När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. Denna avhandling rapporterar om flera viktiga aspekter relaterade till de cellulära och metaboliska mekanismer som sker under senescencen med tonvikt på mitokondriernas bidrag till denna process. I ett första steg utvecklade vi metoder för att isolera antingen mycket funktionella mitokondrier eller mycket rena mitokondrier från blad av Arabidopsis thaliana. Dessa metoder användes sedan till för att studera mitokondriella bidrag till cellens redox balans och att uppskatta mitokond...
