Mosses compose one of the three lineages of bryophytes. Today, about 13,000 species of mosses are recognized from across the globe, and at least one-third of this diversity composes the Hypnales, a lineage characterized by an early rapid radiation. We sequenced and de novo assembled the genomes of two hypnalean mosses, namely Entodon seductrix and Hypnum curvifolium, based on the 10x genomics and Hi-C data. The genome assemblies of E. seductrix and H. curvifolium comprise 348.4 and 262.0 Mb, respectively, estimated by k-mer analyses to represent 93.3% and 97.2% of their total genome size. Both genomes were assembled at the chromosome level, with scaffold N50 of 30.0 and 20.7 Mb, respectively. The annotated genome of E. seductrix comprises 25,801 protein-coding genes and that of H. curvifolium 29,077, estimated to represent 96.8% and 97.2%, respectively, of the total gene spaces based on BUSCO (Benchmarking Universal Single-Copy Ortholog) assessment. For both genomes, most contigs were anchored to the largest 11 pseudomolecules, corresponding to the 11 chromosomes of the two species, and each with a putative sex-related chromosome characterized by low gene density. The chromosomes of E. seductrix and H. curvifolium are highly syntenic, suggests limited architectural shifts occurred following the rapid radiation of the Hypnales. We compared their genomic features to the model moss Physcomitrium patens. The hypnalean moss genomes lack signatures of recent whole-genome duplication. The presented high-quality moss genomes provide new resources for comparative genomics to potentially unveil the genomic evolution of derived moss lineages.

View all literature mentionsSoftware program for phylogenetic analyses of large datasets under maximum likelihood.
View all literature mentionsA comparative platform for green plant genomics. Families of orthologous and paralogous genes that represent the modern descendents of ancestral gene sets are constructed at key phylogenetic nodes. These families allow easy access to clade specific orthology / paralogy relationships as well as clade specific genes and gene expansions. As of release v9.1, Phytozome provides access to forty-one sequenced and annotated green plant genomes which have been clustered into gene families at 20 evolutionarily significant nodes. Where possible, each gene has been annotated with PFAM, KOG, KEGG, and PANTHER assignments, and publicly available annotations from RefSeq, UniProt, TAIR, JGI are hyper-linked and searchable.
View all literature mentionsSoftware package as multiple alignment program for amino acid or nucleotide sequences. Can align up to 500 sequences or maximum file size of 1 MB. First version of MAFFT used algorithm based on progressive alignment, in which sequences were clustered with help of Fast Fourier Transform. Subsequent versions have added other algorithms and modes of operation, including options for faster alignment of large numbers of sequences, higher accuracy alignments, alignment of non-coding RNA sequences, and addition of new sequences to existing alignments.

Pair aware preprocessing tool optimized for Illumina next generation sequencing data. Includes several processing steps for read trimming and filtering. Operating systems Unix/Linux, Mac OS, Windows.
View all literature mentionsIntegrated database resource consisting of 16 main databases, broadly categorized into systems information, genomic information, and chemical information. In particular, gene catalogs in completely sequenced genomes are linked to higher-level systemic functions of cell, organism, and ecosystem. Analysis tools are also available. KEGG may be used as reference knowledge base for biological interpretation of large-scale datasets generated by sequencing and other high-throughput experimental technologies.
View all literature mentionsSoftware tool that screens DNA sequences for interspersed repeats and low complexity DNA sequences. The output of the program is a detailed annotation of the repeats that are present in the query sequence as well as a modified version of the query sequence in which all the annotated repeats have been masked (default: replaced by Ns). Currently over 56% of human genomic sequence is identified and masked by the program. Sequence comparisons in RepeatMasker are performed by one of several popular search engines including nhmmer, cross_match, ABBlast/WUBlast, RMBlast and Decypher. RepeatMasker makes use of curated libraries of repeats and currently supports Dfam ( profile HMM library ) and RepBase ( consensus sequence library ).
