Fine Scale Genetic Mapping of the TT9 Locus of Arabidopsis thaliana

Numerous transparent testa (tt) or tannin deficient seed (tds) mutants have been isolated in the model plant Arabidopsis thaliana. These mutants are characterized by a reduction or lack of proanthocyanidins in the testa, resulting in pale brown or yellow seeds. Among the tt mutants, all the corresponding genes have been cloned except for tt9 and 13. As a first step towards determining the identity of the tt9 locus, fine scale genetic mapping was carried out using a mapping population resulting from a cross between tt9 plants in the Landsberg erecta (Ler) ecotype background with wild-type Columbia (Col) plants. Several simple sequence length polymorphism markers were developed, and a large population of plants was analyzed. Extensive analysis of this mapping population suggests the tt9 locus is found in a 140,000 base pair region on ch.. View More»
