Architecture of floral branch systems in maize and related grasses
Jul 24, 2005 · Here we report the isolation of the maize ramosa1 gene and show that it controls inflorescence architecture. Through its expression in a boundary domain near the nascent …
Branching Out: The ramosa Pathway and the Evolution of Grass ...
Double mutants between ra2 and a weak allele of ra1 have a greatly enhanced ear phenotype, suggesting that ra2 and ra1 act in the same pathway. Convincing evidence was provided by …
ramosa2 Encodes a LATERAL ORGAN BOUNDARY Domain Protein …
To find out whether ra2 and ra1 expression overlap, we performed in situ hybridization of ra1 in wild-type tassels using the probe described by Vollbrecht et al. (2005). The onset of ra1 …
Evidence of selection at the ramosa1 locus during maize ... - PubMed
Genes thought to have been selected upon during the domestication of crops are commonly known as domestication loci. The ramosa1 (ra1) gene encodes a putative transcription factor …
A trehalose metabolic enzyme controls inflorescence ... - Nature
May 11, 2006 · Genetic and molecular data indicate that RA3 functions through the predicted transcriptional regulator RAMOSA1 (RA1) 5. We propose that RA3 regulates inflorescence …

Regulatory modules controlling maize inflorescence architecture
Developmental dynamics of genes targeted in vivo by the transcription factor RAMOSA1, a key regulator of determinacy, revealed potential mechanisms for repressing branches in distinct …
Interspecies transfer of RAMOSA1 orthologs and promoter cis …
Feb 12, 2023 · Grass inflorescences support floral structures that each bear a single grain, where variation in branch architecture directly impacts yield. The maize (Zea mays) RAMOSA1 …
