While numerous studies described the genomic structure of this allohexaploid using cytogenetic methods, the present study provides a new insight into the genome structure based on sequencing followed by genomic in situ hybridization (GISH).
Analysis of the mG5PR genomic structure is based on NCBI contig NW_001030500, which is located on chromosome 12C2 (56 Mb, ENSEMBLE ContigView) and contains the entire gene (Ppp2r3c, MGI: 193009).
a The OsVPE3 gene structure based on the genomic sequence and full-length cDNA clone (BAC41387).
In agreement with the predicted transcript structure based on the genomic DNA alterations that we observed, all RT-PCR products showed a deletion of exons 2 5, with a subset of products exhibiting an additional deletion extending through exon 6 (Figure 2B).
In general, as shown in the principal components analysis (PCA) clustering, the vertical phylogenetic relevance was well conserved in the cluster structure, based on the genomic clusters of orthologous groups (COG) content distance, and enriched the genome-scale perspective of lateral evolution at a functional level.
Users can therefore view and navigate genomic scaffolds, which include information for gene annotations, gene structure (based upon OGSv1), ESTs and PXS genes.
Again, we propose a different gene structure based on the analysis of the genomic DNA, where the translation extends into the first postulated intron and ends shortly afterwards.
In this direction, another major initiative is Genome3D, which is a collaborative project to annotate genomic sequences with predicted 3D structures based on CATH (Class, Architecture, Topology, Homology) and SCOP domains to infer protein function.
GeneSeqer [ 87] was used to generate putative transcript structures based on an alignment of ESTs to the corresponding genomic loci.
To overcome these problems, we implemented our own memory-efficient data structures based on native data types and optimized containers, such as sparse arrays covering genomic regions.
