Trends in genomics and molecular marker systems for the development of some underutilized crops

摘要: The term ‘underutilized’ is often used to characterize the range of plant species whose potential contribution food security, health, income generation, and environmental services has not yet been fully exploited. To harness unexploited resources, first step prevent them from extinction conserve in- and/or ex-situ. utilize as crops, plants must be collected, conserved, evaluated, then if necessary manipulated. In this context, significant international efforts have focused on impeding erosion genetic diversity. Thousands new accessions are introduced into germplasm institutes each year. Assessment their molecular diversity eliminate redundant genotypes. Marker systems only for genotyping reduce redundancy develop a core set, but also wide variety other purposes. use markers based single nucleotide polymorphisms, copy number variation, insertions/deletions, well by sequencing, becoming popular mapping analyses quantitative trait loci. This review discusses current marker genomic underutilized crops.
