  • a In each strain, the percentages of cells with predominantly spherical, rod-like (length one to four times the width), and tubular (length more than four times the width) mitochondria are given. The mitochondrial morphology of DH1, the background strain in which the ΔfszA and ΔfszA ΔfszB mutants were constructed, was similar to that of AX3.
