“…The study of 'wood-eating' in Parhyale can offer new insights into lignocellulose digestion in the absence of gut microbes, and the unique opportunity to apply molecular genetic approaches to understand the activity of glycosyl hydrolases in the digestive system. Lignocellulose digestion may also have implications for gut immunity in some crustaceans, since these reactions have been reported to take place in a sterile gut (Boyle and Mitchell, 1978; Zimmer et al, 2002). …”

“…Apart from attracting research interest as an economically important food crop, this group of animals has been used to study developmental biology and the evolution of morphological diversity (for example with respect to Hox genes) (Martin et al, 2015; Averof and Patel, 1997; Liubicich et al, 2009; Pavlopoulos et al, 2009), stem cell biology (Konstantinides and Averof, 2014; Benton et al, 2014), innate immunity processes (Vazquez et al, 2009; Hauton, 2012) and recently the cellular mechanisms of regeneration (Konstantinides and Averof, 2014; Benton et al, 2014; Alwes et al, 2016). In addition, members of the Malacostraca, specifically both Amphipods and Isopods, are thought to be capable of 'wood eating' or lignocellulose digestion and to have microbiota-free digestive systems (King et al, 2010; Kern et al, 2013; Boyle and Mitchell, 1978; Zimmer et al, 2002). …”

The amphipod crustacean Parhyale hawaiensis is a blossoming model system for studies of developmental mechanisms and more recently regeneration. We have sequenced the genome allowing annotation of all key signaling pathways, transcription factors, and non-coding RNAs that will enhance ongoing functional studies. Parhyale is a member of the Malacostraca clade, which includes crustacean food crop species. We analysed the immunity related genes of Parhyale as an important comparative system for these species, where immunity related aquaculture problems have increased as farming has intensified. We also find that Parhyale and other species within Multicrustacea contain the enzyme sets necessary to perform lignocellulose digestion ('wood eating'), suggesting this ability may predate the diversification of this lineage. Our data provide an essential resource for further development of Parhyale as an experimental model. The first malacostracan genome will underpin ongoing comparative work in food crop species and research investigating lignocellulose as an energy source.DOI: http://dx.doi.org/10.7554/eLife.20062.001

“…The ability of these species to assimilate such material appears to be affected by the nature and variety of digestive enzymes. The ability to digest cellulose was already demonstrated in some marine isopods (Zimmer et al 2002). But as for the parent species Idotea wosnesenskii, this ability is weakly developed.…”

“…But as for the parent species Idotea wosnesenskii, this ability is weakly developed. Moreover, the use of hepatopancreatic endosymbionts that contribute to cellulose digestion appears absent in marine isopods (Zimmer et al 2002).…”

“…Other two idoteids reach in general a mean of 75 individuals per m 2 for I. hectica (Dimech et al 2006) and between 3 and 5 individuals per kilogram dry weight of P. oceanica litter for C. prismatica (Gallmetzer et al 2005). To make coexistence possible and reduce competition, co-occurring detritivores usually differ in terms of feeding apparatus morphology, feeding strategies, nutritional requirements or digestive capabilities (Arsuffi and Suberkropp 1989;Graça et al 1993;Zimmer et al 2002;Zimmer and Bartholmé 2003). Hence, the coexistence of these species in the same biotope raised the question about trophic diversity in this particular environment.…”

Trophic diversity of idoteids (Crustacea, Isopoda) inhabiting the Posidonia oceanica litter

The coexistence of three idoteid species in Posidonia oceanica litter raises the question of trophic diversity and their role in the litter degradation process. Hence, diet composition of Idotea balthica, Idotea hectica and Cleantis prismatica was studied using a combination of gut contents and stable isotopes analysis. Gut content observations indicate that P. oceanica dead leaves are an important part of the ingested food for the three species, although their tissues are constituted of only a small to medium fraction of P. oceanica carbon. Our results also underlined the potential role of these species in the degradation of P. oceanica litter by mechanically fragmenting the litter and by assimilating a small to medium fraction of carbon. Moreover, we showed that there were considerable inter-and intra-specific differences in diet composition. Diet differed between juveniles and adults for I. balthica. Crustaceans are an important food source for adults of I. balthica, while I. hectica indicated a major contribution of algal material. C. prismatica showed an intermediate diet. This trophic diversity is probably one of the factors allowing these species to coexist in the same biotope.

? Candidatus Hepatincola porcellionum? gen. nov., sp. nov., a new, stalk-forming lineage of Rickettsiales colonizing the midgut glands of a terrestrial isopod

The midgut glands (hepatopancreas) of terrestrial isopods are densely colonized by hitherto uncultivated bacteria. In the case of the Common Woodlouse, Porcellio scaber (Crustacea: Isopoda), the symbionts represent a novel lineage in the alpha-subdivision of Proteobacteria. Based on comparative sequence analysis of their 16S rRNA genes, their closest (albeit distant) relatives were among the Rickettsiales, which are intracellular symbionts or pathogens of many animals. Transmission electron microscopy and in situ hybridization with fluorescently labeled oligonucleotide probes revealed a homogeneous population of symbionts intimately associated with the endothelium of the hepatopancreas, which apparently interact with the microvilli of the brush border by means of a stalk-like cytoplasmic appendage. Based on isolated phylogenetic position and unique cytological properties, the provisional name ' Candidatus Hepatincola porcellionum' is proposed to classify this new taxon of Rickettsiales colonizing the hepatopancreas of P. scaber.
