Fig 1.
Growth form of Setaria italica (foxtail millet) and S. viridis (green foxtail).
Setaria viridis produces multiple tillers and aerial branches whereas S. italica only produces one or a few tillers and no aerial branches. A. S. italica, B. S. viridis, C. S. viridis showing tillers numbered from the first produced tiller (I-VI), D. S. viridis, with tillers separated so that secondary tillers can be better displayed. Scale A = 12 mm, B-D = 8 mm.

PCA analysis of the relationship between architectural traits at both flowering and at harvest in each trial.
Fig 2.
Relationships between biomass and plant architectural traits.
Each panel represents a range of biomass values, with that on the left representing the lowest biomass and that on the right the highest. Height versus tiller number at harvest for each RIL is plotted in the appropriate panel depending on the biomass of the RIL. The size of the symbol is proportional to the number of aerial branches for the RIL (see legend at side of each figure). The values for S. italica and S. viridis are denoted by labeled arrows. A. Greenhouse, B. Field.
Fig 3.
QTL map showing the QTL locations for multiple traits on the nine chromosomes of Setaria. Boxes represent genomic regions where more than one branching or height or biomass QTL co-locate. Magenta stars on the line representing the chromosome represent the maximum LOD positions of flowering time QTL identified for the same mapping population by Mauro-Herrera et al. (2013). GH refers to the greenhouse trial, Field to the field trial.
