Dark CO2 Fixation in Avocado Roots, Leaves, and Fruit
In a previous study avocado roots fixed CO2 about as rapidly as orange and lemon roots but much slower than bean roots (2). However, homogenates of avocado roots or leaves did not fix CO2. This study was made to explore reasons for the failure of homogenates of avocado to show CO2 fixation, and also to understand more of the relatively low degree of CO2 fixation by avocado roots in. case it may...
متن کاملC-labeled Assimilates in Grapefruit: Light and Dark CO2 Fixation by Leaves and Fruit
Distribution of radiolabeled assimilates was examined at various intervals after 1 hour of light or dark 14CO2 fixation by leaves or developing fruit of grapefruit (Citrus paradisi Macf.) so that the fate of assimilates from each source could be assessed at sequential stages of fruit growth. Exported products of both light and dark 14CO2 fixation in leaves were deposited primarily in juice tiss...

متن کاملHigh abundance and dark CO2 fixation of chemolithoautotrophic prokaryotes in anoxic waters of the Baltic Sea
We determined the abundance and distribution of chemolithoautotrophic prokaryotes in the redoxcline in two basins (Gotland Deep, Landsort Deep) of the central Baltic Sea by combining dark CO2 fixation measurements with flow cytometric cell sorting. Maximum CO2 fixation rates were recorded in sulfidic waters about 20 m below the chemocline. Flow cytometric analyses of deoxyribonucleic acid (DNA)...
متن کاملMultigene manipulation of photosynthetic carbon assimilation increases CO2 fixation and biomass yield in tobacco
Over the next 40 years it has been estimated that a 50% increase in the yield of grain crops such as wheat and rice will be required to meet the food and fuel demands of the increasing world population. Transgenic tobacco plants have been generated with altered combinations of sedoheptulose-1,7-bisphosphatase, fructose-1,6-bisphosphate aldolase, and the cyanobacterial putative-inorganic carbon ...
