How many genes in Tomato ?

Tomato Genome Update-1:

  • The genome size of tomato is ca. 900 MB (Approximate values: Human genome is 3000 MB, rice genome is 370 MB, Arabidopsis genome  is 130 MB, E.coli genome is 4.5 MB)
  • Total number of protein coding genes: 34,727 (8615 groups common between rice, Arabidopsis, grape, tomato and potato; 1727 groups are common between tomato, potato and grape, 727 groups are common between tomato, potato and grape).
  • There are 96 conserved miRNA genes
  • A whole genome triplication occurred in the Solanum lineage followed by widespread gene loss (71 million years ago). Tomato genome can be partitioned into three non-overlapping subgenomes.
