TL;DR: It is shown that expression of CONSTANS (CO), a gene that accelerates flowering in response to long days, is modulated by the circadian clock and day length, suggesting mechanisms by which day length regulates flowering time.

TL;DR: Double mutants were constructed containing co and mutations affecting gibberellic acid responses, meristem identity, or phytochrome function, and their phenotypes suggested a model for the role of CO in promoting flowering.

TL;DR: It is shown that CONSTANS is a member of an Arabidopsis gene family that comprises 16 other members, and analysis of seven classical co mutant alleles demonstrated that the mutations all occur within either the zinc finger region or the CCT domain, confirming that the two regions of homology are important for CO function.

TL;DR: It is demonstrated that alcR-mediated expression occurs throughout the plant in a highly responsive manner, and optimal strategies for utilizing the alc system in A. thaliana are described.

TL;DR: The BnCOa1 allele was shown to complement the co-2 mutation in Arabidopsis in a dosage-dependent manner causing earlier flowering than in wild type under both long- and short-day conditions.
