| comparative anatomy of serotonin-like immunoreactive neurons in isopods: putative homologues in several species. | it is now commonly accepted that the arthropod nervous system has evolved only once, and so homologies between crustacean and insect nervous systems can be meaningfully sought. to do this, we have examined the distribution of serotonin (5-hydroxytryptamine)-like immunoreactive neurons in the central nervous system (cns) of four common british isopods. two species of terrestrial woodlouse, oniscus asellus and armadillidium vulgare, the littoral sea slater, ligia oceanica, and the aquatic water ho ... | 1994 | 7814675 |

| bacterial symbionts in the hepatopancreas of isopods: diversity and environmental transmission. | the midgut glands (hepatopancreas) of terrestrial isopods contain bacterial symbionts. we analysed the phylogenetic diversity of hepatopancreatic bacteria in isopod species from various suborders colonizing marine, semiterrestrial, terrestrial and freshwater habitats. hepatopancreatic bacteria were absent in the marine isopod idotea balthica (valvifera). the symbiotic bacteria present in the midgut glands of the freshwater isopod asellus aquaticus (asellota) were closely related to members of th ... | 2007 | 17506824 |
| a new cyclopeptide metabolite of marine gut fungus from ligia oceanica. | a new cyclopeptide, together with three known amino acid derivatives, was isolated from marine-derived fungus aspergillus flavipes, which was found in the gut of isopod ligia oceanica. the novel peptide contains four amino acid units, proline, 5-methoxyanthranilic acid, isoleucine and 3-aminoacrylic acid. its structure was determined on the basis of nmr, hr-ms and ms(n) spectral data analysis. the two unusual amino acid residues, 5-methoxyanthranilic acid and 3-aminoacrylic acid, were first foun ... | 2014 | 24942057 |
| widespread atypical mitochondrial dna structure in isopods (crustacea, peracarida) related to a constitutive heteroplasmy in terrestrial species. | metazoan mitochondrial dna (mtdna) is generally composed of circular monomeric molecules. however, a few exceptions do exist and among them two terrestrial isopods armadillidium vulgare and porcellionides pruinosus have an atypical mtdna composed of linear monomers associated with circular "head-to-head" dimers: a very unusual structure for animal mtdna genome. to assess the distribution of this atypical mtdna among isopods, we performed rflp and southern blot analyses on mtdna of 16 terrestrial ... | 2012 | 22376074 |
| [changes in the hemolymph protein patterns caused by certain types of intersexuality in the oniscoides ligia oceanica l. and armadillidium vulgare latr. (crustacea, isopoda)]. | the haemolymph of oostegite males of ligia oceanica and of im intersexes of armadillidium vulgare gives a hyperproteinemy owing to stocking of fractions representing vitellogenic proteins of extraovarian source. the only intersexes with ovary or ovariotestis present a vitellin proteic fraction. | 1976 | 828535 |
| the effects of temperature on peripheral neuronal function in eurythermal and stenothermal crustaceans. | to determine whether neuronal function in antarctic crustaceans is adapted to the low and narrow range of temperatures at which these animals live, we have compared conduction velocities in the peripheral nervous systems of two temperate species, the decapod carcinus maenas and the isopod ligia oceanica, and two antarctic species, the isopod glyptonotus antarcticus and the amphipod paraceradocus gibber. neuronal conduction velocity differs among the species in the order c. maenas > g. antarcticu ... | 2006 | 16651562 |
| genome sequencing and evolutionary analysis of marine gut fungus aspergillus sp. z5 from ligia oceanica. | aspergillus sp. z5, isolated from the gut of marine isopods, produces prolific secondary metabolites with new structure and bioactivity. here, we report the draft sequence of the approximately 33.8-mbp genome of this strain. to the best of our knowledge, this is the first genome sequence of aspergillus strain isolated from marine isopod ligia oceanica. the phylogenetic analysis supported that this strain was closely related to a. versicolor, and genomic analysis revealed that aspergillus sp. z5 ... | 2016 | 27081303 |
| asperginine, an unprecedented alkaloid from the marine-derived fungus aspergillus sp. | asperginine (1), an alkaloid possessing a rare skeleton, was isolated from the cultural broth of the marine fungus aspergillus sp. (z-4) isolated from the gut of the marine isopod ligia oceanica. the planar structure and relative configuration of 1 was determined by analysis of nmr and mass spectral data. its absolute configuration was elucidated by marfey's method, together with noesy correlations of key hydrogen atoms. the cytotoxicity against prostate cancer pc3 and human hct116 was assayed b ... | 2015 | 26434117 |
| methylthio-aspochalasins from a marine-derived fungus aspergillus sp. | two novel aspochalasins, 20-β-methylthio-aspochalsin q (named as aspochalasin v), (1) and aspochalasin w (2), were isolated from culture broth of aspergillus sp., which was found in the gut of a marine isopod ligia oceanica. the structures were determined on the basis of nmr and mass spectral data analysis. this is the first report about methylthio-substituted aspochalasin derivatives. cytotoxicity against the prostate cancer pc3 cell line and hct116 cell line was assayed using the mtt method. a ... | 2014 | 25272329 |
