  • Fishes
  • Overall, the Runx genes in lamprey seem to have experienced a different evolutionary trajectory from that of gnathostome Runx genes which are highly conserved all the way from cartilaginous fishes to mammals. (jove.com)
  • larva
  • Chang M, Wu F, Miao D, Zhang J (2014) Discovery of fossil lamprey larva from the Lower Cretaceous reveals its three-phased life cycle. (springer.com)
  • Genetic
  • Thus, while the fluvial lamprey population does not appear to be in danger of losing genetic diversity, continued isolation is likely to affect gene flow by reducing migration between subpopulations. (semanticscholar.org)
  • jawed vertebrates
  • Cyclostomes, comprising jawless vertebrates such as lampreys and hagfishes, are the sister group of living jawed vertebrates (gnathostomes) and hence an important group for understanding the origin and diversity of vertebrates. (pnas.org)
  • The cyclostomes (jawless vertebrates), comprising lampreys and hagfishes, are the sister group of jawed vertebrates (gnathostomes) and are hence an important group for the study of vertebrate evolution. (jove.com)
  • The unique morphological characteristics of lampreys, such as their cartilaginous skeleton , suggest they are the sister taxon (see cladistics ) of all living jawed vertebrates ( gnathostomes ), and are usually considered the most basal group of the Vertebrata. (wikipedia.org)
  • Metamorphosis
  • Each period required the dramatically different morphologies seen in modern lampreys, ultimately requiring a true metamorphosis to accommodate the large changes in the body plan and to maximize the efficiency of each life period. (springer.com)
  • VLRB
  • Lamprey VLRB-expressing cells can respond to immunization by undergoing lymphoblastoid transformation, clonal expansion, and secretion of their antigen-specific VLRB antibodies ( 9 , 14 ). (pnas.org)
  • Adult
  • The adult lamprey may be characterized by a toothed, funnel-like sucking mouth. (wikipedia.org)
  • Lacking paired fins , adult lampreys have large eyes, one nostril on the top of the head, and seven gill pores on each side of the head. (wikipedia.org)
  • suggests
  • This suggests that the lamprey lineage has undergone an additional round of genome duplication compared with tetrapods. (pnas.org)
  • habitat
  • We infer that female silver lamprey cue onto 3kPZS excreted by stream-resident larvae as a mechanism to locate habitat conducive to offspring survival and that males do not signal with 3kPZS. (royalsocietypublishing.org)
  • clusters
  • Several conserved noncoding elements (CNEs) were predicted in the Hox clusters of lamprey, elephant shark, and human. (pnas.org)
  • proteins
  • The major protein domains and motifs found in gnathostome Runx proteins are highly conserved in the lamprey Runx proteins. (jove.com)
  • upstream
  • In Britain, at the time of the Conquest , lampreys were found as far upstream in the River Thames as Petersham [ citation needed ] . (wikipedia.org)
  • evolution
  • Lampreys and hagfishes (cyclostomes) are the only living group of jawless vertebrates and therefore are important for the study of vertebrate evolution. (pnas.org)
  • Control
  • Active control programs to control lampreys are undergoing modifications due to concerns of drinking water quality in some areas. (wikipedia.org)
  • life
  • The current review synthesizes these findings and concludes that the ancestral lamprey life cycle followed a direct development. (springer.com)
  • As a result, modern lamprey life histories are a patchwork of ancestral and derived characters. (springer.com)
  • The sea lamprey is a jawless vertebrate that relies upon olfaction to complete the final stages of its semelparous life [ 22 ]. (royalsocietypublishing.org)
  • sites
  • The 3'UTR of lamprey RunxB contains binding sites for miR-27 and miR-130b/301ab, which are conserved in mammalian Runx1 and Runx3, respectively. (jove.com)
