Florigen is a systemically mobile signal that is synthesized in leaves and the transported via the phloem to the shoot apical meristem (SAM) where it initiates flowering. [ 1 ] [ 5 ] : 488 In Arabidopsis , the FLOWERING LOCUS T ( FT ) genes encode for the flowering hormone and in rice the hormone is encoded by Hd3a genes thereby making these ...
The molecular interpretation of these signals is through the transmission of a complex signal known as florigen, which involves a variety of genes, including Constans, Flowering Locus C, and Flowering Locus T. Florigen is produced in the leaves in reproductively favorable conditions and acts in buds and growing tips to induce several different ...
Mikhail Khristoforovich Chailakhyan (Armenian: Միքայել Քրիստափորի Չայլախյան, Russian: Михаи́л Христофо́рович Чайлахя́н; 1902–1991) was a Soviet Armenian scientist who is widely known for proposing the existence of a universal plant hormone that is involved in flowering. [1]
The significance of Florigene's technology is the brand potential of its novel flower varieties - a blue rose is a marketer's dream. In 2004, after 20 years and A$45 million worth of exhaustive research and prolific patenting, Florigene and Suntory scientists announced to the world the development of the first rose in the pipeline to a true blue rose.

In Arabidopsis, flowering locus t is responsible for the production of florigen, which induces Turck_2008 in the shoot apical meristem, a special set of growth tissues, to establish flowering. [11] Homologs of the flowering genes exist in flowering plants, but the exact nature of how the genes respond to each mechanism might differ between species.
The original tree grew from a seed planted in 1932 on the property of John G. Kaiser of Fort Lauderdale, Florida. [1] Kaiser was known for growing hybrid mangos, [2] and later became the police chief as well as the clerk of the court for Ft. Lauderdale and later was a member of the executive committee of the Florida Mango Forum.
Another set of experiments with Arabidopsis thaliana testing genes in the plant hormone florigen, two genes FT and TSF (which are abbreviations for Flowering Locus T, and Twin Sister of FT) when knocked out, appear to affect lateral shoot in a negative fashion.
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
