<prompt> Fingqa isihloko: Ucwaningo olusha lwase - United States lungase lukwenze ucabange kabili ngaphambi kokuluma ucezu lukasaladi. Ososayensi bathi izitshalo ziyakwazi ukuzizwa zidliwa ziphila futhi ezinye ziyakwazi ngisho nokusho ukuthi luhlobo luni lwesidalwa esizihlaselayo. Lokhu kwatholakala ngemva kokuhlolwa kwesitshalo i-Arabidopsis okwatholakala ukuthi siyakwazi ukuhlukanisa phakathi kwezinambuzane ezisidlayo ngokusekelwe endleleni ezihlafuna ngayo nasekuchitheni kwazo amathe. Skrolela phansi ukuze ubone ividiyo. Ucwaningo olusha lwase-US lungakwenza ucabange kabili ngaphambi kokuluma ucezu lukasawoti.Ososayensi bathi izitshalo zingazizwa zidliwa ziphila futhi ezinye zingakwazi ngisho nokutshela ukuthi hlobo luni lwesidalwa esizihlaselayo. Akumangazi ukuthi izitshalo zasabela ngendlela ehlukile lapho amaqabunga azo ehlafunwa umnenke noma emuncwa i-aphid, kusho uHeidi Appel, usosayensi ongumcwaningi ophakeme e-University of Missouri etshela i-Washington Post. Okwasimangaza kwakuwukuthi izitshalo zaziphendula ngezindlela ezingafani kanjani kumaneva nakuma-aphid. Lezi zitshalo zazikwazi ukuhlukanisa izinambuzane ngokucacile - kubonakala sengathi ziyazi ngempela ukuthi ubani ohlaselayo. UProfesa Appel waveza iqembu le-Arabidopsis, eyingxenye yomkhaya weklabishi, kumagundane ezinambuzane zezimvemvane zeklabishi nasezimpungeni ze-beet army. Wabikezela ukuthi njengoba izinambuzane zidla lesi sitshalo, i-Arabidopsis yayingasho ngokunyakaza kokuhlafuna kanye ne-saliv ukuthi leso silwane siyisimvemvane noma siyimbungu. UHeidi Appel ngakwesobunxele noRex Cocroft ngakwesokudla ngaphambili baqhuba ucwaningo olwathola ukuthi izitshalo zingabona imisindo eseduze, njengomsindo wokudla, bese zisabela ezinsongweni ezisendaweni ezihlala kuyo. Futhi wayekholelwa ukuthi lesi sitshalo sasikwazi ukuhlukanisa izinambuzane ezihlukahlukene, ngisho nalapho zidla amaqabunga ngasikhathi sinye. Ukuze ahlole inkolelo yakhe, wavuna i-Arabidopsis ehlafunwe, wakhipha izakhi zayo zofuzo, wayeseyifaka emakhazeni endaweni yokucwaninga. Izitshalo zizama ukuzivikela ngokusebenzisa izindlela ezihlukahlukene, njengokukhipha ukunambitheka okunoshukela nephunga elibi. Lezi zindlela zokuzivikela zivezwa ezakhini zofuzo. Abacwaningi baseBonn, eJalimane, bathola ukuthi izitshalo zikhipha igesi lapho zihlaselwa. Imibhobho enobuhlakani obukhulu yathola umsindo wokuqhuma ovela esitshalweni esiphilile. Kodwa...  <response>: Ososayensi baveza isitshalo i - Arabidopsis ezinambuzaneni nasezintuthwaneni. Bathola ukuthi izintuthwane zikhiqiza amathe amaningi lapho zidla iqabunga lesitshalo. Ukuhlolwa kwezakhi zofuzo esitshalweni kwembula ukuthi sasiphendula ngendlela ehlukile ezimbanjeni. Ososayensi bathola ukuthi lesi sitshalo sasikwazi ngisho nokuhlukanisa izintuthwane ezihlukahlukene. Ucwaningo lwangaphambilini lwathola ukuthi izitshalo ziyakwazi ukubona imisindo eseduze, njengokudla.
