The origins of genomic duplications in Arabidopsis.
Large segmental duplications cover much of the Arabidopsis thaliana genome. Little is known about their origins. We show that they are primarily due to at least four different large-scale duplication events that occurred 100 to 200 million years ago, a formative period in the diversification of the angiosperms. A better understanding of the complex structural history of angiosperm genomes is ne...
متن کاملDetection of Genomic Duplications and Deletions
Gene and chromosome duplications have been implicated as fundamental evolutionary mechanisms (Ohno et al.,1968; Li and Gojobori, 1983; Schughart et al., 1989). For the purpose of this chapter, duplications and deletions are defined as those too large to be routinely detected by sequencing or simple PCR-based methods (100 bp), but too small to be detected by conventional cytogenetic metaphase a...
متن کاملHighly Efficient Compensation-based Parallelism for Wavefront Loops on GPUs
Wavefront loops are widely used in many scientific applications, e.g., partial differential equation (PDE) solvers and sequence alignment tools. However, due to the data dependencies in wavefront loops, it is challenging to fully utilize the abundant compute units of GPUs and to reuse data through their memory hierarchy. Existing solutions can only optimize for these factors to a limited extent...
متن کاملTranslational compensation of genomic instability in neuroblastoma
Cancer-associated gene expression imbalances are conventionally studied at the genomic, epigenomic and transcriptomic levels. Given the relevance of translational control in determining cell phenotypes, we evaluated the translatome, i.e., the transcriptome engaged in translation, as a descriptor of the effects of genetic instability in cancer. We performed this evaluation in high-risk neuroblas...
متن کاملControlling Size When Aligning Multiple Genomic Sequences with Duplications
For a genomic region containing a tandem gene cluster, a proper set of alignments needs to align only orthologous segments, i.e., those separated by a speciation event. Otherwise, methods for finding regions under evolutionary selection will not perform properly. Conversely, the alignments should indicate every orthologous pair of genes or genomic segments. Attaining this goal in practice requi...
