Tan Spot Disease of Wheat : race characterization
Tan spot, one of the most important diseases of wheat, is caused by Pyrenophora tritici-repentis, a necrotrophic fungus which survives in wheat straw. Methods of disease control include fungicide application, crop rotation, and the use of resistant cultivars; however, in Brazil there are no cultivars in the market with a good level of resistance. In North America, a system of race identificatio...
متن کاملThe control of tan spot of wheat (caused by Pyrenophora tritici-repentis: a possible emerging disease in New Zealand
Pyrenophora tritici-repentis, the cause of tan spot of wheat was first recorded in New Zealand in 1979, but only on wheat seed. However, this pathogen has recently been recorded as causing possible yield losses in isolated crops. A small plot trial set up in a central Canterbury crop of cv. Saracen tested several fungicides alone or in mixtures. Control was not entirely effective since tan spot...
متن کاملLeaf Spot of Field Corn Caused by Pseudomonas Andropogonis
A leaf spot of field corn was shown to be caused by the bacterium Pseudomonas andropogonis. Leaf spot symptoms were observed over 3 years in several States. Inoculation of corn by vacuum infiltration of the bacteria was necessary to reproduce field symptoms. Plant Dis. Reptr. 62: 213-216. A bacterial leaf spot disease of different cultivars of field corn was observed in early summer of 1973, 19...

Spot pattern of Leopard Danio is caused by the mutation in zebrafish connexin41.8 gene
متن کاملSpot pattern of leopard Danio is caused by mutation in the zebrafish connexin41.8 gene.
Leopard, a well-known zebrafish mutant that has a spotted skin pattern instead of stripes, is a model for the study of pigment patterning. To understand the mechanisms underlying stripe formation, as well as the spot variation observed in leopard, we sought to identify the gene responsible for this phenotype. Using positional cloning, we identified the leopard gene as an orthologue of the mamma...
