Timabzala mbewu ndi ubongo?

Bzalani njere angagwiritse ntchito ting'onoting'ono "ubongo" kuthandiza iwo kusankha kumera kapena kukhala mu mkhalidwe chilichonse. Izi zikuonekera bwino ndi phunziro la sayansi.

Izi mbewu "ubongo" alibe mwambo imvi kanthu monga munthu, koma pokonza mfundo lidalembedwa limagwirira chomwecho ndi ntchito ya Chigawo wathu. Zomera kugwa kumasulira chizindikiro kwa mahomoni, kusankha akayamba kumera.

Zomera ali ngati anthu

"Chipinda ali ngati anthu m'njira yakuti iwo kuganiza ndi kusankha, monga tili," - anati phunziro Co-wolemba Dzhordzh Bassel, ndi zamoyo pa yunivesite ya Birmingham ku England. Malinga Bassel, anthu kupanga zisankho pogwiritsa ntchito kagulu ka maselo yapadera ya ubongo ili ubongo.

"Monga munthu akugona mkati mbewu pali chiwerengero chochepa kwambiri cha maselo kusankha zina. Maselo amenewa ndi ofanana ndi maselo ya ubongo, "- anati Bassel mu Live Science magazini.

Malinga ndi wasayansi ndi, ofufuza tsiku lina ntchito maganizo kukhala mbewu kumera pa nthawi yomweyo aliyense nyengo, komanso amateteza kwambiri ndi kusintha kwa nyengo.

Chakudya cha ganizo

Ganizo lakuti zomera kumva, kumva kapena kuona mdziko sayansi mwamtheradi si chatsopano. Ofufuza wasonyeza kuti mbewu zimere pansi ena phokoso pafupipafupi kapena imathandizira kukula, pamene pafupi mitundu ina kupikisana. Ndipo, malinga ndi kafukufuku mu 2007 (limafotokonzera magazini Oecologia), zomera zingathe kulankhulana wina ndi mzake pamene iwo ali pangozi.

Kotero, molingana ndi zamoyo Bassel, lingaliro la "kulingalira" za zomera si monga N'zokayikitsa ngati zingaoneke koyamba. Mmodzi wa maumboni amene processing zolondola zokhudza chilengedwe ndi ovuta kupulumuka kwa mbewu, ndi nthawi kumera mbewu.

Udindo wa mbewu

Mbewu zimapanga njira yokhayo imene chomera angachititse mtunda ndithu chilengedwe zosafunika chifukwa inali njira yopulumutsira abwino kwambiri. Iwo amatha kuyenda kutali zikudyedwa ndi nyama, kapena adatengedwa ndi mphepo. Malinga Bassel, mwanjira imeneyi chomera amagwiritsa njira imodzi kuyenda mu nthawi ndi malo. Basel ananena kuti mbewu matalala ndi pansi kwa nthawi yaitali kutentha kapena zinthu zina zolakwika. Iwo amatha konza mpata kupulumuka.

Zomera kuganiza limagwirira

Kumvetsa mmene zomera kupanga zosankha, wasayansi ndi anzake analenga Buku la mapu digito aliyense mazira selo lililonse (mbewu) zomera tala kapena Arabidopsis thaliana. Akatswiri ndiye Anakaligawa malo omwe mahomoni ena, monga ulamuliro, ili mkati mbewu.

Iwo anapeza kuti mahomoni awiri amene amadziwika kuti udindo mu kumera, gibberellin (GA) acid abscisic (Aba), ali woipa mkulu mu nsonga za muzu embryonic.

Maselo 3000-4000 ali mbewu pafupifupi 25 40, zikuoneka unachita lalikulu mu processing mahomoni izi. Mbali ina ya maselo kutulutsa mahomoni GA, amapereka mbendera kumera, pamene gawo lina la maselo ili kutali umatulutsa Aba, ndi chizindikiro zimene zimalimbikitsa "kukhala mu maloto." Kafukufuku akusonyeza kuti mahomoni amatumizidwa pakati zizindikiro.

"Kugwiritsa ntchito zizindikiro ziwiri chimapereka kukula ndi kuchiletsa", - anati Bassel mu Live Science.

Mu mpumulo wa khungu kubala Aba kwambiri kuposa GA. Ndipo ndi kusintha kwa zinthu ndi mlingo mbewu GA timadzi ukuwonjezeka pang'onopang'ono malinga ngati "malo a zochita" mbewu amayamba kuonetsa kuti ndi bwino kuyamba kumera, kuposa kukhala mu mkhalidwe zina. limagwirira Izi anafotokozedwa ndi ofufuza ku ntchito ya sayansi, m'magazini yotchedwa Zokambirana za Academy National wa Sciences.

kumera nthawi

Gulu la ofufuza anafika kusintha yokumba timadzi ta m'thupi la ntchito zomera. Zochitika zasonyeza kuti ndi zikugwira timadzi ta m'thupi ndi kusonyeza HIV nthawi, mbewu kumera angathe kulamulira nthawi.

"The mbewu za zomera kupanga zinthu ziŵiri zotsutsana likulu la zovuta ali olekanitsidwa ndi mtunda wina. Komanso mu galimoto kotekisi ya ubongo wa munthu ali hemispheres awiri osiyana kuyambitsa zoyenda kapena kupuma, "- anati Bassel.

"Mu nyama, kulekana kwa malo awa awiri chindiletsa mwangozi kugula kwa thupi la kukakamizidwa kutenga kusankha zolakwika" - wasayansi taonera.

Research watsimikizira kuti gulu mbewu pakati pa zigawo "kukula" ndi "mtendere" cholinga kusankha zochita pa moyo wawo, yotithandiza kumera mu nthawi pamene yozungulira kutentha zikusintha. Si bwino chifukwa yofanana kutentha kukhala wofunika kwambiri kwa zomera, koma chimodzi mwa zifukwa kwagona kuti ndondomeko zimenezi zimathandiza zomera kuona mmene mizu awo m'kati mwenimweni mwa nthaka. Chozama iwo kwambiri, buffered ndi kusintha kutentha. "Chinthu china ndi kusinthasintha kutentha ananena pamene kusintha nyengo zambiri. Kusintha angathandize mbewu kuona nyengo yosintha "- anati Bassel.

The commonality pakati pa nyama ndi zomera

"Ganizo gulu la zomera ndi nyama, kapangidwe ubongo n'zosangalatsa kwambiri chifukwa cha nyama ndi zomera ndi bwino kusanduka ku nyumba yomweyo anatomical," - anati Bassel. Malinga ndi kufufuza kwatsopano sayansi, kholo limodzi la nyama ndi zomera anali m'chipinda limodzi, algae zofanana, chamoyo chimene chinalipo zaka mabiliyoni 1.6 zapitazo.

Malinga anapeza sayansi, lofalitsidwa mu 2002 mu magazini Science, ngakhale kusiyana aakuluwa zamoyo zinachita, nyama ndi zomera ntchito pa mfundo, zomwe zinawathandiza mwayi idaona kuti chilengedwe kusintha. "Ndipo zomera ndi nyama, chifukwa mchitidwe wa chisinthiko, kusinthidwa mu njira zofanana" - anati Bassel.
