主　　题：breeding breakthrough backbone 

摘      要：More than 600 species of conifers(phylum Pinophyta)serve as the backbone of the Earth’s terrestrial plant community and play key roles in global carbon and water *** coniferous forests account for a large fraction of global wood production,their productivity relies largely on the use of genetically improved ***,acquisition of such seeds requires recurrent selection and testing of genetically superior parent trees,eventually followed by the establishment of a seed orchard to produce the improved *** breeding cycle for obtaining the next generation of genetically improved seeds can be significantly lengthened when a target species has a long juvenile ***,development of methods for diminishing the juvenile phase is a cost-effective strategy for shortening breeding cycle in *** molecular regulatory programs associated with the reproductive transition and annual reproductive cycle of conifers are modulated by environmental cues and endogenous developmental *** evidence indicates that an increase in global average temperature seriously threatens plant productivity,but how conifers respond to the ever-changing natural environment has yet to be fully *** the breakthrough of assembling and annotating the giant genome of conifers,identification of key components in the regulatory cascades that control the vegetative to reproductive transition is ***,comparison of the signaling pathways that control the reproductive transition in conifers and the floral transition in Arabidopsis has revealed many ***,a more complete understanding of the underlying regulatory mechanisms that control the conifer reproductive transition is of paramount ***,we review our current understanding of the molecular basis for reproductive regulation,highlight recent discoveries,and review new approaches for molecular research on conifers.
