فلور قارچهای راسته های زنگ ها (uredinales) ، سیاهک ها (ustilaginales) و سفیدک های پودری(erysiphales) درمنطقه حفاظت شده جاجرود در شرق استان تهران که در بردارنده دو پارک ملی سرخه حصار و خجیر می باشد بررسی گردید . بر این اساس 26 گونه از راسته زنگ ها متعلق به جنس های melampsora, uromyces, puccinia, phragmidium ، 14 گونه از رسته سفیدک های پودری متعلق به جنس blumeria, podosphaera, leveillula, erysiph...

ABSTRACT DNA fingerprinting has been used extensively to characterize populations of Mycosphaerella graminicola, the Septoria tritici blotch pathogen of wheat. The highly polymorphic DNA fingerprints of Mycosphaerella graminicola were assumed to reflect the action of transposable elements. However, there was no direct evidence to support that conclusion. To test the transposable element hypothe...

In the rust fungus Uromyces fabae, the transition from the early stages of host plant invasion toward parasitic growth is accompanied by the activation of many genes (PIGs = in planta induced genes). Two of them, PIG1 (= THI1) and PIG4 (= THI2), were found to be highly transcribed in haustoria, and are homologous to genes involved in thiamine (vitamin B1) biosynthesis in yeast. Their functional...

Rust fungi are plant parasites which colonise host tissue with an intercellular mycelium that forms haustoria within living plant cells. To identify genes expressed during biotrophic growth, EST sequencing was performed with a haustorium-specific cDNA library from Uromyces fabae. One thousand seventeen ESTs were generated, which assembled into 530 contigs. Several of the most frequently represe...
