Bundle sheath suberisation is required for C4 photosynthesis in a Setaria viridis mutant (Nature Comms)
An efficient C4 photosynthetic pathway relies on the coordination between the biochemical carbon concentration mechanism that secures high rates of C4 acid flow into the bundle sheath (BS) and anatomical modifications that minimize CO2 leakage out of the BS cells. Suberin deposition in BS cell walls has been believed to seal BS cells against leakiness of CO2 […]
