Descubren composición genética de enfermedad que ataca los campos de avena en EE.UU. (en inglés)
A multi-institution team has identified the genetic mechanisms that enable the production of a deadly toxin called Victorin – the cause of Victoria blight of oats, a disease that wiped out oat crops in the US in the 1940s.
Victoria blight is caused by the fungus Cochliobolus victoriae, which produces the Victorin toxin, but until now no one has uncovered the genes and mechanisms involved.
“The oat varieties favoured by farmers in the 1940s were resistant to Crown Rust disease, but scientists later discovered this was the very trait that made those oat varieties susceptible to Victoria blight because the Victorin toxin was targeting that specific plant protein,” said co-senior author Gillian Turgeon, professor and chair of the Plant Pathology and Plant-Microbe Biology Section of the School of Integrative Plant Science, in Cornell’s College of Agriculture and Life Sciences (CALS). “Unearthing the molecules involved in this fungus-plant interaction is fundamental to our understanding of how plants respond to attack by diverse microbes.”
