Effects of Puccinia triticina differentials and suggestion for creating a new set [PDF]

Ratarstvo i Povrtarstvo, 2010
Previous explanations of wheat and Puccinia triticina interactions are presented. New ones suggested the stable effects of the resistance genes on growth characters and realized the opportunity for creating the new set of parasite population ...

Identification of a leaf rust resistance gene in the Chinese wheat line LB0288

Czech Journal of Genetics and Plant Breeding, 2015
Leaf rust (LR), caused by Puccinia triticina (Pt), is worldwide one of the most spread diseases in common wheat (Triticum aestivum L.). With the objective of identifying and mapping new genes for resistance to leaf rust, F1 and F2 plants from a cross ...

Effect of elevated atmospheric CO2 level on the abiotic and biotic stress tolerance of cereals [PDF]

, 2013
Effect of elevated CO2 level (EC) was studied on the tolerance of cereals to elevated temperature and drought and on the resistance of wheat to fungal diseases. In general, elevated growth temperature did not affect final grain size, thus having less

Durable resistance to Puccinia triticina by accumulation of resistance genes

Genetika, 2009
The individual use of single race-specific resistance genes with major phenotypic effects has rarely provided lasting resistance. However, breeding and combining or pyramiding of resistance genes into individual cultivars has had considerable success, particularly in situations in which the pathogen does not reproduce sexually, as in the case of wheat ...

Clonalité et sélection par l'hôte chez Puccinia triticina

, 2006
Des études antérieures ont permis de montrer que les populations de rouille brune du blé (Puccinia triticina, basidiomycète dicaryotique) se reproduisent de façon clonale et se structurent en fonction de la plante hôte. Sous l'angle de la génétique des populations, la structure clonale se traduit par des profils multilocus répétés et de forts ...

Adult plant resistance to leaf rust (Puccinia triticina) in some Indian bread wheat (Triticum aestivum) accessions bearing leaf tip necrosis

The Indian Journal of Agricultural Sciences, 2014
Of the 2200 germplasm accessions of Triticum aestivum L. screened under field condition against leaf rust (Puccinia triticina), 1526 exhibited symptom of leaf tip necrosis (LTN). Ninety eight per cent of accessions showing LTN revealed reduced leaf rust

Functions of LR genes beside reduction of Puccinia triticina [PDF]

, 2013
Geni za specifičnu otpornost prema prouzrokovaču lisne rđe pšenice (Lr) smanjivali su rast sledećih delova stabla (SAGR) za 0,01-0,03 u poređenju sa osnovnom sortom Tačer ili Lr 22b linijom. RAR, odnosno podeljen sadržaj azota u korenu sa zbirom navedene vrednosti i one u nadzemnom delu u stadijumu sejanaca, bio je umanjen u odnosu na poslednje ...

Prooxidáns és antioxidáns növényi gének a nem-gazda betegségrezisztenciában - funkció meghatározás géncsendesítéssel = Prooxidant and antioxidant plant genes in non-host resistance - functional identification by gene silencing [PDF]

, 2010
Prooxidáns, antioxidáns és programozott sejthalállal kapcsolatos gének mRNS-szintű kifejeződését vizsgáltuk az ún. nem-gazda rezisztenciában (=rezisztencia a más növényfajokat fertőző kórokozókkal szemben), vírus-, baktérium- és gomba kórokozókkal ...

Lr34-Mediated Leaf Rust Resistance in Wheat: Transcript Profiling Reveals a High Energetic Demand Supported by Transient Recruitment of Multiple Metabolic Pathways

Molecular Plant-Microbe Interactions, 2008
The wheat gene Lr34 confers partial resistance to all races of Puccinia triticina, the causal agent of wheat leaf rust. However, the biological basis for the exceptional durability of Lr34 is unclear. We used the Affymetrix GeneChip Wheat Genome Array to
