Physiologic Specialization ofPuccinia triticinain Canada in 1997 [PDF]

Plant Disease, 1999
In 1997, leaf rust of wheat (Triticum aestivum), caused by Puccinia triticina, was widespread throughout the prairies of western Canada. Warm summer temperatures with frequent dew periods favored spread of the disease in wheat fields in Manitoba, Saskatchewan, and Alberta.

The Automation of Hyperspectral Training Library Construction: A Case Study for Wheat and Potato Crops

Remote Sensing, 2021
The potential of hyperspectral measurements for early disease detection has been investigated by many experts over the last 5 years. One of the difficulties is obtaining enough data for training and building a hyperspectral training library.

Comparative gene expression analysis of susceptible and resistant near-isogenic lines in common wheat infected by Puccinia triticina [PDF]

, 2010
Gene expression after leaf rust infection was compared in near-isogenic wheat lines differing in the Lr10 leaf rust resistance gene. RNA from susceptible and resistant plants was used for cDNA library construction.

Especialização fisiológica de Puccinia triticina no Brasil em 2002 [PDF]

Fitopatologia Brasileira, 2006
A ferrugem da folha é uma das principais doenças que afetam a cultura do trigo (Triticum aestivum). Nas regiões tritícolas da Argentina, Brasil, Paraguai, Uruguai e Bolívia têm ocorrido todos os anos epidemias da moléstia, as quais podem ocasionar perdas de até 50% no rendimento de grãos de cultivares suscetíveis, se não for efetuado controle com ...

Molecular Detection of the Adult Plant Leaf Rust Resistance Gene Lr34 in Romanian Winter Wheat Germplasm [PDF]

, 2015
Wheat continues to be one of the most cultivated cereals in the world, and also in Romania. Leaf rust caused by Puccinia triticina reduces the wheat yield and grains quality worldwide.

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

The miR171a‐TaSCL6‐1 Module Acts Downstream of miR164‐Targeted TaNAC21/22 to Regulate Leaf Rust Resistance in Wheat

Plant Biotechnology Journal, EarlyView.
ABSTRACT Wheat leaf rust, caused by Puccinia triticina, poses a significant threat to global wheat production. MicroRNAs (miRNAs) are critical regulators of plant growth, development and stress responses; however, their role in wheat resistance to leaf rust remains poorly understood.

Genetic Variation and Virulence on Lr26 in Puccinia triticina [PDF]

Phytopathology®, 2004
The genetic relationships between isolates of Puccinia triticina virulent on wheat with the Lr26 resistance gene were studied. The diversity within and between isolates of P. triticina from Israel, Europe, and the United States was determined by virulence on near-isogenic Thatcher lines and by random amplified polymorphic DNA.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
