Wheat leaf rust, caused by Puccinia triticina, is one of the most devastating diseases in common wheat ( Triticum aestivum) globally. Using resistant lines is the most cost-effective and safe disease control method. Eighty-three wheat lines from China and 36 differential lines, mainly near-isogenic lines with known leaf rust resistance ( Lr) genes in ...

Abstract The objective of this study was to characterize yellow (stripe) rust resistance gene(s) in 52 commercial wheat cultivars from Yunnan Province in China, and to provide information for their rational deployment in field. Seedlings of wheat cultivars were inoculated with 25 differential isolates of Puccinia striiformis from foreign and home to ...

Linear atrophoderma of Moulin: postulation of mosaicism for a predisposing gene
Journal of the American Academy of Dermatology, 2003Hyperpigmented atrophoderma arranged in a pattern following the lines of Blaschko and appearing during childhood or adolescence on the trunk or the limbs is a characteristic feature of linear atrophoderma of Moulin. We review 15 published reports and describe 4 additional cases.

Recombination between the postulated CCD/MHE/MHS locus and RYR1 gene markers
Clinical Genetics, 1996Malignant hyperthermia (MH) susceptibility is considered a subclinical myopathy or a pharmacogenetic trait, and is believed to be closely associated with central core disease (CCD). Data support the notion that MH susceptibility is heterogeneous, with the ryanodine receptor 1 (RYR1) locus on chromosome 19 being one locus harboring a gene that can cause

Postulation of leaf rust resistance genes in Iranian wheat cultivars and breeding lines
Canadian Journal of Plant Pathology, 2011Abstract Knowledge of the number and identity of the leaf rust resistance genes in wheat breeding material is essential for maximizing resistance in future-bred cultivars. The objective of this study was to test for seedling resistance genes to Puccinia triticina potentially present in 36 Iranian wheat cultivars and breeding lines, using 13 prevalent ...

Postulation of resistance genes to barley diseases in heterogeneous varieties
Biologia, 2011Resistance to causal agents of diseases is an important varietal characteristic that influences the management practice of crop plants and thus production costs of commodities. At present, almost all European barley varieties possess at least one major gene for resistance to powdery mildew.

Postulation of leaf‐rust resistance genes in Czech and Slovak barley cultivars and breeding lines
Plant Breeding, 2000AbstractLeaf‐rust resistance (Rph) genes in 61 Czech and Slovak barley cultivars and 32 breeding lines from registration trials of the Czech Republic were postulated based on their reaction to 12 isolates of Puccinia hordei with different combinations of virulence genes.

GeneFisher--software support for the detection of postulated genes.
Proceedings. International Conference on Intelligent Systems for Molecular Biology, 1996When a family of genes from closely related organisms is known, there is a certain change to extract the corresponding gene from the genome of another related organism. This can be done by polymerase chain reaction, provided that a pair of suitable primers can be designed.

Postulated Genes for Resistance to Stripe Rust in Selected CIMMYT and Related Wheats
Plant Disease, 1989Infection type data were used to postulate the presence of stripe rust seedling resistance genes in 20 CIMMYT and related bread wheats. Yr3, Yr6, Yr7 and Yr9 were hypothesized to be present in 12 lines, either alone or in combination. The isolates used also indicated the presence of additional unknown seedling resistance genes. Four lines produced only
