Meet the protein

FLC participates in flowering-time regulation in Arabidopsis thaliana. The retained UniProt annotation describes it as a putative transcription factor that delays flowering by repressing SOC1. This connects whole-plant development with gene regulation. The selected object is protein product Q9S7Q7; its gene, transcript and abundance in a particular plant are separate research objects.

FLC is discussed in relation to the FRIGIDA, autonomous and vernalization pathways. The entry also gives a temperature condition from an individual study and cites the supporting work. Those conditions cannot automatically be extended to every plant or climate. Compare the annotation with the linked FLC lesson while preserving genotype, experimental conditions and source version.

Connect a regulator to a developmental outcome

The retained FLC annotation connects a putative transcription factor with repression of SOC1 and delayed flowering. This describes a regulatory link: a protein affects the expression of another gene, and the developmental consequence is considered at plant level. The gene-regulation lesson asks what was changed and what was measured in a specific experiment. Protein identity, RNA abundance and flowering time are separate entries in that experiment note; one cannot substitute for another. The word “putative” in the retained annotation remains part of its scope.

    Source text
    Putative transcription factor that seems to play a central role in the regulation of flowering time in the late-flowering phenotype by interacting with 'FRIGIDA', the autonomous and the vernalization flowering pathways. Inhibits flowering by repressing 'SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1'. At elevated temperatures (e.g. 29 degrees Celsius), maintained at high levels in a JMJ30/JMJ32-dependent manner to prevent extreme precocious flowering (PubMed:25267112)
