Introduction Rust diseases of wheat are among the oldest plant diseases known to humans. Early literature on wheat cultivation mentions these devastating diseases and their ability to destroy entire wheat crops. Since rust discovery, numerous studies have been conducted on the life cycles of rust pathogens and their management. The information gained from these studies has enabled us to develop...

Fusarium oxysporum f. sp. lini is a hemibiotrophic fungus that causes wilt in flax. Along with rust, fusarium wilt has become an important factor in flax production worldwide. Resistant flax cultivars have been used to manage the disease, but the resistance varies, depending on the interactions between specific cultivars and isolates of the pathogen. This interaction has a strong molecular basi...

Loblolly pines (Pinus taeda L.) thut were 8 to 17 yr old tolerated one to three fus[form rust (Cronartium quercuum [Berk.]Miyabe exShiraij sp. fusiforme) galls in theirstems. Families withfourormore galls in their stems lost 2.5% or more ofthe trees by age 17. In living trees with less thanf<jurstem galls, diameter growth was comparable to that of trees with no galls. Tolerance was indicated by...

Probabilities of death of young slashpine infected byfusiform rustpathogen varied with timing and severity of infection. Trees in nine slashpineplantations varying widely in site quality and initial number oftreesperacre hadsimilarprobabilities ofdeathfrom rust. About 90% oftrees with stem infections in thejirst three growing seasons died by age 15 if the gall spanned more than 50% of the circu...

BMJ Case Reports Published online: 2 January 2013 doi:10.1136/bcr-2012007716 DESCRIPTION The accidental or suicidal ingestion of corrosives induces severe oesophagogastric damage that range from superficial erosions to perforation. The extension of the damage depends on several factors like the form of the substance (liquid, solid or gel), the pH of the substance (acid...

Sir: Stem rust (Puccinia graminis f. sp. tritici) is a serious wheat disease causing decrease of wheat production in many areas of the world1) and has been partially controlled so far by the use of resistant races2), eradication of the alternate host, i.e. barberry3), or by synthetic fungicides4~7) We undertook the screening of new antibiotics active against wheat stem rust fungus using an inhi...

Development and characterization of expressed sequence tag-derived microsatellite markers for the wheat stem rust fungus Puccinia graminis f. sp. tritici. Phytopathology 99:282-289. Puccinia graminis f. sp. tritici is the causal agent of stem rust disease in wheat. The rust fungus has caused devastating disease epidemics ...

Acacia koa (koa), among the most prominent overstory species of native Hawaiian forests, is affected by a number of diseases, including those caused by rust fungi, wood-rotting fungi, root-infecting fungi, and diseases categorized as seedling blights, foliar infections, and vascular wilts. A number of fungi occurring saprophytically on koa substrates are also known. Symptoms of other apparent d...
