Cov kws tshawb fawb University of Idaho tab tom qhia cov noob los ntawm cov nroj tsuag hauv tsev neeg hmo ntuj rau hauv cov qos yaj ywm, nrhiav kev tsim cov spuds uas tiv thaiv cov nematodes. Cov nroj tsuag, hu ua 'litchi txiv lws suav', muaj ntuj tiv thaiv rau ntau hom cyst thiab hauv paus-knot nematodes.
Allan Caplan, tus kws tshaj lij hauv U ntawm kuv Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Txog Kev Tshawb Fawb tau hais tias "Qhov ntawd yog qhov txawv txav uas muaj kev tawm tsam dav dav,"
Nematode cysts tuaj yeem nyob twj ywm hauv thaj teb rau ntau tshaj kaum xyoo, thiab lawv tuaj yeem pom mus txog 3 feet tob hauv av.
U ntawm kuv cov kws tshawb fawb - coj los ntawm nematologist thiab cog pathologist Louise-Marie Dandurand - tau ua haujlwm rau ntau xyoo kawm txog ntau yam muaj peev xwm siv litchi txiv lws suav ua ib qho cuab yeej los tiv thaiv nematode-txog cov qoob loo poob hauv qos yaj ywm. Litchi txiv lws suav tau cog raws li "cuab qoob loo" hauv qhov kev pab cuam kom tshem tawm daj ntseg cyst nematode (PCN), uas raug cais tawm hauv thaj tsam me me ntawm sab hnub tuaj. Idaho. Thaum cog rau hauv thaj teb uas muaj kab mob PCN, litchi txiv lws suav txhawb cov hlwv kom hatch thaum tsis muaj tus tswv tsev, ua rau lawv tshaib plab.
Dandurand kuj tseem muaj cov kws tshawb fawb tom qab kws kho mob nrhiav kev txheeb xyuas cov tshuaj hauv litchi txiv lws suav uas ua mob lossis tua cov nematodes. Cov tshuaj uas ua pov thawj tias muaj txiaj ntsig zoo tuaj yeem ua kom zoo dua thiab siv ncaj qha rau thaj chaw ua tshuaj tua kab.
Caplan thiab Fangming Xiao, tus xibfwb hauv Department of Plant Sciences, tau ua haujlwm los txheeb xyuas cov noob hauv litchi txiv lws suav uas tau qhia tshwj xeeb thaum nematodes tua cov nroj tsuag.
Caplan tau hais tias "Peb pom tsawg kawg 277 cov noob uas tau qhib," "Peb xav tias tsis yog txhua tus ntawm lawv tsim nyog. Peb yuav tsum ua kom paub kev kwv yees uas yuav tsum tau sim ua ntej, thiab nws yog ib qho teeb meem ntawm kev sim thiab ua yuam kev. Peb paub tseeb tias qee qhov ntawm cov no yuav muaj txiaj ntsig loj tab sis peb tsis tuaj yeem hais kom paub tseeb tias qhov twg lawv yuav yog. "
Lawv tau muab qee cov noob caj noob ces lawv xav tias yuav cuam tshuam ncaj qha rau kev tua cov nematodes rau Joseph Kuhl, tus kws tshaj lij hauv Department of Plant Sciences, uas tau siv biotechnology los qhia lawv rau hauv cov qos yaj ywm liab, Desiree, lub caij ntuj sov dhau los. Desiree raug xaiv vim nws yooj yim los hloov los ntawm kev hloov kho caj ces.
Caplan tau hais tias "Yog tias peb pom kev tawm tsam hauv Desiree ces peb yuav siv zog los tso rau hauv russets," Caplan tau hais.
Xiao tau tsim qee cov qos yaj ywm biotech siv litchi txiv lws suav noob lub caij nplooj zeeg dhau los, thiab Caplan tau npaj los qhia ntxiv cov noob txiv lws suav rau hauv cov qos yaj ywm rau lub caij ntuj sov no. Tag nrho lawv txoj kev loj hlob, kis kab mob thiab kev tshuaj ntsuam xyuas yog ua nyob rau hauv cov tsev loj hlob kaw.
Los ntawm thawj zaug siv genetic engineering los nrhiav txoj hauv kev los ntawm litchi txiv lws suav tiv thaiv nws tus kheej, Caplan ntseeg tias cov kws tshawb fawb tom qab tuaj yeem hloov cov noob qhia los tiv thaiv cov qos yaj ywm los ntawm nematodes los ntawm kev sim tshuaj uas tsis suav tias yog kev hloov pauv caj ces.
Cov kev tshawb fawb tau txais nyiaj txiag los ntawm ntau qhov chaw suav nrog Idaho Potato Commission, Northwest Potato Consortium thiab tsoom fwv txoj cai tiv thaiv tsob ntoo.
