Project description:Peanut (Arachis hypogaea) has a large (~2.7 Gbp) allotetraploid genome with closely related component genomes making its genome very challenging to assemble. Here we report genome sequences of its diploid ancestors (A. duranensis and A. ipaënsis). We show they are similar to the peanutâs A- and B-genomes and use them use them to identify candidate disease resistance genes, create improved tetraploid transcript assemblies, and show genetic exchange between peanutâs component genomes. Based on remarkably high DNA identity and biogeography, we conclude that A. ipaënsis may be a descendant of the very same population that contributed the B-genome to cultivated peanut.

Project description:Rhizoctonia solani Kühn is a soilborne basidiomycetous fungus that causes significant damage to many economically important crops. R. solani isolates are classified into 13 Anastomosis Groups (AGs) with interspecific subgroups having distinctive morphology, pathogenicity and wide host range. However, the genetic factors that drive the unique fungal pathology are still not well characterized due to the limited number of available annotated genomes. Therefore, we performed genome sequencing, assembly, annotation and functional analysis of 13 R. solani isolates covering 7 AGs and selected subgroups (AG1-IA, AG1-IB, AG1-IC, AG2-2IIIB, AG3-PT, AG3-TB, AG4-HG-I, AG5, AG6, and AG8). Here, we report a pangenome comparative analysis of 13 R. solani isolates covering important groups to elucidate unique and common attributes associated with each isolate, including molecular factors potentially involved in determining AG-specific host preference. Finally, we present the largest repertoire of annotated R. solani genomes, compiled as a comprehensive and user-friendly database, viz. RsolaniDB. Since 7 genomes are reported for the first time, the database stands as a valuable platform for formulating new hypotheses by hosting annotated genomes, with tools for functional enrichment, orthologs and sequence analysis, currently not available with other accessible state-of-the-art platforms hosting Rhizoctonia genome sequences.

Project description:Replication of the eukaryotic genome occurs in the context of chromatin, a nucleoprotein packaging state consisting of repeating nucleosomes. Chromatin is commonly thought to carry epigenetic information from one generation to the next, although it is unclear how such information survives the disruptions of nucleosomal architecture that occur during genomic replication. Here, we sought to directly measure a key aspect of chromatin structure dynamics during replication â how rapidly nucleosome positions are established on the newly-replicated daughter genomes. By isolating newly-synthesized DNA marked with the nucleotide analogue EdU, we characterize nucleosome positions on both daughter genomes of budding yeast during a time course of chromatin maturation. We find that nucleosomes rapidly adopt their mid log positions at highly-transcribed genes, and that this process was impaired upon treatment with the transcription inhibitor thiolutin, consistent with a role for transcription in positioning nucleosomes in vivo. Additionally, experiments in the Hir1Î background reveal a role for HIR in nucleosome spacing. Using strand-specific EdU libraries, we characterize nucleosome positions on the leading and lagging strand daughter genomes, uncovering differences in chromatin maturation dynamics between the two daughter genomes at hundreds of genes. Our data define the maturation dynamics of newly-replicated chromatin, and support a role for transcription in sculpting the chromatin template. We have mapped changes in nucleosome positions on newly replicated DNA in a timecourse after genome replication. We have used Micrococcal Nuclease footprinting of cross linked chromatin to determine nucleosome positions and EdU (ethylene deoxy uridine) to mark nascent DNA strands. EdU incorporated into nascent DNA strands was biotinylated with Click chemistry and nascent DNA strand fragments were subsequently isolated using Streptavidin coated magnetic beads.
