+*Expression analyses of flowering time genes in wild-type and lvp1 mutants revealed that Early heading date1, but not Heading date1, are misregulated in lvp1 mutants. In addition, the double mutant of lvp1 with photoperiod sensitivity5 (se5) flowered later than the se5 single mutant, indicating that lvp1 delays flowering time irrespective of photoperiod<ref name="ref1" />.
 *despite of their close chromosomal locations and high degree of similarity, SDG724 specifically affects H3K36me2/3 levels at the RFT1, but not the Hd3alocus. In addition, H3K36me2/3 levels at the Ehd1locus were also found to be unchanged in lvp1 plants, even though its expression was downregulated in lvp1 compared with wild-type plants (Figure 6). At all the loci examined, H3K4me3 levels were not significantly different be-tween lvp1 mutant and wild-type plants, which demonstrated aspecific relationship between SDG724 and H3K36 methylation.<ref name="ref1" />.
