Fig. 1From: Dynamics of gene expression during development and expansion of vegetative stem internodes of bioenergy sorghumMicroscopic cross sections of internodes of bioenergy sorghum inbred R.07020 at 60 DAP (days after planting). Internode1 (Int1) is the youngest sub-apical internode and internode 4 (Int4) is the oldest fully expanded internode. Stem sections were stained with safranin and alcian blue. Samples were from the middle section of each internodeBack to article page
