Génoplante recently contributed to the publication of the genetic –
physical map relationships of wheat microsatellites established using the
deletion bin system (Sourdille et al., 2004 ; Funct Integr Genomics
4 : 12-25). In order to make these data more easily available to the wheat
scientific community, we
deliver here the mapping data contained in the previous paper. We also provide
the mapping position of 862 new wheat SSR markers developed and mapped by
Génoplante. In addition, the SSR consensus map constructed by Somers et al.
(2004, Theor Appl Genet 109: 1105-1114) by fusing several genetic maps is
included to maximize the integration of genetic mapping informations from
different sources. The data
consist in seven Excel files (one for each homoeologous group) indicating the
name of the genetic map (Somers’ map (Consensus Somers), ITMI map (ITMI RFLP +
µsats) and the Courtot x Chinese Spring map (CtCS map)), the distances (in cM)
for each locus from the top of the chromosome (Position/top) and the distances
from the preceding anchor marker (markers in bold for ITMI and CtCS only,
Position/anchor). The deletion bins and chromosome arms are colour coded. Each
SSR locus assigned to a given deletion bin has the same colour code. Sizes of
deletion bins and locations of the centromeres were arbitrarily defined
according to the position of ITMI loci physically assigned. Common loci between
two or three maps are related with a line.
The gpw SSRs can now be used for academic research. If you want to use some
of them, please download and fill in carefully the
joint agreement (address,
names, list of the gpw SSRs, title and aims (5-10 lines) of the project), and
send three signed copies to Pierre Sourdille (address below). As soon as the
signed forms have been received, we will deliver an aliquot of the primer pairs
sufficient for 200 amplifications. Request for a maximum of 25 SSRs will be
considered. When more than 25 are needed, please send a specific request with
justification. Génoplante will consider these request on a case by case. Note that the users will be charged for
100 euros to cover the cost of primers, aliquot preparation and shipment.
