The primary contig assembly is 2.89 Gb long and consists of 865 contigs that were assembled with PacBio data generated with the company&rsquo;s Sequel<span>&reg;</span>&nbsp;System.

<p>RaGOO is a tool for coalescing genome assembly contigs into pseudochromosomes via minimap2 alignments to a closely related reference genome. The focus of this tool is on practicality and therefore has the following features:</p>
<ol>
<li>Good performance. On a MacBook Pro using Arabidopsis data, pseudochromosome construction takes less than a minute and the whole pipeline with SV calling takes ~2 minutes.</li>
<li>Intact ordering and orienting of contigs.</li>

  <title><![CDATA[Postdoc in Genomics of Pipefishes and Seahorses at NSF-funded postdoctoral project in Adam Jones' Lab]]></title>
  <description><![CDATA[
<p>An NSF-funded postdoctoral position is available in Adam Jones' Lab<br />at the University of Idaho to study the evolution and development of<br />the male's brood pouch in syngnathid fishes (seahorses, pipefishes<br />and seadragons). The project is being conducted in collaboration<br />with Dr. William Cresko's group at the University of Oregon. The<br />postdoc will be involved in studies of comparative genomics across<br />the family Syngnathidae, investigations of brood pouch morphology, and<br />characterization of the brood pouch microbiome. The position will be<br />funded for two years, with the possibility of a third year. The postdoc<br />will be based at the University of Idaho and will interact extensively<br />with the Cresko Lab at the University of Oregon.</p>

<p>The University of Idaho is in Moscow, a small college town located in<br />Northern Idaho on the Washington border. Moscow is widely considered to<br />be a great place to live, and it's known for a pleasant downtown, active<br />farmer's market, and nearby recreational opportunities. All of Moscow<br />is within biking or walking distance of the University of Idaho. For<br />more information about Moscow, see https://visitmoscowid.com/.</p>

<p>The University of Idaho has very strong faculty in evolution and<br />genomics in multiple departments and interdisciplinary programs. Of<br />particular note are the Bioinformatics and Computational Biology<br />Program (BCB: https://www.uidaho.edu/sci/bcb/people/faculty) and<br />the Institute for Bioinformatics and Evolutionary Studies (IBEST:<br />https://www.ibest.uidaho.edu/index.php). In addition, the University of<br />Idaho is only eight miles from Washington State University in Pullman, and<br />faculty from the two institutions interact and collaborate extensively.</p>

<p>Minimum qualifications include: a Ph.D. in biological sciences,<br />bioinformatics, or a related discipline; experience conducting research<br />in genomics or evolutionary biology, as evidenced by publications<br />in peer-reviewed journals; and evidence of strong written and oral<br />communication skills.  Experience analyzing next-generation sequence<br />data and familiarity with the genomics of marine fishes are desirable<br />but not required.</p>

<p>Apply at: https://uidaho.peopleadmin.com/postings/30003</p>

<p>Review of applications will begin January 15, 2021. The start date<br />is flexible.</p>

<p>The University of Idaho is an equal opportunity/Affirmative Action/equal<br />access employer.</p>

<p>Informal inquiries are encouraged and can be directed to Adam Jones<br />(adamjones@uidaho.edu).</p>

	<title><![CDATA[Unlocking Evolutionary Secrets: A Dive into Comparative Genomics Methods]]></title>
	<description><![CDATA[<p>Comparative genomics is the art and science of comparing genomes&mdash;across species, within species, or even among individuals&mdash;to unravel evolutionary relationships, functional elements, and genetic adaptations. As sequencing technologies have advanced and genome databases have expanded, comparative genomics has become a cornerstone of modern biology, shedding light on everything from antibiotic resistance in bacteria to human disease genetics.</p><p>In this post, we&rsquo;ll explore the core methods used in comparative genomics, the questions they help answer, and how they&rsquo;re shaping our understanding of life.</p><p><strong>1. Whole-Genome Alignment</strong><br />Whole-genome alignment involves mapping the entire genome of one species to another. Tools like MUMmer, MAUVE, and LASTZ perform large-scale sequence alignments to detect conserved regions, rearrangements, insertions, and deletions.</p><p>Use Case:<br />Comparing human and chimpanzee genomes to identify evolutionary conserved sequences (ECS) and regions of divergence.</p><p>Key Challenges:<br />Handling repetitive sequences and genome rearrangements.</p><p>Computational complexity in large genomes.</p><p><strong>2. Synteny and Collinearity Analysis</strong><br />Synteny refers to conserved blocks of gene order across species. Tools like MCScanX, SynMap, or CHITRA (for visualizing synteny interactively) detect these blocks to understand chromosomal evolution.</p><p>Use Case:<br />Studying ancient genome duplications in plants.</p><p>Investigating chromosomal rearrangements in cancer genomes.</p><p><strong>3. Ortholog and Paralog Detection</strong><br />Orthologs are genes in different species that evolved from a common ancestor, while paralogs are genes duplicated within a genome. Identifying them is crucial for functional annotation and evolutionary studies.</p><p>Popular Tools:<br />OrthoFinder, Orthologous MAtrix (OMA), InParanoid, and EggNOG.</p><p>Use Case:<br />Functional prediction of uncharacterized genes based on orthologs in model organisms.</p><p>Tracing gene family evolution.</p><p><strong>4. Phylogenomic Analysis</strong><br />Phylogenomic methods combine phylogenetics and genomics to infer evolutionary trees based on genome-wide data. These methods can handle dozens to hundreds of genomes, using concatenated alignments or gene trees.</p><p>Tools:<br />RAxML, IQ-TREE, ASTRAL, Phylip, BEAST.</p><p>Use Case:<br />Resolving the evolutionary relationships between microbial species.</p><p>Studying speciation events.</p><p><strong>5. Pan-Genome Analysis</strong><br />The pan-genome consists of the core genome (shared by all strains) and the accessory genome (strain-specific genes). This is especially popular in microbial genomics.</p><p>Tools:<br />Roary, Panaroo, BPGA, PGAP.</p><p>Use Case:<br />Understanding virulence factor diversity in E. coli.</p><p>Designing broad-spectrum vaccines.</p><p><strong>6. Comparative Transcriptomics</strong><br />Comparing transcriptomes across species or conditions reveals conserved and unique expression patterns. RNA-seq data can be mapped to reference genomes to identify orthologous expression profiles.</p><p>Use Case:<br />Comparing stress response in extremophiles and model species.</p><p>Studying conserved regulatory networks.</p><p><strong>7. Functional Element Comparison</strong><br />Beyond genes, comparative genomics also targets non-coding regions&mdash;enhancers, promoters, miRNAs. Conservation across species often implies functional importance.</p><p>Tools:<br />PhastCons, GERP, phyloP (based on multiple alignments).</p><p>Use Case:<br />Detecting conserved non-coding elements in vertebrates.</p><p>Studying regulatory divergence in human evolution.</p><p><strong>8. Horizontal Gene Transfer (HGT) Detection</strong><br />In microbes, genes often jump across species boundaries. Comparative genomics can detect HGT by identifying genes that defy the expected phylogenetic pattern.</p><p>Tools:<br />HGTector, DarkHorse, AlienHunter, SIGI-HMM.</p><p>Use Case:<br />Tracing antibiotic resistance genes.</p><p>Exploring microbial adaptability in extreme environments.</p><p><strong>Final Thoughts</strong><br />Comparative genomics is a powerful lens to observe the diversity and unity of life. With a broad toolkit&mdash;from aligners to orthology pipelines, phylogenetic engines to visualization tools&mdash;it allows scientists to ask big questions: How did genomes evolve? What makes species unique? Where do new genes come from?</p><p>Whether you're studying extremophiles, building better crops, or exploring human ancestry, comparative genomics offers the methods to connect the dots across the tree of life.</p><p>&nbsp;</p>]]></description>
