A REPORT ON THE RUST FUNGI OF HAMEDAN PROVINCE (IRAN)
Based on the morphological study of specimens of rust fungi collected during 2002-2003, a contribution is made to the rust fungus flora of Hamedan province: Uromyces inaequialtus var. ecbatanensis is described as new taxon. Melampsora allii-fragilis and Uromyces acantholimonis var. zagrosica are new reports for Iran. New observations on already known species were made: the aecia of Melampsora e...
متن کاملHigh level activation of vitamin B1 biosynthesis genes in haustoria of the rust fungus Uromyces fabae.
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...
متن کاملA putative amino acid transporter is specifically expressed in haustoria of the rust fungus Uromyces fabae.
A cDNA library constructed from haustoria of the rust fungus Uromyces fabae was screened for clones that are differentially expressed in haustoria. One family of cDNAs (in planta-induced gene 2 [PIG2] was isolated and found to encode a protein with high homologies to fungal amino acid transporters. A cDNA clone containing the complete coding region of PIG2 and the corresponding genomic clone we...
متن کاملDetection of Verticillium lecanii in Pustules of Bean Rust (Uromyces phaseoli) by Immunofluorescence
Verticillium lecanii has been found growing in pustu'les of the uredial stage of a number of rust fungi (GAMS 1971, SCHROEDER and HAssEBRAuK 1957, CASPER and MENDGEN 1979, SPENCER 1'980), and in some insects (HALL 1980). SCHROEDER and HASSEBRi\UK (1957) observed that this fungus is able to penetrate the urediospores of Puccinia striiformis. It remains to be shown, however, whether Verticillium ...
