Expression

Organism Comment Expression
Rebecca salina the expression is reduced when Pavlova salina is grown at 15°C. The ratio of expression of desaturases in samples grown at 25°C and 20°C, is 5times greater for the DELTA4-desaturase than for the DELTA5-desaturase gene down
Rebecca salina higher growth temperature increases the expression of front-end desaturase genes up
