abstract = {An essential process in transmission of the malaria
parasite to the Anopheles vector is the conversion of mature
gametocytes into gametes within the mosquito gut, where they
egress from the red blood cell (RBC). During egress, male
gametocytes undergo exflagellation, leading to the formation
of eight haploid motile microgametes, while female gametes
retain their spherical shape. Gametocyte egress depends on
sequential disruption of the parasitophorous vacuole
membrane and the host cell membrane. In other life cycle
stages of the malaria parasite, phospholipases have been
implicated in membrane disruption processes during egress,
however their importance for gametocyte egress is relatively
unknown. Here, we performed comprehensive functional
analyses of six putative phospholipases for their role
during development and egress of Plasmodium falciparum
gametocytes. We localize two of them, the prodrug activation
and resistance esterase $(PF3D7_0709700)$ and the
lysophospholipase 1 $(PF3D7_1476700),$ to the parasite
plasma membrane. Subsequently, we show that disruption of
most of the studied phospholipase genes does neither affect
gametocyte development nor egress. The exception is the
putative patatin-like phospholipase 3 $(PF3D7_0924000),$
whose gene deletion leads to a delay in male gametocyte
exflagellation, indicating an important, albeit not
essential, role of this enzyme in male gametogenesis.},
