Ultraconserved elements (UCEs), stretches of DNA that are identical between distantly related species, are enigmatic genomic features whose function is not well understood. First identified and characterized in mammals, UCEs have been proposed to play important roles in gene regulation, RNA processing, and maintaining genome integrity. However, because all of these functions can tolerate some sequence variation, their ultraconserved and ultraselected nature is not explained. We investigated whether there are highly conserved DNA elements without genic function in distantly related plant genomes. We compared the genomes of Arabidopsis thaliana and Vitis vinifera; species that diverged ∼115 million years ago (Mya). We identified 36 highly conserved elements with at least 85% similarity that are longer than 55 bp. Interestingly, these elements exhibit properties similar to mammalian UCEs, such that we named them UCE-like elements (ULEs). ULEs are located in intergenic or intronic regions and are ...
There are 481 segments longer than 200 base pairs (bp) that are absolutely conserved (100% identity with no insertions or deletions) between orthologous regions of the human, rat, and mouse genomes. Nearly all of these segments are also conserved in the chicken and dog genomes, with an average of 95 and 99% identity, respectively. Many are also significantly conserved in fish. These ultraconserved elements of the human genome are most often located either overlapping exons in genes involved in RNA processing or in introns or nearby genes involved in the regulation of transcription and development. Along with more than 5000 sequences of over 100 bp that are absolutely conserved among the three sequenced mammals, these represent a class of genetic elements whose functions and evolutionary origins are yet to be determined, but which are more highly conserved between these species than are proteins and appear to be essential for the ontogeny of mammals and other vertebrates.

I am interested in determining if the secondary structure of several large (500bp+) sequences is conserved, with an ultimate goal of demonstrating greater divergence between the NTRs (the sequences here) versus ORFs between species. That is the coding regions have greater conservation than the non-coding. To do this I have been considering using the ViennaRNA services structure conservation analysis (SCA). However, after running the program I am finding the interpretation of the results not obvious to me.. The results can be found here: http://rna.tbi.univie.ac.at/cgi-bin/SCA.cgi?PAGE=3&ID=zwPrc7kAK8&r=36. For example the measure Basepair distance, pairwise provides a z-score of -7.045 with a p-value of zero. Obviously I can reject the null that my sequences are not different than the random sampling performed, but the sign of the value and how it related to conservation is where I am unsure. I pulled some of the papers they cite for the man pages of these programs and my thoughts are coming ...
Conservation has a cascading effect with numerous benefits, says a local biologist. Two entities in Stark County are furthering their missions of conservation in their own ways, but each wants to increase ties with the community and get people involved in conservation.
Care must be taken when choosing a suitable transformation, especially if conservation dollars are allocated to species in a ranked fashion. We advocate routine sensitivity analyses.

Residue conservation is an important, established method for inferring protein function, modularity and specificity. It is important to recognize that it is the 3D spatial orientation of residues that drives sequence conservation. Considering this, we have built a new computational tool, VENN that allows researchers to interactively and graphically titrate sequence homology onto surface representations of protein structures. Our proposed titration strategies reveal critical details that are not readily identified using other existing tools. Analyses of a bZIP transcription factor and receptor recognition of Fibroblast Growth Factor using VENN revealed key specificity determinants. Weblink: http://sbtools.uchc.edu/venn/.

This was revealed by the identification of individuals with a genetic condition lacking coding-region mutations in the gene commonly associated with the disease but having a variety of nearby chromosomal abnormalities, collectively described as cis-ruption disease cases. The congenital eye malformation aniridia is caused by haploinsufficiency of the developmental regulator PAX6. We discovered a de novo point mutation in an ultraconserved ...
G-protein coupled receptors (GPCRs) belong to biologically important and functionally diverse and largest super family of membrane proteins. Co-clustered GPCRs from human and other genomes, organized as 32 clusters, were employed to study the amino acid conservation patterns and species-specific or cluster-specific motifs. Critical analysis on sequence composition and properties provide clues to connect functional relevance within and across genome for vast practical applications such as design of mutations and understanding of disease-causing genetic abnormalities. and GPCRs, leading to 32 clusters of eight major types as explained in our previous publication [9], we report the analysis of AAS and conserved motifs in all 32 492445-28-0 IC50 clusters of GPCRs. This 492445-28-0 IC50 study was further extended to a cross-genome analysis of and GPCRs. Methodology Physique 1 summarizes stepwise procedure for the identification of conserved AA (motifs) and residues exchanged at each position on MSA. ...
A gene is a locatable region of genomic sequence, corresponding to a unit of inheritance, which is associated with regulatory regions, transcribed regions and/or other functional sequence regions.[1][2] The physical development and phenotype of organisms can be thought of as a product of genes interacting with each other and with the environment.[3] A concise definition of a gene, taking into account complex patterns of regulation and transcription, genic conservation and non-coding RNA genes, has been proposed by Gerstein et al.[4] A gene is a union of genomic sequences encoding a coherent set of potentially overlapping functional products. Colloquially, the term gene is often used to refer to an inheritable trait which is usually accompanied by a phenotype as in (tall genes or bad genes) -- the proper scientific term for this is allele. In cells, genes consist of a long strand of DNA that contains a promoter, which controls the activity of a gene, and coding and non-coding sequence. ...

Evolutionary relationships among birds in Neoaves, the clade comprising the vast majority of avian diversity, have vexed systematists due to the ancient, rapid radiation of numerous lineages. We applied a new phylogenomic approach to resolve relationships in Neoaves using target enrichment (sequence capture) and high-throughput sequencing of ultraconserved elements (UCEs) in avian genomes. We collected sequence data from UCE loci for 32 members of Neoaves and one outgroup (chicken) and analyzed data sets that differed in their amount of missing data. An alignment of 1,541 loci that allowed missing data was 87% complete and resulted in a highly resolved phylogeny with broad agreement between the Bayesian and maximum-likelihood (ML) trees. Although results from the 100% complete matrix of 416 UCE loci were similar, the Bayesian and ML trees differed to a greater extent in this analysis, suggesting that increasing from 416 to 1,541 loci led to increased stability and resolution of the tree.

Cephalochordates, the sister group of vertebrates + tunicates, are evolving particularly slowly. Therefore, genome comparisons between two congeners of Branchiostoma revealed so many conserved noncoding elements (CNEs), that it was not clear how many are functional regulatory elements. To more effectively identify CNEs with potential regulatory functions, we compared noncoding sequences of genomes of the most phylogenetically distant cephalochordate genera, Asymmetron and Branchiostoma, which diverged approximately 120-160 million years ago. We found 113,070 noncoding elements conserved between the two species, amounting to 3.3% of the genome. The genomic distribution, target gene ontology, and enriched motifs of these CNEs all suggest that many of them are probably cis-regulatory elements. More than 90% of previously verified amphioxus regulatory elements were re-captured in this study. A search of the cephalochordate CNEs around 50 developmental genes inseveral vertebrate genomes revealed ...
Next-generation DNA sequencing (NGS) offers a promising way to obtain massive numbers of orthologous loci to understand phylogenetic relationships among organisms. Of particular interest are old museum specimens and other samples with degraded DNA, where traditional sequencing methods have proven to be challenging. Low coverage shotgun sequencing and sequence capture are two widely used NGS approaches for degraded DNA. Sequence capture can yield sequence data for large numbers of orthologous loci, but it can only be used to sequence genomic regions near conserved sequences that can be used as probes. Low coverage shotgun sequencing has the potential to yield different data types throughout the genome. However, many studies using this method have often generated mitochondrial sequences, and few nuclear sequences, suggesting orthologous nuclear sequences are likely harder to recover. To determine the phylogenetic position of the galliform genus Tropicoperdix, whose phylogenetic position is currently
Transcription factors (TFs) regulate gene transcription and play pivotal roles in various biological processes such as development, cell cycle progression, cell differentiation and tumor suppression. Identifying cis-regulatory elements associated with TF-encoding genes is a crucial step in understanding gene regulatory networks. To this end, we have used a comparative genomics approach to identify putative cis-regulatory elements associated with TF-encoding genes in vertebrates. We have created a database named TFCONES (T ranscription F actor Genes & Associated CO nserved N oncoding E lementS) ( http://tfcones.fugu-sg.org ) which contains all human, mouse and fugu TF-encoding genes and conserved noncoding elements (CNEs) associated with them. The CNEs were identified by gene-by-gene alignments of orthologous TF-encoding gene loci using MLAGAN. We also predicted putative transcription factor binding sites within the CNEs.

N2 - After the most recent tetraploidy in the Arabidopsis lineage, most gene pairs lost one, but not both, of their duplicates. We manually inspected the 3,179 retained gene pairs and their surrounding gene space still present in the genome using a custom-made viewer application. The display of these pairs allowed us to define intragenic conserved noncoding sequences (CNSs), identify exon annotation errors, and discover potentially new genes. Using a strict algorithm to sort high-scoring pair sequences from the bl2seq data, we created a database of 14,944 intragenomic Arabidopsis CNSs. The mean CNS length is 31 bp, ranging from 15 to 285 bp. There are ≈1.7 CNSs associated with a typical gene, and Arabidopsis CNSs are ...
