The genome of the domesticated apple (Malus × domestica Borkh.)
It is shown that a relatively recent (>50 million years ago) genome-wide duplication has resulted in the transition from nine ancestral chromosomes to 17 chromosomes in the Pyreae, which partly support the monophyly of the ancestral paleohexaploidy of eudicots.
Molecular and phylogenetic analyses of the complete MADS-box transcription factor family in Arabidopsis: new openings to the MADS world.
This study provides a solid base for functional genomics studies into this important family of plant regulatory genes, including the poorly characterized group of M-type MADS-box proteins.
MADS-Box Protein Complexes Control Carpel and Ovule Development in Arabidopsis Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.015123.
It is shown that ectopic expression of either the STK or SHP gene is sufficient to induce the transformation of sepals into carpeloid organs bearing ovules and that the SEP proteins, known to form multimeric complexes in the control of flower organ identity, also form complexes to control normal ovule development.
AGL24, SHORT VEGETATIVE PHASE, and APETALA1 Redundantly Control AGAMOUS during Early Stages of Flower Development in Arabidopsis[W]
Genetic evidence for the role of AP1 in the recruitment of the SEU-LUG repressor complex for the regulation of AGAMOUS is provided by showing that the floral phenotype in the ap1 agl24 svp triple mutant is significantly enhanced.
Comprehensive Interaction Map of the Arabidopsis MADS Box Transcription Factorsw⃞
A comprehensive plant protein–protein interactome map of nearly all members of the Arabidopsis thaliana MADS box transcription factor family is presented and a model is proposed that integrates the floral induction and floral organ formation networks based on the interactions between the proteins involved.
Multiple AGAMOUS Homologs from Cucumber and Petunia Differ in Their Ability to Induce Reproductive Organ Fate
It is demonstrated that in petunia and cucumber, multiple AG homologs exist, although they differ in their ability to induce reproductive organ fate, and there is no additive effect of concerted expression.

It is shown that the osmads13 mutant is female sterile and that ovules are converted into carpelloid structures, suggesting that the D-lineage gene OsMADS21 has lost its ability to determine ovule identity.
The Arabidopsis floral meristem identity genes AP1, AGL24 and SVP directly repress class B and C floral homeotic genes.

It is shown that the distantly related suppressor of overexpression of CO 1 (SOC1) MADS box gene can complement for the loss of AGL24 and SVP activity; however, under normal conditions, this transcription factor does not play a role during the early stages of flower development.
BASIC PENTACYSTEINE1, a GA Binding Protein That Induces Conformational Changes in the Regulatory Region of the Homeotic Arabidopsis Gene SEEDSTICK
This work identified BASIC PENTACYSTEINE1 (BPC1) as a regulator of the homeotic Arabidopsis thaliana gene SEEDSTICK (STK), which controls ovule identity, and characterized its mechanism of action.
Ovule-specific MADS-box proteins have conserved protein-protein interactions in monocot and dicot plants
It is shown that ectopic expression of OsMADS13 in rice and Arabidopsis does not result in the formation of ectopic ovule formation and the evolutionary conservation of the MADS-box protein partners of these ovule-specific factors was confirmed.
