Diversification of Floral Homeotic Gene Function

چکیده
shown to also be required for specifying petal, stamen, and carpel identities, adding another layer of complexity to the ABC model (Pelaz, et al., 2000) (Fig. 1). These MADS-box gene products form ternary and quaternary complexes which could explain, at the molecular level, how these transcription factors coordinate their functions (Honma and Goto, 2001; Pelaz, et al., 2001). The expression patterns of all of these genes, with the exception of AP2 which is expressed ubiquitously throughout the flower, largely corresponds to their domains of action as postulated in the ABC model.

SEPALLATA gene diversification: brave new whorls.
SEPALLATA (SEP) genes form an integral part of models that outline the molecular basis of floral organ determination and are hypothesized to act as co-factors with ABCD floral homeotic genes in specifying different floral whorls. The four SEP genes in Arabidopsis function redundantly, but the extent to which SEP genes in other flowering plants function similarly is unknown. Using a recent 113-g...
متن کاملFunctional analyses of two tomato APETALA3 genes demonstrate diversification in their roles in regulating floral development.
The floral homeotic APETALA3 (AP3) gene in Arabidopsis thaliana encodes a MADS box transcription factor required for specifying petal and stamen identities. AP3 is a member of the euAP3 lineage, which arose by gene duplication coincident with radiation of the core eudicots. Although Arabidopsis lacks genes in the paralogous Tomato MADS box gene 6 (TM6) lineage, tomato (Solanum lycopersicum) pos...
متن کاملMolecular mechanisms underlying origin and diversification of the angiosperm flower.
BACKGROUND Understanding the mode and mechanisms of the evolution of the angiosperm flower is a long-standing and central problem of evolutionary biology and botany. It has essentially remained unsolved, however. In contrast, considerable progress has recently been made in our understanding of the genetic basis of flower development in some extant model species. The knowledge that accumulated t...
متن کاملFunctional diversification of the two C-class MADS box genes OSMADS3 and OSMADS58 in Oryza sativa.
The C-class MADS box gene AGAMOUS (AG) plays crucial roles in Arabidopsis thaliana development by regulating the organ identity of stamens and carpels, the repression of A-class genes, and floral meristem determinacy. To examine the conservation and diversification of C-class gene function in monocots, we analyzed two C-class genes in rice (Oryza sativa), OSMADS3 and OSMADS58, which may have ar...
متن کاملFunction of the apetala-1 gene during Arabidopsis floral development.
We have characterized the floral phenotypes produced by the recessive homeotic apetala 1-1 (ap1-1) mutation in Arabidopsis. Plants homozygous for this mutation display a homeotic conversion of sepsis into brachts and the concomitant formation of floral buds in the axil of each transformed sepal. In addition, these flowers lack petals. We show that the loss of petal phenotype is due to the failu...
