In agriculture, leveraging knowledge of WGDs can aid in the development of crops with enhanced traits such as increased yield, stress tolerance, and disease resistance (Schranz et al., 2012; Ren et al., 2018). In conservation biology, recognizing the role of WGDs in species diversification can inform strategies to preserve genetic diversity and manage endangered species (Schranz et al., 2012). Future research should aim to translate the findings from WGD studies into practical applications that benefit both agriculture and biodiversity conservation (Schranz et al., 2012; Ren et al., 2018).By addressing these challenges and focusing on these research priorities, the scientific community can advance our understanding of WGDs and their profound impact on the diversification and adaptation of legumes and other plant lineages. 7 Concluding Remarks Whole genome duplication (WGD) events have been identified as significant drivers of genome complexity and species diversification in legumes. Multiple studies have confirmed the occurrence of WGDs in various legume lineages, including the Papilionoideae and Mimosoideae clades, which have experienced ancestral WGDs . These events have been linked to increased rates of diversification and the emergence of novel traits, which have facilitated the adaptation of legumes to diverse environments. Additionally, WGDs have been shown to result in the retention of duplicate genes that play crucial roles in essential cellular processes and regulatory functions, further contributing to the evolutionary success of legumes . The significance of WGD in legume evolution is underscored by its role in promoting genetic diversity and enabling the development of key traits that have allowed legumes to thrive in various ecological niches. WGDs have provided raw genetic material for evolutionary innovation, leading to the acquisition of novel phenotypic traits and enhanced adaptability. The timing of WGDs in relation to major climatic changes and the origin of symbiotic nitrogen fixation suggests that these events have been pivotal in shaping the evolutionary trajectory of legumes. Furthermore, the preferential retention of genes involved in transcriptional regulation and other critical functions highlights the importance of WGDs in maintaining genome stability and facilitating complex regulatory networks. Future research on WGDs in legumes should focus on elucidating the precise mechanisms by which these events contribute to species diversification and adaptation. Advances in genomic and transcriptomic technologies will enable more detailed investigations into the functional divergence of duplicate genes and their roles in legume evolution. Additionally, exploring the interplay between WGDs and environmental factors will provide deeper insights into how these events have shaped the evolutionary history of legumes. Continued comparative analyses across diverse legume species and their relatives will further our understanding of the evolutionary significance of WGDs and their impact on the diversification of this important plant family.
