The reviewer is correct in stating that Figure 1 may invite the conclusion that intron 1 does not fully account for basal FLMb levels. However, as we used transgenic lines for this analysis we suggest that no conclusions about the basal expression levels of native FLMb nor FLMd can be drawn from this analysis. Nevertheless, the relative change of transcript levels in response to changing temperature can be detected and compared to the WT construct, which is the main aim of this analysis. To avoid any misunderstandings, we normalized the transcript levels measured at 21°C to “1” and provided an improved description in the legend.
