The Transcription Factors HbWRKY29 and HbPTI5 cooperatively enhance rubber tree resistance to powdery mildew

Molecular Plant Pathology, Volume 27, Issue 6, June 2026.
Upon Erysiphe quercicola infection, rubber HbWRKY29 is rapidly induced and physically interacts with HbPTI5 to trigger HR. HbWRKY29 binds the HbPTI5 promoter (W‐box), enhancing HbPTI5 expression, which activates HbTLP1 expression, leading to reinforced defence.

Cytological and Molecular Analysis of the Hordeum vulgare-Puccinia triticina Nonhost Interaction

Molecular Plant-Microbe Interactions, 2003
Cultivated barley, Hordeum vulgare L., is considered to be a nonhost or intermediate host species for the wheat leaf rust fungus Puccinia triticina. Here, we have investigated, at the microscopic and molecular levels, the reaction of barley cultivars to ...

Virulence of Puccinia triticina on Wheat in Nebraska during 1997 and 1998 [PDF]

Plant Disease, 2001
Urediniospore isolates of Puccinia triticina were obtained from wheat leaf collections made in three wheat-growing regions in Nebraska in 1997 and in four regions in 1998. Using 16 Thatcher lines that are near-isogenic for leaf rust resistance, 17 virulence phenotypes were found among 121 single uredinial isolates in 1997, and 42 virulence phenotypes ...

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

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3616-3633, June 2026.
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 ...

A landscape-scale field survey demonstrates the role of wheat volunteers as a local and diversified source of leaf rust inoculum

Scientific Reports, 2023
Deploying disease-resistant cultivars is one of the most effective control strategies to manage crop diseases such as wheat leaf rust, caused by Puccinia triticina. After harvest, this biotrophic fungal pathogen can survive on wheat volunteers present at

Physiologic Specialization of Puccinia triticina on Wheat in the United States in 2015 [PDF]

Plant Disease, 2017
Leaves of wheat infected with the leaf rust fungus, Puccinia triticina, were obtained from farm fields and breeding plots at experimental stations in the Great Plains, Ohio River Valley, and southeastern states in 2015 in order to identify virulence phenotypes prevalent in the United States in different wheat growing regions.

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

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3723-3738, June 2026.
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.

Physiologic Specialization of Puccinia triticina on Wheat in the United States in 2004 [PDF]

Plant Disease, 2006
Collections of Puccinia triticina were obtained from rust-infected wheat leaves by cooperators throughout the United States and from surveys of wheat fields and nurseries in the Great Plains, Ohio Valley, southeast, California, and Pacific Northwest, in order to determine the virulence of the wheat leaf rust population in 2004.

A new soft red winter wheat cultivar adapted to the U.S. Southeast Region: ‘GA 09377‐16LE18’

Journal of Plant Registrations, Volume 20, Issue 2, May/August 2026.
Abstract Soft red winter wheat (SRWW; Triticum aestivum L.) is a major crop grown in the U.S. Southeast Region (the Southeast) that contributes significantly to wheat growers and the industry. However, wheat is challenged by many stresses, resulting in substantial losses in yield and quality.
