TAIR Gene Symbols

Question

[pthom010]

Does anybody know where I can acquire a table of TAIR Gene Symbols? What I have is a file with TAIR locus IDs and I would like to get the gene symbols that correspond with them. I have some coding experience in Linux and R so if there is a solution based in either one of those resources, that would be even better.

Hey,

There are two approaches here.

1, org.At.tair.db

You can use the annotation DB packages from Bioconductor, specifically org.At.tair.db.

Copying my own answer from here: A: Biomart query returns NA when searching for entrez_id, while manual search works

library(org.At.tair.db)

genes <- c("AT2G14610","AT4G23700","AT3G26830",
  "AT3G15950","AT3G54830","AT5G24105")

keytypes(org.At.tair.db)

mapIds(org.At.tair.db, keys = genes,
  column = c('SYMBOL'), keytype = 'TAIR')
 AT2G14610  AT4G23700  AT3G26830  AT3G15950  AT3G54830  AT5G24105 
 "AtCAPE9"  "ATCHX17" "CYP71B15"     "NAI2"         NA    "AGP41"

select(org.At.tair.db, keys = genes,
  column = c('ENTREZID', 'SYMBOL', 'REFSEQ'), keytype = 'TAIR')

2, biomaRt

require(biomaRt)
tair_mart <- useMart(biomart = 'plants_mart',
  host = 'plants.ensembl.org', dataset = 'athaliana_eg_gene')

head(listAttributes(tair_mart), 15)

annot <- getBM(
  values = genes,
  mart = tair_mart,

If you want a complete table from biomaRt, just use:

annotComplete <- getBM(
  mart = tair_mart,
  attributes = c('ensembl_gene_id', 'entrezgene_id',
    'description', 'external_gene_name'))

dim(annotComplete)
