Other claims from this paper (4)
- Intervention effect Initial Rubisco activity decreased to half in severely stressed leaves of Paspalum dilatatum.
- Intervention effect The percentage of Rubisco activation decreased sharply under stress.
- Mechanism The authors suggest that lower initial activities indicate a lower carbamylation status of the enzyme in stressed leaves.
- Mechanism The authors suggest the increase of maximal Rubisco activity points to de novo synthesis of the enzyme, a hypothesis still to be checked.
