GenomicsRegulatory Modules Controlling Maize Inflorescence Architecture: ChIP-seq data
In this study we investigated the developmental dynamics of genes targeted in vivo by the transcription factor RAMOSA1, a key regulator of determinacy, and revealed potential mechanisms for repressing branches in distinct stem cell populations in developing maize inflorescences. To identify targets...

TranscriptomicsFASCIATED EAR4 encodes a bZIP transcription factor that controls shoot meristem size in maize
fasciated ear4 (fea4) is a semi-dwarfed mutant with fasciated ears and tassels, and greatly enlarged vegetative and inflorescence meristems. Chromatin Immunoprecipitation-sequencing (ChIP-seq) and expression profiling by RNA-seq suggest that fea4 is required to regulate the auxin response and leaf ...

TranscriptomicsRegulatory Modules Controlling Maize Inflorescence Architecture: mRNA-seq data
In this study we used the maize (Zea mays) inflorescence to investigate gene networks that modulate determinacy, specifically the decision to allow branch growth. We characterized developmental transitions by associating spatiotemporal expression profiles with morphological changes resulting from g...

TranscriptomicsDigital gene expression profiling for maize development - 2mm ear libraries, B73 vs. ramosa3 mutant
Genome-wide expression signatures detect specific perturbations in developmental programs and contribute to functional resolution of key regulatory networks. In maize (Zea mays) inflorescences, mutations in the RAMOSA (RA) genes affect determinacy of axillary meristems and thus alter branching patt...
