Not exact matches

This makes me happy: a research project has identified a gene that gives wheat plants resistance to one of the most deadly races of the wheat stem rust pathogen, Ug99.

It is estimated that globally 5.47 million tonnes of wheat are lost to the stripe rust pathogen each year, equivalent to US$ 979 million.

The concept of ETI was developed to describe defense against pathogens that enter into plant cells (e.g. wheat rusts and mildews, potato late blight pathogens) and fits their defense mechanisms well.

«Isolation of Stb6 is a major breakthrough that will allow deeper understanding of disease resistance mechanisms operating in wheat against this important pathogen,» says Kanyuka.

First, they chemically mutagenized the resistant accession of wheat to identify plants that become susceptible to the stem rust pathogen.

Eduard Akhunov, associate professor of plant pathology at Kansas State University, and his colleague, Jorge Dubcovsky from the University of California - Davis, led a research project that identified a gene that gives wheat plants resistance to one of the most deadly races of the wheat stem rust pathogen — called Ug99 — that was first discovered in Uganda in 1999.

The joint US and Australian research team has now generated the first haplotype - resolved genome sequences for the rust fungi causing oat crown rust and wheat stripe rust diseases, two of the most destructive pathogens in oat and wheat, respectively.

Their next step is to test the isolates they've captured on plants such as tomatoes, potatoes, wheat, oat and rye to see if they have qualities of beneficial bacteria or those of pathogens.

Chemical controls are costly and potentially harmful to human and environmental health, so protecting crops like wheat with inherent resistance is the smart alternative, but resistance must be genetically complex, combining several genes, to withstand new mutations of the pathogen over time.

We consider the unique combination of having alive bio-assays of pathogen «races» in house, and the possibility to investigate the same material by advanced molecular tools, as a major advance for understanding the evolutionary processes of the wheat rusts.

Areas of focus include three major groups of human pathogens (Candida albicans, Cryptococcus neoformans, and the dimorphic fungi), obligate pathogens of diverse hosts (Microsporidia and Pneumocystis), and the wheat rust fungi (Puccinia sp) that cause current agricultural epidemics.

There are two general types of resistance genes found in wheat: Race - specific genes confer a high - level of resistance to specific strains of leaf rust but can be easily overcome by genetic mutation in pathogen populations, while slow rusting (APR) resistance provides partial resistance to a broad spectrum of races, but is typically effective only at the adult stage of plant growth.

My hunch is that these pathogens are somewhat unique, due to long - term feeding on high amounts of fructose, wheat, and other neolithic foods.
