High impact information on Arcidae

• Here, I have applied calibration dates from the fossil record to cytochrome c oxidase-1 (CO1) and nuclear histone-3 (H3) divergences among six pairs of geminates in the Arcidae to test this hypothesis [1].
• Ana-1, a repetitive element with similar features, was discovered in the blood ark Anadara trapezia by probing a genomic library with a dimeric repeat element contained in intron 2 of a minor globin gene in that species [2].
• B. lima alpha and beta chains show about 50% sequence identity with the alpha and beta chains, respectively, of tetrameric haemoglobin from a related clam, Anadara trapezia [3].
• The organization of the beta-globin gene of the bivalve mollusc Anadara trapezia and its evolutionary relationship to other invertebrate and vertebrate globin genes [4].
• Purification and partial characterization of a heparin-binding lectin from the marine clam Anadara granosa [5].

Biological context of Arcidae

• PCR amplification of partial mRNA sequences encoding the alpha- and beta-globin chains of the bivalve mollusc Anadara trapezia: correction of the C-terminal amino acid sequence of the alpha-chain [6].

Associations of Arcidae with chemical compounds

• Purification and partial characterization of a N-glycolylneuraminic acid specific lectin from the clam Anadara granosa (L) [7].
• An extensive study on Se accumulation in a population of Anadara trapezia from a marine lake is reported [8].
• Consumption of seafood, in particular of clams (Anadara spp.) from the more contaminated areas, may expose the population to unacceptably high intake of toxaphene, 30 microg d(-1) per person, with the diet [9].
• Induction of a putative metallothionein gene in the blood cockle, Anadara granosa, exposed to cadmium [10].
• It was used to record the responses of Anadara granosa, an arcid clam harvested from coastal waters of Bombay, to a chemical toxicant (10 ppm CuSO4) after 96 hr exposure to naphthalene (5, 10 and 15 ppm) [11].

Gene context of Arcidae

• Hemoglobin (Hb II) of the blood clam Anadara broughtonii has a alpha 2 beta 2 sub-unit structure in athe oxy form with a sedimentation constant of 4.8 S [12].
• (1) The structures of genes of the single-domain globin chains of the annelid Lumbricus and the mollusc Anadara, and the globin gene coding for the two-domain chains of the clam Barbatia, are similar to the vertebrate plan [13].
