   What is a CONSTANS-like protein?

   • [ Google Scholar] [ CrossRef] [ PubMed] Sng, N.J.; Kolaczkowski, B.; Ferl, R.J.; Paul, A.-L. A member of the CONSTANS-Like protein family is a putative regulator of reactive oxygen species homeostasis and spaceflight physiological adaptation.

   How does a Constans protein regulate the onset of flowering?

   • CONSTANS is an evolutionarily-conserved central component of the genetic pathway that controls the onset of flowering in response to daylength. However, the specific biochemical mechanism by which the CONSTANS protein regulates the expression of its target genes remains largely unknown.

   Is Constans A B-box protein?

   • CONSTANS is a member of the B-box family, which comprises a large subfamily of zinc finger proteins that contain one or more B-box domains with specialized tertiary structures that are stabilized by binding zinc ions ( Klug & Schwabe, 1995 ).

   Does the CONSTANS (CO) protein have a CCT motif?

   • The CONSTANS (CO) protein contains an activation domain, and neither the CCT motif nor B-boxes are required for transcriptional activation. (a) Schematic diagram of effector and reporter genes. B-boxes in the CO protein are labeled as B1 and B2.
