Characterization of reproduction-specific genes in a marine bivalve mollusc: Influence of maturation stage and sex on mRNA expression

Transcriptomic response of Argopecten purpuratus post-larvae to copper exposure under experimental conditions

“…The same physiological functions have been shown to be affected in similar studies of other stresses in C. gigas, including hydrocarbon exposure (Boutet et al, 2004), infection by parasites , and exposure to herbicides . In scallops, both physiological processes have been shown to be regulated in response to either defense against parasite in A. irradians, (Song et al, 2006) and during gametogenesis in A. purpuratus (Boutet et al, 2008). In our study, genes associated with the respiratory chain were up-and down-regulated.…”

Expressed sequence tags from the zhikong scallop (Chlamys farreri): Discovery and annotation of host-defense genes

“…As a possible result of bacterial challenge, relatively high numbers of stress/defenserelated unigenes were successfully identified in this library. The results from oysters and scallops collectively indicated that the genes related to metabolic processes and host defense were relatively abundant in ESTs of marine bivalves [16,17,23]. In the present study, a total of 213 unigenes were found to be related to immune defense (Table 2), which consisted of 89 contigs representing 522 ESTs and 124 singletons, totaling 646 ESTs.…”

“…EST collections are relatively small for scallops. Except for our EST analysis in bay scallop [16,23], only one study reporting 425 ESTs from bay scallop has been published [24]. There was no EST sequence in GenBank for zhikong scallop before this study.…”

Trace metal and biomarker levels in tissues ofArgopecten purpuratusin the north of Chile, and the potential use of this species as a bioindicator of metallic stress

“…Reaction component concentrations were as follows: 1× Absolute QPCR SYBR Green ROX Mix (ABgene, Epsom, UK) and 70 nM of each specific primer (Boutet et al 2008;Zapata et al 2009, Table 1). Reactions were performed with activation by Thermo-Start DNA polymerase at 95…”
