Transcriptome sequencing of alternative oxidase in Fusarium graminearum

The alternative oxidase is a ubiquinol oxidase found in plant mitochondria, as well as in the mitochondria of some fungi and protists. It catalyzes a cyanide-resistant reduction of oxygen to water without translocation of protons across the inner mitochondrial membrane, and thus functions as a non-energy-conserving member of the respiratory electron transfer chain. Its function has been reported in some organisms, but its function in Fusarium graminearum is still unclear. We knocked out the target gene by homologous recombination and studied its function.
