Molecular diversity of fungal and bacterial communities in the marine sponge Dragmacidon reticulatum

Abstract: The present work aimed to investigate the diversity of bacteria and filamentous fungi of southern Atlantic Ocean marine sponge Dragmacidon reticulatum using cultivation-independent approaches. Fungal ITS rDNA and 18S gene analyses (DGGE and direct sequencing approaches) showed the presence of representatives of three order (Polyporales, Malasseziales, and Agaricales) from the phylum Basidiomycota and seven orders belonging to the phylum Ascomycota (Arthoniales, Capnodiales, Dothideales, Eurotiales, Hypocreales… Show more

“…However, one quantitative statement that can be made for the seven sponge studied here is that with the exception of P. ficiformis the number of fungal reads was very low in comparison to the number of sponge reads (2550 reads vs. 330,884 reads). This is in line with the low relative abundance of fungi in nineteen other sponge species that were assessed by cultivation-independent methods (Gao et al 2008;He et al 2014;Passarini et al 2015;Rodríguez-Marconi et al 2015;Wang et al 2014). The low number of fungal reads also corraborates the lack of microscopic observation of fungi reported from sponge tissues.…”

“…The state of the art is that we currently know very little about fungi from sponges. Based on the data shown here and other cultivationindependent studies targeting sponge-associated fungi (Gao et al 2008;He et al 2014;Passarini et al 2015;Rodríguez-Marconi et al 2015) there are indications that we know very little because there is little to be known. The combination of low numbers of fungal reads retrieved from sponges with their unspecific nature based on the currently available data point towards merely accidental presence of fungi in sponges.…”

“…The strain MUT 4775 was identified as Coprinellus radians and MUT 2331 as Psathyrella candolleana. The species C. radians is not new to the marine environment and was found in association with the marine sponge Dragmacidon reticulatum (Passarini et al, 2015) and with the zoanthid Palythoa haddoni (Qin et al, 2015). Species of Psathyrella occur mainly in terrestrial habitats, even though the ability to occupy uncommon niches is not rare for this genus (e.g.…”
