on the Taxonomy of Plant Pathogenic Bacteria
of the meeting of the ISPP Committee on Taxonomy of Plant Pathogenic
Bacteria held in Edinburgh, Scotland, UK on 13 July 2006.
Committee met at the 11th International Conference on Plant Pathogenic
Bacteria, Edinburgh, Scotland, UK, 10-14 July 2006.
Drs C. Bull (present by conference call), S. De Boer, M. Fischer-Le
Saux, G. Saddler, M. Scortichini, D. Stead, Y. Takikawa and J. Young, as
members of the Committee, and 22 members of the conference attended.
17:30h; Chair Dr J. Young
Received from Drs. G. Firrao, and T. Denny.
The Committee had not formally convened since the meeting in
Charlottetown, PEI, Canada in 2000, but an informal meeting was held at
the ISPP meeting in Christchurch, New Zealand in 2002.
Minutes of the last meeting at Charlottetown taken as read. The
following actions initiated at the previous meeting were discussed:
At the request of the Committee a website was created by the ISPP
Secretariat within the ISPP website in 2001. Various documents including
the minutes of the Committee meeting at the previous NCPPB Conference, the
International Standards for Naming Pathovars, the List of Names of Plant
Pathogenic Bacteria 1864-1996, and annual updates of names after 2000 have
been posted. An ongoing problem has been to update and correct the website
through the ISPP Secretariat. Recently, the website was placed under the
direct control of Committee.
The List of Names was up-dated in 2004 and was recently posted.
A discussion forum was initiated but it is largely inactive,
perhaps because of a lack of awareness of the site.
We wrote a Letter to Phytopathology
in explanation of misunderstandings about the Bacteriological Code and the
International Standards for Naming Pathovars.

A letter was sent to the USDA/ARS Dr. R. Gingery re: US Culture
Collection of Plant Pathogenic Bacteria supporting the establishment of
culture collections in the United States dedicated to plant pathogenic
bacteria. J.B. Jones is
heading an ad-hoc committee for the American Phytopathological Society to
look for a long-term solution to the lack of resources for permanent
microbial culture collections in the US.
work of the Committee over the last 6 years.
The Committee is reactive, keeping an up to-date list of names, and
standards, commenting when names are proposed that do not meet the
Standards. The Committee has
commented twice in situations when proposals were viewed as unhelpful to
the wider community of plant pathogens.
An intention to contact journal editors to ensure that they are
aware of the Committee as a possible source of manuscript reviewers for
nomenclatural proposals was not pursued because of uncertainties over the
question of which journals should be approached.
The Committee has worked on the question of ‘Terms of
Reference’ for the committee. Although not a requirement for ISPP
Subject Matter Committees, it has been felt that some guiding framework
should be developed. The
Committee is working on proposals for rotation of Committee membership
that encourage a high level expertise.
One suggestion was for those interested and with the expertise to
send their names and contact information for consideration and nomination
by the Committee. Guiseppe Firrao previously developed a survey of the
Committee to help determine what expertise is needed.
Those interested could be sent this form to fill out.
Our goal for the List of Names is to have the Website up-date the
list as citations proposing the names are sent. Authors are encouraged to
send publications of new pathogens to the Committee to ensure they are not
missed. Need means of contacting the Committee so we need to publicise our
contact details. Carolee
would like to have a webform that they could use to send the information.
When they were first chosen, pathotype strains were originally selected
from historical data. Since then some have been identified as not
representative of the pathogen. The
Committee proposed the following corrections to pathotype strains:
ATCC 7386; CFBP 2104*; ICMP 3988*; LMG 5070; NCPPB 537
ICMP 3507; NCPPB 1436
