Additionally, the integration of metabolomics with genomics is gaining traction, as it can reveal how genetic variations influence metabolic pathways and contribute to phenotypic diversity. Understanding these complex interactions can lead to the development of trees with enhanced traits, such as improved growth rates and resistance to pests and diseases (Rajarajan et al., 2022). 9.2 Potential for new technologies and collaborative research The advancement of tree genomics heavily relies on the development and application of new technologies. High-throughput sequencing technologies, such as single-cell RNA sequencing, are poised to revolutionize our understanding of tree biology by enabling the study of gene expression at the single-cell level (Stephan et al., 2022). This level of resolution can uncover the roles of individual cells in complex tissues like wood. Another promising technology is CRISPR/Cas9, which allows for precise genome editing. This technology can be used to validate gene function and develop trees with desirable traits, such as enhanced wood quality or disease resistance (Cortés et al., 2020). Collaborative research is also crucial for advancing tree genomics. International consortia and interdisciplinary collaborations can facilitate the sharing of resources, expertise, and data, leading to more comprehensive and impactful research outcomes. For example, the Tree Bioinformatics Collaborative (TreeBioCollab) aims to develop standardized bioinformatics tools and workflows for tree genomics research, enhancing reproducibility and data integration across studies (Neale and Wheeler, 2019). 9.3 Funding and policy needs for advancing tree genomic research Advancing tree genomic research requires substantial funding and supportive policies. Funding is needed to support large-scale sequencing projects, the development of new technologies, and the establishment of long-term monitoring programs to study tree populations over time. Public and private funding sources should prioritize research that addresses critical challenges, such as climate change adaptation, forest health, and sustainable timber production (Sniezko et al., 2023). Policies should also support the open sharing of genomic data and promote collaborative research efforts. Establishing centralized databases for tree genomic data can facilitate data sharing and collaboration, accelerating scientific discovery. Additionally, policies that support the ethical use of genomic technologies and address public concerns about genetically modified organisms (GMOs) are essential for the responsible advancement of tree genomics. By aligning funding priorities and policies with the needs of the research community, significant progress can be made in understanding and harnessing the genetic potential of trees (Blais and Archibald, 2021). 10 Concluding Remarks The past decade has seen remarkable advancements in tree genome decoding, driven by the rapid evolution of high-throughput sequencing technologies and sophisticated bioinformatics tools. These advancements have enabled the sequencing of complex and large genomes of various tree species, providing insights into their genetic architecture and evolutionary history. For instance, next-generation sequencing (NGS) has facilitated the assembly of the first conifer genomes, revealing their intricate structures and the extensive presence of repetitive elements. Furthermore, genomic studies have identified numerous single nucleotide polymorphisms (SNPs) associated with critical traits such as disease resistance, drought tolerance, and growth rate, which are invaluable for tree breeding programs. The implications of these advances are profound, as they pave the way for developing more resilient and productive tree varieties, thereby enhancing sustainable forestry practices and biodiversity conservation. This study contributes significantly to forestry science and genetic research by integrating genomic data with ecological and evolutionary insights. By decoding the genomes of key tree species, we have provided a comprehensive understanding of the genetic basis of important traits, which is crucial for developing strategies to improve forest health and productivity. The identification of genetic markers linked to desirable traits enables
