  2. Florigen - Wikipedia

    en.wikipedia.org/wiki/Florigen

    Florigen is regulated by the action of an antiflorigen. [15] Antiflorigens are hormones that are encoded by the same genes for florigen that work to counteract its function. [15] The antiflorigen in Arabidopsis is TERMINAL FLOWER1 (TFL1) [6] and in tomato it is SELF PRUNING (SP). [16]

  3. ABC model of flower development - Wikipedia

    en.wikipedia.org/wiki/ABC_model_of_flower...

    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.

  4. Epigenetics of plant growth and development - Wikipedia

    en.wikipedia.org/wiki/Epigenetics_of_Plant...

    In Arabidopsis, the gene CONSTANS responds to long day conditions and enables flowering when it stops repressing flowering locus t. [13] 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 ...

    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 ...

  6. Plant genetics - Wikipedia

    en.wikipedia.org/wiki/Plant_genetics

    An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.

  7. Gibberellin - Wikipedia

    en.wikipedia.org/wiki/Gibberellin

    The null alleles of the genes encoding CPS, KS, and KO result in GA-deficient Arabidopsis dwarves. [12] Multigene families encode the 2ODDs that catalyze the formation of GA 12 to bioactive GA 4. [8] AtGA3ox1 and AtGA3ox2, two of the four genes that encode GA3ox in Arabidopsis, affect vegetative development. [13]

    en.wikipedia.org/wiki/Karrikin

    [citation needed] The two genes, MORE AXILLARY GROWTH2 (MAX2) and KARRIKIN-INSENSITIVE2 (KAI2) are essential for understanding the actions of karrikins and were discovered in Arabidopsis mutants which failed to respond to karrikins. In rice, strigolactones interact with the F-box protein knowns as DWARF3 upon their hydrolysis by the DWARF14 ...

  9. Gene-for-gene relationship - Wikipedia

    en.wikipedia.org/wiki/Gene-for-gene_relationship

    One is a plant gene called the resistance gene. The other is a parasite gene called the avirulence (Avr) gene. Plants producing a specific R gene product are resistant towards a pathogen that produces the corresponding Avr gene product. [5] Gene-for-gene relationships are a widespread and very important aspect of plant disease resistance.
