Nomenclature

There are seven different types of "Clone" objects in WormBase:


Type Nomenclature
Cosmid A*, B*, C*, D*, F*,J*,K*,M*,R*,T*,W*,Z*
Fosmid H* WRM*
YAC Y*
cDNA yk*, EC*, EB*, OST*, CK*, EF*, CEE*, CEM*, CES*, CB*, CN*, cm*
Plasmid: PCR clones V*,EGAP*
Other telo clones, 1 BAC, plasmid

Most Cosmids, Fosmids, YACs can be requested from Sanger via the form at the top of the page,

cDNA (yk*) from Dr. Yuji Kohara.

The EGAP* plasmids can be obtained from........

WRM Vancouver_fosmid

The V* plasmids are no longer available.

The EC* ESTs were distributesd by Exelixis but are no longer available.

YAC clone Information

Specific YAC information can be found in these publications:

Nature. 1988 Sep 8;335(6186):184-6. Genome linking with yeast artificial chromosomes. Coulson A, Waterston R, Kiff J, Sulston J, Kohara Y.

science 1987 May 15;236(806-812) Cloning of large segments of exogenous DNA into yeast by means of artificial chromosome vectors. DT Burke, GF Carle, and MV Olson

Note When ordering YAC clones.
Suffixes appended to YAC names (e.g. Y73B3A, Y73B3B) indicate sequenced segments of the YAC that have been used to bridge gaps between finished Cosmids

They do not exist as subclones so you will be sent the whole YAC.


Clone ends within wormbase

The set of clone ends is dumped as part of the gff files:

http://www.sanger.ac.uk/Projects/C_elegans/WORMBASE/GFF_files.shtml

This is the source for the extents displayed in WormBase.

The caveat with this is that the 'true' end is not marked up for all clones. The early cosmids do not have such annotations because nobody thought about marking them up. Later cosmids do have clone left and right ends as this became part of the standard procedure. Finally, many of the YACs do not have clone ends because the segment submitted to GenBank/EMBL is much smaller than the full clone, and hence the true ends lie within sequences already finished at that stage of the sequencing (i.e. we never went back to update clone ends in sequence already finished).
