This duplicated rice segment was the largest of five segmental duplications between Os01 and Os05 covering 354 duplicated gene pairs indicated by grey connecting lines (os01_05_5, Figure 4a, Table S1 of Additional file 1).
In the first, shared synteny between Hv5H and Os03 was supported by 65 barley ESTs (hv5H_os03_1, Table S3 of Additional file 1) but only by 7 ESTs from Hv2H (hv2H_os07_2, Table S3 of Additional file 1) to the corresponding duplicated segment on rice Os07 (segment pair os03_07_2, R_1 in Figure S4 of Additional file 1).
Analysis of the TIGR rice segmental duplication database revealed 30 MADS-box genes within the duplicated segments of rice chromosomes.
Analysis of the TIGR rice segmental duplication database revealed 19 MADS-box genes that were localized on the duplicated segments of the rice genome.
The molecular analyses revealed for two of the examined rice market segments that male and female pools were genetically divergent (Fig. 2).
Among the major rice market segments, the most pronounced gains have concerned prices of lower and higher quality Indica rice.
The Rice Crackers segment manufactures sugar coated crackers, savoury crackers and fried crackers.
The same group recently used rpl5 to probe the rearranged region in the mitochondrial genome and identified the WA-CMS gene, named WA352 (Wild Abortive 352), which is comprised of three rice mitochondrial genomic segments (orf284, orf224, and orf288) and one segment of unknown origin (Figure 1), and encodes a 352-residue putative protein with three transmembrane segments (Luo et al. [2013]).
For dissection of epidermal and ground tissues of rice, the root segments were fixed in FAA (formaldehyde, 95% ethanol and acetic acid in the volume of 10 85:4) solution for at least 24 hours in 4°C.
While small paracentric inversions and reduction of chromosome numbers were species specific, genome reorganization after WGD preceded taxon divergence as shared synteny extended the boundaries of rice duplicated genomic segments originating from WGD and only low levels of differential gene loss were found.
