Of the 153 SSR markers identified to reside closely with these genes, 22 (14%%) exhibited clear polymorphism between the two parents.
These microsatellites represent a major fraction of co-dominant polymorphic markers identified to date in catfish, and should be a valuable resource for genetic mapping to increase linkage map resolution, and for integration of genetic linkage and physical maps.
To initially test the involvement with grain yield (GY, AII genes found to respond in two contrasting water regimes (listed in Additional file 7: Tables S5) were aligned in-silico with genetic markers identified to have significant effects on GY under drought stress (Venuprasad et al. 2009).
A number of the immune markers identified to be differentially expressed after infection with S. epidermidis appeared regulated in the same way after M. marinum yolk infection.
This strategy limits the exploration of PC aberrancies to variations of the expression of CD19 and CD45, yet, among markers identified to be more specifically associated to malignant PCs, CD56 and CD28 appear to be of great value.
The effects of individual markers are small, so that even under the multiplicative polygenic model the combined effect of those markers identified to date explains less than 4% of the polygenic variance [ 14].
