From jmallet at oeb.harvard.edu Thu May 17 17:43:10 2012 From: jmallet at oeb.harvard.edu (Jim Mallet) Date: Thu, 17 May 2012 12:43:10 -0400 Subject: [TABD] Butterfly genome reveals promiscuous exchange of mimicry adaptations among species - Nature.com Message-ID: <4FB52A9E.2070406@oeb.harvard.edu> The Heliconius genome paper, with evidence for colour patterns being exchanged among multiple species, is out at last! See: http://www.nature.com/nature/journal/vaop/ncurrent/full/nature11041.html Summary: The evolutionary importance of hybridization and introgression has long been debated^1 . Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferring beneficial traits between species. Here we use genomic tools to investigate introgression in/Heliconius/, a rapidly radiating genus of neotropical butterflies widely used in studies of ecology, behaviour, mimicry and speciation^2 ,3 ,4 ,5 . We sequenced the genome of/Heliconius melpomene/and compared it with other taxa to investigate chromosomal evolution in Lepidoptera and gene flow among multiple/Heliconius/species and races. Among 12,669 predicted genes, biologically important expansions of families of chemosensory and/Hox/genes are particularly noteworthy. Chromosomal organization has remained broadly conserved since the Cretaceous period, when butterflies split from the/Bombyx/(silkmoth) lineage. Using genomic resequencing, we show hybrid exchange of genes between three co-mimics,/Heliconius melpomene/,/Heliconius timareta/and/Heliconius elevatus/, especially at two genomic regions that control mimicry pattern. We infer that closely related/Heliconius/species exchange protective colour-pattern genes promiscuously, implying that hybridization has an important role in adaptive radiation.

Es gente de todo tipo de profesiones ?y estilos de vida. es una opci?n buena para aquellos viajeros que no tienen mucho presupuesto o que no encuentran un hotel o hostel a la hora de llegar al?pa?s. Adem?s las personas te ayudan a guiarte en la ciudad. a continuaci?n el link y si quieren me escriben y les explico como funciona la red de viajeros. www.couchsurfing.org ? saludos y feliz noche HUMBERTO CALERO MEJIA Estudiante de?Biolog?a Socio?Fundaci?n SAMANEA ________________________________ BETO-PTERO? ________________________________ De: Jorge Bizarro Para: TABDP lista emails Enviado: Martes, 22 de mayo, 2012 8:01 P.M.
