From this page you can browse and download the whole genome sequence of the Velaso et al., 2010 published apple genome assembly v1.0; predicted gene transcripts, their locations and putative function based on homology to known genes. You can BLAST your sequences against the genome sequence, the predicted genes and associated transcripts. You can search and browse the chromosomes, predicted genes and markers in GBrowse and view the evidence for each prediction and feature.    There are two asemblies currently available

The original contig-based assembly from the Velaso et al., 2010 publication

  1. Pseudo haplotype assemblies derived from the original contigs
  2. Use the resources side-bar to view details and download files for these assemblies.

The Malus x domestica v1.0 genome assembly files are available in FASTA and GFF3 formats.  There are no pseudomolecule (chromosome) sequence files available for this assembly because of the multiple haplotypes present in the assembly.   Please see the Malus x domestica v1.0 pseudo haplotype (primary assembly) for a pseudomolecule sequence.

Gene Predictions

Gene models were predicted on the assembly contigs using various gene prediction tools such as Glimmer, FGENESH, Genewise, GMAP and Twinscan.  A final consensus gene set was constructed using evidence derived from all of these gene prediction tools.  Both the consensus sequences and alternate gene models are available for download below.  The consensus genes have been mapped to chromosomal positions.  However this is for convinence as there is no chromosomal sequence for this assembly.  

5' and 3' UTR regions are currently not available for gene models

RosBREED Resequencing Alignments

A total of 31 different apple accessions were resequenced using Illumina short-read technology.  The reads were trimmed and aligned to the Malus x domestica v1.0 contig assembly and are available in BAM alignment files.

It is not necessary to download the BAM alignment files. Some are very large and multiple downloads may oversubscribe the network bandwidth. Rather, use the following instructions for viewing the alignments.

To view the strawberry resequencing alignments please follow these instructions:

  1. Download the file. This file contains the reference sequence and gene models. After downloading, unzip this file in your working directory.
  2. Launch the Integrative Genomics Viewer (IGV). Launch the version appropriate for the amount of memory you have available on your computer
  3. After IGV starts, load the genome file downloaded in the first step by clicking the menu item GenomesLoad Genome From File. Navigate to the folder where you unpacked the zip file from step 1 and select the file named Malus_x_domestica_v1.0.contigs.genome.
  4. Select an alignment file you wish to view by right-clicking on a file with a .bam extension and select the option Copy link location (in Chrome and Firefox), Copy shortcut (in Internet Explorer) or Copy link (in Safari).
  5. Add the alignment as a track in IGV by clicking the menu item FileLoad from URL. Paste the URL copied in the previous step into the box.
  6. You may load as many alignment files as you want

All assembly and annotation files are available for download by selecting the desired data type in the right-hand "Resources" side bar.  Each data type page will provide a description of the available files and links do download.
