False mildew is a serious disease of safflower crops in the Yaqui Valley, Mexico, and is caused by infection with a fungus belonging to the genus Ramularia. In the present study, a fungus isolated from leaf lesions was grown under different growth conditions in order to study its mycelial growth and spore production, determining that the solid medium of Septoria tritici at 18 °C of incubation a...

Race Ug99 of Puccinia graminis f. sp. tritici, recognized for possessing virulence to Sr31, was first reported in Uganda in 1999 (Pretorius et al., 2000). Based on the North American stem rust nomenclature system of 16 differential lines (Roelfs and Martens, 1988; Roelfs et al., 1993), Ug99 is identified as race TTKS (Wanyera et al., 2006). Isolates with virulence similar to Ug99 were identifie...

Objective: Wheat leaf rust is one of the most widespread rust diseases caused by Puccinia triticina Eriks. De novo assembly of short sequence reads in order to understand the molecular phenomenon underlying wheat leaf rust interaction and to assemble differentially expressed genes, resistance genes and the genes encoding transcription factors in response to Puccinia infection in wheat was the m...

Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici, continues to cause severe damage worldwide. Durable resistance is necessary for sustainable control of the disease. High-temperature adult-plant (HTAP) resistance, which expresses when the weather becomes warm and plants grow older, has been demonstrated to be durable. We conducted numerous studies to understand the molecular ...

Glyphosate is a broad-spectrum herbicide used for the control of weeds in glyphosate-resistant crops. Glyphosate inhibits 5-enolpyruvyl shikimate 3-phosphate synthase, a key enzyme in the synthesis of aromatic amino acids in plants, fungi, and bacteria. Studies with glyphosate-resistant wheat have shown that glyphosate provided both preventive and curative activities against Puccinia striiformi...

Puccinia horiana Hennings, the causal agent of chrysanthemum white rust, is a worldwide quarantine organism and one of the most important fungal pathogens of Chrysanthemum × morifolium cultivars, which are used for cut flowers and as potted plants in commercial production regions of the world. It was previously reported to be controlled by Lecanicillium lecanii, Cladosporium sphaerospermum, C. ...

Sunflower rust, caused by Puccinia helianthi Schw., can result in significant yield losses in cultivated sunflower (Helianthus annuus L. var. macrocarpus Ckll.). HAR6 is a germplasm population resistant to most predominant rust races. The objectives of this study were to map the resistance factor present in HAR6 (R HAR6 ), and to provide and validate molecular tools for the identification of th...
