Comprehensive Genomic Dataset of Chinese Lizardtail Herb and Comparative Genomic Analysis Provide Insights Into Its Paleo‐Polyploidization Event

Abstract: ABSTRACT The Chinese lizardtail herb, Saururus chinensis, holds a prominent position in traditional Chinese medicine. In this study, we present a comprehensive genomic dataset for S. chinensis. Furthermore, comparative genomic analysis indicates that the extant genome of S. chinensis retains extensive traces of a paleo‐tetraploidization event. These traces are observable at both the macroscopic level of chromosomes and the microscopic level within specific gene families, such as the PEL (pseudo‐etiolation in light) gene family. Additionally, our findings further suggest that this paleo‐tetraploidization event drives an expansion of the PEL gene family in the S. chinensis genome, potentially facilitating its neo‐ and sub‐functionalization, and thereby contributing to the evolutionary adaptability of this species.
