LEAFY controls floral meristem identity in Arabidopsis
It is demonstrated that LEAFY is the Arabidopsis homolog of the FLORICAULA gene, which controls floral meristem identity in the distantly related species Antirrhinum majus. Expand
Distinct roles of CONSTANS target genes in reproductive development of Arabidopsis.
Four early target genes of CO were identified using a steroid-inducible version of the protein to define common components of distinct flowering-time pathways. Expand
Activation tagging in Arabidopsis.
Activation tagging using T-DNA vectors that contain multimerized transcriptional enhancers from the cauliflower mosaic virus (CaMV) 35S gene has been applied to Arabidopsis plants, and it is shown that overexpressed genes are almost always found immediately adjacent to the inserted CaMV 35S enhancers.

B and C floral organ identity functions require SEPALLATA MADS-box genes
This simple model provides a conceptual framework for explaining how the individual and combined activities of the ABC genes produce the four organ types of the typical eudicot flower. Expand
Molecular characterization of the Arabidopsis floral homeotic gene APETALA1
Cloned the APETALA1 gene is cloned and it is shown that it encodes a putative transcription factor that contains a MADS-domain2 that is uniformly expressed in young flower primordia, and later becomes localized to sepals and petals. Expand

The agamous gene probably encodes a transcription factor that regulates genes determining stamen and carpel development in wild-type flowers. Expand
Assessing the redundancy of MADS-box genes during carpel and ovule development
It is shown that the SHP genes are responsible for AG-independent carpel development and all four members of the AG clade are required for specifying the identity of ovules, the landmark invention during the course of vascular plant evolution that enabled seed plants to become the most successful group of land plants. Expand
Redundant regulation of meristem identity and plant architecture by FRUITFULL, APETALA1 and CAULIFLOWER.
This work finds that mutations in the FRUITFULL (FUL) MADS-box gene, when combined with mutations in AP1 and CAL, lead to a dramatic non-flowering phenotype in which plants continuously elaborate leafy shoots in place of flowers. Expand
SHATTERPROOF MADS-box genes control seed dispersal in Arabidopsis

It is shown that the closely related SHATTERPROOF (SHP1) and SHP2 ) MADS-box genes are required for fruit dehiscence in Arabidopsis, and that further analysis of the molecular events underlying fruit deHiscence may allow genetic manipulation of pod shatter in crop plants. Expand
The SEP4 Gene of Arabidopsis thaliana Functions in Floral Organ and Meristem Identity

- 9 November 2004
The SEP4 gene is characterized, which shares extensive sequence similarity to and an overlapping expression pattern with the other SEP genes, and it is found that it contributes to the development of petals, stamens, and carpels in addition to sepals and that it plays an important role in meristem identity.
