Cover photograph (Copyright © 2012, American Society for Microbiology. All Rights Reserved.): Localization of SPM1 to Toxoplasma gondii tachyzoite subpellicular microtubules. Stable cortical microtubules and the associated conoid were isolated by extraction in deoxycholate, and the resulting sample was stained with a Toxoplasma-specific tubulin antibody (red) and mouse antiserum that recognizes SPM1 (green). SPM1 localizes to the full length of the subpellicular microtubules but not the conoid which is located at the intersection of the subpellicular microtubules. (See related article on page 206.)
