Stefan Jansson

Jag är professor i växters cell- och molekylärbiologi och forskar om hur växterna fångar in solljuset och använder det i fotosyntesen samt om genetik och genomik i träd.

Professor vid Institutionen för fysiologisk botanik Enhet: Umeå Plant Science Centre - UmU
Plats
KB. K3 (UPSC), Artedigränd 7, Fysiologisk botanik, UPSC, KB. K3 (B3.36.45) Umeå universitet, 901 87 Umeå

Jag forskar dels om hur växterna fångar in solljuset och använder det i fotosyntesen, dels om genetik och genomik i träd; hur man på bästa sätt identifierar de gener som gör att olika trädindivider - av samma art - har olika egenskaper. De två frågor vi just nu försöker lösa är: Hur vet träden att det är höst? Hur kan granen och tallen ha gröna barr om vintern?

Min arbetsplats är på Umeå Plant Science Centre. En av de metoder jag och min grupp använder för att modifiera arvsmassa hos växter är CRISPR/cas9.

Mer information om min forskning finns på Umeå Plant Science Centre’s webbplats
