to evaluate fertility status and mating type distribution of cryphonectria parasitica, causal agent of chestnut blight in guilan province, four sites in two main growing regions of: shaft (visrud, taleghan and babarekab), and rezvanshahr (doran) were investigated. during the study, fifty four isolates of c. parasitica were examined. c. parasitica isolates were crossed with each of the two matin...

fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....

leptospirosis is an acute infectious, systemic and septisemic disease which had recent outbreaks in some parts of iran especially in north provinces. rapid detection is a critical step for treatment and control of this disease. in this research a pcr based method was evaluated for detection of iranian local endemic serovars. all reported endemic serovars of leptospira including leptospira gripp...

background: toxoplasma gondii can infect all warm-blooded animals. modified agglutination test (mat) and elisa are widely used for the detection of t. gondii antibodies. however, there is little information on their acceptability for detecting antibodies in companion animals. methods: this study compared elisa and mat for their ability to detect t. gondii infection in natu­rally infected dogs a...

Aimed at investigating the recovery of a specific mutant allele of the mating type locus (MAT) by switching a defective MAT allele, these experiments provide information bearing on several models proposed for MAT interconversion in bakers yeast, Saccharomyces cerevisiae. Hybrids between heterothallic (ho) cells carrying a mutant MAT a allele, designated mata-2, and MAT alpha ho strains show a h...

Bark beetles (Coleoptera: Scolytidae) are among the most important killers of trees in the family Pinaceae, especially on Pinus, Picea and Larix (15). Bark beetles are intimately associated with a variety of fungi, most notably, members of the genus Ophiostoma and their associated anamorphic species of Leptographium (5–7). Although species of Ceratocystis sensu stricto are generally associated ...
