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 ...

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

Inheritance of Slow‐Rusting Resistance to Leaf Rust in Wheat
Crop Science, 1992Race‐specific resistance of wheat (Triticum aestivum L. emend. Thell.) to leaf rust (Puccinia recondita f. sp. tritici) is often short‐lived. Slow‐rusting resistance has been reported to be a more durable type of resistance. To exploit the advantages of this durability, genetic analysis of slow rusting is essential.

Wheat leaf epicuticular characteristics as rust inhibitors
Journal of Environmental Science and Health, Part B, 1996Abstract Wheat (Triticum aestivum L.) trichomes influence wheat leaf rust (Puccinia recondita Rob. ex Desm.) germling elongation as a function of the external element (i.e. ‐ Ca, Si, P, CI) concentration. Basal cells of multicellular trichomes have a high Ca content; and, Ca2+ has been shown to inhibit elongation of primary roots.

Slow leaf rust development on durum wheat
Canadian Journal of Botany, 1977Several durum wheat (Triticitm durum) cultivars exhibiting susceptible or moderately susceptible reactions to the leaf rust fungus (Puccinia recondita tritici) were evaluated for slow rusting. Percentage severity and reactions for P. recondita tritici on each cultivar were evaluated periodically after initial infection.

Leaf rust responsive miRNA and their target genes in wheat
Functional & Integrative Genomics, 2022Small RNA sequencing (sRNA-seq) and degradome analysis were used for the identification of miRNAs and their target host genes in a pair of near-isogenic lines (NILs), which differed for the presence of leaf rust resistance gene Lr28. The study led to identification of (i) 506 known and 346 novel miRNAs; and (ii) 5054 target genes including 4557 in ...

Environmental stability of partial resistance in spring wheat to wheat leaf rust
Euphytica, 1989Five spring wheat cultivars differing in partial resistance (PR) to wheat leaf rust were tested at Wageningen (the Netherlands) on a sandy and a clay site, El Batan (CIMMYT, Mexico) and Ponta Grossa (Brazil) over two years. The cultivars were Skalavatis 56, Little Club (both very susceptible), Westphal 12A, Akabozu and BH 1146 (all three with high ...

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

LEAF RUST RESISTANCE OF TRANSEC WHEAT
Canadian Journal of Genetics and Cytology, 1969The same single dominant factor in the wheat-rye translocation line Transec controls resistance to Australian leaf rust strains in the seedling and adult plant stages. Transec did not derive the major factor for adult plant resistance from its Chinese Spring parent. The two factors which are both on chromosome 4A appear to be loosely linked.

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 ...
