Intervention effect Down-regulation of SDG711 promoted flowering in long day.
Intervention effect Over-expression and down-regulation of SDG711 had no effect on flowering in short day.
Intervention effect Down-regulation of SDG718 delayed flowering in short day.
Intervention effect Down-regulation of SDG718 had no effect on flowering in long day.
Intervention effect Expression of SDG711 is induced by long day.
Intervention effect Expression of SDG718 is induced by short day.
Association SDG711 repressed OsLF in long day.
Association SDG718 repressed OsLF in short day.
Association Repression of OsLF led to a higher expression of Hd1.
Association Late flowering occurred in long day.
Association Early flowering occurred in short day.
Association SDG711 is involved in repression of Ehd1 in long day.
Mechanism SDG711 targets OsLF and Ehd1 loci to mediate gene repression through H3K27me3.
Mechanism PRC2-mediated epigenetic repression of gene expression is involved in accurate photoperiod control of rice flowering.

gain of function → more of the trait

The program reads each claim's manipulation and the direction of the trait, and from them the gene's role (gain and more, or loss and less, means it promotes the trait). Roles are read by program from each claim's wording. Pairs of papers on the same host, gene and trait were checked claim by claim by two model readers; a pair is marked checked only when both accept it. Gene layer v0.8, 21 trait classes.
