Identification of QTLs involved in the resistance to South American leaf blight (Microcyclus ulei) in the rubber tree [PDF]
Theoretical and Applied Genetics, 2000 South American leaf blight (SALB) is a disease of the rubber tree caused by the fungus Microcyclus ulei. Quantitative trait loci (QTLs) for resistance were mapped using 195 F1 progeny individuals derived from the cross between a susceptible cultivated clone, PB260, and a resistant clone, RO38, derived from interspecific hybridization.

Bypassing of a polygenicMicrocyclus uleiresistance in rubber tree, analyzed by QTL detection
New Phytologist, 2006SummaryGenetic resistance components of theHevea brasiliensis × H. benthamianaRO 38 cultivar toMicrocyclus uleidisease were investigated by inoculating isolates which succeeded in partially or completely infecting genotypes of a mapping population.Progeny of a cross between RO 38 and a susceptible cultivar was inoculated under controlled conditions ...

Occurrence of eight races of Microcyclus ulei on Hevea rubber in Bahia, Brazil
Transactions of the British Mycological Society, 1986Conidia of Microcyclus ulei from infected leaves of twelve clones of Hevea , including H. brasiliensis and its hybrids with H. benthamiana , were inoculated to leaf disks of 19 clones of diverse genetic background. From the results, eight physiologic races of M. ulei were distinguished.

Molecular mapping of genes conferring field resistance to South American Leaf Blight (Microcyclus ulei) in rubber tree [PDF]
Theoretical and Applied Genetics, 2003 The South American Leaf Blight (SALB), caused by the fungus Microcyclus ulei, is the major rubber tree disease in all Central and South America. A population of 192 progeny individuals derived from a cross between a resistant clone and a susceptible cultivated clone was planted in a field trial in French Guiana in order to evaluate the resistance ...

South American leaf blight of Hevea brasiliensis: spore dispersal of Microcyclus ulei
Annals of Applied Biology, 1976SUMMARYTrapping of ascospores and conidia of Microcyclus ulei among young trees of Hevea brasiliensis in Trinidad from May 1973 to May 1975 snowed that ascospores occurred throughout the year whilst conidia were present only during the wet season. Peak ascospore concentrations occurred in August and November during the wet season, the latter peak being

Factors affecting discharge, germination and viability of spores of Microcyclus ulei
Transactions of the British Mycological Society, 1976Ascospores of Microcyclus ulei are forcibly discharged in rapid succession when leaves are wetted at sub-ambient temperatures (14 °C). Leaves which fall during wintering discharge ascospores readily after rain. Ascospores are released from green leaves throughout the dry season.

Characterization of polymorphic microsatellite markers for Microcyclus ulei, causal agent of South American leaf blight of rubber trees [PDF]
Molecular Ecology Notes, 2004 AbstractSouth American leaf blight caused by the ascomycete Microcyclus ulei is the most harmful disease of the rubber tree in Latin America and a potential threat to Asiatic and African natural rubber production. Until now, the variability of this fungus was assessed through observation of pathogenicity of isolates on a range of rubber tree clones ...

SummaryYoung leaves of different rubber‐tree clones were inoculated withMicrocyclus uleiunder controlled conditions. Under ultraviolet light, intense blue fluorescent light was emitted from the penetration site 6 h after inoculation. The speed of the appearance of this fluorescence was related to the degree of resistance of the clones: 12–36 h in ...
