Coffee
 Coffee is the most important agricultural commodity, worth an estimated retail value
of 70 billion USD, crucial for the economy of more than 70 countries and the main
income resource for hundreds of millions people worldwide (ICO*, 2016).
There are more than 100
coffee species but only two,
Coffea arabica (Arabica) and
Coffea canephora (Robusta),
are commercially used for the
production of coffee as a
beverage
Major coffee producing
countries:
Brazil
Vietnam
Colombia

Coffee Leaf Rust
Coffee leaf rust (CLR) caused by the fungus Hemileia vastatrix (Hv) is
the most important disease of Arabica coffee
1867
1861
Lake
Victoria
Hv attacks coffee leaves and
causes defoliation, weakening
the plants and even leading to
death. Yield losses can reach
up to 30 %

a
CLR was first recorded in 1861 near Lake Victoria (East
Africa), but it caused the first major outbreak in 1869
in Ceylon (now Sri Lanka). The disease gained a
worldwide distribution, becoming practically endemic
in all regions of the world where coffee is grown
Coffee Berry Disease
Coffee Berry Disease (CBD) caused by the fungus Colletotrichum
kahawae (Ck) is the the main limiting factor of Arabica coffee
production at high altitude, in Africa
CBD
Ck = Biological weapon
CK infects green coffee berries
causing their mummification and
premature dropping. Yield losses
can reach up to 50-80%
CBD, first reported in Kenya in 1922, is
still restricted to Africa but its dispersal
to Latin America and Asia represents a
serious concern
In Tanzania 50% of the production costs are spent to control CLR and CBD using fungicides
CIFC – Centro Inv. Ferrugens do Cafeeiro (Coffee Rusts Research Centre)
The importance of coffee leaf rust as a threat to world production led, in 1955, the Governments of the
USA and Portugal (Agreement FO-PO-5, Project D. O. A. 72-11-004), to provide for the foundation of CIFC
in Portugal, where a pioneer work on this disease had been initiated by Prof. Branquinho d’ Oliveira.

CIFC’s main objectives: To centralize and develop, at international co-operation level, the research on
coffee leaf rust (and later on coffee berry disease) for the creation of resistant varieties to both diseases
As Portugal is not a coffee growing country and the pathogens are specific of
coffee plants, their introduction poses no danger to national agriculture
CIFC was created in 1955 as part of Junta de Investigações Científicas do Ultramar (JICU), later
Instituto de Investigação Científica Tropical (IICT).
CIFC activities were included in LEAF (January 2015), while still being a research unit of IICT
CIFC was integrated in the Instituto Superior de Agronomia/UL in August, 2015

Pathogenicity Surveys & Screening of Disease Resistance
C. kahawae isolates (from several African
regions) were characterized (aggressiveness,
vegetative compatibility, isoenzymes and
molecular polymorphism)
The screening tests allowed to select coffee
genotypes with different levels of resistance
to C. kahawae to be used in the breeding
programmes
A decisive step forward in the research
programme of the CIFC was the discovery,
in the late 1950´s, of the Timor Hybrid
(HDT), a spontaneous natural hybrid
between Arabica and Robusta
More than 50 H. vastatrix races
(from different coffee growing
countries) were characterized
Some HDTs , with resistance to all known
rust races, were used as sources of
resistance in the breeding programmes
Pathogenicity Surveys & Screening of Disease Resistance
More than 90% of Arabica coffee varieties resistant to rust grown in different
coffee growing countries were created from studies carried out at CIFC

Pathogen Genetic Diversity and Evolution
Main goals: Understand population genetic structure and dynamics, host adaptation
and virulence evolution in H. vastatrix and C. kahawae, and identify molecular
markers associated with specific pathotypes.
• Identification of a geographically related genetic
structuring in Ck and its centre of origin, and proposal
of a new hypothesis of speciation through host-jump
• Uncovering of host-related genetic variation and
evidences of introgression in Hv
Coffee Resistance
Main goal: Understanding coffee resistance mechanisms to H. vastatrix and C.
kahawae to find putatively linked biomarkers to be used in the breeding programmes
Early plant responses associated: HR, accumulation of
phenolic-like compounds and up-regulation of genes
and proteins putatively involved in plant defenses
Fungal Effectors
Main goal: To understand H. vastatrix and C. kahawae infection mechanisms and to
identify fungal effectors and coffee targets, for marker assisted selection
•Genome sizes: Ck (79,5 Mbp) ; Hv (797 Mbp)
•Identification of minichromosome profiles of Ck isolates with
different aggressiveness
•Activation of genes encoding putative effectors at different stages
of the infection process in susceptible and resistant coffee plants

Conclusions and Perspectives
The gradual loss of resistance in some varieties due to the
appearance of new and more virulent Hv races, as well as
the current epidemics in Central America is leading
research institutions from coffee growing countries to
continuously seek CIFC´s support for the discovery and
characterization of new sources of resistance
To answer these requests, CIFC is giving priority to the re-evaluation of resistant coffee
genotypes (CIFC ’s collection and from international partners) with the new rust races.
This strategy also includes the joint research approach for better understanding the
coffee resistance mechanisms along with the characterization of pathogen effectors and
genetic variability, as an informed base to breed efficiently for durable resistance
