“The nine PRO2+/INT6+ haplotype combinations included in our transgenic experiments represent 69% of the world-wide PRO2+/INT6+ variation (Figure 8—figure supplement 1A). […] Bearing these possible genetic and environmental interferences in mind, we regard the detected effect of FLM-ß on flowering (21%) in cool (15°C) temperatures as considerable and suggest that it is rather an underestimation.”
