Figure 5.
(A) Western blot analyses of Rubisco large (LSU) and small (SSU) subunit, as well as (B) SUMO conjugates extracted from leaves of WT BIG8 and mutant BIG8-1 plants under well-watered (Day 0) and after exposure to water deficit stress (Day 7, 14, 21 PWS). Each lane contains 20 μg protein. The proteins were transferred to a nitrocellulose membrane and probed with polyclonal IgG raised against LSU and SSU (1:7000 dilution); while in the case of the SUMO conjugates with a monoclonal IgG raised against SUMO1 (1:10,000 dilution). M1–M3 represents result from three independent mutant plants.
