Gene Details:

  • Gene ID:
  • Gene Symbol: Rpi-blb2
  • Gene Name: blight resistance protein Rpi-blb2
  • Genome:
  • Species: Solanum bulbocastanum

Functional Descriptions:

  • The Rpi-blb2 gene from Solanum bulbocastanum is an Mi-1 gene homolog conferring broad-spectrum late blight resistance in potato.
  • The Rpi-blb2 locus was initially mapped in several tetraploid backcross populations, derived from highly resistant complex interspecific hybrids designated ABPT (an acronym of the four Solanum species involved:S. acaule, S. bulbocastanum, S. phureja and S. tuberosum), to the same region on chromosome 6 as the Mi-1 gene from tomato, which confers resistance to nematodes, aphids and white flies.
  • The Rpi-blb2 protein shares 82% sequence identity to the Mi-1 protein.
  • Significant expansion of the Rpi-blb2 locus compared to the Mi-1 locus indicates that intrachromosomal recombination or unequal crossing over has played an important role in the evolution of the Rpi-blb2 locus.
