Keeb kwm thiab lub hom phiaj: Molybdenum (Mo) yog ib qho tseem ceeb hauv kab rau cov nroj tsuag siab dua.Nws tau raug pom tias daim ntawv thov ntawm Mo txhim kho qhov txias tsis kam ntawm lub caij ntuj no hom qoob mog.Txhawm rau txhim kho peb txoj kev nkag siab ntawm cov txheej txheem molecular ntawm kev tiv thaiv khaub thuas uas tshwm sim los ntawm kev siv Mo hauv lub caij ntuj no cov nplej, kev tshawb nrhiav tau hais txog kev hloov pauv ntawm cov tshuaj tiv thaiv kab mob khaub thuas (COR) cov noob hauv abscisic acid (ABA)-dependent thiab ABA-kev ywj pheej txoj hauv kev. lub caij ntuj no nplej tswj los ntawm Mo daim ntawv thov nyob rau hauv qis-kub kev nyuaj siab.
Cov txheej txheem: Ob cultivars ntawm lub caij ntuj no nplej (Triticum aestivum), Mo-efficient cultivar '97003' thiab Mo-inefficient cultivar '97014', tau zus nyob rau hauv tswj (-Mo) thiab Mo chiv (+Mo) kev kho mob rau 40 d ntawm 15/12 degrees C (hnub / hmo ntuj), thiab tom qab ntawd qhov kub thiab txias tau txo mus rau 5/2 degrees C (hnub / hmo ntuj) los tsim kom muaj kev kub ntxhov.Aldehyde oxidase (AO) cov dej num, ABA cov ntsiab lus, cov ntaub ntawv sau tseg ntawm cov leucine zipper (bZIP)-type transcription factor (TF) genes, ABA-dependent COR noob, CBF/DREB transcription factor noob thiab ABA-independent COR noob tau tshawb xyuas ntawm 0 , 3, 6 thiab 48 h tom qab txias txias.
Cov txiaj ntsig tseem ceeb: Mo daim ntawv thov nce AO kev ua ub no, qib ABA, thiab kev qhia ntawm bZIP-hom TF noob (Wlip19 thiab Wabi5) thiab ABA-dependent COR noob (Wrab15, Wrab17, Wrab18 thiab Wrab19).Mo daim ntawv thov nce qib qhia ntawm CBF / DREB transcription yam noob (TaCBF thiab Wcbf2-1) thiab ABA ywj siab COR noob (Wcs120, Wcs19, Wcor14 thiab Wcor15) tom qab 3 thiab 6 h raug rau qhov kub thiab txias.
Cov lus xaus: Mo tej zaum yuav tswj cov kev qhia ntawm ABA-dependent COR noob los ntawm txoj kev: Mo --> AO --> ABA --> bZIP --> ABA-dependent COR noob nyob rau lub caij ntuj no nplej.Cov lus teb ntawm ABA-dependent txoj hauv kev rau Mo yog ua ntej ntawm txoj kev ABA-kev ywj pheej.Qhov zoo sib xws thiab qhov sib txawv ntawm Mo-efficient thiab Mo-inefficient nplej cultivars nyob rau hauv teb rau Mo nyob rau hauv txias kev ntxhov siab yog tham.
