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 ...
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]
In rice, photoperiodic response is slightly more complex and is controlled by the florigen genes Rice Flowering locus T 1 (RFT1) and Heading date 3 a (Hd3a). Hd3a, is a homolog of flowering locus t and, when no longer repressed, activates flowering by directing modification of DNA at the shoot apical meristem with florigen.
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 ...
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.

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.
The cytokinin zeatin is named after the genus of corn, Zea.. Cytokinins (CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots.
"Na Na Na (Na Na Na Na Na Na Na Na Na)" has been met with generally positive critical enthusiasm. Spin ' s William Goldman described "Na Na Na" as an "in-your-face punk anthem with blistering guitar leads, an epic breakdown, and Gerard Way's sneering delivery", and added, "it's classic MCR and it's all hinged on an unforgettable, hockey-arena ...
