CONSTANS ACTIVATES FLOWERING LOCUS. “The FT protein is a component of the mobile flowering signal ‘florigen’ that moves upon its expression in the vascular tissue of leaves to the shoot apex. The capability of CO to induce FT expression is counteracted by several regulators that repress FT through different mechanisms or pathways, thereby preventing precocious flowering.” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

THE CASCADE. “CO activates the expression of FLOWERING LOCUS T (FT), probably by binding to FT regulatory regions and by interacting with transcription factors of the NF-YB and NF-YC classes 11, 12, 13.” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

CONSTANS GENE. “CO codes for a zinc finger and CCT-domain-containing transcription factor that accumulates under long day conditions in leaves as a result of the combination of the rhythmic expression of CO mRNA and the stabilization of CO protein by light.” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

“LONG DAYS accelerate flowering via the photoperiodic (day length) pathway, which is mediated by CONSTANS (CO).” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

EPIGENETIC CUES. “In Arabidopsis, flowering in response to seasonal changes is controlled by the vernalization, photoperiod and ambient temperature pathways, which act coordinately with those that respond to endogenous and developmental cues: the autonomous, gibberellin and age-dependent pathways (see Figure 1).” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

FLORAL MERISTEM IDENTITY GENES. “We will describe the central role that AP1 plays in the transition from floral induction to flower formation by acting as a switch between these two developmental programs and constituting a hub in the corresponding network of regulatory genes.” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

GENERATIVE NODES. “Floral meristem identity genes code for transcription factors that are conserved across plant species and include Arabidopsis APETALA1 (AP1) (and paralogs) and LEAFY (LFY).” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn

FLOWERING TIME PATHWAYS. “Ultimately, all of these pathways converge on so-called floral meristem identity genes, which act by directing the meristems (or primordia) that form on the flanks of the inflorescence meristem to develop into flowers.” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn
