rhizoctonia zeae causes root rot and sheath blight on corn (zea mays) and several other gramineous plants. in order to determine the genetic diversity of the r. zeae population in mazandaran and golestan provinces, samples were collected from cultivatd soils of both provinces in 2011 and 2012.the identity of isolates as r. zeae were verified by amplification and sequencing of the 18s and 28s rd...

Chromosome segregation is triggered by the cleavage of cohesins by separase. Here we show that in budding yeast separation of the ribosomal DNA (rDNA) and telomeres also requires Cdc14, a protein phosphatase known for its role in mitotic exit. Cdc14 shares this role with the FEAR network, which activates Cdc14 during early anaphase, but not the mitotic exit network, which promotes Cdc14 activit...

Abstract A small slug found in the tropical greenhouse of Science Museum (MUSE) Trento (Italy) turned out to be a species little-known systellommatophoran family Rathouisiidae. We undertook detailed comparative anatomical and molecular studies using specimens MUSE slug, Rathouisia sinensis, sequences other deposited GenBank conduct systematic phylogenetic assessment. Analysis genitalia R. sinen...

some fungal species were isolated from scab or scab-like symptoms on leaves of various plant hosts in iran. some of them isolated from apple and pear leaves were investigated in the present study. the isolates were identified based on the morphological and cultural characteristics. on the other hand, for molecular identification and phylogenetic analyses were carried out based on the sequence o...

In this study, Rhizopogon pumilionum (Ade) Bataille is recorded from Turkey for the first time. The new record described and illustrated. New was proved by utilizing its rDNA ITS data. Also, phylogenetic position of R. detected in tree constructed using sequences ITS.
