Comment Fl1 (Hd1) is a homolog of CONSTANS gene (At5g15840) from Arabidopsis and encodes a protein with a zinc finger domain. The major gene controlling photoperiodic sensitivity, Se1, is allelic to Hd1. The same amount of Hd1 mRNA detected under both SD and LD conditions suggests that the gene is bifunctional under short-day (SD) and long-day (LD) conditions, promoting heading under SD conditions and inhibiting it under LD conditions. As compared to Arabidopsis, rice is a short-day plant and its heading is promoted by short photoperiods.
Photoperiod sensitivity. Related to heading date and maturity in rice. Strong photoperiodic sensitivity is dominant over insensitivity. (Imported from Gene GR:0060860)
