O2 concentration in illuminated sponge capitulum tissue

Value 241 μM Range: ±2.8 μM
Organism Sunflower Helianthus annuus
Reference Rolletschek H, Borisjuk L, Sánchez-García A, Gotor C, Romero LC, Martínez-Rivas JM, Mancha M. Temperature-dependent endogenous oxygen concentration regulates microsomal oleate desaturase in developing sunflower seeds. J Exp Bot. 2007 58(12):3171-81 p.3173 right column 3rd paragraphPubMed ID17905732
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."
