WASHINGTON - Chav ua noj-xaum Argentine ntsaum muaj qhov tsis hnov ntxhiab thiab hnov qab thiab muaj lub zais hluav taws xob thaiv nrog cov khoom phem, cov kws tshawb fawb uas ua tiav nws cov genome tau hais rau hnub Monday.

Kev paub ntau ntxiv txog tias cov kab tsuag daj ua haujlwm zoo li cas tuaj yeem pab rhuav tshem cov kev hem thawj loj dua uas lawv ua rau cov qoob loo thiab cov hom ib txwm nyob, hais tias txoj kev tshawb fawb hauv phau ntawv Kev Tawm Tsam ntawm National Academy of Sciences.

Neil Tsutsui, tus kws tshaj lij ntawm UC Berkeley Lub Chaw Haujlwm Ib Cheeb Tsam tau hais tias "Lub paum Argentine yog ib hom kev txhawj xeeb tshwj xeeb vim tias nws qhov kev nyab xeeb muaj txiaj ntsig zoo."

"Thaum lub ntsaum Argentine ntxeem tau, lawv ua rau cov zej zog kab nyob ib puag ncig thaum txhawb cov pej xeem kev ua qoob loo ntawm cov tsiaj qoob loo," Tsutsui, tus kws sau ntawv nyob rau ntawm Argentine ntshuam ntawv thiab co-author ntawm ob lwm cov ntawv ntawm cov genomes ntawm tus neeg suav liab thiab nplooj. -tej hloov cov ntsaum.

"Daim ntawv qhia genome no yuav muab cov peev txheej zoo rau cov neeg txaus siab nrhiav qhov ua tau zoo, kev xav paub ntawm txoj kev tswj hwm tus cwjpwm hauv Argentine."

Lub phiaj xwm genome pom tau tias Argentine ntsaum muaj lub siab zoo 367 hnov ntxiv rau hnov tsw thiab 116 rau saj, ntau tshaj ob npaug ntawm zib ntab lub peev xwm rau tsis hnov tsw thiab yuav luag zoo tshaj li lub yoov tshaj 76 lub suab hnov.

"Ants yog cov neeg nyob hauv av, taug kev taug txoj kev taug, thiab rau ntau tus, nyob rau feem ntau ntawm lawv lub neej hauv qhov tsaus ntuj, yog li nws ua rau pom tau tias lawv yuav tau tsim kom muaj kev xav hnov tsw thiab hnov qab," said Tsutsui.

Cov ntsaum kuj tseem pom tias tau hloov mus rau ntau yam tshuaj lom lawv yuav ntsib hauv lawv cov zaub mov noj los ntawm kev txhim kho "ntau ntawm cytochrome P450 noob, uas yog qhov tseem ceeb hauv kev tshem tawm cov tshuaj phem," txoj kev tshawb no hais.

"Cov ntsaum Argentine muaj 111 cov tsiaj ntawv zoo li no, thaum nyob sab Europe muaj zib ntab zib, hauv kev sib piv, muaj 46."

Thaum lub sij hawm Argentine ntsaum yuav ua tau zoo tshaj li ntawm zib ntab hauv qee qhov, hauv kev sib raug zoo ob leeg zoo sib xws, txhua tus nrog tus poj huab tais uas muaj lub luag haujlwm rau kev rov ua dua nyob rau hauv pawg thiab cov neeg ua haujlwm uas nrhiav noj.

"Tam sim no peb paub tias ants muaj cov caj thiab genome kos npe ntawm DNA methylation - tib lub tshuab molecular uas tau tshaj tawm cov kev tshawb fawb tawm honeybee tau qhia lub luag haujlwm rau kev hloov seb cov genome yog nyeem los ua haujlwm lossis poj huab tais," said Christopher Smith, tus kws tshaj lij pabcuam ntawm kev kawm txog tsiaj txhu hauv San Francisco State University, tus kws sau txog peb ntawm plaub qhov kev tshawb fawb genome.

Cov kev kawm ntxiv txog tus ntsaum cov noob, tshwj xeeb yog cov uas ua rau muaj kuab lom hauv nws, tuaj yeem pab txiav txim siab tias cov ntsaum tiv taus cov tshuaj tua kab, thiab tejzaum txav cov kws tshawb nrhiav mus rau txoj hauv kev tshiab los tua lawv.

Tab sis cov kev tsim kho no tuaj yeem siv sijhawm ntev, thiab yog qhov dag ntxias ntau dua li lawv yuav tshwm sim.

"Hauv kev qhia txog biology, lub tswv yim yog tias ib zaug peb paub lub genome ntawm cov kab tsuag. Peb tuaj yeem ua lub ntsej muag sib tua lossis lub ntsej muag mos txwv kom yeej nws," Smith hais.

"Hauv kev muaj tiag, cov genome tsuas yog cov ntaub ntawv xwb; tam sim no peb yuav tsum muab qhov ntawd coj los ua, thiab txhawm rau ua kom tau li ntawd, peb yuav tsum tau sim kho cov ntsaum kom paub meej tias yog lub hom phiaj noob ua dab tsi peb xav tias nws ua," nws hais.

"Muaj genome zoo li raug xa mus ua ib phau loj uas muaj cov lus peb tsis nkag siab. Tam sim no peb yuav tsum paub cov txheej txheem lus thiab ntawv cim."
