Electron microscopy of teliospore formation in Puccinia coronata avenae
Physiological Plant Pathology, 1977Abstract Teliospores of Puccinia coronata avenae developed as sympodioconidia, and up to the stage of primary spore cell formation their ontogeny was similar to that of urediospores. After the primary teliospore cells were formed they elongated and a heavy cap of wall material formed at the terminal end (the crown) of the cell.

Selection against unnecessary virulence in Puccinia coronata
2000A population of Puccinia coronata derived from a bulk collection of urediniospores from oat growing near a hedge of the aecial host, Rhamnus cathartica, was grown for 10 uredinial generations on seedlings of a susceptible oat cultivar in the greenhouse.

Comparisons of traits of aggressiveness in sexual and asexual populations of Puccinia coronata
2018It is generally considered advantageous for populations to periodically recombine their genes in order to increase both the genetic variability and the rate of response to changing environments. Theoretical and experimental evidence, however, has not clearly substantiated this view and actually has led to some confusion about the role of gene ...

Zum Wirstpflanzenkreis des Kronenrostes (Puccinia coronata Corda var. coronata).
Česká Mykologie, 1978Analysis of the host plant range of the important parasite of Festuca pratensis Huds. — the crown rust Puccinia coronata Corda var. coronata — showed that this is indeed the graminicolous form of this rust species. Positive infection was observed in 24 grass species out of 174 tested from the Poaceae family.
