Linked Claims

Claim 1evolutionary conservationsupports2013Source 1DOIPubMed

Ehd4 is highly conserved in the Oryza genus including wild and cultivated rice and has no homologs in other species.

Claim 2expression patternsupports2013Source 1DOIPubMed

Ehd4 expression is most active in young leaves and shows a diurnal expression pattern similar to Ehd1 under both short-day and long-day conditions.

Claim 3functional importancesupports2013Source 1DOIPubMed

Ehd4 is a novel Oryza-genus-specific regulator of Ehd1 that plays an essential role in photoperiodic control of flowering time in rice.

Quoted textsource-backed
We conclude that Ehd4 is a novel Oryza-genus-specific regulator of Ehd1, and it plays an essential role in photoperiodic control of flowering time in rice.
Claim 4gene regulationsupports2013Source 1DOIPubMed

Ehd4 up-regulates Hd3a and RFT1 expression through Ehd1.

Quoted textsource-backed
We show that Ehd4 up-regulates the expression of the "florigen" genes Hd3a and RFT1 through Ehd1
Claim 5molecular activitysupports2013Source 1DOIPubMed

Ehd4 binds nucleic acids in vitro and transactivates transcription in yeast, suggesting it functions as a transcriptional regulator.
