Research in the VanWinkle-Swift laboratory uses the Chlalmydomona monoica zygospore as a model for understanding cellular responses to environmental (abiotic) stress.

Approaches used in the laboratory include genetics (isolation and characterization of mutants), physiological studies, fluorescence and electron microscopy, biochemistry and molecular/cellular biology.

The mature Chlamydomonas zygospore has a massive, highly sculptured wall that provides protection from environmental stress including desiccation, freezing, mechanical abrasion and ultraviolet radiation.

Panel A shows a thin section of a zygospore viewed by transmission electron microscopy; Panel B shows the surface detail revealed by scanning electron microscopy.
