Peer Review #1 of "Virus-derived sequences from the transcriptomes of two snail vectors of schistosomiasis, Biomphalaria pfeifferi and Bulinus globosus from Kenya (v0.1)"

“…The majority of viruses identified from the two species of snails reported here, along with viruses identified previously from B. glabrata (Adema et al 2017;Galinier et al 2017) are similar to dicistroviruses and Marnaviruses (Fig. 2).…”

“…The RdRP sequence is highly conserved among RNA viruses (Koonin et al 1989;Zanotto et al 1996), while the viral capsid protein that functions in virus host range is more divergent. Four snail viral genome sequences (Biomphalaria glabrata virus 1, BGV1; Biomphalaria glabrata virus 2, BGV2; Biomphalaria glabrata virus 3, BGV3; and Biomphalaria virus 4, BiV4) identified from RNA sequence data for B. glabrata (Adema et al 2017;Galinier et al 2017) were included in the phylogenetic analyses. The virus names from Adema et al, were used in our analysis (based on RdRP sequences: BGV1 is BiV2 from Galinier et al,BGV2 is BiV1,and BGV3 is BiV3).…”

“…SRV+ have also been isolated from shrimp (Mari et al 2002), crabs (Boros et al 2011), bivalves (Rosani & Gerdol 2017;Rosani et al 2019) and partial sequences of virus-derived genes identified from the crop of an invasive snail (Cardoso et al 2012). Several novel SRV+ from Biomphalaria glabrata were isolated by analyzing available RNA sequence data for this Neotropical snail (Adema et al 2017;Galinier et al 2017), and analysis of the transcriptome of B. pfeifferi revealed nearly 1,300 transcripts putatively derived from viruses (Buddenborg et al 2017).…”

The genome of the golden apple snail Pomacea canaliculata provides insight into stress tolerance and invasive adaptation

“…However, research at the whole-genome level in P. canaliculata still lags far behind that in other mollusc species due to the lack of a high-quality reference genome. Multiple draft genomes of molluscs have been published, including the genomes of the California sea hare [ 37 ], Pacific oyster [ 38 ], pearl oyster [ 39, 40 ], owl limpet [ 41 ], California two-spot octopus [ 42 ], golden mussel [ 43 ], and Biomphalaria snails [ 44 ], greatly promoting research on mollusc genomics. In this study, we present a chromosome-level genome assembly of P. canaliculata with high-quality gene annotation, transcriptome data from several tissues and under various conditions, and metagenomic data from the intestinal tracts, all of which were then applied to study the species-specific environmental adaptation characteristics, such as the cellular homeostasis system underlying strong stress and the color and nutrient contents of the eggs.…”

Schistosomiasis then and now: what has changed in the last 100 years?

“…There have been significant advances in our understanding of the snail immune system, and its ability to combat schistosome infection (Mitta et al, 2017;Pila et al, 2017). Most intriguing is the possibility that miracidia may locate snail hosts by latching onto molluscan pheromone/chemoattractant systems (Adema et al, 2017;Wang et al, 2019); this could provide a mechanism with sufficient inherent specificity to explain the often tight host preference displayed by the intramolluscan stages.…”
