Malate Dehydrogenases in the Rusted Bean Leaf
Science, 1963Rust growth in the bean leaf was accompanied by the appearance of one new malate dehydrogenase isozyme and continuation of one otherwise lost during the development of the healthy leaf. The new isozyme was contributed by the fungus, the other by the leaf. Both enzymes were cytoplasmic proteins. Rusting caused the loss of a mitochondrial isozyme.

Wheat cultivars which have maintained resistance to leaf rust in India for the last 15-20 years carry unknown genes which are expressed at different post-seedling stages or in adult plants. At least 20 such genes have been detected through multi-race tests and tests with defined rust races at high/low temperatures and plants of varying age. These genes

Disease resistance in the genusAegilops L. — stem rust, leaf rust, stripe rust, and powdery mildew
Die Kulturpflanze, 1985Resistance of the GaterslebenAegilops collection was studied in relation to the following wheat diseases: stem rust(Puccinia graminis), leaf rust(Puccinia recondita), stripe rust(Puccinia striiformis) and powdery mildew(Erysiphe graminis). Numerous sources of complete, combined or single resistance have been detected in 487 accessions of 21Aegilops ...

The progress of leaf rust research in wheat
Fungal Biology, 2020Leaf rust (also called brown rust) in wheat, caused by fungal pathogen Puccinia triticina Erikss. (Pt) is one of the major constraints in wheat production worldwide. Pt is widespread with diverse population structure and undergoes rapid evolution to produce new virulent races against resistant cultivars that are regularly developed to provide ...

Triticale diversity in leaf rust resistance
Russian Agricultural Sciences, 2009An evaluation of 416 triticale accessions from the Vavilov All-Russian Research Institute of Plant Industry (VIR) collection reveals a great diversity of forms in the character of leaf rust resistance. A nonuniform distribution of resistant phenotypes is noted in groups differing in ploidy level and geographic origin.

Field Phenotyping of Wheat Leaf Rust and Stem Rust
The three rust diseases, yellow (stripe) rust, black (stem) rust, and brown (leaf) rust are major challenges to wheat production, causing annual global yield losses of approximately 15 million tons valued at US$ 2.9 billion. Genetic resistance, including race-specific genes (R genes) and adult plant resistance (APR), is the primary control strategy ...Naeela, Qureshi +3 more

Inheritance of leaf rust and stem rust resistance in 'Roblin' wheat
Genome, 1993The Canadian common wheat (Triticum aestivum L.) cultivar 'Roblin' is resistant to both leaf rust (Puccinia recondita Rob. ex. Desm.) and stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. and E. Henn.). To study the genetics of this resistance, 'Roblin' was crossed with 'Thatcher', a leaf rust susceptible cultivar, and RL6071, a stem rust ...

Leaf Rust and Stripe Rust Resistance Genes Derived from Aegilops Sharonensis
Euphytica, 2006Linked leaf and stripe rust resistance genes introgressed into hexaploid wheat from Aegilops sharonensis provided protection in the seedling stage to a wide range of pathotypes of the two diseases. Monosomic and telosomic analyses showed that the resistance genes occur on wheat chromosome 6A.

Influence of wheat leaf position on leaf rust severity
Euphytica, 1990The relation between flag leaf position and leaf rust severity was investigated in field experiments. Different leaf angles were obtained by attaching ends of flag leaves to strings stretched at different heights along wheat rows. Leaves with angles between lamina and stem of 0° and 45° were significantly less diseased than leaves with horizontal and ...

Crop Science, 2019
Stripe rust, leaf rust, and the leaf spot complex are economically important diseases of wheat (Triticum aestivum L.) in western Canada, and genetic host resistance is the most successful management strategy. This study was conducted to identify quantitative trait loci (QTL) associated with these diseases and to provide wheat breeders with sources of ...
