متن کاملAn interspecific barberry hybrid enables genetic dissection of non-host resistance to the stem rust pathogen Puccinia graminis.
Stem rust, caused by Puccinia graminis (Pg), remains a devastating disease of wheat; and the emergence of new Pg races virulent on deployed resistance genes fuels the ongoing search for sources of durable resistance. Despite its intrinsic durability, non-host resistance (NHR) is largely unexplored as a protection strategy against Pg, partly due to the inherent challenge of developing a genetica...
متن کاملRoot Rots of Wheat, Oats, Rye, Barley
The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions. To the many types of root rots in cereal crops many names ha...
متن کاملGenetic Variation and Virulence on Lr26 in Puccinia triticina.
ABSTRACT The genetic relationships between isolates of Puccinia triticina virulent on wheat with the Lr26 resistance gene were studied. The diversity within and between isolates of P. triticina from Israel, Europe, and the United States was determined by virulence on near-isogenic Thatcher lines and by random amplified polymorphic DNA. According to the molecular markers, isolates that were viru...
متن کاملDNA Comparisons among Barley, Oats, Rye, and Wheat.
F all groups of plants, none can match the cereal grains in importance to O m a n . Their origins in cultivation have been traced back some 9,000 years to the beginnings of agriculture ( HELBAEK 1960). Extensive cytogenetic studies have been undertaken with this group of plants from which their taxonomic and supposed evolutionary relationships may be deduced (BELL 1965; RILEY 1965). Some of the...
