Regulation of FLOWERING LOCUS T by a microRNA in Brachypodium distachyon.

The highly conserved florigen gene FLOWERING LOCUS T (FT) functions at the core of the flowering pathways. Extensive studies have examined the transcriptional regulation of FT; however, other layers of FT regulation remain unclear. Here, we identified miR5200 a Pooideae-specific microRNA that is expressed in leaves and targets Brachypodium distachyon FT orthologs for mRNA cleavage. miR5200 was ...

Small RNAs and the big decisions: MicroRNA regulation of photoperiodic flowering in Brachypodium distachyon.

Should I make flowers now, or wait and maybe develop a few more leaves? It’s a decision with important implications for reproductive success of wild plants and yields of domesticated plants. Plants can't call a friend to ask for advice on this big decision; instead, they rely on their ability to interpret signals from multiple sources (reviewed in Amasino, 2010). These inputs include endogenous...

T-DNA mutagenesis in Brachypodium distachyon.

During the past decade, Brachypodium distachyon has emerged as an attractive experimental system and genomics model for grass research. Numerous molecular tools and genomics resources have already been developed. Functional genomics resources, including mutant collections, expression/tiling microarray, mapping populations, and genome re-sequencing for natural accessions, are rapidly being devel...

Dissecting cis-regulation of FLOWERING LOCUS T.

Flowering in many plants is strongly influenced by daylength. Arabidopsis thaliana FLOWERING LOCUS T (FT) encodes a small peptide that is now widely recognized as a major component of florigen, a systemic signal that induces flowering in response to daylength (Turck et al., 2008). FT is expressed in phloem companion cells, and the protein is translocated through the phloem to the shoot apical m...

Endosperm development in Brachypodium distachyon

Grain development and its evolution in grasses remains poorly understood, despite cereals being our most important source of food. The grain, for which many grass species have been domesticated, is a single-seeded fruit with prominent and persistent endosperm. Brachypodium distachyon, a small wild grass, is being posited as a new model system for the temperate small grain cereals, but little is...
