Journal ArticleDOI
Evidence for Multiple Reversals of Asymmetric Mutational Constraints during the Evolution of the Mitochondrial Genome of Metazoa, and Consequences for Phylogenetic Inferences
TL;DR: This work proposes a new method for limiting this specific problem in tree reconstruction under the Bayesian approach and suggests that Chelicerata, Crustacea, Myriapoda, Pancrustacea, and Paradoxopoda are monophyletic.
Journal ArticleDOI
Thermal limit for metazoan life in question: in vivo heat tolerance of the Pompeii worm.
Juliette Ravaux,Gérard Hamel,Magali Zbinden,Aurélie Tasiemski,Isabelle Boutet,Nelly Léger,Arnaud Tanguy,Didier Jollivet,Bruce Shillito +8 more
TL;DR: A comparison with hsp70 stress gene expressions of individuals analysed directly after sampling in situ confirms that Alvinella pompejana does not experience long-term exposures to temperature above 50°C in its natural environment, which confirms that the Pompeii worm ranks among the most thermotolerant metazoans.
Journal ArticleDOI
Comparison of heat-shock responses between the hydrothermal vent shrimp Rimicaris exoculata and the related coastal shrimp Palaemonetes varians
TL;DR: The first quantification of the expression of multiple hsp70 genes following heat stress in a deep-sea vent species living at 2300 m depth is reported, suggesting that the highly inducible molecular response observed in R. exoculata may contribute to the ability of this species to tolerate thermal extremes.
Journal ArticleDOI
First hsp70 from two hydrothermal vent shrimps, Mirocaris fortunata and Rimicaris exoculata: characterization and sequence analysis.
TL;DR: The HSP70 sequences from the hydrothermal shrimps proved to be very similar to the other homologous shrimp sequences, except for the presence of an insertion of unknown function in the ATPase domain of R. exoculata sequence.
Journal ArticleDOI
Adaptation to thermally variable environments: capacity for acclimation of thermal limit and heat shock response in the shrimp Palaemonetes varians.
Juliette Ravaux,Nelly Léger,Nicolas Rabet,Marina Morini,Magali Zbinden,Sven Thatje,Bruce Shillito +6 more
TL;DR: Cold and warm-acclimated specimens of P. varians can mobilise the heat shock response (HSR) at temperatures above those experienced in nature, which suggests that the species is potentially capable of expanding its upper thermal range.
