WebWe found cryonotothenioids have a similar complement of TRP channels as other teleosts (28 genes). Previous work has shown that thermosensitive gating in a given channel is species specific, and multiple channels act together to sense the thermal environment. Therefore, we combined evidence of changes in selective pressure, gene gain/loss ... Webcryonotothenioids to accommodate extreme anemia. Recent studies of the erythroid system in notothenioids have focused on the evolution of specific candidate genes, most notably the alpha- and beta-globin genes of the teleost globin clusters. These genes are almost completely deleted from the genomes of most icefishes [8–10],
