Sep 11,  · The Arabidopsis ABC genes function in discrete domains; AP1 and AP2 are A class genes (red), the products of which act in combination with other factors to countermand the activity of the AG C class gene (yellow) in the first and second whorls, while AG inhibits the function of the A class genes in the third and fourth pulleysmarine.com by: 9. rows · Each NBF contains Walker A and B boxes separated by an ABC signature motif. ABC proteins also contain two or three hydrophobic integral membrane domains each of which contains four to six transmembrane-helices. ABC Model of Flower Development | Plants. In the whorl 1 class A genes when expressed induce the development of sepals. The interaction between class A and class B genes induce the development of petals in the whorl 2. Stamens are formed in the whorl 3 as a result of interaction between class B and class C genes.

Genes exhibiting type-B function. As discussed above, the floral organs of eudicotyledonous angiosperms are arranged in 4 different verticils, containing the sepals, petals, stamen and carpels. The ABC model states that the identity of these organs is determined by . rows · Each NBF contains Walker A and B boxes separated by an ABC signature motif. ABC proteins also contain two or three hydrophobic integral membrane domains each of which contains four to six transmembrane-helices. Through synteny, we have identified the Arabidopsis Sw ortholog. Mutagenesis has revealed that this ortholog is associated with seed length variation and fatty acid deposition in seeds, raising the possibility that the ABC transporter may modulate seed size variation in other species. Transcription studies show that the ABC transporter gene. ABC Model of Flower Development | Plants. In the whorl 1 class A genes when expressed induce the development of sepals. The interaction between class A and class B genes induce the development of petals in the whorl 2. Stamens are formed in the whorl 3 as a result of interaction between class B and class C genes.

    Just that is necessary. I know, that together we can come to a right answer.
