Introduction
 Plant Research International
 Wageningen University & Research Centre
 Netherlands
 Identification & detection: molecular methods
 Quarantine plantpathogenic species
Introduction
Increase damaging plant pests and diseases:
• Expanding globalisation of trade in plant material,
• Climate change,
• EU expansion creating new borders and pathway
• Increasing regulation harmful organisms,
• Decline in the resources supporting plant health
activities on national and european level.
The Netherlands entry point for Europe:



Rotterdam: main harbour
Amsterdam Schiphol: main airport
Aalsmeer: main auction
In- and Export of goods:

Agricultural products

Expansion of the EU
• European Union
• 1952: 6 countries
• 1973: 9 countries
• 1995: 15 countries
• 2004: 25 countries
• 2011: 27 countries
Climate change: Global warming

Emerging Pathogens

Introduction of new pests
Survival
Spread
Suppress native population
Decline in taxonomic / fytosanitary
experience
• Retirement of specialists
• No new students in taxonomy and
phytopathology
• Not sexy
• Decline in resources for projects
Agricultural products in danger
Phytophthora ramorum
Targets Quarantine
 Which?

Fungi
 Arthropods

Bacteria

Nematodes

Viruses

Phytoplasmas
Anoplophora chinensis
Xanthomonas fragariae
Pinewood nematode
 Council Directive 2000/29/EC
 EPPO list A1 and A2
Phytoplasm
Polerovirus
Importance Fytosanitary Regulations:
• Food security / Sustainable food production
• Biodiversity
• Economic trade
Phytosanitary Regulations:
• ICPP : International Plant Protection Convention
(1997)
•
Countries allowed to apply import permission
•
Countries obliged to establish NPPO’s
•
Phytosanitary standards (ISPMs)
• Europe
•
EU Directive 2000/29
•
Approx. 300 harmful organisms: A1/A2
•
PFC: Permanent Phytosanitary Commitee
•
EPPO: > 50 countries
Fytosanitary Collections, important for:
• Studying Biodiversity
• Studying Evolution
• Studying Taxonomy
Collections are also extremely important as source for
taxonomic studies and development of detection- and
identification methods for harmful organisms.
• Reference material within these collections
For controls and for the calibration of for example
equipment and media.
Collections can contain:
• living material: bacteria, fungi
• dead material: insects, nematodes
• tissue cultures
• whole plants (viruses, phytoplasmas)
• genetic material (DNA/RNA)
Fytosanitary collections
• Bacteria, Fungi, Nematodes, Insects, Viruses /
Viroids, Phytoplasmas
• Correctly identified by taxonomic experts
• Material available for reference (NRC, NPPO)
• DNA/RNA available
• ISO certification
• Funding
• Collaboration
Future Collections
• Optimal long-term use of collection material
• Good management and maintenance is
essential
• Material should be correctly identified
• Latest insights on the name placed material
should be preserved
• Equipment should also be easily accessible,
retrievable and interchangeable
Collections
• ECCO: europe
• WFCC: world
• Mainly focussing on bacteria, fungi
• No nematodes, insects, phytoplasmas,
viruses
• Project Q-collect: phytosanitary collections
Databases
• Current databases of molecular data are
incomplete and have erroneous data;
coordinated action
across the research
infrastructure using
authenticated strains will
ensure our future ability
to identify and utilise
new species.
DNA barcode identification

Q-bank (www.q-bank.eu)
• A dynamic open-access database of regulated plant
pests and look-alikes,
• Linked to curated and publicly accessible reference
collections,
• The database contains sequence data,
morphological data including photographs,
nomenclatural and
diagnostic data,
• The reference collections comprise voucher
specimens,
tissue and whole genome amplified
DNA/RNA samples.
