ABSTRACT.- Leaf rust (LR) of bread wheat (Triticum aestviumL.), caused by the fungus Puccinia triticinaEriks, is one of the most important diseases in Paraguay, the Southern Cone and worldwide. The economic importance of the disease is clear considering that two or morefungicide applications are necessary to control itinsusceptible cultivars. The best strategy for the management of this disease is through genetic resistance. This research was conducted in Uruguay aiming topostulatethe LR resistance genes present in 102 lines and wheat cultivars from Paraguay,and to study their field re-sistance. The presence of 18 major resistance genes expressed at the seedling stage (Lr1,Lr2,Lr3a,Lr3bg,Lr3ka,Lr9,Lr10,Lr11,Lr16,Lr17,Lr23,Lr24,Lr26,Lr27+Lr31,Lr28,Lr30,Lr42) was postulated based on the reaction to different races of the pathogen. The adult plant resistance gene Lr34was confirmed in 26% of the materials, based on the molecular marker csLV34. This study also allowed differentiatingmaterials with field resistance that can be explained by the seedling resistance and those with adult plant resistance. Knowledge of the resistance genes present in the germplasm of breeding programs is of paramount importance to establish strategies in order toachieve effective and long-lasting resistance based mainly on the combination of race-non-specific minor genes. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.

Congenital erythropoietic porphyria (CEP) is a rare hereditary autosomal recessive disease which has never been reported in Zebu cattle. A 3-day-old Gir calf showed teeth discoloration, fever, dehydration, and dyspnea. The main gross findings were pink-colored teeth, red-brown periosteum and bone marrow, and a fluorescent bright pink coloration of the bone marrow and articular surfaces under ultraviolet light. Aggregates of periodic acid-Schiff (PAS)-stained porphyrin pigments were evident in the lungs, kidneys, and the liver. An intron 8 single-nucleotide polymorphism (SNP) in both the Gir calf and control animals, along with the absence of the uroporphyrin III synthetase (UROS) gene mutation, was observed. Most SNPs were located in the intron regions of the UROS gene without relevance for CEP. A continuous loss of genetic variability and an increase in inbreeding in some herds may be related to CEP in Gir cattle, one of the most prominent Zebu breeds worldwide. In summary, this study describes a presumptive case of CEP in a Gir calf based on clinical and pathological findings. A definitive diagnosis
would require the measurement of porphyrin levels in blood, urine, or tissues or the identification of UROS gene defects. |
