Time course of Rubisco activation during a transition from high light
to low light for 1 h and a return to high light in various plants.
The plants examined are the wild type (A), the
rca mutant (B), 43-kDa isoform
transformant of the rca mutant (C),
46-kDa isoform transformant of the rca mutant
(D), progeny of a cross between the 43- and 46-kDa
transformants (E), 46-kDa isoform transformant with a
C411A substitution (F), and 46-kDa isoform transformant
with C411Aand C392A substitutions (G). Data are the
means of two or three replicates.
