C4-CAM photosynthesis transition in plants

C4 and CAM (Crassulacean Acid Metabolism) photosynthesis are two specialized pathways that enable plants to efficiently utilize CO? in arid environments. C4 photosynthesis involves the initial fixation of CO? into a four-carbon compound, facilitating enhanced carbon concentration in bundle sheath cells, while CAM plants take up CO? at night and store it for use during the day. Some species can transition between these pathways depending on environmental conditions, showcasing remarkable metabolic flexibility. This transition is regulated by a network of genes and environmental cues, enabling plants to optimize photosynthesis and water use efficiency. Understanding these adaptations is vital for developing crops that can thrive in challenging climates.
