Magnolia lotungensis is an extremely endangered endemic tree in China. To elucidate the genetic basis of M. lotungensis, we performed a comprehensive transcriptome analysis using sample integrating plant’s bark, leaves, and flowers. De novo assembly yielded 177,046 transcripts 42,518 coding sequences. Notably, identified 796 species-specific genes enriched organelle gene regulation defense responses. A codon usage bias revealed that mutation appears to be primary driver selection shaping species’ architecture. An evolutionary based on dN/dS values paralogous orthologous pairs indicated predominance purifying selection, suggesting strong constraints most genes. comparative transcriptomic with sinica approximately 1000 ultra-conserved genes, essential cellular processes such as transcriptional regulation, protein synthesis, genome stability. Interestingly, only limited number 511 rapidly evolving under positive were detected compared kuangsiensis. These metabolic associated adaptation specific environments, potentially limiting ability expand its range. Our findings contribute understanding architecture suggest insufficient adaptive status.
