Fragments of the internal transcribed spacer 1 of pre-rRNA accumulate in Saccharomyces cerevisiae lacking 5'----3' exoribonuclease 1.
The portion of the internal transcribed spacer 1 found on 20S pre-rRNA accumulates in Saccharomyces cerevisiae lacking 5'----3' exoribonuclease 1, showing that an endonucleolytic cleavage at the 3' terminus of 18S rRNA is involved in the 20S pre-rRNA to 18S mature rRNA conversion. Smaller fragments of the spacer sequence are also found. The exoribonuclease may be involved as a cytoplasmic RNase...
متن کاملSeparate structural elements within internal transcribed spacer 1 of Saccharomyces cerevisiae precursor ribosomal RNA direct the formation of 17S and 26S rRNA.
Structural features of Internal Transcribed Spacer 1 (ITS1) that direct its removal from Saccharomyces cerevisiae pre-rRNA during processing were identified by an initial phylogenetic approach followed by in vivo mutational analysis of specific structural elements. We found that S. cerevisiae ITS1 can functionally be replaced by the corresponding regions from the yeasts Torulaspora delbrueckii,...
متن کاملNucleotide sequence analysis of the Second Internal Transcribed Spacer (ITS2) in Hyalomma anatolicum anatolicum in Iran
Ticks are important acarina that infest animals. They are obligatory blood sucker arthropods which economically impact cattle industry by reducing weight gain and production. Moreover, they are important vectors of viral, bacterial, rickettsial and parasitic pathogens infecting humans and animals. In view of the importance of Hyalomma anatolicum anatolicum in pathogen transmission, including Th...
متن کاملStudy of the Molecular Diversity of Internal Transcribed Spacer Region (ITS1.4) in Some Lettuce Genotypes
Lettuce is belong to the Cichorium family with leaf consumption, Annual cold weather plants and rich in minerals, vitamins and nutrients. The aim of the present study was to evaluate the genetic diversity of 15 varieties and lettuce populations using the ITS area. Sequence quality was evaluated using Chromas 2.1.1 software, aligned by MegAlign 5 software and then similarity matrix and dendrogra...
متن کاملVariability of the 16S-23S rRNA gene internal transcribed spacer in Pseudomonas avellanae strains.
The 16S-23S rRNA gene internal transcribed spacer region (ITS1) from 34 strains of Pseudomonas avellanae and some strains of Pseudomonas syringae pathovars was amplified and assessed by restriction fragment length polymorphism (RFLP) using 10 restriction enzymes. In addition, the ITS1 region of four representative P. avellanae strains was sequenced and compared by the neighbour-joining algorith...
