Effect of Barberry Eradication on Changes in Populations of Puccinia graminis in Minnesota

Plant Disease
Paul D PetersonT B Sutton

Abstract

Proportions of formae speciales of Puccinia graminis in collections of aeciospores from barberry were determined from cereal rust survey records from 1912 to 2002 in Minnesota. The frequency of P. graminis f. sp. avenae in aeciospore collections fluctuated between 0 and 10% from 1920 to 2002, even though oat was the dominant small grain crop in Minnesota until 1970. In early years, P. graminis f. sp. tritici was common, but the frequency of P. graminis f. sp. tritici in aeciospore collections declined to a low of 4% in the 1980s, whereas P. graminis f. sp. secalis increased to 96%. After 1990, the frequency of P. graminis f. sp. tritici increased and P. graminis f. sp. secalis declined in aecial collections, possibly indicating a changing proportion of P. graminis f. sp. secalis and tritici on wild grasses near barberry bushes. Diversity of races among uredinial collections of P. graminis f. sp. tritici from wheat in Minnesota declined sharply from 1912 to 1930 and remained low to 2002. Although the races of P. graminis f. sp. tritici most common in uredinial collections also were most common in the aecial collections in five of nine decades from 1912 to 1999 as well in the years 2000 to 2002, the diversity of races was greater...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
