Associations between sorghum and rice rhizomatous and ratooning QTLs and candidate differentially expressed ESTs. Rice chromosome 1 and the corresponding sorghum QTL are shown in the printed volume; figures for the remaining chromosomes are available in Supplemental Figure S1. Comparative maps with QTLs by Hu et al. (2003) are modified according to physical data from TIGR release 2 rice pseudomolecules. In Figure 1 and/or its supplements, lines drawn to rice chromosome crossbars show BLASTn-supported locations of sorghum-rice anchor markers (as described in text). Additional anchor markers with inferred genetic positions based on either the Paterson et al. (1995) or high-density sorghum map (Bowers et al., 2003) are indicated by §. Loci added by BLASTn to the TIGR release 3 physical assembly are indicated by *. Anchor markers connected by dashed lines reflect changed positions, relative to the report by Hu et al. (2003), as determined based on the current rice pseudomolecules. ♦ indicates best BLASTn hits are to other genomic positions. Other observed discrepancies in colinearity of the Rice-IRRI RD23/Olong F2 QTL 2003 population mapped markers and the TIGR version 2 physical assembly are indicated by RM and OSR markers located to the right of the rice chromosome. For example, the physical map order of three markers, OSR13-OSR16-RM36, flanking the Rhz2 locus deviates from the genetic order of OSR16-RM36-OSR16.
