This article analyzes weed differential characteristics and genomic specialty, proposes some specific weed candidates for genomic research. It elaborates on current application status of map-based approach, comparative genomics, RNAi, TILLING, T-DNA insertional mutagenesis strategies, genechip technology, etc. in genomic research,whlch can build overall understanding and dissect basic genetic and regulated mechanisms. It importantly expatiates the evolution of weed genomics and the expedition strategy of weed genomics research. It also indicates that developing weed genomics research can be helpful in establishing weed control technology systems, improving crop yield and quality, sequentially enhancing continuous productive forces in agriculture.
