Mp8g04010 MpMYOSIN_XI-2 experimental subject The single myosin XI gene of M. polymorpha (Mp8g04010), characterized in vitro and by heterologous expression in Arabidopsis. Its actin-sliding velocity (4.2 um/s) and ATPase activity resembled Arabidopsis myosin XI-2, it colocalized with ER along F-actin, and it rescued growth, cytoplasmic streaming and actin organization defects in Arabidopsis xi quadruple knockouts, indicating conserved motor function.
