WebC-4 photosynthesis is photosynthesis used for specific C-4 plants, and instead of producing a 6-carbon molecule as its first product, it produces a 4-carbon molecule. Photorespiration is used when a plant can't get enough CO2 for normal photosynthesis, so it uses O2, and this process later releases CO2.

WebThe efficient C4 pathway is based on strong up-regulation of genes found in C3 plants, but also compartmentation of their expression into distinct cell-types such as the mesophyll and bundle sheath. Transcription factors associated with these WebJul 3, 2024 · The maize is a C4 plant with Kranz anatomy in which functionally distinct chloroplasts are separately located in the mesophyll cell (MC) and in the bundle sheath cell (BSC) and they exhibit dimorphism related to the differential energy requirements ( Sedelnikova et al., 2024 ).

WebPlastid number and morphology vary dramatically between cell types and at different developmental stages. Furthermore, in C4 plants such as maize, chloroplast ultrastructure and biochemical functions are specialized in mesophyll and bundle sheath cells, which differentiate acropetally from the proplastid form in the leaf base.
