Differential impact of crown rust (Puccinia coronata) infection on photosynthesis and volatile emissions in the primary host Avena sativa and the alternate host Rhamnus frangula.

Journal of Experimental Botany, 2023
Rust infection results in decreases in photosynthesis and stress volatile emissions, but how these changes vary among host species has not been studied. We demonstrated the impact of the obligate biotrophic fungus, Puccinia coronata f. sp.

Puccinia coronata var. coronata, a crown rust pathogen of two highly invasive species, is detected across the Midwest and Northeastern United States.

Plant Disease, 2022
Puccinia coronata var. coronata (Pcc) causes crown rust disease of glossy buckthorn (Frangula alnus) and reed canarygrass (Phalaris arundinacea), two highly invasive plant species in North America.

Oat crown rust disease severity estimated at many time points using multispectral aerial photos.

Phytopathology, 2021
All plant breeding programs are dependent on plant phenotypic and genotypic data, but the development of phenotyping technology has been slow relative to that of genotyping. Crown rust (Puccinia coronata f. sp.

Identification of diagnostic kompetitive allele‐specific PCR markers for selection of crown rust resistance in oats

Crop science
Crown rust disease, caused by Puccinia coronata f. sp. avenae, poses a significant threat to global oat (Avena sativa L.) production. Molecular markers are essential to assist in the integration of multiple resistance genes into a single oat cultivar to ...

Crown rust resistance in ryegrasses

1999
Reciprocal crosses between Lolium multiflorum plants and between L. multiflorum and L. perenne plants, which were either resistant or susceptible to crown rust were performed and the mode of inheritance of the resistance was analysed. In the crosses in which the resistant plants Axis-1 or Axis-2 were involved, a maternal type of inheritance was ...

AN ASSOCIATION OF STEM RUST AND CROWN RUST RESISTANCE IN JOSTRAIN OATS

Canadian Journal of Genetics and Cytology, 1968
Rodney backcross lines carrying single genes for stem rust resistance were tested with 10 cultures of crown rust. Lines possessing genes Pg-1, Pg-2, Pg-4 and pg-8 were susceptible to all cultures of crown rust used, whereas the line carrying Pg-3 was highly resistant to several of these cultures. Studies of 51 Victory2 x Jostrain F2 backcross families

Breeding perennial ryegrass with better crown rust resistance

Plant Breeding, 1996
AbstractImproving rust resistance is one of the main goals in our breeding programme with perennial ryegrasses. We have studied the behaviour of our breeding material over several years in several locations under natural and artificial infection conditions.

Dissecting cellular resistance responses in oat reveals novel sources of pre/post-haustorial defence against crown rust at seedling and adult stages.

Plant Disease
Oat production in the Mediterranean region face important yield and quality challenges, with crown rust (caused by Puccinia coronata f. sp. avenae) being one of the most important critical biotic constraints.

Induction to Resistance to Crown Rust in Oat

Journal of Phytopathology, 1996
AbstractInduction of resistance to crown rust, caused by Puccinia coronata Cda. var, avenae Frazer et Led., occurred in seedlings of three genetic lines of oats (Avena sativa L.) inoculated sequentially with one of three inducer‐challenger combinations of the pathogen.

SEEDLING REACTIONS OF WHEAT VARIETIES TO STEM RUST AND LEAF RUST AND OF OAT VARIETIES TO STEM RUST AND CROWN RUST

Canadian Journal of Research, 1940
A study of the rust reactions of wheat varieties to 20 physiologic races of stem rust has shown that several varieties of the vulgare type, namely, McMurachy, Eureka, and several strains from Kenya, East Africa, are immune in the seedling stage at ordinary greenhouse temperatures (55° F. to 80° F. daily).
