Integration of AFLPs, SSRs and SNPs markers into a new genetic map of industrial chicory (Cichorium intybus L. var. sativum).

摘要

A chicory genetic map of 1208 cM has been created using 247 F₂ plants and 237 markers (170 AFLP, 28 SSR, 27 EST-SNP and 12 EST-SSR). This map covers 84% of the chicory genome. The chicory-genic-markers-associated sequences were used to find potential orthologs in mapped lettuce ESTs from the Compositae Genome Project Database. Twenty-seven putative orthologous pairs were retained, pinpointing seven putative blocks of synteny that covered 11% of the chicory genome and 13% of the lettuce genome, opening new perspectives for the analysis of these two species.
