Qos sau qoob tau ntev fascinated cov kws tshawb fawb, cov neeg ua liaj ua teb, thiab agronomists ib yam nkaus. Kev tshawb fawb tsis ntev los no, raws li tau hais tseg hauv Europatat xov xwm tshaj tawm, nkag mus rau hauv cov txheej txheem sib txawv uas tswj hwm tuber tsim hauv qos yaj ywm. Lub earliness locus, ib tug tseem ceeb players nyob rau hauv cov txheej txheem no, undergoes kev hloov thaum lub sij hawm niaj hnub qos yaj ywm, cuam tshuam thaum tubers loj hlob.
Raws li qhov kev tshawb pom, qhov ntxov ntxov locus yog ze ze rau CYCLING DOF FACTOR1 (StCDF1), ib qho protein inhibiting kev qhia ntawm qos yaj ywm homologs rau CONSTANS (StCOLs). StCOLs qhib SP5G FT-zoo li noob, cuam tshuam tuberigen qhia thiab tom qab tuberization. Cov qauv luv luv ntawm StCDF1 ua raws li cov neeg tawm tsam ruaj khov, ua rau muaj kev cuam tshuam StCOLs txawm tias nyob ntev ntev, txhawb nqa tuberization.
Kev sib koom tes ntawm University of Wageningen thiab CRAG hauv Barcelona, siv RNA-Seq thiab DNA binding-affinity purification nrog high-throughput sequencing (DAP-Seq), qhia StCDF1 lub luag haujlwm dav. Nws tsis tsuas yog txwv tsis pub txoj hauv kev niaj hnub tab sis kuj tswj cov noob cuam tshuam nrog nitrogen metabolism, cuam tshuam rau kev siv nitrogen siv (NUE). Niaj hnub nimno qos cultivars nrog lub earliness locus qhia tau txo qis NUE, ua rau lawv cia siab rau nitrate chiv.
Txoj kev tshawb no nthuav tawm cov kev daws teeb meem, tawm tswv yim nce NIA2 luam los ntawm lwm cov nroj tsuag lossis tshem tawm StCDF1-binding qhov chaw los ntawm cov qos yaj ywm NIA1 txhawb kom txhim kho qos yaj ywm nitrate noj efficiency.
Hauv cov ntsiab lus loj dua, Horizon 2020 EU project ADAPT, featuring Europatat, aims to decipher signaling pathways for single and together abiotic stresses. Lub hom phiaj yog xaiv cov qos yaj ywm cultivars resilient rau kev hloov pauv huab cua, muab kev cia siab rau cov qos yaj ywm ua liaj ua teb kom ruaj khov thiab muaj zog nyob rau hauv kev sib tw ntawm ib puag ncig.
Kev nkag siab txog cov molecular intricacies ntawm qos tuber tsim tsis tsuas yog qhib txoj hauv kev rau kev txhim kho nitrate noj efficiency tab sis kuj pab txhawb rau kev tsim cov qos yaj ywm cultivars huab cua. Cov kev tshawb fawb tsis tu ncua raws li cov haujlwm xws li ADAPT qhia txog kev cog lus rau kev ua liaj ua teb kom ruaj khov, ua kom cov qos yaj ywm tseem muaj ntau yam thiab cov qoob loo zoo.
