Résumé :
Attached and detached leaves of 60 potential host species were inoculated in the greenhouse and laboratory with aeciospores of Cronartium ribicola J.C. Fisch. from six Finnish locations and of Cronartium flaccidum (Alb. & Schw.) Wint. from 20 locations in Finland and Sweden in 2011. Candidate hosts represented 16 plant families: Solanaceae, Verbenaceae, Asclepiadaceae, Grossulariaceae, Paeoniaceae, Balsaminaceae, Gentianaceae, Scrophulariaceae, Loasaceae, Tropaeolaceae, Acanthaceae, Myricaceae, Phrymaceae, Plantaginaceae, Orobanchaceae, and Apocynaceae. Inoculations of C. flaccidum produced uredinia after 2 weeks and (or) telia after 4 weeks of incubation on 25 hosts. Inoculation trials identified several new hosts for C. flaccidum in Fennoscandia, namely Impatiens balsamina, Swertia fedtschenkoana, Loasa tricolor, Myrica gale, Verbena canadensis, Saxifraga spp., Paeonia obovata, and Veronica daurica. Myricaceae and Saxifragaceae represent new host families for these rusts. Cronartium ribicola formed uredinia or telia on 10 species: Ribes spp. (7 species/cultivars), Pedicularis palustris subsp. palustris, Bartsia alpina, and Loasa triphylla. Results suggest wider alternate host ranges for both C. flaccidum and C. ribicola than previously recognized. Spores were virulent regardless of their source location, suggesting a lack of host-specificity among Fennoscandian populations of Cronartium.

Résumé :
We explored the potential of the North European flora and some garden plants growing naturally outside Europe to support a reservoir of pine stem rusts. Live plants and detached leaves of 35 species in 16 families (Solanaceae, Verbenaceae, Grossulariaceae, Paeoniaceae, Balsaminaceae, Gentianaceae, Scrophulariaceae, Loasaceae, Tropaeolaceae, Acanthaceae, Myricaceae, Phrymaceae, Plantaginaceae, Orobanchaceae, Apocynaceae, and Fagaceae) were inoculated in the greenhouse and (or) laboratory with aeciospores of Cronartium ribicola J.C. Fisch. and Cronartium flaccidum (Alb. & Schwein) G. Winter in 2010. Cronartium flaccidum produced uredinia and (or) telia in 14 species in nine families, 11 of which represent new alternate hosts in Finland and nine also elsewhere (excluding Nemesia versicolor and Tropaeolum majus L.): Euphrasia stricta D. Wof. ex J.F. Lehm., N. versicolor E. Mey. ex Benth., Nemesia strumosa Benth., Verbena × hybrida Voss., Verbena officinalis L., Veronica longifolia L., Impatiens glandulifera Royle, T. majus, Loasa triphylla Juss., Asclepias incarnata L., and Bartsia alpina L. Cronartium ribicola formed fruitbodies in nine species and cultivars in five families, five of which are new alternate hosts for this species in Finland and also elsewhere: Mentzelia lindleyi Torr. & A. Gray, A. incarnata, B. alpina, L. triphylla, and T. majus. Both species of Cronartium infected four alternate hosts, each in its own family. The alternate host range of each Cronartium was wider than expected and wider than that previously described. In local natural forests, Euphrasia , Veronica , and Bartsia (in northern Finland) are potential hosts that are common and may be able to spread these rusts. The recently established ornamental I. glandulifera could provide the means to spread C. flaccidum to Scots pine ( Pinus sylvestris L.) in southern Finland, and species of Mentzelia may be important for the spread of C. ribicola.

Résumé :
Cultures of Cronartium flaccidum were established from aeciospores collected from Pinus halepensis and Pinus laricio growing at four Italian sites: one southern and one northern (north-central) site for each host species. The two southern and the two northern sites were also geographically separate. Colonies were incubated for 7 months and compared for growth rates, macroscopic and microscopic features of the colonies, presence or absence of sporulation, and spore type. Germ tubes exhibited negative geotropism and were light sensitive. Colonies from southern isolates generally remained white and fast growing throughout, whereas colonies from northern isolates tended to turn orange and become slow growing. The faster growing white colonies could be maintained in the same Petri dishes without undergoing morphological change for the entire incubation period, but the slow-growing orange colonies had to be transferred to fresh medium every month or they became covered with short, hyaline hyphae. Immature aeciospores, typical mature aeciospores, and teliospore-like bodies formed in culture. Spore ontogeny, capacity to be successfully subcultured, growth rate, and other evidence indicated the southern and north-central Italian isolates were distinct. The host species was not a factor in culture variation. The importance of the axenic technique in relation to rust disease research is discussed. Keywords: rust, in vitro growth, cultural variation, sporulation.

Résumé :
Distribution and frequency of Cronartium flaccidum telia were investigated on Melampyrum spp. growing wild in 355 Scots pine stands in Finland. Telia were found for the first time on M. arvense in Finland and for the first time on M. pratense and M. nemorosum in natural forests anywhere. Cronartium flaccidum telia were found in 22% of all stands with M. sylvaticum, 3% of stands with M. pratense, 12% of stands with M. nemorosum, 100% of stands with M. arvense, and 0% of stands with M. cristatum. Melampyrum spp. with telia were mostly found in northern Finland. The proportions of stands with telia and of plants with telia per stand, the frequency of telia-bearing leaves per plant, and the average number of telia per leaf were greater for M. sylvaticum than for most of the other Melampyrum species. In severely affected pine stands, telia were frequent on M. sylvaticum, but scarce or lacking on M. pratense. On sites with M. sylvaticum, the respective proportion of telia-bearing plants was significantly higher in young development classes and severely diseased stands than in older development classes and slightly damaged stands. The results suggest that the main host of C. flaccidum is M. sylvaticum in northern Finland.

Texte intégral
Résumé :
An integrated approach, based on the analysis of both molecular and morphological characters, has led to the unambiguous detection and identification of the rust hyperparasite Cladosporium tenuissimum from aeciospores of the two-needle pine rust fungi Cronartium flaccidum and Peridermium pini. Cladosporium tenuissimum was first detected from contaminated field-collected rust spores using the polymerase chain reaction (PCR) method. The similar-sized amplified DNA of the parasite was then separated from rust DNA using electrophoretic migration, reamplified separately with the nested PCR, and sequenced. Sequence comparison in the data banks enabled the hyperparasite to be recognised as a species of Cladosporium. Molecular detection was followed by conventional identification, obtained by plating rust spores on potato dextrose agar, a selective medium for rusts, since they are unable to grow on such a common substrate, and isolating the hyperparasite in pure culture. It was subsequently identified as C. tenuissimum. Traditional identification would not have been possible without guidance from the molecular data, which focused attention on the mycoparasite. Macro- and micro-scopic features of colonies are also given to help with future identification on spore sources from other geographical areas and, if this should occur, future identification on other rusts.Key words: mycoparasitism, PCR detection, traditional detection, Cladosporium tenuissimum, Cronartium flaccidum, Peridermium pini.

Résumé :
This paper describes 15 species of fungi in the order Uredinales, causing the diseases known as "rusts". These fungi develop as obligate parasites and cause very dangerous diseases on cultivated plants. Among the "rusts" occurring on the trees, the following rusts are of special economic significance Melampsorella caryophyllacearum (rust on fir), Cronartium flaccidum (rust on two-needle pines) and Melampsora species (rusts on poplars). Fungi Chrysomyxa pirolata, Pucciniastrum epilobii, Gymnosporangium clavariiforme and G. tremelloides have been identified for the first time in Serbia.
