Denna forskning stöds av den holländska Technology Foundation STW (12385), som är en del av den nederländska organisationen för vetenskaplig forskning (NWO), och som delvis finansieras av departement av ekonomiska angelägenheter (OTP Grant 12385 till MS).  Vi tackar Carol M. Hamilton (Cornell University, USA) för att tillhandahålla pCH20, ryggraden i BIBAC-GW vektorer.

Kritiska till att generera transgenics med enda, intakt integrationer av en transgen är valet av den binära vektor som används. BIBAC familj vektorer har använts för att leverera sekvenser av intressen till många växt arter23,24,25,26,27,28. BIBAC vektorer, inklusive BIBAC-GW, avkastning singel-kopia integrationer med ...

När du genererar transgena växter, är oftast målet att ha den integrerade transgene(s) stabilt uttryckt. Detta kan uppnås genom intakt exemplar integrationer av en transgen. Flera integrationer kan leda till ökat uttryck av en transgen, men också till nedtystning. Ljuddämpning av transgener är mer sannolikt om infogade sekvenserna är ordnade i tandem eller inverterad repetitioner1,2,3,4. Binärt vektorer används som Transfer i Agrobacterium-medierad omvandling experiment för att leverera sekvenserna av intresse i växten genomen. Antalet integrationer till en växt genomet är beroende av kopia antalet binära vektorn i Agrobacterium tumefaciens5,6. Många vanliga binära vektorer är hög kopia vektorer, och därför ger en hög genomsnittlig transgenens kopienumret: 3.3 till 4,9 kopior i Arabidopsis5.
Antalet T-DNA integrationer kan sänkas med hjälp av binära vektorer som har en låg-kopia nummer i A. tumefaciens, såsom BIBAC7, eller genom att lansera en T-DNA från A. tumefaciens kromosom5. Det genomsnittliga antalet transgenens integrationer i sådant fall understiger 25,8,9,10. På grund av att singel-kopia i A. tumefaciens, och även i Escherichia coli, BIBAC-derivat kan upprätthålla och leverera konstruktioner så stor som 150 kb11.
GW-kompatibel BIBAC vektorer10,12 Tillåt lätt införandet av gener av intresse i den vektor som använder Gateway kloning. Användning av Gateway teknik förenklar förfarandet för kloning, men också övervinner vanliga problem associerade med stora låg-kopia-nummer vektorer13,14, till exempel en låg DNA-avkastning och ett begränsat urval av unika begränsning platser tillgängliga för kloning7,11. PBIBAC-GW derivat finns med antingen motstånd mot glufosinatammonium (pBIBAC-BAR-GW) eller DsRed fluorescens i frö rockar (pBIBAC-RFP-GW) för urval i växter (figur 1)10,12. För båda vektorer används en kanamycin motstånd gen som urval markören i bakterier.
PBIBAC-GW vektorerna kombinera: (1) lätt design och genmanipulation i E. coli, och (2) intakt singel-kopia integrationer i planta med hög effektivitet. PBIBAC-GW vektorer avkastningen på genomsnitt 1,7 integrationer i Arabidopsis med ungefär hälften av de transgena växter som bär en enda integrerad T-DNA10.
Stabilt uttryck av transgener är ett krav för de flesta transgenics genereras. Stabil transgenens uttryck kan uppnås genom intakt, singel-kopia integrationer. Arbeta med transgena växter transporterar intakt, singel-kopia integrationer är dock ännu viktigare om exempelvis syftet är att studera effektiviteten av kromatin-baserade processer, såsom mutagenes, rekombination, eller reparation och beroendet av dessa processer på genomisk platsen och kromatinstruktur vid insticksstället. För vårt intresse, för att studera beroendet av oligonukleotiden riktad mutagenes (ODM) på lokala genomisk sammanhang, var en uppsättning reporter rader med intakt, singel-kopia integrationer av en mutagenes reporter gen genererade (figur 2)10. Med denna uppsättning linjer, visades att ODM effektivitet varierar mellan transgena loci integreras på olika genetiska platser, trots transgenens uttrycksnivåerna är ganska likartade.

generating transgenic plants with single-copy insertions using bibac-gw binary vector

När du genererar transgena växter, generellt är målet att ha stabilt uttryck av en transgen. Detta kräver en enda, intakt integration av transgenens, som flera exemplar integrationer utsätts ofta för nedtystning. Gateway-kompatibel binära vektorn baserat på bakteriella artificiella kromosomer (pBIBAC-GW), liksom andra pBIBAC derivat, tillåter införandet av single-kopia transgener med hög verkningsgrad. Som en förbättring av den ursprungliga pBIBAC, har en Gateway-kassett blivit Klonade in pBIBAC-GW, så att sekvenserna av intresse kan nu enkelt införlivas i vektor överföringen DNA (T-DNA) av Gateway kloning. Vanligen, omformningen med pBIBAC-GW resulterar i en verkningsgrad på 0,2 – 0,5%, där hälften av transgena bära en intakt singel-kopia integration av T-DNA. PBIBAC-GW vektorer finns med resistens mot glufosinatammonium eller DsRed fluorescens i frö rockar för urval i växter och motstånd mot kanamycin som en markering i bakterier. Här presenteras en serie av protokoll som guidar läsaren genom processen att skapa transgena växter med pBIBAC-GW: Start från kombinera sekvenserna av intresse i den pBIBAC-GW vektorn val, att plantera förvandling med Agrobacterium, urval av transgena och testa växterna för orördhet och kopiera antal skär med hjälp av DNA analys. Uppmärksamhet ges till att designa en DNA blotting strategi att erkänna singel - och multi - kopieringsskyddad integrationer på enstaka och flera loci.

Med hjälp av BIBAC-GW systemet, var reporter konstruktioner för att studera ODM i växter genererade10. Konstruktioner var utformad i Gateway posten vektor pENTR-gm12 och infogas i pBIBAC-BAR-GW (figur 1) med Gateway LR rekombination reaktionen.
