Russian knapweed (Rhaponticum repens) is a rangeland weed pest in the western United States. One candidate fungus for biological control of R. repens is Puccinia acroptili, which causes a rust disease. Understanding the life cycle of candidate rust fungi for weed biological control is an essential component in risk assessments and evaluations, and for P. acroptili such was unknown. For this reason greenhouse studies were undertaken to clarify the life cycle of P. acroptili under artificial…

Comparison of Puccinia acroptili from Eurasia and the USA
TLDR
DNA sequence analyses of the nuclear rDNA large subunit and internal tran- scribed spacer regions supported the notion that P. acroptili is a single species, but it also revealed that small levels of varia- tion may exist within the species.
Repeated formation of correlated species in Tranzschelia (Pucciniales)
TLDR
It is shown that a heteroecious macrocyclic strategy can be the starting point for deriving microcyclic autoecious species and suggested that this is a repeating process in the evolution of rust fungi.
Indian Pucciniales: taxonomic outline with important descriptive notes
  • A. Gautam
  • Biology, Environmental Science
    Mycosphere
  • 2021
TLDR
An overview and outline of rust fungi of India with important descriptive notes is provided and a phylogenetic analysis from a combined LSU and ITS dataset for 25 rust genera is presented to provide a better understanding of their phylogeny and evolution.
Unambiguous identification of fungi: where do we stand and how accurate and precise is fungal DNA barcoding?
TLDR
A conceptual framework for the identification of fungi is provided, encouraging the approach of integrative (polyphasic) taxonomy for species delimitation, i.e. the combination of genealogy, phenotype, and phenotype-based approaches to catalog the global diversity of fungi and establish initial species hypotheses.
Having sex, yes, but with whom? Inferences from fungi on the evolution of anisogamy and mating types
TLDR
It is argued that fungi represent highly suitable models to help resolve issues related to the evolution of distinct gamete classes, because the number of mating types vary from zero to thousands across taxa, anisogamy is present or not, and because there are frequent transitions between these conditions.

Self-fertility and other distinguishing characteristics of a new morphotype of Puccinia coronata pathogenic on smooth brome grass
TLDR
P. bromi does not require fertilization of pycnia to produce aecia on its alternate host, whereas fertilization is required in all other varieties or formae speciales of P. coronata with aecial hosts in the family Rhamnaceae and for which life cycles have been described.
Autoecious Puccinia species attacking Cardueae in North America
TLDR
The origins and relationships of the American Cirsium rusts are discussed in relation to those of the host plants and the evolution of very fine and close urediniospore echinulations, is described and exemplified.
Some Eurasian Puccinia species attacking Cardueae
Several lineages of Puccinia spp. attacking Cardueae are considered and species concepts are discussed, in an attempt to reach a better understanding of the evolution and relationships of these rusts…
Morphology, life cycle biology, and DNA sequence analysis of rust fungi on garlic and chives from california.
ABSTRACT In the late 1990s, commercial garlic fields in California (CA) were devastated by an outbreak of rust caused by Puccinia allii. We compared collections of the pathogen from garlic (Allium…
Fungi detected on Acroptilon repens (Russian knapweed) during surveys from 1981 to 1988

Puccinia acroptili on Russian Knapweed in Colorado, Montana, and Wyoming.
TLDR
To the authors' knowledge, this is the first record of P. acroptili in CO, MT, WY, and NM accessions, and these rust isolates have been identified as Puccinia acroPTili Syd.
Phylogeny of Rhaponticum (Asteraceae, Cardueae-Centaureinae) and related genera inferred from nuclear and chloroplast DNA sequence data: taxonomic and biogeographic implications.
TLDR
The new molecular evidence is consistent with the morphological and karyological data, and suggests particularly coherent biogeographic routes of migration and speciation processes for the genus Rhaponticum.
