Partial Resistance to Soybean Rust in Diverse Soybean Germplasm Under Field Conditions in Uganda

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
312 soybean genotypes screened for rust resistance in Uganda. Consistent partial resistance identified in both MG1 and MG2. Rust index is highly heritable and strongly correlated with lesion type. Low G × E in MG1 indicates stable resistance expression. Top genotypes identified for breeding rust‐resistant African cultivars. ABSTRACT Soybean rust (SBR),

Secondary Metabolites of Calonectria hemileiae Inhibit Hemileia vastatrix Urediniospore Germination: Evidence for Chemical Mediation in a Mycoparasitic Interaction

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Calonectria hemileiae, an antagonist of the coffee leaf rust pathogen Hemileia vastatrix, produces low‐molecular weight secondary metabolites that inhibit urediniospore germination. These metabolites likely mediate interfungal interactions and show potential for the development of biofungicides against coffee leaf rust.

Identifying and managing Cercospora leaf blight in soybean: From scouting to best management practices

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Maximizing soybean [Glycine max (L.) Merr.] yield requires effective management of Cercospora leaf blight (CLB), a significant foliar disease that can reduce productivity and grain quality. The impact of CLB is particularly notable in regions such as the mid‐southern United States, where species of Cercospora, predominantly C. cf. flagellaris,

A new chitinase-like xylanase inhibitor protein (XIP) from coffee (Coffea arabica) affects Soybean Asian rust (Phakopsora pachyrhizi) spore germination

BMC Biotechnology, 2011
Background Asian rust (Phakopsora pachyrhizi) is a common disease in Brazilian soybean fields and it is difficult to control. To identify a biochemical candidate with potential to combat this disease, a new chitinase-like xylanase inhibitor protein (XIP)

Integrative genomic analyses reveal candidate genes for the Ur‐3 and Ur‐7 rust resistance loci in common bean

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Bean rust, caused by Uromyces appendiculatus, severely limits the productivity of common bean (Phaseolus vulgaris L.), an essential source of protein and micronutrients in human diets worldwide. Durable disease management relies primarily on host resistance; however, the molecular architecture of several key rust resistance loci remains ...

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3573-3593, June 2026.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

Suppression or Activation of Immune Responses by Predicted Secreted Proteins of the Soybean Rust Pathogen Phakopsora pachyrhizi

Molecular Plant-Microbe Interactions, 2018
Rust fungi, such as the soybean rust pathogen Phakopsora pachyrhizi, are major threats to crop production. They form specialized haustoria that are hyphal structures intimately associated with host-plant cell membranes.

Fungicide Resistance Profile of Monilinia fructicola and Monilinia laxa Isolates From Commercial Peach and Nectarine Orchards in the Ebro Valley, Spain

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Combining phenotypic sensitivity testing with molecular characterization, we identify diverse tolerant Monilinia phenotypes in Spanish orchards. The integration of genetic insights with fungicide response reveals early resistance development requiring updated control strategies.
