Özet
Genomics, emerged in the 1990s as a revolutionary approach, studies the structure and function of all the genes in an organism. Genome size studies, physical mapping, and genetic mapping applications were developed for characterizing and comparing genomes prior to the advent of high-throughput next-generation sequencing (NGS) technologies. Arrival of NGS techniques have redirected attention away from these older methods and made it possible to sequence, assemble, and analyze the genomes of many plant species. The release of the first plant genome sequence belonging to Arabidopsis, in 2000, brought new insights and perspectives into our understanding of plant genomics. Rapid progress has since been made and not only model organisms but also a variety of species of ecological, agricultural, or economical importance has been sequenced generating a huge amount of data. These data are publicly available through web portals, e.g., the Ensembl Plants portal (http://plants. ensembl.org/index.html) and the NCBI genome portal (http://www.ncbi.nlm.nih.gov/genome/). However, the unprocessed sequence data are not very informative and they have to be annotated both at the structural level (identification of genes) and at the functional level (identification of gene function). Owing to the high cost and time required for manual genome annotation, genomes are generally annotated via automated gene prediction programs most of which are listed at the geneprediction.org web site (http://www.geneprediction.org/software.html). Annotation data obtained by this way may be utilized for both basic and applied research so that it helps to elucidate evolutionary relationships and develop better phylogenetic classification. Sequences of crop plants may aid in identification of economically important genes which in turn may help biologists to provide food, fiber, and fuel for the exponentially increasing population. As more whole genome sequences become available, it will increase the speed and lower the costs for studies regarding epigenomes, transcriptomes, and metabolomes. © Springer International Publishing Switzerland 2016.
