GUSHYIKIRANA
Urutonde rwa genome rugaragaza inzira zikwirakwira kwisi kandi bikerekana guhuza n'imihindagurikire y'ikirere mu bwihindurize bw'inyanja
PacBio |Illumina |Muraho-C |WGS |Ubwoko butandukanye |Amateka ya Demokarasi |Gene Flow
Urutonde rwa Pacbio, inteko ya genome de novo hamwe na annotation byatanzwe na Biomarker Technologies.
Ingingo z'ingenzi
1.Ubwoko bwa chromosome yo murwego rwohejuru (Hippocampus erectus) genome hamwe na N50 ya 15.5 Mb yabonetse.
2.Amoko yose uko ari 358 yaturutse ku isi amoko 21 yinyanja yongeye kuboneka.
3.Inyanja zagiye zihindagurika nyuma ya Oligocene hanyuma inzira zabakoloni zizenguruka isi ziramenyekana kandi bifitanye isano no guhindura imbaraga mumigezi yinyanja no gufungura inyanja ya paleotemporal.
4.Imiterere ya genetike yisubiramo ya "bony spines" ihuza imiterere ya fenotipike ihuza n'imihindagurikire yigenga muri gene yingenzi yiterambere.
5.Gucisha mu miyoboro y'inyanja byishyura imikoreshereze idahwitse kandi imihindagurikire yihuse byoroshya ubukoroni bushya
Ibyagezweho
Igishushanyo cya 1 Ubwoko butandukanye hamwe nubusabane bwa phylogeneque bwikigereranyo cya 358
aImiterere ya geografiya yerekana icyitegererezo cyinyanja hamwe nuburyo butandukanye bwa nucleotide (π) yubwoko 21 bwinyanja kuri chromosomes 22.b Igiti cyegeranye cyubatswe hamwe na genome-yagutse ya SNPs yinyanja 358.Ikibanza cya pin ibimenyetso muri (a) ninyuma yishami muri (b) bihuye.
Igishushanyo cya 2 Ubukoloni n'amateka ya demokarasi yinyanja
aIgiti cya phylogeneque nigihe cyo gutandukanya amoko 21 yinyanja.Umubyimba wumurongo wishami uhuye nubunini bwabaturage (Ne) kandi amabara yerekana imirongo itandukanye.Ibimenyetso I - III byerekana ingingo zo guhitamo.b - d Inzira zateganijwe gukoronizwa (imyambi y'amabara) yinyanja ishingiye kumwanya wo gutandukana, gukwirakwizwa, ibyabaye, hamwe ninyanja (imyambi yera).b Archipelago y'Abahinde n'Abanyaustraliya yari ihuriro ry'inkomoko (ikimenyetso gitukura) cyo mu bwoko bwa Hippocampus mbere yuko inyanja itandukana kandi ikwirakwizwa ku isi 18-23 Ma.c Seahorses yabanje gukoroniza inyanja ya Atalantika inyuze mu nyanja ya Tethyan, nyuma yo gufungwa kwayo (Ikirori cya Terminal mugihe cya 7–13 Ma), yatandukanije uyu muryango wa Tethyan numuryango wa mushiki wacyo wo mu nyanja yu Buhinde.Iheruka, nyuma itandukanye cyane (ikimenyetso cy'umuhondo) mu nyanja ya Arabiya, ishyiraho ikigo cya kabiri cyo gutandukanya inyanja.d Ikintu cya kabiri cyo gukoroniza inyanja ya Atalantika cyabereye mu nyanja yu Buhinde nko muri 5Ma unyuze ku nkombe ya Afurika yepfo, hanyuma amaherezo ugera mu nyanja ya pasifika y’iburasirazuba unyuze mu nyanja ya Panama ikinguye hafi 3.6 Ma.
Igishushanyo cya 3 Itemba ryimiterere nihindagurika mubunini bwabaturage
aUrujya n'uruza rw'ibinyabuzima rwagaragaye hagati y'ibinyabuzima bituye inyanja ya Atalantika y'Amajyepfo.Imirongo ya gen irerekanwa hafi yumurongo wera nkigipimo cyo kwimuka cyagabanijwe na G-PhoCS.Ubunini n'icyerekezo cy'imyambi bihuye n'ibipimo n'icyerekezo cya gene ikurikirana.b Imihindagurikire yubunini bwabaturage neza na PSMC.X axis igereranya igihe mumyaka mbere yubu mugihe y axis yerekana ingano yabaturage.Imbonerahamwe itunganijwe cyane cyane ukurikije ikwirakwizwa rya geografiya kuri buri bwoko hamwe n’ahantu hatandukanye.c Ihinduka ryinyanja mumyaka miriyoni ishize muri metero33.Umurongo wumuhondo werekana impinga yanyuma yisi yose mugihe igicucu cya cyan cyerekana igihe cyanyuma cyikirere.
Igishushanyo cya 4 Ubwihindurize bwumugongo.
aIbumoso, Ubwoko bwibiti byerekana ubwihindurize bwigenga bwumugongo mu nyanja.Uburebure bwishami bwerekana umubare wabasimbuye kurubuga.Ubwoko bune bwinyanja bugaragara mubururu.Amashami yimbitse ahuye nigipimo cyo hejuru cyo gusimbuza izina (dN / dS) kuri bmp3 gene.Ikizamini cya Canonical hamwe na rusange muri McDonald na Kreitman (MKT) kuri bmp3 yakorewe amoko atatu ya bashiki bacu bombi hamwe na spiny zitandukanye kandi zidafite icyerekezo cyerekanwe namabara yinyuma, urwego rwingenzi rwerekanwe nagaciro kerekana ubururu nubururu butukura.Iburyo, kugereranya insimburangingo ya aside amine muri proteine ya bmp3, polymorphique hamwe nibisimburwa bihamye mumyanyanja yinyanja byerekanwe hamwe numuzingi utukura nubururu.b Gukwirakwiza indangagaciro za dN / dS muri bmp3 mu nyanja nini ugereranije nubwoko butari bwiza.c Ubwihindurize bwigenga mubiti bya phylogeneque byubatswe kuri poroteyine yashizweho na bmp3.d Byose byuzuye muburyo bwa Hybridisation ya bmp3 muri Hippocampus erectus.
