Orchestration of development by the bifunctional transcription factor, APETALA2

(Submitter supplied) The emerging picture of transcriptional regulation is one of unexpected complexity. It is now clear that single transcription factors control hundreds, if not thousands, of direct targets by binding their genomic loci, but it is not understood how many of these are major players and how many are supporting cast. To address this, we leverage a well-characterized developmental network in Arabidopsis and map genome-wide binding of related proteins in multiple tissues. more...

Target genes of AGAMOUS during early flower development in Arabidopsis

(Submitter supplied) Floral organs, whose identity is determined by specific combinations of homeotic genes, originate from a group of undifferentiated cells called the floral meristem. In Arabidopsis, the homeotic gene AGAMOUS (AG) terminates meristem activity and promotes development of stamens and carpels. To understand the program of gene expression activated by AG, we followed genome-wide expression during early stamen and carpel development. more...

TOP1α functions on nucleosome density

(Submitter supplied) DNA topoisomerases release supercoils in DNA introduced during replication or transcription. How DNA topoisomerases impact transcription in the context of eukaryotic chromatin is poorly understood. In this study, using a floral stem cell model in Arabidopsis, we uncovered a role of TOP1α in Polycomb Group (PcG) protein-mediated histone lysine 27 trimethylation at, and transcriptional repression of, the stem cell maintenance gene WUSCHEL (WUS). more...

Differential gene expression at shoot apices between Wild Type and vip3-1-null allele

(Submitter supplied) The aim of this study was to evaluate gene expression defects at the shoot apical meristem and young flower meristems of the vip3-1 null allele. VIP3 belongs to polymerase II-associated factor 1 complex (Paf1c), which is involved in several RNA polymerase II-dependent transcriptional processes. Arabidopsis vip3 mutants exhibit phylotactic defects and strong floral indeterminacy phenotypes.

Gene expression analysis of the inflorescence of knu-1 and crc-1 knu-1

(Submitter supplied) Analyis gene expression in crc-1 knu-1 compared with knu-1 Initiation of the carpel primordia is marked by the termination of floral stem cells. Although genetic evidences have suggested that the YABBY gene CRABS CLAW (CRC) regulates the development of carpel, as well as the floral meristem determinacy as a target of the homeotic protein AGAMOUS, the underlying mechanism remains unclear. Here we show that the tetraspanin-encoding gene TONADO2 (TRN2) and the auxin biosynthesis gene YUCCA4 (YUC4) act as downstream targets of CRC.

Identification of WUSCHEL direct targets.

(Submitter supplied) Cell-cell communication is critical for stem cell maintenance. Shoot apical meristem (SAM) located at the shoot tip harbors stem cells within the central zone (CZ). Their progeny differentiate in the adjacent peripheral zone (PZ). WUSCHEL (WUS) is a homeodomain transcription factor produced in a few cells of the organizing center (OC), located beneath the CZ. It has been shown to specify stem cell fate and also activate CLAVATA3 (CLV3) expression in cells of the CZ. more...

Identification of genes regulated by the MADS transcription factor (TF), SEPALLATA3, in the context of the double sep1sep2 and triple sep1sep2sep3 mutant background, by RNA-Seq analysis

(Submitter supplied) These analyses allowed the identification of more than 2000 genes regulated by the MADS TF, SEPALLATA3 (SEP3). Although the involvement of SEP3 in all flower organ development is well established, the single sep3 mutant shows no flower phenotype, due to redundancy with other SEPALLATA genes. The triple mutant, sep1sep2sep3, shows no floral organ development except sepals, while the sep1sep2 mutant showed characteristic WT flower with, from the outer to the inner whorl of the flower, 4 sepals, 4 petals, 6 stamens and one gynoecium. more...

Genome-wide binding of SEPALLATA3 (SEP3) and AGAMOUS (AG) complexes determined by sequential DNA-affinity purification sequencing

(Submitter supplied) In this study, we compare the DNA binding specifify and affinity of SEPALLATA3 and AGAMOUS complexes The MADS transcription factors, SEPALLATA3 (SEP3) and AGAMOUS (AG), are required for floral organ identity and determinacy of the floral meristem in Arabidopsis. Dimerization is obligatory for their DNA binding, however SEP3 and SEP3-AG also form tetrameric complexes. The goal of this study is to understand how homo and hetero-dimerization and tetramerization of MADS TFs affect genome-wide DNA-binding patterns. more...

sequential DNA affinity purification sequencing (seq-DAP-seq) data of MADS SEP3-AG tetramerization mutants.

(Submitter supplied) The MADS genes encode transcription factors (TF) that act as master regulators of plant reproduction and flower development. The SEPALLATA (SEP) MADS subfamily is not only absolutely required for the development of floral organs, but also plays roles in inflorescence architecture and determinacy of the floral meristem. The SEPs act as organizers of MADS complexes and are able to form both heterodimers and heterotetramers in vitro. more...
