A starch sheath is often formed or deposited at the periphery of pyrenoids, even when that starch is synthesised in the cytosol rather than in the chloroplast. [19] When examined with transmission electron microscopy, the pyrenoid matrix appears as a roughly circular electron dense granular structure within the … Visa mer Pyrenoids are sub-cellular micro-compartments found in chloroplasts of many algae, and in a single group of land plants, the hornworts. Pyrenoids are associated with the operation of a carbon-concentrating … Visa mer The confinement of the CO2-fixing enzyme into a subcellular micro-compartment, in association with a mechanism to deliver CO2 to that site, is believed to enhance the efficacy of … Visa mer The CCM is only induced during periods of low CO2 levels, and it was the existence of these trigger levels of CO2 below which CCMs are induced that led researchers to speculate on the likely timing of origin of mechanisms like the pyrenoid. There are several Visa mer Pyrenoids were first described in 1803 by Vaucher (cited in Brown et al. ).
