Genetic interaction of REV with WRKY53. (A) Rosette leaves of 6- and 7-week-old representative plants were sorted according to their age; whole rosettes were also photographed upside down to visualize the older leaves. (B) For a quantitative evaluation of leaf senescence, plants were harvested in a weekly rhythm and leaves of at least six plants were categorized into four groups according to their leaf color: (1) ‘green’; (2) leaves starting to become yellow from the tip as ‘yellow-green’; (3) completely yellow leaves as ‘yellow’; and (4) dry and/or brown leaves as ‘brown/dry’. The percentages of each group with respect to total leaf numbers are presented. Error bars indicate s.d. Student's t-test was performed comparing leaf counts of wrky53, rev5 and rev5wrky53 with Col-0 numbers, *P<0.05, **P<0.005, ***P<0.0005. n=7-15.
