Genetic control of the flowering

摘要

A flowering characteristic of a plant, particularly the timing of flowering, is controlled by the expression of the Late Elongated Hypocotyl (LHY) gene of Arabidopsis thaliana or a mutant, variant, allele, derivative, or homologue thereof. Over-expression may be used to delay flowering in a transgenic plant. The promoter of the gene regulates transcription in accordance with the circadian rhythm and may be used to control expression of genes whose products are only required or desired at certain times of the day.
