New functional molecular markers for plants in the functional genomics era
植物功能基因组研究中出现的新型分子标记

With the development of functional genomics,expressed sequence tags(ESTs)has become an important resource of PCR-based molecular markers for plants.The advancement in functional molecular markers for plants in the functional genomics era,including EST-SSR,CAPS,SNP,SRAP and TRAP were reviewed.Compared with conventional markers,the EST-derived markers are a novel type of molecular tool with remarkable advantages,such as being easily to develop,more informative,and highly transferable,especially for preferential targeting ORFs.Applications of the new functional molecular markers in plants genetics and breeding are summarized,such as construction of genetic linkage maps,important trait gene tagging location,comparative mapping,genetic diversity,cultivars identification and marker-assisted selection breeding.
