Zusammenfassung: | Disclosed is a DNA construct containing a promoter (hsp80) from cauliflower (Brassica oleracea) or the deletion derivatives operatively linked to a heterologous coding sequence. The hsp80 promoter is a constitutive promoter but is also heat inducible and it provides for constitutive expression of heterologous genes in a wide range of tissues and organs. There is further disclosed a method of regulating heterologous gene expression in an eukaryotic host which method can be characterised in that plant cells or plant protoplasts are transformed by said DNA construct, then transformed cells or protoplasts are selected and the transformed plant that expresses the heterologous gene is recovered.
Opísaný je DNA konštrukt, obsahujúci promótor hsp80 z karfiolu (Brassica oleracea) alebo jeho delečné deriváty, operatívne spojený s heterológnou kódujúcou sekvenciou. Promótor hsp80 je konštitutívny a zároveň indukovateľný teplom a umožňuje konštitutívnu expresiu heterológnych génov v rozsiahlom rade tkanív a orgánov. Ďalej je opísaný spôsob regulácie expresie heterológneho génu v eukaryotickom hostiteľovi, ktorý spočíva v tom, že sa transformujú rastlinné bunky alebo protoplasty uvedeným DNA konštruktom, vyberú sa tie bunky alebo protoplasty, ktoré boli transformované, regenerujú sa a vyberie sa transformovaná rastlina, ktorá exprimuje uvedený heterológny gén.ŕ |
