The 41 pages that link to C4 carbon fixation, each with the reason it gives.
PhotosynthesisBroader topic: It is a photosynthetic adaptation that reduces photorespiration in hot, bright environments.
MioceneRelated: Its expansion among grasses is associated with changing Miocene climates and atmospheric conditions.
ChloroplastCompared with: C4 plants reorganize carbon delivery to chloroplasts, reducing photorespiration in hot conditions.
MaizeRelated: Maize uses C4 photosynthesis, supporting high productivity in heat and bright sunlight.
SugarcaneRelated: This photosynthetic pathway helps sugarcane grow efficiently in tropical sunlight.
StomataCompared with: Its carbon-concentrating mechanism can reduce water costs compared with C3 plants.
Calvin cycleCompared with: It limits photorespiration by delivering carbon dioxide to the Calvin cycle in specialized cells.
PoaceaeRelated: Its repeated evolution in grasses helps explain their success in hot, open environments.
Crassulacean acid metabolismCompared with: Like CAM, it uses phosphoenolpyruvate carboxylase to concentrate carbon dioxide, but separates steps across cells.
African savannaRelated: Many savanna grasses use this pathway, which performs well in heat and bright light.
SteppeRelated: Some steppe grasses use this pathway to cope with warmth and seasonal water stress.
AcaciaCompared with: It is a specialized carbon-fixation pathway, unlike the pathway used by acacias.
CAM photosynthesisCompared with: C4 and CAM share four-carbon intermediates but separate carbon concentration in different ways.
C3 carbon fixationCompared with: C4 plants concentrate carbon dioxide near Rubisco, reducing photorespiration.
SorghumRelated: Sorghum uses this pathway to photosynthesize efficiently in warm, bright conditions.
PhotorespirationCompared with: This adaptation suppresses photorespiration, especially in hot, bright environments.
Tropical savannaRelated: Many tropical savanna grasses use this pathway to grow efficiently in heat and seasonal drought.
Paranthropus boiseiRelated: Its isotope signature suggests substantial reliance on foods from C4 ecosystems.
RuBisCOCompared with: It reduces RuBisCO’s exposure to oxygen in hot, bright environments.
QuinoaRelated: Quinoa uses C4 photosynthesis, which can support productivity under bright, warm conditions.
AmaranthaceaeRelated: C4 photosynthesis occurs in several Amaranthaceae lineages, especially in hot, dry environments.
MalateRelated: C4 plants produce malate as a transport form of fixed carbon.
MilletRelated: Most major millet crops use C4 photosynthesis, which can improve water-use efficiency in heat.
PoalesRelated: Several grass lineages use this pathway to photosynthesize efficiently in hot, bright environments.
Temperate grasslandsRelated: Many warm-season grasses use this pathway to thrive during hot, sunny summers.
ConvolvulaceaeCompared with: It contrasts with the C3 pathway used by sweet potato and most other family members.
Melvin CalvinCompared with: C4 plants add a carbon-concentrating mechanism around the cycle Calvin mapped.
Phragmites australisRelated: As a C3 grass, common reed lacks this pathway, which helps distinguish its photosynthetic strategy from many warm-climate grasses.
Biological carbon fixationBroader topic: It concentrates carbon dioxide around Rubisco, reducing photorespiration in hot, dry conditions.
Columbian mammothRelated: Carbon isotopes in Columbian mammoth remains indicate substantial consumption of C4 grasses.
CommelinaCompared with: Unlike many tropical grasses, Commelina species generally use the C3 pathway rather than C4 photosynthesis.
DigitariaRelated: Several Digitaria grasses use C4 photosynthesis, an adaptation common among warm-climate grasses.
EcophysiologyBroader topic: It illustrates a plant adaptation that can improve carbon gain in hot, bright environments.
Finger milletRelated: Its C4 photosynthesis supports productive growth in hot, sunny environments.
Mesophyll cellsCompared with: In C4 plants, mesophyll cells capture carbon dioxide and pass it to specialized bundle-sheath cells.
AizoaceaeCompared with: It offers a contrasting water-saving strategy to the CAM pathway found in some family members.
AxonopusRelated: Many tropical grasses use this pathway, which suits warm, bright growing conditions.
Plant metabolismBroader topic: Its adaptations can improve carbon gain in hot, bright environments.
Plant Physiological PhenomenaCompared with: It reduces photorespiration and contrasts with the more widespread C3 pathway.
Tropical and subtropical grasslandsRelated: Many tropical grasses use this pathway to thrive in hot, seasonally dry environments.
ZoysiaRelated: This pathway supports zoysia’s growth in warm, sunny conditions.
