Effect of Chitosan on the Expression Pattern of Some Pathogenecity Related Genes in Wheat Infected with Powdery Mildew

Powdery mildew, caused by Blumeria graminis f.sp tritici, known as a destructive disease of wheat worldwide that led to severe crop loss, annually. As chemical control is expensive and not ecologically safe, application of non-toxic chemicals to induce defense mechanism in plant host is desirable. In present study, induction of host resistance using chitosan on the expression of pathogenicity r...

Bacillus sp. BS061 Suppresses Gray Mold and Powdery Mildew through the Secretion of Different Bioactive Substances

A Bacillus sp. BS061 significantly reduced disease incidence of gray mold and powdery mildew. To identify the active principle, the culture filtrate was partitioned between butanol and water. The antifungal activity against B. cinerea was evident in the butanol-soluble portion, and active substances were identified as cyclic lipopeptides, iturin A series, by nuclear magnetic resonance spectrome...

Fungi Associated With the Powdery Mildew of Buxus Trees in Gorgan Landscape

In this research,for taxonomic studies and identification of the fungi associated with the powdery mildew(Oidium euonymi- japonici) of Buxus trees (Euonymus japonica), the infected leaves were collected during autumn and winter 2012-2013 in Gorgan (Golestan province -Iran). The samples after washing and surface sterilizing, were cultured on PDA medium(with boxwood extract).Then based on availab...
