Figure 1.
Frequency of different motifs among the eSSRs of P. euphratica.
Figure 2.
Distribution of eSSRs across the 5′ UTR, 3′ UTR and CDS in P. euphratica.
(A). Abundance of eSSRs with different motif sizes and their distributions in non-coding and coding region (B).
Figure 3.
Transferability of polymorphic eSSRs.
The uppermost figure shows the transferability of the 305 polymorphic eSSRs over nine species of Populus and P. euphratica. The lower figure shows a Neighbor-Joining tree for the tested species based on eSSR transferability. The box in the upper right-hand side of the figure shows the symbols used to indicate species belonging to different sections of the genus Populus.
Figure 4.
In silico mapping of the P. euphratica eSSRs onto P. trichocarpa pseudo-chromosomes.
Gray columns represent 19 pseudo-chromosomes of P. trichocarpa. P. euphratica eSSRs are arranged on these pseudo-chromosomes, with green lines representing experimentally validated EST-SSRs and red lines indicating EST-SSRs that are not validated.
Figure 5.
Bar diagram of GO enrichment of SSR-containing ESTs compared to total ESTs.
The Y axis represents significantly enriched GO terms and the X axis represents the relative frequency of the GO term.
