TOWARD A SATURATED LINKAGE MAP IN TOMATO BASED ON ISOZYMES AND RANDOM cDNA SEQUENCES

Bernatzky, Robert, Tanksley, Steven D·1986·Genetics

Abstract

A linkage map in tomato has been developed based on isozyme and random cDNA clones derived from mRNA. Interspecific backcross and F2 populations of Lycopersicon esculentum and L. pennellii were employed in the linkage analysis. Allelic differences in cDNA markers were based on restriction fragment length polymorphisms detected through Southern analysis. A total of 57 unique cDNA clones have been analyzed. The majority of cDNA markers correspond to single loci and are dispersed throughtout the genome. Of those clones that hybridize to two or more loci, most show genetic independence (ie., they are unlinked). The combination of isozyme, cDNA and previously mapped DNA markers total 112 loci. It is estimated that approximately 92% of the genome can be monitored during segregation with these markers. Molecular maps, such as the one being constructed in tomato, may allow genetic and breeding experiments that previously were not possible.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
