Other claims from this paper (14)
- Observation Leaf epidermis had less than 10 mM calcium and mesophyll more than 60 mM.
- Observation CAX1, ACA4 and ACA11 were preferentially expressed in calcium-rich mesophyll.
- Intervention effect Only the double loss of CAX1 and CAX3 reduced mesophyll calcium.
- Intervention effect CAX3 was ectopically expressed in leaves after CAX1 knockout.
- Association Reduced mesophyll calcium accumulation reduced cell-wall extensibility.
- Association Reduced mesophyll calcium accumulation reduced transpiration.
- Association Reduced mesophyll calcium accumulation reduced CO2 assimilation.
- Association Reduced mesophyll calcium accumulation reduced leaf growth rate.
- Association Reduced mesophyll calcium accumulation increased transcript abundance of other calcium transporter genes.
- Association Reduced mesophyll calcium accumulation altered expression of cell-wall-modifying proteins.
- Association Reduced mesophyll calcium accumulation increased pectin concentration.
- Association Reduced mesophyll calcium accumulation increased cell-wall thickness.
- Observation Apoplastic free calcium was threefold greater in cax1/cax3 than wild type.
- Mechanism Altered apoplastic free calcium explains the mutant phenotypes.
