},"page":"109-122","source":"Crossref","is-referenced-by-count":0,"title":["Nuclear DNA 2C-values for 16 species from Timor-Leste increases taxonomical representation in tropical ferns and lycophytes"],"prefix":"10.36253","volume":"75","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6548-8535","authenticated-orcid":false,"given":"In\u00eas","family":"Sim\u00e3o","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8059-2397","authenticated-orcid":false,"given":"Hermenegildo","family":"Costa","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4673-0696","authenticated-orcid":false,"given":"Helena","family":"Oliveira","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8060-2842","authenticated-orcid":false,"given":"Helena","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Paulo","family":"Silveira","sequence":"additional","affiliation":[]}],"member":"21822","published-online":{"date-parts":[[2023,2,12]]},"container-title":["Caryologia"],"original-title":[],"link":[{"URL":"https:\/\/riviste.fupress.net\/index.php\/caryologia\/article\/download\/1628\/1396","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/riviste.fupress.net\/index.php\/caryologia\/article\/download\/1628\/1396","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,1]],"date-time":"2023-05-01T12:00:07Z","timestamp":1682942407000},"score":1,"resource":{"primary":{"URL":"https:\/\/riviste.fupress.net\/index.php\/caryologia\/article\/view\/1628"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,2,12]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2023,4,5]]}},"URL":"https:\/\/doi.org\/10.36253\/caryologia-1628","relation":{},"ISSN":["2165-5391","0008-7114"],"issn-type":[{"type":"electronic","value":"2165-5391"},{"type":"print","value":"0008-7114"}],"subject":[],"published":{"date-parts":[[2023,2,12]]}}}
