OsMADS1 Interacts with OsMADS22 and OsYABBY5 to Regulate Floral Organ and Meristem Identity in Rice [PDF]
The development of rice flowers and panicles critically affects grain yield and quality. LEAFY HULL STERILE1/OsMADS1, a grass-specific SEPALLATA-like MADS-box transcription factor, is essential for rice floral development and floral meristem activity ...

The Roles of Floral Organ Genes in Regulating Rosaceae Fruit Development
The function of floral organ identity genes, APETALA1/2/3, PISTILLATA, AGAMOUS, and SEPALLATA1/2/3, in flower development is highly conserved across angiosperms. Emerging evidence shows that these genes also play important roles in the development of the

Spontaneous homeotic mutants and genetic control of floral organ identity in a ranunculid
The regulation of floral organ identity was investigated using a forward genetic approach in five floral homeotic mutants of Thalictrum, a noncore eudicot. We hypothesized that these mutants carry defects in the floral patterning genes.

Transcriptomic insights into unisexual flower development in Cannabis sativa: conserved MADS-box networks and divergent developmental programs [PDF]
Background Cannabis sativa, a dioecious species characterized by striking sexual dimorphism and exceptional sexual plasticity, presents a powerful model for exploring floral development and the evolution of dioecy. The unique male and female flowers each

The biphasic floral transition in Arabidopsis thaliana involves many redundant intersecting regulatory networks. The related AP2 transcription factors DORNRÖSCHEN (DRN), DORNRÖSCHEN-LIKE (DRNL), and PUCHI individually execute well-characterized functions

Sub-functionalization to ovule development following duplication of a floral organ identity gene.
Gene duplications result in paralogs that may be maintained due to the gain of novel functions (neo-functionalization) or the partitioning of ancestral function (sub-functionalization). Plant genomes are especially prone to duplication; paralogs are particularly widespread in the floral MADS box transcription factors that control organ identity through

Control of Reproductive Floral Organ Identity Specification in Arabidopsis by the C Function Regulator AGAMOUS[C][W] [PDF]
AbstractThe floral organ identity factor AGAMOUS (AG) is a key regulator of Arabidopsis thaliana flower development, where it is involved in the formation of the reproductive floral organs as well as in the control of meristem determinacy. To obtain insights into how AG specifies organ fate, we determined the genes and processes acting downstream of ...

‘Organ’ising Floral Organ Development
Flowers are plant structures characteristic of the phylum Angiosperms composed of organs thought to have emerged from homologous structures to leaves in order to specialize in a distinctive function: reproduction.

AGAMOUS mediates timing of guard cell formation during gynoecium development.
In Arabidopsis thaliana, stomata are composed of two guard cells that control the aperture of a central pore to facilitate gas exchange between the plant and its environment, which is particularly important during photosynthesis.

Floral organ development is fundamental to sexual reproduction in angiosperms. Many key floral regulators (most of which are transcription factors) have been identified and shown to modulate floral meristem determinacy and floral organ identity, but not ...
