Identification and intracellular functional characterization of myosin XI and VIII in the lycophyte Selaginella moellendorffii.

ABSTRACT:

Main conclusion

Selaginella moellendorffii myosins retain conserved intracellular functions of known plant myosins, while lycophytes possess a unique myosin VIII with an extended neck domain. Research on plant myosins has primarily focused on model species, such as green algae, mosses, and seed plants. Here, we identified and cloned the myosin genes in Selaginella moellendorffii for the first time in the lycophytes. S. moellendorffii possessed two myosin XI genes and two myosin VIII genes. The cloned S. moellendorffii myosin (Sm myosin) VIII contained a neck domain approximately twice as long as those of previously identified plant myosin VIIIs. A BLASTP search using OneKP indicates that this myosin VIII is conserved throughout lycophytes. Transient expression of Sm myosin in Arabi
