Isolation and Characterization of Soybean CONS Transcription Factor Promoters
Cons refers to constitutively-expressed, as described by M. Libault et.
al. (2008).
Is the following desciprion correct ?
The CO gene was originally defined by an allelic series of mutants that flower late in LD and do
not respond to photoperiod . CO has subsequently been shown to encode a transcription factor that
plays a central role in the photoperiod detection mechanism acting between the circadian clock and
genes controlling meristem identity. Griffiths et al. (2003) have defined the CO-like gene family
by the presence of two conserved domains: a Zn-finger region near the N-terminus that resembles
B-box domains and a region near the C-terminus called the CCT domain (Putterill et al., 1995).
Using this definition, Griffiths et al. (2003) have shown that CO is part of a 17-member gene
family in Arabidopsis that consists of three broad groups. Group I genes, which include CO, have
two Zn-finger B-boxes near the N- terminus . Group II genes have one B-box, and Group III genes
have one B-box and a second diverged Zn-finger. Mutants that affect CO function map to both the
B-box and the CCT domain.
