Cell morphology of strains LU-9, LU-20, LU-21 and LU-22. a Morphological analysis by optical microscopy (scale bars, 5 µm). b Morphological analysis by transmission electron microscopy (scale bars, 0.5 µm). The strain LU-20 with OLE1 overexpression maintained a spherical morphology, which is similar to that of the control strain LU-9. However, disruption of PAH1-DGK1 in LU-21 and LU-22 led to a distinctive elongated morphology
