Advances and prospects of oak biology based on genomics
Oaks are important economic and ecological tree species in the northern Hemisphere, and are colloquially known as the “tree of life” or the “frame of civilization”. The publication of several oak genomes, such as those of Quercus robur, Q. lobata and Q. acutissima, has a profound impact on oak biology. In the past five years,numerous topics in oak biology have been investigated, including the systematic evolution and species identification, gene introgression and adaptive evolution, landscape genomics and ecological conservation, biological coexistence and interaction mechanism, secondary metabolism and growth and development, DNA methylation and epigenetic regulation, genes and longevity mechanisms. The expected development trends include four aspects: highlighting the in-depth application of oak genome resources, promoting extension of oak study systems, emphasizing topics in genetics and development for utilization of oak resources, and highlighting themes in ecology and evolution for conservation of oak forests.
