List of assigned Hop names

Procedure for Hop name assignment:

  1. Verify that the protein/gene in question meets one of the criteria for Hop name assignment (see criteria for Hop name assignment), but is NOT part of a previously characterized family and subgroup (see protocol for phylogenetic analysis)
  2. If part of a novel family, name the new Hop using the next available alphabetic character(s). Assign a subgroup number of "1" and a subscript denoting source pathovar and strain (see list of pathovar abbreviations)
  3. If part of a novel subgroup in a previously characterized family, assign the next available subgroup number within that family, together with a subscript denoting source pathovar and strain
  4. Deposit the sequence in Genbank (see Genbank sequence deposition page). Names will not be added to the list of those assigned until release of the sequence by Genbank.
  5. Email the PPI site administrator to add the newly assigned name to the list below

Notes:

  • To facilitate phylogenetic analysis, a list of the sequences of all Hops in a given family can be found by clicking on the family name
  • More information on individual effectors, including references can be found in the Hop database (last updated 9-10-09)
  • Hop proteins originally named as Avrs and grandfathered into the new nomenclature are listed at the end of this page. Go to Avr list
