Tomato-Arabidopsis Synteny Map
The following links display the molecular marker linkage
maps of the tomato genome. When you click on any
chromosome, you will see two maps of each chromosome. The
first map (left side of image) is the high density
molecular marker map published by Tanksley et al. (1992).
On the right is a new map (Fulton et al, in prep) based
on COS markers.
Connecting the two maps (dashed lines) are common markers
on both maps. Because of the large number of markers on
each chromosome, it will not be possible to read the
individual marker names. To see an enlarged region of
each chromosome, click on the individual BINS which will
be highlighted at the right most part of the screen. This
will take you to an enlarged map of that section of the
chromosome in which the marker names will be readable. To
link to the sequence for any marker, click on the
corresponding marker name in the list to the right of the
map.
Both maps (high density RFLP map and COS marker map)
are based on F2 populations from the interspecific cross
L. esculentum x L. pennellii. Details of the high density
RLFP mapping population can be found in Tanksley et al.
(1992). The COS marker map is based on 80 F2 individuals.
Markers to the right of solid hash marks were ordered at
a LOD > 3; markers next to dashed hash marks are
ordered at a LOD > 2 but < 3; remaining markers are
given in the most likely interval (< LOD 3). Markers
next to a vertical bar cosegregate. The COS marker map
development is part of an ongoing project for determining
the syntenic relationship between the Arabidopsis and
tomato genomes. The map will be updated periodically as
new markers are added and new interactive features added
for making syntenic comparisons. Potato and eggplant
comparative maps will also be added soon.
