1) The authors state that “The presence of intron 1 is sufficient to restore the basal expression of FLM” – while it does restore expression levels to detectable levels, the expression level of the β splice variant at 15°C is considerably lower than the WT, whereas the FLMδ levels are similar the WT at this temperature. This would indicate that intron 1 alone cannot fully account for basal levels of FLM β.
