The expression of genes related to senescence are altered in the nup98a-1 nup98b-1 double mutant. Up-regulated genes both at dawn (ZT0) and dusk (ZT16) (a) or at either dawn (ZT0) or dusk (ZT16) (b). c: Dawn-regulated genes at dawn (ZT0) and/or dusk (ZT16). d: Up-regulated or dawn-regulated genes at dawn (ZT0) and dusk (ZT16), respectively. e: Constitutively expressed genes. The 14-day-old seedlings of the nup98a-1 nup98b-1 double mutant and wild type plants in long day conditions were harvested at ZT0 and ZT16. All RT-PCR measurements were repeated at least three times, each time in triplicate. All RT-PCR gene transcript measurements were normalized to the control TIP41 (At4g34270) and shown as a relative value. Student’s t test was employed for statistical analysis. An * indicates measurements that were significantly (*P < 0.05 or **P < 0.01) different from the control. Error bars indicate ± SD of the mean
