Macro-scale risk assessment and host response to orange rust (Puccinia kuehnii) in sugarcane across tropical zones under current and future climate scenarios

Frontiers in Agronomy
Puccinia kuehnii, the causal agent of orange rust, is an obligate biotrophic fungus and an emerging phytosanitary threat to sugarcane production. Although widely distributed in Colombia, its current impact and future risk under climate change remain ...

First Report of Orange Rust of Sugarcane Caused by Puccinia kuehnii in Costa Rica and Nicaragua

Plant Disease, 2009
Symptoms and signs of orange rust on sugarcane (a complex hybrid of Saccharum L. species) were observed from July 2007 on cv. SP 71-5574 in Costa Rica at the Coopeagri Sugar Mill located in Pérez Zeledón, San José and on multiple cultivars (CP 72-2086, Pindar, Q 132, Q 138, SP 71-5574, and SP 79-2233) at the Providencia Sugar Mill near Muelle, San ...

First Report of Orange Rust of Sugarcane Caused by Puccinia kuehnii in Guyana

Plant Disease, 2018
In September 2012, orange uredinial lesions (0.3 mm to 1.2 mm in length x 0.1 mm to 0.3 mm in width; mean of 0.6 mm ± 0.16 mm in length x 0.2 mm ± 0.01 mm in width) surrounded by dark, reddish-brown necrotic tissue and running parallel to the leaf venation were observed on leaves of a major commercial sugarcane (Saccharum spp. L.

Development of a single uredinium inoculation method for Puccinia kuehnii, the causal agent of sugarcane orange rust [PDF]

Summa Phytopathologica, 2018
ABSTRACT The use of resistant varieties is the ideal method to control rusts. Nevertheless, knowing the pathogen’s diversity is fundamental to the success of this measure. Diversity can be analyzed phenotypically and/or genotypically. For phenotypic diversity, the reaction of genotypes is assessed by means of inoculations of the pathogen generally ...

First Report of Orange Rust of Sugarcane Caused by Puccinia kuehnii in Mexico, El Salvador, and Panama

Plant Disease, 2009
Symptoms of sugarcane orange rust were observed on July 17, 2008 on sugarcane cvs. Mex 57-1285, Mex 61-230, and Co 301 (a clone received in Mexico in 1953) at the Centro de Investigación y Desarrollo de la Caña de Azúcar en Tuxtla Chico, Chiapas, Mexico. In El Salvador, from August 2008 through January 2009, rust symptoms were observed on cv.

First Report of Puccinia kuehnii, Causal Agent of Orange Rust of Sugarcane, in the United States and Western Hemisphere

Plant Disease, 2008
In June 2007, approximately 8 km east of Belle Glade, FL, a rust disease was observed on a sugarcane (a complex hybrid of Saccharum L. species) cultivar (CP 80-1743) considered resistant to brown rust caused by Puccinia melanocephala Syd. & P. Syd.

Genome sequencing of the sugarcane orange rust pathogen Puccinia kuehnii

, 2019
Puccinia kuehnii, the causal agent of orange rust, is a fungal pathogen that causes damaging losses to the sugarcane crop in Florida since 2007. During plant infection, rust fungi deliver effector proteins into host tissues using a specialized feeding structure called a haustorium, to manipulate plant functions and promote parasitic growth ...
