Histones were extracted from purified nuclei isolated from four cereals,viz. barley (Hordeum vulgare), wheat(Triticum aestivum), Aegilops squarrosa and corn (Zea mais), and from tobacco (Nicotiana tabacum). Analysis of the histones on SDS gels showed complex electrophoretic patterns with one species
In wheat, adult plant resistance (APR) to leaf rust (Puccinia triticina), is effective in restricting pathogen growth and provides durable resistance against a wide range of virulent forms of P. triticina. Despite the importance, there is limited knowledge on the molecular basis of this type of
