The process is substrate- 21 dependent and powered by an actomyosin motor that drives the posterior 22 translocation of extracellular adhesins, which in turn propel the parasite forward. 23 Gliding motility is essential for tissue translocation in the sporozoite and ookinete 24 stages, however, the short-lived erythrocyte-invading merozoite stage has never 25 been observed to undergo gliding movement. Here for the first time we reveal that 26 blood stage Plasmodium merozoites use gliding motility for translocation in addition 1 bioRxiv preprint doi: https://doi.org/10.1101/2020.05.01.072637; this version posted May 3, 2020.
