Genome evolution nyob rau hauv intracellular microbial symbionts yog tus cwj pwm los ntawm cov noob poob, tsim qee qhov tsawg tshaj plaws thiab feem ntau cov noob tsis zoo genomes paub.Raws li qhov tshwm sim ntawm cov noob poob cov genomes feem ntau muaj cov txheej txheem metabolic uas tau tawg mus rau lawv cov txheeb ze nyob dawb.Cov evolutionary tuav ntawm fragmented metabolic pathways nyob rau hauv lub gene-poor genomes ntawm endosymbionts qhia tias lawv ua hauj lwm.Txawm li cas los xij, nws tsis yog ib txwm paub meej tias lawv tswj kev ua haujlwm li cas.Txog niaj hnub no, cov txheej txheem metabolic ntawm cov endosymbionts tau pom tias muaj kev ua haujlwm los ntawm kev ua tiav los ntawm cov noob caj noob ces, ntxiv los ntawm cov noob ntawm lwm cov endosymbiont thiab ntxiv los ntawm cov noob hauv cov genomes uas tau txais kab rov tav los ntawm microbial qhov chaw uas tsis yog endosymbiont.Ntawm no, peb ua qauv qhia plaub txheej txheem.Peb tshawb xyuas qhov kev hloov pauv hloov ntawm txoj hauv kev tawg mus rau qhov tseem ceeb nutrient pantothenate (vitamin B5) hauv pea aphid, Acyrthos iphon pisum endosymbiosis nrog Buchnera aphidicola.Siv cov kev txheeb xyuas ntau ntawm cov noob qhia peb nthuav tawm cov pov thawj rau kev ua tiav ntawm Buchnera pantothenate biosynthesis txoj hauv kev los ntawm cov noob noob.Tsis tas li ntawd, siv cov kev ntsuam xyuas ntxiv hauv Escherichia coli mutant peb pom kev ua haujlwm hloov pauv ntawm pantothenate biosynthesis enzyme, 2-dehydropantoate 2-reductase (EC 1.1.1.169), los ntawm endosymbiont noob, ilvC, encoding ib substrate enzyme. uas ploj lawm enzyme cov kauj ruam nyob rau hauv fragmented endosymbiont metabolic txoj kev yog ua tiav los ntawm adaptable endosymbiont enzymes los ntawm lwm txoj kev.Ntawm no, peb sim ua kom tiav kev ua tiav ntawm ib qho kev sib cais endosymbiont vitamin biosynthesis txoj hauv kev los ntawm kev nrhiav ib lub substrate tsis meej enzyme los ntawm lwm txoj hauv kev.Tsis tas li ntawd, txoj haujlwm no txuas ntxiv kev sib koom ua ke ntawm tus tswv / symbiont metabolic hauv aphid / Buchnera symbiosis los ntawm amino acid metabolism kom suav nrog vitamin biosynthesis.
