Research Needs and General Conclusions

In this chapter we address the research needs in functional and evolutionary traits of WD based on the studies already done in this field. Wood formation is a complex process that is influenced by a variety of factors, including genetics, environment, and hormones. Wood density is an important wood quality trait that is influenced by both genetic and environmental factors. Recent advances in genomics and transcriptomicsTranscriptomics have provided new insights into the molecular mechanisms of wood formationWood formation.
