Other claims from this paper (8)
- Intervention effect Calcium deficiency limited carrot cell growth.
- Intervention effect Control and calcium-deprived carrot cell walls yielded similar amounts of pectic fractions.
- Intervention effect Pectic fractions from calcium-deprived carrot cell walls had substantially less galacturonic acid.
- Intervention effect After 15 days, calcium-deprived carrot cells released galacturonic-acid-rich extracellular polysaccharides at twice the control rate.
- Observation The released polysaccharides were predominantly composed of arabinose, galactose and galacturonic acid.
- Intervention effect Calcium-deprived carrot cells secreted three times more extracellular proteins than normal cells.
- Intervention effect The medium polypeptide pattern differed between control and calcium-deprived carrot cells.
- Intervention effect Calcium deficiency greatly reduced α-l-arabinofuranosidase and β-galactosidase activities.
