European journal of plant pathology, 2018 The fungus Puccinia coronata Corda. is the causal agent of crown rust on oats (Avena sativa) and grasses and the disease is a major problem in oat production causing devastating yield losses. The population biology of P. coronata in oat fields and on the

The complex relationship between disease resistance and yield in crops
Plant Biotechnology Journal, Volume 22, Issue 9, Page 2612-2623, September 2024.Summary In plants, growth and defence are controlled by many molecular pathways that are antagonistic to one another. This results in a ‘growth‐defence trade‐off’, where plants temporarily reduce growth in response to pests or diseases. Due to this antagonism, genetic variants that improve resistance often reduce growth and vice versa.

Persistent virulence associations in sexual populations of Puccinia coronata [PDF]
Plant Pathology, 2006 From 1992 to 1999, 18 sets of aecial or uredinial isolates of Puccinia coronata were collected from two sites in Minnesota for analysis of virulence associations. In addition, one set of aecial isolates was collected in Ontario and one in New York. Also, aecial isolates and uredinial isolates

BMC Plant Biology, 2018 Background Protein kinases play a key role in plant cell homeostasis and the activation of defense mechanisms. Partial resistance to fungi in plants is interesting because of its durability. However, the variable number of minor loci associated with this

Germination of Aeciospores, Urediniospores, and Teliospores of Puccinia coronata
Botanical Gazette, 1921 1. Aeciospores from herbarium specimens of Rhamnus were not viable after a period of 167 days from date of collection. 2. Urediniospores from herbarium specimens of Avena sativa proved to be viable as long as 87 days after date of collection. 3. Unprotected urediniospores lost their viability within 22 days, with a minimum temperature, during this ...
