Identification and mapping of quantitative trait loci for Fusarium head blight resistance in a synthetic hexaploid × hard red spring wheat population

The Plant Genome, Volume 18, Issue 3, September 2025.
Abstract Fusarium head blight (FHB), caused by Fusarium graminearum Schwabe, is one of the most devastating diseases in wheat (Triticum aestivum L.). The synthetic hexaploid wheat line Largo was developed from a cross between the durum wheat [T. turgidum ssp. durum (Desf.) Husn.] variety Langdon and the Aegilops tauschii Cosson accession PI 268210, and

Efficacy and mapping of resistance to Mycosphaerella graminicola in wheat [PDF]

, 2011
Wheat is the most important food and feed crop, contributing about 19% of the required human dietary energy. The annual growth rate of the global cereal production -including wheat- is below one per cent.

Wheat Diseases in Republic of Macedonia

Journal of Agriculture and Plant Sciences, 2013
During May and June 2006 and 2007, the health condition of the wheat and barley crops in the Republic of Macedonia was checked. The monitoring was done in the area of: Skopje, Stip, Kocani, Kumanovo, Probistip, St. Nikole and Bitola.

Environmental Requirements for Germination and Appressorium Formation of Ascospores and Conidia of Phyllosticta citricarpa, the Causal Agent of Citrus Black Spot

Plant Pathology, Volume 74, Issue 7, Page 2108-2120, September 2025.
Cardinal temperatures for both Phyllosticta citricarpa spore germination were estimated as ~10ºC (minimum) and ~40ºC (maximum), and the optimum temperatures were ~30ºC for ascospores and ~24ºC for conidia. ABSTRACT Phyllosticta citricarpa produces ascospores and conidia that infect citrus tissues and cause citrus black spot (CBS).

A comparative genome analysis of Cercospora sojina with other members of the pathogen genus Mycosphaerella on different plant hosts

Genomics Data, 2017
Fungi are the causal agents of many of the world's most serious plant diseases causing disastrous consequences for large-scale agricultural production. Pathogenicity genomic basis is complex in fungi as multicellular eukaryotic pathogens. Here, we report

Insights into a genomics‐based pre‐breeding program in wheat

Crop Science, Volume 65, Issue 4, July/August 2025.
Abstract Continuous intercrossing of the best‐performing wheat (Triticum aestivum L.) elite lines has resulted in genetic gains for a wide range of traits. However, this approach can also reduce genetic diversity, which potentially limits the long‐term genetic improvement.

Long-term relationships between environment and abundance in wheat of Phaeosphaeria nodorum and Mycosphaerella graminicola [PDF]

, 2008
Relationships between weather, agronomic factors and wheat disease abundance were examined to determine possible causes of variability on century time scales. In archived samples of wheat grain and leaves obtained from the Rothamsted Broadbalk experiment

Update on mechanisms of azole resistance in Mycosphaerella graminicola and implications for future control

, 2013
This review summarises recent investigations into the molecular mechanisms responsible for the decline in sensitivity to azole (imidazole and triazole) fungicides in European populations of the Septoria leaf blotch pathogen, Mycosphaerella graminicola ...

Brown Spot of Rice: Worldwide Disease Impact, Phenotypic and Genetic Diversity of the Causal Pathogen Bipolaris oryzae, and Management of the Disease

Plant Pathology, Volume 74, Issue 4, Page 908-922, May 2025.
The literature shows that brown spot caused by Bipolaris oryzae is a re‐emerging disease with a major impact on rice production worldwide, and the pathogen population diversity and structure are consistent with sexual reproduction. ABSTRACT Rice brown spot caused by Bipolaris oryzae (syn.
