Molecular cloning and analysis of abundant and stage-specific mRNAs from Puccinia
Floral" scent production by Puccinia
rust fungi that mimic flowers.
US maize geneticist Virginia Rhoades had shown in 1935 that the genetic locus Rp1, which gives resistance to maize rust, Puccinia
sorghi, was located near the tip of the short arm of chromosome 10.
In addition, the test can also be used to detect and/or verify advanced rust symptoms and spores, and does not cross react with several other rust infections caused by the genera Uromyces and Puccinia
, complementing visual inspections.
Wheat yellow rust is appearing since 2006-07 in parts of Punjab, Haryana, Jammu & Kashmir, Uttrakhand and Himachal Pradesh due to occurrence of Puccinia
Yellow rust or strip rust caused by puccinia
The stem rust fungus Puccinia
graminis has long plagued the world's wheat, barley, and other grain crops.
melanocephala, the fungus responsible, was previously endemic only in Asia and Africa.
This may lead to a much more complex system, such as that occurring in gene-for-gene interactions involving the cereal stem rust Puccinia
graminis, a serious pathogen of wheat crops.
The test can also be used to detect advanced rust symptoms and spores, and does not cross react with several other rust infections caused by the genera Uromyces and Puccinia
Stripe (yellow) rust of wheat, caused by Puccinia
Since 2005, plant scientists from research organizations around the world, including the Agricultural Research Service, have been sending their countries' top wheat cultivars and experimental lines to Njoro for testing against Ug99, Puccinia
