How contemporary plant genomes originated and evolved is a fascinating question. One approach uses reference from extant species to reconstruct the sequence structure of their common ancestors over deep timescales. A second focuses on direct identification genomic changes at shorter timescale by sequencing ancient DNA preserved in subfossil remains. Merged within nascent field paleogenomics, these complementary approaches provide insights into evolutionary forces that shaped organization regulation modern open novel perspectives fostering genetic gain breeding programs establishing tools predict future population response anthropogenic pressure global warming.
