wikify date March 2011 In 2008, by pyrosequencing of cDNA from the brains of several parrots suffering from Proventricular Dilatation Disease PDD , Honkavouri et al. identified the presence of a novel Borna virus ref Honkavouri KS, Shivaprasad HL, Williams BL, Quan P L, Hornig M, Street C, Palacios G, Hutchison SK, Franca M, Egholm M, Briese T, and Lipkin WI. Novel bornavirus in psittacine birds with proventricular dilatation disease. 2008 . Emerging Inf Dis. 14 1883 1886. ref . Using real time PCR, these investigators confirmed the presence of this virus in the brains and proventriculus of three cases of PDD but not in four unaffected birds. At approximately the same time, Kistler and her colleagues used a microarray approach to identify a Borna virus hybridization signature in three out of five PDD cases but not in eight control parrots ref Kistler AL, Gancz A, Clubb S, Skewes Cox P, Fischer K, Sorber K, Chiu CY, Lublin A, Mechani S, Farnoushi Y, Greninger A, Wen, CC, Karlene SB, Ganem D and DeRisi JL 2008 . Recovery of divergent avian bornaviruses from cases of proventricular dilatation disease Identification of a candidate etiologic agent. Virology Journal. 5 88. ref . Using high throughput pyrosequencing in combination with conventional PCR cloning and sequencing, these investigators recovered the complete viral genome sequence and named this virus avian Borna virus ABV . At least seven distinct ABV genotypes have now been identified and sequenced. In general these ABV genotypes show only about 65 sequence identity with mammalian Borna disease Virus BDV . Nevertheless, the overall structure of the bornaviral genome is well conserved. Thus the number and order of genes is unchanged as is the structure of transcription initiation and termination sites. Rinder and her colleagues have shown that ABV apparently lacks a 22 nucleotide fragment that serves a regulatory function for the genes coding for viral proteins X and P ref Rinder, M., Ackermann, A., Kempf, H., Kaspers ... more details

SuperSAGE is the most advanced derivate of the serial analysis of gene expression technology SAGE for the analysis of expressed genes in eukaryotic organisms gene expression profiling . Like in SAGE, a specific tag from each Transcription genetics transcribed gene is recovered. By DNA sequencing sequencing and counting as many tags as possible, the transcription profile, stating what gene is described and how often, becomes apparent. SuperSAGE uses the type III endonuclease EcoP15I of P1 phage phage P1 , to cut 26 bp long sequence tags from each transcript s cDNA , expanding the tag size by at least 6 bp as compared to the predecessor techniques SAGE and LongSAGE. ref name Matsumura2003 cite pmid 14676315 ref The longer tag size allows for a more precise allocation of the tag to the corresponding transcript, because each additional base increases the precision of the annotation considerably. Like in the original serial analysis of gene expression SAGE protocol, so called ditags are formed, using Blunt ends blunt ended tags. However, SuperSAGE avoids the bias observed during the less random LongSAGE 20 bp ditag ligation. By direct sequencing with modern high throughput sequencing techniques next generation sequencing , i.e. pyrosequencing , hundred thousands or millions of tags can be analyzed simultaneously, producing very precise and quantitative Gene expression profiling gene expression profiles . Therefore, tag based gene expression profiling also called digital gene expression profiling DGE can today provide most accurate transcription profiles that overcome the limitations of microarrays. ref cite doi 10.1038 nmeth0708 585 ref The 26 bp tags have a number of advantages over the smaller tags Most notably due to the exact annotation of SuperSAGE tags at least 10,000 times more accurate than LongSAGE tags , a substantially increased number of transcripts can be differentiated. Many different Protein isoform transcript isoforms representing Alternative splicing alt ... more details

Multiple issues context February 2009 expert Genetics date February 2009 refimprove January 2010 SOLiD Sequencing by Oligonucleotide Ligation and Detection is a next generation sequencing technology developed by Life Technologies and has been commercially available since 2008. These next generation technologies generate hundreds of millions to billions of small sequence reads at one time. Well known examples of such DNA sequencing methods include 454 pyrosequencing introduced in 2005, generating millions of 200 400bp reads in 2009 , the Solexa system introduced in 2006, generating hundreds of millions of 50 100bp reads in 2009 and the SOLiD system introduced in 2007, generating billions of 50bp reads in 2009 . These methods have reduced the cost from 0.01 base in 2004 to nearly 0.0001 base in 2006 and increased the sequencing capacity from 1,000,000 bases machine day in 2004 to more than 5,000,000,000 bases machine day in 2009.
