Sliva数据库全称（SILVA ribosomal RNA database），是一个核糖体的rRNA基因序列数据库，用来检查和比对RNA序列, 既可以针对小亚基,SSU，16S/18S，也可以针对大亚基, LSU，23S/28S，包括了Bacteria, Archaea古生菌和Eukarya。

Large subunit ribosomal ribonucleic acid (LSU rRNA) is the largest of the two major RNA components of the ribosome. Associated with a number of ribosomal proteins, the LSU rRNA forms the large subunit of the ribosome.

2007年2月16日 · Here we evaluate the utility of the large subunit ribosomal rRNA (LSU) as a potential marker for species identification. The LSU is part of the rDNA gene complex which occurs in tandem repeats, arranged in ribosomal clusters in the nuclear genome [20].

2024年3月25日 · rDNA序列能转录出的前体RNA（pre-RNA，precursor RNA）包含LSU rRNA和SSU rRNA，以及两者之间的5s或5.8s rRNA。 在该前体RNA序列上不同rRNAs的内部并将rRNAs隔离开的转录区域，即为内转录间隔区。

2008年7月1日 · This study reports the complete LSU rRNA gene sequence in the causative unarmored dinoflagellate Cochlodinium polykrikoides, a member of the order Gymnodiniales, and evaluated the segmented domains and secondary structures when compared with its relatives. Putative LSU rRNA coding regions were recorded to be 3433 bp in length (49.0% GC content).

We performed PCR amplification of fungal rDNA using the primers LROR and LR3 (Vilgalys & Hester 1990) that target the D1-D2 region of the 28S rRNA gene, which is suitable for both taxonomic and...

This study presents the suitability of D1/D2 domain of large-subunit (LSU) ribosomal DNA (rDNA) for differentiation of Orpinomyces joyonii and Orpinomyces intercalaris based on PCR-restriction fragment length polymorphism (RFLP). A variation of G/T in O. intercalaris created an additional restriction site for AluI, which was used as an RFLP marker.

We show a good agreement between the two rRNA genes and confirm the main phylogenetic split between the freshwater and marine lineages. The informative superiority of the LSU data is shown by an increase of the resolution, nodal supports and tree indexes in …

To examine this, Demodex folliculorum, D. brevis, D. canis, and D. caprae were collected for DNA extraction, rDNA fragments amplification, sequencing, and analysis. The V2 and V4 regions of SSU rDNA; D5, D6, and D8 regions of LSU rDNA; and …

2007年2月16日 · In this presentation, the sequences of two species (mouse and Drosophila) are compared and a dot is placed in the diagram at each position where 10 consecutive nucleotides match. Conserved and...
