Ordered processing of the polygenic transcripts from a mitochondrial transfer-RNA gene cluster in K. lactis.
No full textIn Saccharomyces cerevisiae, transcription of the mitochondrial genome starts at multiple initiation sites and is followed by the processing of multigenic transcripts at the 5' and 3' termini of tRNA sequences and in some intergenic regions. We have used a comparative approach to investigate the structure and function of the latter processing sites. We present here an analysis of the transcripts of a cluster of tRNA genes from the mitochondrial genome of Kluyveromyces lactis. The gene order of this cluster is the same as that of the cluster in S. cerevisiae but the sequence of the intergenic regions is different. A detailed analysis of transcripts has been performed using S1 mapping and primer extension techniques. The results can be summarized as follows: (1) transcription of the cluster very probably starts at initiation sites having the nonanucleotide sequence TTATAAGTA (which acts as a promoter in S. cerevisiae) and yields polygenic transcripts; (2) processing of these transcripts seems to occur through an ordered pathway of endonucleolytic events in which some tRNA sequences are preferentially excised and some endonucleolytic cuts occur more readily than others; (3) in two intergenic regions, strong signals indicate the existence of processing events. The sequences around these sites are similar in sequence and localization to S. cerevisiae intergenic processing sites, indicating a possible functional importance in maintaining a conserved order of tRNA genes in different species of yeasts

Analysis of transcripts of the major cluster of tRNA genes in the mitochondrial genome of S. cerevisiae
No full textThe transcripts of a 6Kbp region of the mitochondrial genome of S. cerevisiae, localized in the 21S rRNA-OXI1 span and including 12 tRNA genes (from tRNA(thr) to tRNA(ala)) and several G+C clusters, have been studied by analysis of in vitro capped primary transcripts and by fine mapping of the 5' ends of transcripts. The study was performed in the w.t. strain D273-10B and in several rho- mutants retaining different, partially overlapping portions of the studied region; the mutants accumulate incompletely-processed precursors of tRNAs due to the absence of the tRNA synthesis locus. Results show the presence in the region of four sites at which initiation occurs at a consensus nonanucleotide ATTATAAGTA (or a minor variant of the same); however different initiation sites are used in different strains, and several differences as compared to initiation in vitro can also be observed. Termini arising by processing are often localized at AATATAA or AATATATTTT sequences localized immediately adjacent to a G+C cluster or a tRNA sequence

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
