The fates of RNA splice variants. Steady-state levels of the β transcripts were determined by qRT-PCR in Col-0 plants after CHX treatments (left panels) and in the upf1-5 and upf3-1 mutants (right panels). Biological triplicates were averaged and statistically treated using Student t-test (*P < 0.01). Bars indicate standard error of the mean. A. The fates of PRR7β, PRR9β, and ZTLβ transcripts. B. The fates of TOC1β and ELF3β transcripts.
