Temperature-dependent endogenous oxygen concentration regulates microsomal oleate desaturase in developing sunflower seeds.

| Comments | "Unlike the developing seed, the sponge capitulum tissue harbouring the achenes is green and photosynthetically active. Illumination (300µE) of this tissue raised the oxygen level from 231.8±2.5µM to 241.0±2.8µM due to photosynthetic oxygen release." |
